Compressed Air Dryers

Companies that utilize high-capacity units, require extremely dry air, or need to separate gases - such as automobile manufacturers, pharmaceutical companies, petrochemical, chemical, oil & gas, and semiconductors, demand special requirements that are not available in standard products. delair® engineers and manufactures refrigerant and adsorption dryers that meet the needs of industry.

Refrigerant dryers
Refrigerant dryers are used in various industries to produce dry, clean instrument and process air. Refrigerant dryers reduce the concentration of water vapor and lower the dew point of the air to approximately 2°C (36°F), removing approximately 80 to 90 percent of the water vapor.

Adsorption dryers
Absorption dryers are the best solution for instrumentation applications, low ambient temperatures during the winter, cold storage or extreme expansion of compressed air where the danger of creating condensate water or even ice has to be avoided. The pressure dew point achieved with a refrigerant dryer would not be low enough. An adsorption dryer removes 99.9 percent of the water vapor from the air, resulting in a pressure dew point of -40°C (-40°F) or less.

Adsorption dryers are used in the beverage industry (CO2 dryers and instrument air), the chemical and petrochemical industries, the automotive industry (coating equipment), and steel factories.
