2.2 AIR SYSTEM Reference Name Evaporator Condensate separator Condensate drain Heat exchanger Dew point indicator Description Compressed air enters heat exchanger (10) and is cooled by the outgoing, cold, dried air. Water in the incoming air starts to condense. The air then flows through heat exchanger/evaporator (10 &... -

2.3 REFRIGERATION SYSTEM Reference Name Refrigerant compressor Condenser Evaporator Capillary tube filter Liquid separator High pressure switch Hot gas by-pass valve Description Compressor (1) delivers hot, high-pressure refrigerant gas which flows through condenser (2) where most of the refrigerant condenses. The liquid flows through liquid refrigerant dryer/filter (8) to capillary tube (7). -
Page 10: Automatic Regulation System
2.4 AUTOMATIC REGULATION SYSTEM Reference Name Refrigerant compressor Motor fan Liquid separator High pressure switch Hot gas by-pass valve Description The condenser pressure must be kept as constant as possible to obtain stable operation. Fan control switch therefore stops and starts the cooling fan (3). If, under partial or no load, the evaporator pressure drops below a certain level, the hot gas by-pass valve (9) opens and hot, high-pressure gas is fed to the evaporator circuit to prevent the evaporator pressure from dropping any further. -
Page 11: Condensate Drain System
2.5 CONDENSATE DRAIN SYSTEM Description The dryers are equipped with an electronic water drain (EWD). The condensate from the condensate trap accumulates in a collector. On preset time intervals, the condensate is discharged through the drain outlet. The opening time is limited to 1 second, which limits compressed air waste to a minimum. - Page 12 Setting： 1. Switch on the power. Note: the voltage must comply with the voltage mentioned on the coil. 2. It will start with its pre-set time setting of 0.5 min OFF and 1 sec ON time. 3. You can change the pre-set values to anything ranging from 0.5-10 sec and 0.5-5 Min. 4.

Page 14: Examples Of Installation
2.1 EXAMPLES OF INSTALLATION This can be used when the compressor runs constantly and the cooling capacity of the dryer is equal to the air delivery of the compressor. Under this condition the load of the dryer is constant. This can be used when the air demand is variable. The air demand is for short periods higher than the compressor can deliver, the air receiver must be large enough to meet the instant air demand. - Page 15 Reference Description Compressor Air receiver Install pre-filters and post-filters Provide an air inlet valve and outlet valve. If a bypass pipe and valve are installed, the dryer and filters can be serviced while by-passing the dryer Dryer Main air line...

Page 19: Starting
4.4 STARTING Attention To ensure optimum operational efficiency, do not use dryer on/off switch repeatedly within a short time period. Wait at least 5 minutes to start the dryer again after stopping to allow pressure equalization. To keep the compressed air net free of condensate, start the dryer before starting the compressor and stop the compressor before stopping the dryer. -
