The Smart Choice for Energy Efficiency
Th
he Smart Choice for Energ
performance, confi guration, and cost options as the 
ClimateMaster family of products offers. From our 
smallest horizontal unit in the GCH006, to our largest 
vertical in the GLV300, to our Rooftop series with 
available 100% make-up air (when mated with the Rx 
ERV), to the console, water-to-water, and two-stage 
Tranquility 27™, we have a unit to fi t your application. 
SOUND
Prior to the recently adopted sound standard ARI 260-
2000 there had been no standard for the evaluation of 
Water-Source heat pump sound per for mance. Also, those 
manufacturers who did generate and publish their own 
sound data, did so in their own labs making it diffi cult 
to have the data in de pen dent ly certifi ed and accurate 
comparisons were therefore, impossible. Now that a 
standard has been established, it is critical to compare the 
data correctly. If data from two man u fac tur ers is compared 
using different test procedures, results are not comparable. 
ClimateMaster has tested its product line for both ducted 
discharge and free inlet air combined with case radiated 
tests. Comfort has never been so quiet with our intelligent 
sound design. Our products use a variety of technologies 
to maintain our lead as the quietest units in the industry.
DUAL LEVEL VIBRATION ISOLATION
ClimateMaster units use an exclusive 
double isolation compressor 
mounting system. This dual level 
isolation deadens vibration and 
provides quiet operation.
TORSION-FLEX BLOWERS
Blower motors ,on select models, 
are mounted with a unique torsion-
fl ex mounting system which not 
only allows for easy service, but also 
reduces vibration from the blower 
motor during operation.
ULTRAQUIET
ClimateMaster’s optional additional sound suppression 
package enhances our already excellent sound 
performance through the use of dual density acoustical 
insulation and other strategically placed sound 
attenuating materials. No other manufacturer’s mute 
package comes close to matching the performance of 
the UltraQuiet package. 
E-COATED AIR COILS
All ClimateMaster Water-Source 
heating and cooling systems 
(excluding the RE series rooftop) 
are available with an E-Coated air-
coil option. This process provides 
years of protection against coil 
corrosion from airborne chemicals 
resulting from modern building 
material outgassing and most 
airborne environmental chemicals. 
In fact, ClimateMaster’s exclusive E-Coated air-coils 
enhance corrosion protection to nearly 20 times that of a 
traditional uncoated coil.*
* Test based upon ASTM B117 Salt Spray test hours.
CLIMADRY REHEAT
Continuing to lead the industry in IAQ (Indoor Air Quality) 
solutions, select ClimateMaster units are available with 
an innovative method (patent pending) of reheating 
the air. The ClimaDry microprocessor-controlled option 
will automatically provide 100% reheat by adjusting 
the amount of reheat capacity based upon supply air 
temperature. This new approach to reheat provides 
dehumidifi ed, neutral temperature supply air, while 
eliminating the problem of overcooling the space when 
loop temperatures drop. All components are internal to 
the unit, saving space and keeping installation costs low. A 
simple humidistat or DDC controls activates the option. 
VOLTAGES
ClimateMaster units are available in a wide variety of 
commercial voltages, providing maximum fl exibility in 
building design. Available voltages are as follows:
• 208-230/60/1
• 208-230/60/3
• 265/60/1
• 460/60/3
• 575/60/3
• 220-240/50/1
• 380-420/50/3
*  Not all units are available with every voltage combination shown above.
ACCESSORIES
ClimateMaster offers a complete line of accessories to 
complete any project, including hoses, thermostats, valves, 
pumps, fi ttings, controllers, sensors, fi lters and more.
