TECHNICAL OVERVIEW
Revolution® Series HXT Multi-Positional Vertical Two-Stage Packaged Unit
ENERGY STAR® requirements,
government regulations, and
competition continue to drive the
geothermal industry to provide higher
efficiency levels and greater equipment
reliability. Overall, this is good for the
customer and the environment. These
challenges, however, are difficult to
meet in some parts of North America,
where indoor air quality and/or airborne
chemicals cause premature indoor
air coil failure (both conventional
air conditioners/heat pumps and
geothermal systems). Many failures
are attributed to formicary corrosion,
which is a type of corrosion that occurs
as airborne chemicals mix with the
condensation on the coil to form certain
acids that aggressively attack copper
tubing.
Hydron Module HXT units (2-6
tons) are built with a standard allaluminum, microchannel air coil.
This technology provides a solution that
can meet the efficiency and reliability
requirements while eliminating the risk
of failure from formicary corrosion.
Other benefits include:
n Single material construction (all
aluminum vs. copper/aluminum),
eliminating the corrosion potential
caused by dissimilar metals
n Improved heat transfer and thermal
performance, resulting in increased
unit efficiencies and lower operating
costs
n 40% less material than a standard
tube-and-fin copper/aluminum coil,
which saves on unit weight and is also
fully recyclable
n Enhanced structural robustness (less
chance of damaging a fin simply by
changing the unit’s filter)
Other Standard Features
n Quadruple compressor isolation (high density steel/foam layer, rubber
grommets, and two layers of insulation) provides excellent sound/vibration
absorption.
nCabinet design features a foamed-in, water-to-refrigerant coaxial heat
exchanger that not only prevents condensation, potentially leading to premature
failure, but also includes a sleeved opening for downflow configuration. This
feature means higher reliability and less SKUs.
n Top-mount control box provides eye level access for easier wiring and service, and
also allows the unit to be installed as left hand or right hand return.
n XT Vertical Packaged models are available in both residential and commercial
voltages – 208/230 V, 60 Hz, Single and 3-phase; 460 V, 60 Hz, 3-phase. Consult
engineering documentation for complete model information and selection
guide.

Downflow Conversion
Downflow conversion may be accomplished in the field
with an optional downflow kit and a few installation
steps. Simply add the downflow plenum, insulate the
plenum, rotate the blower, and reconnect any wiring.
There is no longer a need to stock upflow and downflow
units. One model does it all. Plus, the unit can be
installed as either right hand return or left hand return.
One unit replaces four!
