Sizing Information

Example: Select a dryer for 95 scfm airflow at 90 psig

If inlet conditions are different from rating conditions, dryer capacity will be affected as shown in the Dryer Sizing Chart. Inlet air temperature, ambient air temperature, inlet pressure and air flow must be established before a dryer can be specified for your application.

(6.2 barg) inlet pressure, 90˚F (32˚C) inlet air temperature and 80˚F (27˚C) ambient air temperature conditions.

Step 1: On the Dryer Sizing Chart, locate the inlet air temperature, 90˚F (32˚C).

Step 2: At 90˚F (32˚C) inlet air temperature, read across the chart to 90 psig (6.2 barg) inlet air pressure. The correction factor is 1.18.

Step 3: To adjust the required flow for standard rating conditions, divide the required flow by 1.18.

95 scfm/1.18 = 80 scfm Step 4:

Using the ratings and dimensional data, select a dryer which has a rated capacity of 80 scfm or larger. Select Model HX100.

Step 5: Dryer capacity will also be affected if the ambient air temperature is different from 100˚F (38˚C). For accurate dryer sizing, divide the adjusted dryer flow determined in step 3 by the appropriate correction factor from the table. For 80˚F (27˚C) ambient air temperature, required dryer capacity is:

80 scfm/1.12 = 71 scfm From the ratings and dimensional data, select Model HX75.

The HX Heat Exchanger utilizes a Chevron plate angle that provides high heat transfer and low fouling risk. Models HX500-3000

How it Works HX Series dryers use refrigeration cooling to condense entrained moisture out of the air stream. Warm saturated air enters the air-to-air heat exchanger where it is cooled by outgoing cold air. The inlet air is further cooled in the refrigeration chiller. Condensate is removed from the air stream by an automatic drain valve. Models HX7 through HX425 utilize a capillary tube and a hot gas bypass valve (HGBV) that regulates the flow of liquid refrigerant to the chiller, preventing freeze-ups. The HGBV is adjusted at the factory. Operation of the dryer is fully automatic. Models HX500 through HX3000 incorporate a unique design plate type heat exchanger, with a Chevron plate angle that provides high heat transfer and a low fouling risk. The compact, corrosion resistant, stainless steel, plate heat exchanger increases reliability while significantly reducing dryer size and weight. With this heat exchanger design the need for pre-filters is eliminated, providing a great benefit over the competitors’ heat exchanger designs. These models have a thermal expansion valve for precise metering of the refrigerant over a full range of flows. The HGBV works with the thermal expansion valve to prevent freeze-ups from 0-100% of load.
