CompAir AX4M -40°C Modular desiccant dryer

Description CompAir AX4M -40°C Modular desiccant dryer

A compact Modular desiccant dryer with a microprocessor for low-capacity compressed air systems. Provides deep air drying down to a -40°C dew point, preventing corrosion, condensate freezing, pneumatic system damage, and microorganism growth. Used in the chemical, food, pharmaceutical, automotive, and oil & gas processing industries.

Technical specifications of AXM:

• Capacity: 0.08-5 m³/min
• Dew point: -40°C and optionally -70°C
• Operating pressure: max. 14 bar
• Power supply: 230 V / 1 phase / 50–60 Hz
• Regeneration type: heatless (PSA)
• Control: basic microcontroller with cycle indication

The dryers use a heatless PSA method for regenerating the adsorbent material. The design does not heat up and minimizes maintenance costs.

PSA desiccant dryer are the simplest type of desiccant dryers and have long been the best choice for many industries and applications. They are simple, reliable, and cost-effective solutions for small and medium flow systems, often the only available working technology. Additionally, the modular desiccant dryer is a reliable, compact, and lightweight drying device that can be installed both in a compressor room and at the point of use.

Key advantages of AXM:

✅ High air quality: ISO Class 2 and optionally Class 1
✅ Reduced ownership cost thanks to a design that processes only the required amount of air
✅ Easy to use
✅ Compact design for space-saving installation
✅ High efficiency with low air consumption
✅ Low noise level, less than 75 dB
✅ Easy maintenance and operation
✅ Supplied with pre- and post-filters
✅ Cycle time indication
✅ Drying/regeneration indication for right/left tower

The dryer has a compact design for optimized installation with air inlet and outlet ports located at the rear of the unit, and connecting pipes can be positioned on either the right or left side. 

Desiccant dryer operating technology

Desiccant dryers work on the principle of moisture always migrating to the driest medium possible. Therefore,water vapour is removed from compressed air by passing it over an adsorbent desiccant material.

As the air contacts the adsorbent material, water vapourtransfers from the wet air to the dry desiccant, however,adsorbent materials have a fixed adsorption capacity and once this capacity is reached, they must be regeneratedor replaced. Therefore, to provide a continuous supply of clean, dry compressed air, adsorbent dryers utilise two chambers of desiccant material and 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-pressurised, ready to come on-line. All desiccant dryers remove water in this manner.
