DESCRIPTION
These cooling and heat pump coils are designed to be
installed with UPG furnaces and to be matched with UPG
cooling and heat pump outdoor units. All coils are available
as sweat-connect models for your convenience and ease of
matching.
Upflow Coils - Available in high-capacity models to match
any system and upflow furnace. Models available with factory
installed TXV or orifice metering system.
Multi-Position Coils - Available in high-capacity models to
match any system and any multi-position furnace and air
handler. Models available with factory installed TXV or orifice
metering system.
Horizontal Duct Coils - Available to match any cooling or
heat pump system and horizontal furnace. Field transition
may be required.
Dedicated Horizontal Cased Coils - Available to match
most cooling or heat pump systems and any horizontal gas
furnace or modular air handler. For horizontal application
only. Models available with factory installed TXV or orifice
metering system.
FEATURES
Insulated Cabinet - All evaporator coil cabinets are thermally
insulated to prevent sweating.
Internally Clean - All evaporator coils are factory leak-
tested, dehydrated, sealed and shipped with a holding
charge.
Durable Finish - Coil casings are made of pre-painted steel.
The pre-treated flat galvanized steel provides a better paint to
steel bond, which resists corrosion and rust creep.
Optimum Heat Transfer - Using the latest in heat transfer
technology, staggered rows of rifled copper tubes are
mechanically expanded into aluminum fins to provide opti-
mum air to surface contact for ample moisture removal as
well as high performance ratings.
Optional Factory Installed Thermal Expansion Valve -
Provides flexibility to match high efficiency applications at a
lower installed cost.
Yorkmate Refrigerant Control - Provides optimum system
performance and the flexibility to match coils with any effi-
ciency level cooling or heat pump system.
ACCESSORIES
Refer to Price Manual for specific model numbers.
TXV Kits - Thermal expansion valve kits are available for
indoor coils to obtain specific system performance.
Horizontal Drain Pan Kits - A field installed horizontal drain
pan kit (1HP0623BK or 1HP0628BK) is available for horizon-
tal applications on the multi-position coil. The full cased multi-
position coil is also available with a factory installed horizon-
tal drain pan option.
