RECEIVING AND INSPECTION

1. The dryer cannot be tilted on its side or upside down during shipping.

2. Use forklift from the bottom of the dryer when installing or moving.

3. Dryers are shipped F.O.B. factory. Immediately upon arrival check the dryer for possible

damage. If damage is found, report it to the carrier and ﬁle a damage claim.

4. Check dryer data label to be sure you have the right dryer. Check the data labels voltage and

amperage to be sure it is correct and the one you ordered.

5. Check the refrigeration gauges for pressure. If gauges read 0 PSIG STOP. Do not start dryer. Call

your distributor for service. This could mean there is a leak and the refrigerant has leaked out.

HOW THE AIR DRYER WORKS

MHT Series refrigerated compressed air dryers use refrigeration cooling to condense entrained

moisture out of the compressed air stream. Warm saturated air enters the air-to-air heat exchanger

at the dryer inlet. (1)

In the air –to- air heat exchanger the inlet air is pre-cooled by the outgoing cold air. The

pre-cooled air then enters the air to refrigerant heat exchanger (3) were it is cooled to its lowest

point by the refrigeration in the evaporator. As the air is cooled moisture in the air changes from

a vapor to a liquid. The liquid condensate is removed from the airstream by the separator (4)

and discharged from the dryer by the automatic drain valve. (5) The cold air is reheated by

incoming warm air as it passes back through the air-to-air heat exchanger. Pre-cooling the inlet

air reduces the heat load on the refrigerant compressor, permitting the use of a smaller refrigerant

compressor. (2) The out going cold air is reheated by the in coming hot air. As a result the outlet

air is warmed up as it leaves the dryer. This prevents the outlet pipe from sweating. The air exits

the dryer and is now clean and dry, ready for use.
