Roof packaged Air conditioning Modules
With the continuing development in hermetic
Sepand Tahvieh’range of roof package units
compressor technology and the introduction of
is considerable with cooling capacities ranging
environmentally friendly refrigerants , roof pa-
from 15kw to a massive 42kw.
ckaged air conditioning is increasingly beco-
RMP units can be used individually or in pairs
ming the choice of both coach builder and tra-
to cover virtually all cooling requirements likely
in operator as the most convenient and cost
to be necessary to provide luxurious air condit-
effective method of providing air conditioning
ioning to passenger saloon areas. All Modules
to passengers.
are ideal for both new vehicles and for retro-fit
to existing cars. Their fully stainless steel construction combined with all copper heat exchanger coils makes them suitable for the most arduous climates. The use of fully hermetic compressors makes the unit virtually maintenance-free
between major overhauls. Twin compressors
employed within individual refrigeration circuits
allows independent compressor operation under thermostatic or in the unlikely event of compressor failure or refrigerant leakage. Air filters
are easily accessible from within the car and
can be changed in seconds.
We offer another Sepand Tahvieh Co' roof mounted
A/C model which is so suitable for train
set and LRV and any other passenger wagon which weight of A/C package is so important.
TRS roof mounted unit is considerable with cooling capacities ranging from 28kw to a massive 42kw.
Advantages of TRS
A/C unit:
-High reliability and low cycle life
-Totally self-contained, hermetically sealed
system
-Microprocessor-based controller
-Environmentally friendly refrigerant
-A wide range of capacities offered within
one low profile design
-Easy installation and low maintenance
-Ideal solution for retrofit applications as
well as new cars
Standard Features:
-Hermetic refrigeration circuits maximize reliability.
-Efficient scroll compressors offer greater reliability, reduced power consumption and lower noise
levels.
-Features latest microprocessor control system. Readily adaptable to customer's preferred refrigerant.
-kW for kW, the lightest air conditioning unit in the industry.
There is the other model which the air handling units with their fans, evaporators,
heating batteries, and filters, are located in
the roof area. The compressor and condenser can be installed underneath the car .
The air handling unit for roof installation has a particularly low profile in order to lose
as little ceiling height as possible. The fan
(a silenced version) with 2 radial impellers
evacuates the air and passes it via an evaporator and an electric heating battery into the roof ducts.
The compressor unit forms the core of the
refrigeration circuit. The compressor can
be semi-hermetical or open, depending on the type of power supply. We only use
proven series production units from wellknown compressor manufacturers, or in accordance with customer's particular requirements.
Under normal circumstances, the compressor unit is fitted with a capacity control.
The driving motor is supplied according to
existing power supply and usually incorporates overload protection.
The condenser
robust axial fans refriger-
ant collecting vessels and filter dryers, complete with the special finned heat exchangers. To facilitate cleaning of the heat exchangers, the fans and bottom plates can
be swung aside with a few easy hand movements.
Driver’s Cab Air Conditioning Systems
With Locomotive operators’ increasing efforts to
improve drivers’ environmental conditions and, in
consequence, reduce fatigue symptoms, Air Conditioning of Drivers’ Cab has become a normal fac-t
or to ensure both clean, fresh air at the right temperature.
Sepand Tahvieh range of Cab Air Conditioners
have been designed to meet a wide range of operators’ requirements and environmental conditions.
Under Frame Air Conditioning System
This system is formed of three individual
section s which consist of Compressor section
Condenser section and Air handling section and connection of units is by special pipes and
flanges, therefore installation and dismounting of the system are easily possible. All of the
sections are under frame mounted.
This system operates in high ambient temperature up to +50 C with high condense temperature up to +65 C .
At this system has been used of refrigerant R 134a ( recommended by international associations and for environmental protection) and using of this refrigerant is one of the advantages
of this system in comparison of its foreign analogous (which has used of refrigerant R12)
By using of very perfect and exact control
system Sepand Tahvieh Air conditioning
systems have ability of adjusting temperature in each of compartments individually
and by selecting of passengers between
22 C to 26 C. Also the unit con operate in
all seasons of year in temperature range
between -25 C to +50 C for outside air.
according to customer order Sepand Tahvieh
control system could be delivered as microprocessor systems and PLC.
Locomotive Static Inverter Air conditioning System :
This Air conditioning System is designed and manufactured for producing of standard and
suitable temperature of locomotive static inverter.
This system consist two main unit one out door unit which is installed on the roof of locomotive and the other indoor unit which is installed in the locomotive and on the inverter.
In manufacturing of all systems we use special equipments for security of passengers and
units in cooling and heating modes.
Sepand Tahvieh uses of good quality equipments with high credit brands from well-known
European and Western sources. For example compressor from Bitzer (Germany) and
Maneurope (France) and Valves from Danfoss (Denemark) and Alco (U.S.A).
We use the suitable software for calculation
Sepand Tahvieh Co. as up to 10 years
of heating and cooling loads and designs
study, design and manufacturing Rolling
of equipments and also designs of structure,
stock A/C systems is up to date of knowle-
FEA modeling, sheet metal design, thermal
dge of designing and manufacturing
system performance and balancing.
