Atrotech understands the importance of quality air and is keen to select the best equipment from the well known manufacturers.

While compressed air from the compressors carries a lot of water vapor and even bulk water, pneumatic tools and machinery require dry air and this in turn calls for dryers to install.

We currently offer Mikropor dryers and downstream equipment well-known for their quality.

  • Low pressure drop
  • On the spot start and operation
  • Less power consumption, thanks to dedicated design for each model
  • R134a refrigerant is standard on all models
  • A state-of-the-art heat exchanger (air-to-air and air to refrigerant) provides for the high performance and energy cost
  • Pressure switch operated cooling fans cut in and out when needed and save energy 
  • Inlet and outlet micro filters fitted as standard scope, actually convert our dryers into an air treatment package delivering class 1.4.1 as per ISO 8573.1 

The MKE Series Refrigerant Circuit and Insulation

Our MKE dryers use environmentally friendly R134a refrigerant suitable for both low and high temperature applications. R-134a has excellent thermodynamic properties and can operate at very low pressure compared to other refrigerants., thus increasing the refrigerant compressor’s service life.

Filled with R-134a, our dryers can operate at very high ambient temperatures. The so called “no loss insulation” adds to the performance of the dryer.

Our end users could expect a constant pressure dew point almost at any condition.


  Digi-Pro Digital Controller

​With the Digi-Pro series controllers, air dryers have outstanding technology for both functionality and dynamism, as well as appearance. New controller design offers users the possibility of making adjustments with one finger, thus easier accessibility. The touch keys have taken the design and dynamism to a top level of technology. The multi-functional display provides an accurate digital dew point display as well as coded alarm monitoring of the refrigerant dryer. Digital controller with embedded features.

  • Digital dew point monitoring
  • Energy-saving mode display
  • Periodic maintenance interval display
  • Status report
  • Hours run meter
  • Fahrenheit and Centigrade selection

  Compact Design

Our dryers are highly reliable, efficient, have a small footprint and lower running cost. Having two filters integrated into the dryer frame offers a huge advantage to the service technicians and end users. The integrated filters save labor time, piping cost and space at the facilities where the Mikropor Dryer is used. The compact size also offers flexibility and economy during their transport.


   Aluminium Plate Heat Exchanger is Standard

  • Very low pressure drop
  • Thin aluminium plate thickness
  • High heat transfer surface area
  • Strong due to external thick cylindrical wall
  • Water separator is optimized for best performance

   ​Zero Clearance Compressed Air Filters with High Performance Elements

Compressed Air Filter kit is standard on tour Mikropor Dryers. Filters with X Element (coalescing filter for water removal) are used for up to 1 micron particles, and those with Y Element (coalescing filter for oil removal) are intended to remove oil content down to 0.01 ppm.

Zero clearance design helps service technicians replace the element in minutes.

Our Mikropor Refrigerated Air Dryers are designed with the feedback from our end users and service technicians in mind.

Our Mikropor dryers are fitted with two elements, two automatic drains and two viton o-rings which help the customers operate the dryer at its best performance until the next planned maintenance. Replacing drains on the filters is critical when replacing elements because drains will get clogged with dirt and oil over time.

   Grooved Couplings and Fittings / Excessive Water Droplet Drains

  • On compressed air lines, grooved couplings and fittings are commonly used in the industry. These couplings increase flexibility on connections, help the service technician dismantle and assemble pipes easily and quickly.
  • Liquid water droplets coming from the line to the inlet of the dryer are separated by the inlet filter and drained. Filter auto drains have manual valves on them. This allows the system to be depressurized when these filters go to service.


Note: Water condenser is available between models MKE-623 and MKE-12500

Correction Factor for MKE Air Dryers

Example for Choosing the Correct Dryer:

If a compressor delivers 200 m³/h at 6 bar, the dryer inlet temperature is 40 °C and ambient temperature is 30 °C
Please choose your Dryer as follows:
200 / 0.94 / 0.92 / 0.98 = 236 m³/h
The correct dryer for this application is MKE305
