Carrier: Turn to the Experts.
Packaged Water-to-Air Heat Pumps
Carrier Geothermal has a number of choices for packaged
geothermal heat pumps with airfl ow confi gurations for most any
installation. Three families of two-stage products are available.
Those are the GT-PC (50YG), GT-PX (50YD), and GT-PB (50YF).
The GT-PC (50YG) and GT-PB (50YF) series include the Two-Way
Unit Communicating System and the Integrated Variable Speed
Water Flow Control. All three families include a variable speed
ECM blower and a two-stage Ultra scroll compressor. GT-PC
(50YG) and GT-PX (50YD) products are available in sizes 026 to
072 (7.6 to 21.1 kW) in upfl ow, downfl ow, or horizontal supply air
confi gurations. GT-PC (50YG) and GT-PX (50YD) products are
industry leaders with effi ciencies among the highest in the industry,
unique cabinet features, and unsurpassed quality. GT-PB (50YF)
products are available in sizes 024 to 060 (7.0 to 17.6 kW) in
upfl ow or horizontal supply air confi gurations. GT-PC (50YG), GT-
PX (50YD), and GT-PB (50YF) series units are designed with Zero
Ozone Depletion Puron® (HFC-410A) refrigerant.
GT-PG series, the single stage version of Puron packaged units, are
available in sizes 018 through 070 [5.3 to 20.5 kW]. The GT-PG
series is available with upfl ow, downfl ow and horizontal supply
air options, plus left- or right-hand return air options. The ECM
variable speed fan motor is optional for GT-PG units.
Optional HWG (Hot Water Generator), Whole House
Dehumidifi cation, and numerous other options and accessories
create a broad product offering for customers demanding the most
from their heating and cooling systems.

Split Systems Water-to-Air Heat Pumps
Split system heat pumps add even greater fl exibility to Carrier
Geothermal’s broad product line. Whether the installation involves
replacement of an older heating and cooling system or is new
construction, the split system allows geothermal installations where
a packaged unit may not be practical.
The GT-PCS (50YGS) indoor split units are typically placed in a
basement, garage, closet or mechanical room, allowing the air
handler to be located where it’s most convenient. For example, a
narrow closet may not be large enough for a packaged unit, but
may accommodate an air handler. Split systems also work well
when a top return/bottom discharge arrangement is required.
GT-PCS (50YGP) outdoor splits provide an excellent retrofi t
option as the units are suitable for outdoor replacement of an
existing AC or ASHP, providing increased effi ciency.
Replacement geothermal applications with dual fuel heat pumps
generally handle 80% to 100% of the heating load, which in
many cases may cut heating and cooling costs in half. A dual fuel
system allows the customer to keep the existing furnace, and
avoid upgrading the electrical service in most situations. Plus, the
higher effi ciencies in cooling and the optional hot water generator
contribute to a quick return on investment.
