Description
UP condensing units and heat pumps are completely assembled,
piped and wired at the factory to provide a single-piece unit for
shipment and rigging. Each unit is pressurized with a holding charge of
refrigerant R-410A for storage and/or shipping.
The compact design, clean styling, small footprint, and quiet operation
make these condensing units and heat pumps suitable for almost any
outdoor location. On rooftops... because they weigh much less than a
single package unit of similar capacity and are much easier to rig and
support. On the ground... because the footprint is compact allowing a
variety of applications.
Both the UP condensing units and heat pumps are equipped with
reliable Smart Equipment™ microprocessor controls to assure proper
operation and unit protection for long product life. Products from 10 to
20 tons are available in single or dual (2 or 4 pipe) refrigerant circuits
for redundancy in operation and various application choices such as
one outdoor unit matched with two indoor units.
The UP air handling units are completely assembled units, including a
well-insulated cabinet, a DX cooling coil with copper tubing, aluminum
fins, expansion valve(s), distributor(s), 2" throwaway filters, a
centrifugal blower, a blower motor, an adjustable belt drive, a blower
