DESCRIPTION
R
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 UPG coils utilize a TXV to provide our customers
with the optimum performance and refrigerant control required for
13+ SEER systems. Coils can be ordered with a R22 TXV factory
installed that can be easily converted to R410A by changing the bolt-
on TXV.
"Flex-coils" are also available without a factory installed metering
device. For added application flexibility a R22 or R410A TXV is
installed, on "Flex-coils", in the field to meet your refrigerant choice.
Upflow/Downflow Coils Full Cased and Partial Cased
Coils –
Designed for high-efficiency to match any system, full cased
in the upflow or downflow and the partial cased in the upflow only
.
application
Multi-Position Coils -
upflow/downflow coil but with the added flexibility that allows it to be
installed any position, upflow, downflow, horizontal right or left. This
coil can be easily applied to our furnace and modular air handler in
any configuration.
Horizontal Duct Coils -
dedicated horizontal, slab coil, applications. Field transition may be
.
required
Dedicated Horizontal Cased Coils –
only or heat pump approved for horizontal furnace or modular air
handler applications. Unlike the horizontal duct coils these cased
coils match the dimensions of the furnace or modular blower
FEATURES
Thermal Expansion Valve -
coil to R22 or R410A refrigerant. A true bolt-on TXV, valve assembly
and equalizer tube are bolt-on, no brazing required. TXV and sens-
ing bulb are mounted inside the cased coil cabinet. (Must be field
supplied for all "Flex-coils")
MicroBlue™ Coated Fins -
MicroBlue™ Hydrophilic coating to enhance the removal of conden-
sate during the refrigeration cycle and reduce the possibility of water
blow-off. The MicroBlue™ coating also reduces the growth of germ
causing microbes.
Insulated Cabinet -
lated with foil faced insulation to prevent sweatin
fiberglass turfskin insulation.
Internally Clean -
dehydrated, sealed and shipped with a holding charge. The suction
and liquid lines are sealed with rubber plugs, no cutting of connection
stubs to attach line set
Durable Finish Inside and Out -
painted steel. The pre-treated flat galvanized steel provides a better
paint to steel bond, which resists corrosion and rust creep. All inter-
nal metal parts are made of G90 pre-painted steel i.e. triangular
plates, top plates, horizontal supports etc. (Coil header plates are
non-painted due to the brazing process during production.)
Optimum Heat Transfer -
nology, staggered rows of copper tubes are mechanically expanded
into aluminum fins to provide optimum air to surface contact for
ample moisture removal as well as high performance ratings.
ACCESSORIES
Refer to Price Manual for specific model numbers
TXV Kits -
Thermal expansion valve kits are available for "Flex-coil"
applications and converting R22 to R410A refrigerant or as a service
replacement. All TXV kits are non-braze
including the valve assembly and equalizer tube. (No orifice or any
other metering device is to be used in conjunction with the TXV).
Coil Casing Without Coil –
width that can be installed with the furnace or modular air handler
during initial installation. This option is available to allow the installer
the flexibility to install the coil at a later date without duct modifica-
tions.
