Refrigerated Air Dryer 3/4″ 37KW (IDFA37E-23-K)

Refrigerated Air Dryer 3/4″ 37KW (IDFA37E-23-K)


A compressed air dryer is a device for removing water vapor from compressed air.

Excessive water in compressed air can cause a variety of operational problems for users of compressed air. These include freezing of outdoor air lines, corrosion in piping and equipment, malfunctioning of pneumatic process control instruments, fouling of processes and products, and more.

The IDFA range of air dryers is an extremely effective method of removing this water and avoiding related issues.

The all new IDFA Air Dryer range is 30% smaller in size, and 40% lighter than the predecessor range.

 A refrigerated air dryer is a device for removing water vapor from compressed air.

Cooling ratings of 3-75kW can be attained using the IDFA refrigerated air dryer. The all new IDFA range is 30% smaller in size, and 40% lighter than its predecessor. An increased air flow capacity of 40% is provided based on previous models. Energy saving benefits are attained through the use of a stainless steel heat-exchanger.

The use of electric power is unnecessary in order to power the IDG membrane dryer, this reduces energy costs and is compatible with dew point as low as -60°C.

Dry air can be provided at dew points as low as -50°C by the dryer, offering flow rates of 100 to 975 l/min. They are constructed without a heater and electric control board making them light weight and compact. The built in indicator makes it easy to check the dew point of the dryer. (Not CE marked).

Operation Principle

Saturated compressed air enters the air-to-air heat exchanger, the incoming air is then precooled by the cold air exiting the dryer. The air then passes through the evaporator, where it is further cooled, to a 3°C dew point. As the air cools, the water condenses from a vapour to a liquid which is removed by the automatic drain.The dry air is then passed back through the air-to-air heat exchanger where it is reheated before leaving the dryer.
