Refrigerated Compressed Air Dryer, 1.5–90 Nm³/min

Refrigerated dryer that removes moisture from compressed air downstream of the compressor. The standard FC version handles air up to 45 °C, the high-temperature HFC version up to 80 °C. 17 sizes from 1.5 to 90 Nm³/min.

Key features

• pressure dew point +2…+10 °C;
• copper-finned condenser for high heat transfer and subcooling;
• high-efficiency refrigeration compressors;
• timed electronic drain with anti-clogging protection;
• HFC version for hot air up to 80 °C.

Use in plastics production

• air drying for the pneumatics of injection and blow molding machines;
• protection of pellet conveying from condensate;
• air preparation upstream of line filters;
• installation after a compressor without aftercooler (HFC).

Technical specifications

Models

Values separated by a slash refer to the FC / HFC versions. Power supply: 220 V 50/60 Hz single-phase for smaller models; 380 V 50 Hz three-phase for larger models.

Operating conditions: pressure 0.4–1.0 MPa, ambient temperature +2…+40 °C, inlet air temperature +5…+45 °C (FC) or +5…+80 °C (HFC).

How to select

Dryer capacity must be at least equal to compressor capacity. With a high compressor room temperature apply a correction and choose a larger size.

Questions and answers

How do FC and HFC differ?

FC handles air up to 45 °C, HFC up to 80 °C; HFC can be installed directly after the compressor without an aftercooler.

Is a filter needed before the dryer?

Yes, an AO pre-filter protects the heat exchanger from oil and particles.
