AQUARIUS Plus 2
1. General
The Aquarius Plus 2 series of chillers and heat pumps with reversible
facility on the hydraulic side are high efficiency water cooled
packaged units (Eurovent A Class). The Aquarius Plus 2 series uses a
dry expansion type single pass shell & tube evaporator with a
refrigerant circuit for each compressor and a single water circuit, one
or two semi-hermetic dual screw compressors and continuous
control of cooling capacity serving independent refrigerant circuits,
electronic expansion valves and R134a refrigerant. The condensers
(one for each refrigerant circuit) are shell & tube type and are
suitable to integrate partial or total heat recovery. Installation is
usually indoors, although the units are also suitable for outdoor
installation under a rain shelter (IP54).
The units are managed by a microprocessor controller, through a
simple user interface allows a fully independent control of all the
main functions, including adjustments and alarms. All units are
designed, built and checked in compliance with ISO 9001 and
incorporate components sourced from premium manufacturers.
The combinations of these solutions make it possible to enhance
energy efficiency at partial loads, which account for the largest
proportion of the working life of an air conditioning unit, thereby
maximizing ESEER (*) seasonal performance values.
The standard product, destined for EU and EFTA countries, is subject
to the following directives:
42%
- Electromagnetic Compatibility Directive 2004/108/EC;
- Machinery Directive 2006/42/EC;
- Pressure Equipment Directive 97/23/EC.
- The electrical equipment is constructed in compliance with EN
60204-1.
All data in this catalogue refer to standard units and nominal
operating conditions (unless otherwise specified).
(*) The ESEER (European Seasonal Energy Efficiency Ratio) index
proposed and used in the European design context, characterize the
average weighted efficiency of a chiller for air conditioning
applications. Both indices express, far more accurately than EER, the
ratio between the useful effect (energy removed from interior spaces)
and energy expenditure (electrical energy consumed) of a chiller
during an entire season of operation. In relation to the various
different operating conditions and the frequency with which they
occur, these indicators are calculated by assigning a different energy
weight to the corresponding output values of the unit.
For example ESEER = 6 means that during an entire season of
operation 1 kWh of electrical power is required on average to remove
6 kWh of heat energy from the air conditioned spaces.

4. Testing
All units are tested in a test chamber in order to check correct
operation. The main checks performed are as follows:
•the correct instalment of all components and the lack of refrigerant
leaks;
•electrical safety tests as prescribed by EN60204-1;
•correct operation of the microprocessor and correct values of all the
operating parameters;
•the temperature probes and pressure transducers.
AQUARIUS Plus 2
The Aquarius Plus 2 range, in order to meet different installation
requirements, are available with different versions and accessories:
At the time of installation the units require exclusively electrical and
hydraulic connection, thus maximising reliability levels.
Installation of a filter on the unit inlet is mandatory.

5. Compressors
The units of the Aquarius Plus 2 range are equipped with semihermetic dual screw compressors optimized for use with R134a
refrigerant.
The compressors operates on independent refrigerant circuits; this
allows to deliver the exact cooling capacity required by the system
achieving and high energy efficiency special at partial loads, which
account for the largest portion of the working life of the air
conditioning application. The compressors can deliver down to 25% of
the nominal cooling capacity in the single circuit units and down to
12.5% in
the units with two compressors.
The new "Smart Stepless” software algorithm developed by MTA
determines with greater precision the real position of the compressor
capacity slide and therefore its cooling capacity, compared to the
traditional capacity logics; current and average partialization
percentage are also available on the display.
In addition, even in situations of high variability in the thermal load,
the electronic control independently adjusts the capacity speed
according to the needs of the system in a manner that is transparent
to the user, with consequent greater stability of the evaporator outlet
water temperature.
Lubrication of the mechanical parts is ensured by a high-efficiency
separator that is built into the compressor that reduces the outflow of
the oil towards the system and the presence of an appropriate sightglass that enables control of the oil level in the casing. Each
compressor is equipped with two oil level sensors: the upper sensor
has the function of pre-alarm and is activated for necessary and
relevant operational logics for a better return of the oil to the
compressor, while the lower sensor has a function of alarm and
shutdown the unit in the event of intervention.
The electric motor with star-delta starting (soft-starter optional) is
two-pole type cooled by the intake gas; protection from possible
overheating is ensured by an internal module that controls the
temperature of the windings; the same module also controls the
sequence of the phases to avoid the danger of reverse rotation and
the compressor’s discharge temperature.
Each compressor is equipped with a crankcase heater, a delivery
shut-off valve and a check valve in delivery side in order to prevent
liquid return.
The compressors are easily accessible for normal routine
maintenance and are mounted in the upper part of the machine on
rubber vibration dampers. The unloading function allows starting
of the system and the operation of the machine, even under
conditions that are very different from the nominal ones.

6. Evaporator
The evaporator is of the dry expansion single pass shell and tube type
with one or two independent refrigerant circuits and a single water
circuit. The evaporators in the Aquarius Plus 2 series are specifically
designed for use with R134a and are composed of a bundle of copper
tubes mechanically expanded at the ends into a tube plate and
housed inside a carbon steel shell. The refrigerant flows inside the
copper tubes, which are ribbed to increase the exchange efficiency,
whilst the water, which is oriented by baffles, flows over the outside
of the tubes.
Each evaporator is externally protected with thermal insulation
material and anti-condensation cladding with black embossed finish,
and protected from the risk of freezing potentially caused by low
evaporation temperatures by antifreeze function incorporated in the
electronic controller, which monitors the water outlet temperature.
The “LWT” units are fitted with an evaporator optimized for working
with brine; an additional thermal insulation is provided in order to
avoid potential condensation problems. Each evaporator is equipped
with a water differential pressure switch to protect it in conditions in
which the water flow is absent or insufficient. The water connections
are easily accessible from the exterior of the unit and are “Victaulic”
type, supplied with stub pipe.
All the evaporators comply with the “EC” pressure vessels directive
and can handle antifreeze solutions and, in general, all other liquids
that are compatible with the hydraulic circuit construction materials.
7. Condensers
The condensers, one for each refrigerant circuit, are of the shell and
tube type and are optimised for the use of R134a refrigerant.
The exchangers are composed of a bundle of copper tubes (inside
which water flows), housed inside a carbon steel shell, in which
condensation occurs. The cast iron headers of the shell carry the
threaded connections for the hydraulic pipes and are removable in
order to allow inspection and the internal cleaning of the tubes; the
tubes are finned on the water side to enhance thermal exchange
efficiency.Installers are required to fit a filter on the unit inlet line to
intercept any debris. If the installation involves the use of water at the
inlet to the condensers outside the values specified for the operating
limits, pressure control valves must be fitted. All the condenser
comply with the “EC” pressure vessels directive and can handle
antifreeze solutions and, in general, all other liquids that are
compatible with the hydraulic circuit construction materials. The
user is responsible for interconnection on the water side of dual
circuit units and, when the unit is to be used as a heat pump,
positioning of the winter temperature control probe (always supplied
pre-wired to the controller) in a socket on the condenser outlet pipe.
8. Partial and total heat recovery (optional)
• D - partial heat recovery: by means of a specifically developed
condenser, while the unit is on cooling mode, it is possible to recover
part of the condensing energy for the production of hot water. Heat
recovery takes place simply via activation of the flow of water in the
relevant area of the exchanger. The interconnection, temperature
probes and management of the pumps are at the customer charge.
The use of partial recovery is not permitted in HP mode.
configuration offers significant energy saving whenever the requested
of hot water is high. Total recovery mode is activated by turning on the
hydraulic pumps in the relevant area of the exchanger. With this
solution the condenser and the delivery pipes are supplied thermally
insulated, while the interconnection and the temperature probes are
at customer charge. Management of the pumps and of the alarms is
entrusted to the xDRIVE electronic control. This option is not
compatible with the heat pump configuration (HP).
• R - total heat recovery: by means of a specifically developed
condenser, while the unit is on cooling mode, it is possible to fully
recover the condensing energy for the production of hot water. This
Each cooling circuit in the standard configuration is completed in the
following manner:
•electronic expansion valve that allows the improvement of cooling
performance in a context that is much wider than mechanical
thermostatic valve, a reduction of the fluctuations of the temperature
of the water and a great precision during operation at partial loads;
•filter-dryer;
•sight-glass;
•shut-off valve and check valve on the compressor delivery;
•shut-off valve on the liquid line;
•pressure switches for control of the maximum condensation
pressure as provided by the European standards (EN378);
•safety valves on the low and high pressure line (as envisaged by
EN378);
•low pressure transducer: for alarm management, read and display
the evaporating pressure;
•high pressure transducer: read and display the condensing
pressure; alarms management; unloading function; for adjustment
of the condensing pressure through servo-driven modulating valve
(optional);
•antifreeze oil and refrigerant charge.
The refrigeration circuit of the LWT version includes a liquid injection
system on the compressor; this consists of bleeding from the main
liquid line of a small amount of refrigerant that is directly expanded
within the compressor thus allowing control and limitation of the
discharge temperature of the compressors.
The entire brazing for connection of the various components is made
with silver alloy and the cold pipes are coated with heat-insulation
material to prevent the formation of condensation.
10. Structure and casing
The Aquarius Plus 2 units are characterised by a self-supporting
structure developed in order to allow the maximum accessibility to all
the components for ordinary maintenance. The heat exchangers are
painted and rigidly assembled and form an integral part of the
structure and support the compressors and the electrical panel. The
base, heat exchangers and the support structure of the compressors
are black RAL 9005, while the electrical panel and the panelling of the
silenced acoustic version (optional) are light grey RAL 7035 with
orange-peel finish made from galvanised carbon steel plating.
All of the components are subjected to a treatment of phosphor
degreasing treatment and oven painting at 180 °C with polyester
powder coating to provide a durable weatherproof finish.
The units are equipped with eyebolts for lifting and movement via the
4-point sling bar.

11. Electrical panel
The unit and the electrical cabinet are made in compliance with CEI
EN60204-1 (Safety of machinery – Electrical equipment of machines
– Safety Part 1: General rules); in particular, protection against the
weather is ensured such as to allow outdoor installation of the
chillers protected by a rain shelter.
The IP54 protection is assured thanks to a seal and a fully welded
cabinet, where the electrical devices are placed on a base plate; an
easy access to all the device is ensured by a double door where there
is the display of the electronic control which is protected by a
transparent polycarbonate door.
The electrical cabinet, with forced ventilation, is equipped with a main
breaker with door lock device and contains the circuit breakers to
protect the compressors and contactors for star-delta starting; the
control section includes a transformer for the control circuits and the
microprocessor board.
The protection from the phase loss and from the phase reversal is
assured by the phase monitor device.
The units are also electrically prearranged for connection of a flow
switch and the pump’s management is available for all the
configurations.

12. Control
AQUARIUS Plus 2
Control and management of the unit are provided by a MTA's control
system "xDRIVE" composed by microprocessor electronic controller
connected to the semi graphic backlit user terminal; the latter has a
240x96 pixel screen, 8 unit programming buttons and buzzer. Thanks
to the icons, multi-function keys with dynamic description and
moving images, the displays and information are easy to interpret, by
both trained personnel and the system operator even if not specifically
trained on the use of the controller.
The terminal is located on the door of the electrical cabinet and is
protected by an openable polycarbonate cover. An USB port placed
near the display allows the software update and the download of the
alarms history.

13.1 Options
The options must be specified at the time of the order because they
are factory fitted:
Compressors
• soft starter: these devices reduces inrush current during startup of the compressors; the soft starter allows to preserve the
compressors by mechanical stress, with a reduction of
maintenance and downtime; units equipped with soft starter can
operate up to a maximum ambient temperature of 40 °C, after
which, the unit will enter in a safety mode, in order to preserving
the operation of the machine; soft starter aren’t suitable
combined with capacitive elements and power factor correction
systems must not be operated simultaneously with them. For
models 3301 and 6602, this option is available on request only
(special execution);
• capacitors for compressor power factor correction at cosϕ > 0.9
located in an electrical box installed on the rear side of the
electrical panel; this option is not compatible with the soft starter
devices.
Heat recovery:
• D - partial heat recovery (see relevant chapter);
•R
- total heat recovery (see relevant chapter);
Acoustic configurations :
• Silent acoustic configuration: optimised for very low noise
operation, it allows a reduced noise levels by approximately 6
db(A) compared to “Basic” version.

• compressor shut-off valves on suction line to help service task;
for models 3001, 3301, 5602, 6002 and 6602, this option is available
on request only (special execution);
9
13.2. Kits
The kits are supplied separately, generally at the same time of the
unit, and installed by the user. They can be supplied later as spare
parts, modification kits, completion kits, etc.:
• anti-vibration mounts;
• Victaulic to flanges evaporator conversion kit;
• threaded to flanges condenser/total heat recovery conversion kit;

0-10V signal supplied by the unit controller.
The choice of valve is made on the basis of the water flow rate in each
condenser and the maximum closing and adjustment pressure
differentials, exclusively for modulating valves, using the "Pressure
control valves" and "Modulating valves" tables. Each kit has a single
valve for each condenser and includes threaded counter-flanges
complete with seals. The user is responsible for installing the valves:
installation of support brackets, connections and hydraulic unions
(the diameter of the threaded connections may not correspond to the
diameter of the condenser connections), refrigerant (pressure control
valves) and electrical (modulating valves) connections.

13.3 Special executions
AQUARIUS Plus 2
This is a selection of the most popular special features, normally not
described in detail in our catalogues; the feasibility of special designs
must be assessed, confirmed, and priced on a case by case basis in
communication with our sales offices before placing the order:
10
• very high energy efficiency versions;
• 460 V / 3 ph / 60 Hz power supply;
• condensers suitable for sea water.
Selection guide
1) Observe the operational limits as indicated in the chart “Working
limits”;
2) Verify that the cool water flow is between the minim and maximum
values of water flow, which are described in the “Hydraulic data”
table. A very low flow can cause laminar flow and thus danger of
ice formation and poor unit control; a very high flow can cause
great pressure drops and the possibility of tube failure inside the
evaporator;
3) For working temperatures under 6 °C outlet water it is necessary
to add ethylene glycol or any other antifreeze additives. Consult the
chart “Solutions of water and glycol” to determine the necessary
quantity of ethylene glycol, the reduction of cooling capacity, the
increase of power absorbed by the compressors, the increase of
evaporator pressure drop due to the presence of the ethylene
glycol;
4) When the difference in temperature between water inlet and outlet
is different from 5 °C, the cooling/heating capacity and the
absorbed power must be corrected using the table “Corrective
coefficients ΔT ≠ 5 °C”.

FLI: max power absorbed in the working limits condition (kW);
FLA: max current absorbed in the working limits condition (A);
ICF: start-up current at the start of the last compressor in the working limits condition.
Compressors starting with soft starter: the soft starters allow a reduction of peak current during start-up of the compressors;
these devices allow then to preserve the compressors by mechanical stress, with the consequent reduction of maintenance and
machine downtime. The units equipped with a soft starter can operate up to a maximum ambient temperature of 40 °C, after which,
the unit will enter in a safety mode, in order to preserving the operation of the machine; soft starters are't compatible with capacitive
elements; power factor correction systems cannot operate simultaneously with the soft starter. This option is factory fitted and must
be specified in the order.

tu: evaporator outlet water temperature (°C);
Pf: cooling capacity (kW);
Pa: total absorbed power (kW);
Fw: water flow rate with ΔT = 5 °C (m3 /h).
(*): The performances have been calculated with 20% ethylene glycol in the water.
(**): Condenser maximum outlet water temperature. When the condenser temperature is higher than the "t max" the unit doesn't stop
but the "unloading" system capacity control is activated.
The values in the table are inclusive of ethylene glycol percentage and are calculated with ∆T = 5 °C evaporator and condenser ∆T = 5 °C.
To calculate performances at diferring water inlet/outlet ∆T levels, refer to the "∆T correction factors" table. Interpolation is allowed,
extrapolation is not permitted.
In the HP (heat pump) and R (total heat recovery) operating mode the heating capacity is detemined with the following formula: Heating
capacity = Cooling capacity + Total absorbed power.

INSTALLATION GUIDE
Installation of the units described in this catalogue must be performed in observance of the following prescriptions:
a) Install the unit in a perfectly horizontal position to ensure correct oil return to the compressors.
b) Maintain the specified clearances around the unit.
c) Where possible, install the machine in a way to minimise the effects of noise, vibration, etc. In particular, do not to install the machine
in areas where the noise could cause nuisance as under windows or between two residences. The vibrations transmitted to the ground
must be reduced by using anti-vibration mounts, flexible joints on the water pipelines and on the conduit containing the cable of the
electrical supply.
d) Electrical installation works must be carried out by a specialist in accordance with the wiring diagrams and in compliance with the current
regulations in force in the country where the unit are installed.
e) Make the hydraulic connections, installing the following:
- flexible couplings;
- shut-off valves;
- bleed valves in the uppermost sections of the plant;
- safety valve;
- grain valves in the lowermost points of the plant;
- pump and expansion tank;
- flow switch;
- metal mesh filter with the mesh size not exceeding 1 mm installed on water inlet side of the evaporator and condensers, in order to protect
the heat exchanger from impurities present in the system.
f) If the total volume of the hydraulic circuit is insufficient, install a water storage tack down-line from the user side exchanger; the storage
tank serves to reduce the range of fluctuations of chilled water temperature while simultaneously optimising the energy efficiency of the
unit. The following table shows the minimum water contents of the installation referred to nominal operating conditions, with the standard
settings of the electronic controller parameters:

g) In the case of cooling capacity requirements that are higher than the maximum capacities available with a single unit, the chillers can be
connected in parallel on the hydraulic circuit, ideally selecting identical units in order to avoid situations of imbalance of water flow rates.
h) If it is necessary to treat water flow rates that are higher than the maximum permissible flow rate associated with the unit, it is advisable
to set up a by-pass between the chiller inlet and outlet.
i) If it is necessary to treat water flow rates that are lower than the minimum permissible flow rate associated with the chiller, it is advisable
to set up a by-pass between the chiller outlet and inlet.
l) Carefully bleed all air from the hydraulic circuit because even a small amount of air the circuit can cause the evaporator to freeze.
m) Always drain the hydraulic circuit during winter shutdowns; alternatively, ensure the circuit is filled with a suitable antifreeze solution.
