COMPLETE
FACTORY PRE-PIPING OF ALL VALVES
All extra system components such as liquid line solenoid valve,
evaporator TXV (thermostatic expansion valve), check valves, hot
gas solenoid valve, three-way valve, and crankcase pressure regulator
are all installed and pre-piped at the factory. This results in
a faster and simpler system installation with significant savings
on installation costs.
UTILIZES
THE EXISTING LIQUID LINE AS THE HOT GAS PIPE
Eliminates field installation of extra hot gas pipe between condensing
unit and evaporator resulting in simpler design and reduced installation
cost.
FACTORY
INSTALLED DEFROST TERMINATION AND FAN DELAY PRESSURE CONTROLS
Provides shorter defrost periods and faster return to refrigeration
cycle. Eliminates thermal lag (time delay) as found with conventional
thermostat controls. Eliminates wiring the evaporator defrost
controls back to the condensing unit, reducing installation costs.
PRE-HEATED
EVAPORATOR DRAIN PAN
Drain pan heater is energized two minutes prior to start of defrost
cycle. This ensures all water from melting frost is kept warm
throughout the drain line, preventing line blockage.
Allows hot
gas to directly enter the evaporator coil to maximize the heat
transfer effect.
MAXIMUM
COMPRESSOR PROTECTION
Crankcase pressure regulator protects compressor from excessive
suction pressures reducing motor overloads. Two suction accumulators
(one with a liquid/suction heat exchanger) provide maximum heat
transfer and liquid trapping capability during both the defrost
and refrigeration cycle.
