Description

Series 20 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 Series 20 condensing units and heat pumps are equipped
with reliable Simplicity® 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 Series 20 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
motor contactor and a small holding charge of nitrogen.
Units are shipped in the vertical position ready for field installation, but
can be easily converted to horizontal position. An added benefit of the
Series 20 air handling units is they
are designed to operate with either
a condensing unit or a heat pump
and no field modification or special
unit is required for heat pump
applications.
