DESCRIPTION
This 20 ton evaporator blower is designed with two distinct
modules to provide maximum application flexibility. The units
are shipped as single packages with the blower module
mounted on top of the coil module, but the blower module can
be repositioned in the field to meet almost any installation
requirement.
The blower module includes the blower wheels and room for a
field-mounted motor and drive. The coil module includes direct
expansion coils, one-inch throwaway filters, 1 liquid line
solenoid valve for 50% capacity reduction, thermal expansion
valves, distributors and a condensate drain pan.
Each evaporator coil is pressurized with air to 325 psig and leak
tested under water. After the headers are brazed onto the coil
and the coil is installed in the unit, the coil will be pressurized
with a combination of refrigerant-22 and nitrogen to 150 psig for
pressure testing and additional leak testing. After the coil is
evacuated and dehydrated, it will be pressurized with a holding
charge of refrigerant-22 for storage and/or shipping.
A supply air plenum, return air grille, steam coil, hot water coil,
base section, suspension hardware, blower motors and drive
accessories are available for field-installation to provide
additional application flexibility.
This evaporator blower, applied with a matching condensing
unit, will provide years of quiet, efficient and dependable
operation.
FEATURES
APPLICATION FLEXIBILITY
- This evaporator blower can be
arranged for a variety of air discharge patterns in either the
horizontal or the vertical position.
The following illustration shows three of the more common
installation arrangements. Refer to the unit installation
instruction for other possibilities.
The unit can be bottom-supported or ceiling-suspended and
can be arranged to meet almost any space or duct
requirements. Each unit is available with a choice of blower
motors, drive packages plus other accessories to make them
suitable for most applications.
PART LOAD OPERATION
- The unit requires no field
modifications for part load operation. Capacity reduction not
only provides economical operation but also maintains more
even temperature and humidity levels in the conditioned
space.
