Refrigerant Air Dryers
Refrigerant air dryers are among the most common types of air dryers due to their ease of maintenance and their cost effectiveness. They’re highly suitable for air-drying applications where a pressure dew point of +3 °C is the lowest achievable.
Desiccant Air Dryers
Desiccant air dryers work on the principle of pressure swing adsorption (PSA). To provide a continuous supply of clean, dry compressed air, desiccant dryers utilize two towers/receivers filled with desiccant material. Desiccant air dryers provide pressure dew point down to -70 °.
Membrane air dryers
TMC membrane compressed air dryers are characterized by their compact design and low purge-air requirement. They are easy to install and maintenance free. No external power is needed. Suitable for pressure dew point down to -40 °.
TMC delivers a complete program of filtration and separation products for compressed air systems. Compressed air filters remove oil and different contaminants from the compressed air, while air dryers of various kinds remove water vapor.
All TMC Air Dryers and Filters are designed and built for optimal performance in the actual given operating temperatures and conditions. TMC can design and deliver complete solutions made to individual customer requirements.

TMC guarantees high quality, reliability and energy efficient operation. By installing a correctly calculated and sized air treatment system, consisting of air filters and air dryers, you will maximize the lifetime of your air operated equipment and keep maintenance costs at a minimum.
TMC delivers products to match every air quality class listed in the ISO8573-1:2010 standard.
Refrigerant Air Dryers – Preventing Vapor
The purpose of air dryers is to prevent vapor from forming within the pipe system. Refrigerant air dryers are among the most common types of air dryers due to their ease of maintenance and their cost-effectiveness. They’re highly suitable for air-drying applications where a pressure dew point of + 3 degrees C is the lowest achievable.
Once the compressed air is cooled and water is removed, the air is reheated to approximately ambient temperature. This ensures no more vapor forms within the pipe system.
TMC refrigerant air dryers are equipped with a hot gas bypass control, which ensures a constant dew point even under different load conditions. Both air-cooled and water-cooled air dryer versions are available.
Technical highlights:
- Constant dewpoint – Hot gas bypass control
- Scroll compressor – Low noise & vibration in operation
- Aluminum heat exchanger – no corrosion
- Compact and space saving
Desiccant Air Dryers
Desiccant air dryers work on the principle of moisture always migrating to the driest medium possible. Therefore, water vapor is removed from compressed air by passing it over a bed of adsorbent desiccant material. When the air gets in contact with the adsorbent material, water vapor transfers from the wet air to the dry desiccant.
However, adsorbent materials have a fixed adsorption capacity. Once this capacity is reached, they must be regenerated or replaced. Therefore, to provide a continuous supply of clean, dry compressed air, adsorbent dryers utilize two towers/receivers of desiccant material. At any one time, whilst one chamber is on-line, drying the incoming compressed air, the other is either off-line, being regenerated or is re-pressurized, ready to come on-line.
There are two types of desiccant air dryers: Heatless and Heated. The most common is the heatless type, especially for marine and offshore applications where high ambient temperatures is a challenge.
Technical highlights:
- Dewpoint controlled operation
- Intermittent operations
- Saving purge air & energy when compressor not running or in offload
- Dewpoint sensor with 4-20 mA and Modbus
- Utilization of all desiccants
- Pre & after filter in ultra-pleat design which are more flexible against pressure peaks. Pleated filter had low pressure drop and larger surface.
- Robust shuttle valve & solenoid valve
- Service-friendly dryer
