3. System Design
The SRC dryer consists of three circuits from right to left: The Air Circuit, the Coolant Circuit, and the
Refrigeration Circuit:

The Air Circuit:
Consisting primarily of:
A. Air-to-Air heat Exchanger,
B. Air-to-Coolant Heat Exchanger,
C. Slowflow Demister Separator, and
D. Condensate Chamber
The air enters the dryer and passes through the Air-to-Air Heat Exchanger (A) where it is
cooled by the outgoing air. The air then passes through the Air-to-Coolant Heat Exchanger (B)
where it is further cooled by the coolant. The air then passes through the Slowflow Demister
Separator (C) where the condensate is separated from the air. The condensate collects in the
Condensate Chamber (D), before being discharged from the system by a condensate drain
(not shown). The air passes back through the Air-to-Air Heat Exchanger where it is reheated
by the incoming air before leaving the dryer.
•
The Coolant Circuit
: Consisting primarily of:
B. Air-to-Coolant Heat Exchanger,
E. Coolant-to-Refrigerant Heat Exchanger, and
F. Coolant Re-circulation Pump.
The coolant passes through the Air-to-Coolant Heat Exchanger (B) where it absorbs heat from
the air. It then passes through the Coolant-to-Refrigerant Heat Exchanger where it is cooled
by the refrigerant, and flows into the Coolant Tank. It is re-circulated continuously by the
Coolant Re-circulation Pump (F).
