Compressed Air
Dryers

Moisture in compressed air causes corrosion, production downtime and quality losses. The BOGE dryer range covers every requirement — from standard refrigerant drying to pressure dew points of −70°C, breathing air and point-of-use membrane drying.

Refrigerant Dryers Adsorption Dryers Dew points to −70°C Breathing Air Approved Membrane Drying
Complete Dryer Range

Refrigerant, adsorption
& specialist — every dew point covered

BOGE dryers ensure a consistently dry and reliable compressed air supply, protecting systems, tools, and end products in the long term. Select the right technology for your required dew point, pressure and flow rate.

Selection Guide

Which dryer for
which dew point?

The required pressure dew point is the primary selection criterion for a compressed air dryer. Lower dew points require more energy-intensive technology. Contact Tranco Tech for a recommendation matched to your application, flow rate and pressure.
