High Inlet Temperature Refrigerated Air Dryer
23
Problem Probable Cause Remedy
High Refrigeration Circuit
Head Pressure
(compressor is overloaded
and gauge is reading out
of recommended pressure
range). Refrigeration condenser
coil fouled or dirty or air
flow blocked. Clean / blow off condensing coil of dirt or
debris from the inside out. Clear area in front of
condensing coil of any items blocking airflow to
coil.
Condenser fan motor not
working properly or faulty. Check fan motor for proper voltage and amp
draw, repair or replace fan motor.
Defective fan control
switch. Repair switch or replace.
Ambient temperature
too high at refrigeration
dryer location.
Cool ambient temperature around location of
refrigeration dryer down to a maximum of 100°
F or relocate dryer to a different area with lower
ambient temperature.
Compressed air
temperature entering the
refrigeration dryer is
too high. Check compressed air inlet temperature to ensure
it is within the operating parameters listed in the
Design Parameter section. Check air compressor
after cooler for malfunction.
Faulty heat exchanger,
compressed air leaking
into refrigeration circuit. Repair or replace evaporator or heat exchanger
and recharge with refrigerant.
Low Refrigeration
Circuit Head Pressure
(gauge is reading out of
recommended
pressure range). Ambient temperature
too low at refrigeration
dryer location. Increase ambient temperature at refrigeration
dryer location or relocate dryer.
Refrigeration dryer
circuit low on refrigerant. Refrigeration circuit low on refrigerant, locate
leak in refrigeration circuit, repair and recharge
according to specifications.
Refrigeration compressor
not working properly or
faulty. Check refrigeration compressor for proper
voltage and amp draw, repair or replace
refrigeration compressor.
