AC 650-2100 VSD Cycling Dryers

Reliable refrigeration dryers with variable speed technology, which match energy consumption to the actual compressed air demand

Contact your local expert

Premium energy efficiency

The Variable Speed Drive (VSD) matches the energy consumption to the actual air demand, hereby reducing energy costs up to 70%, compared to traditional dryers.

Stable pressure dew point

The variable speed drive reduces the speed of the refrigerant compressor, hereby ensuring a stable dew point at all times.

Purelogic Controller

The Purelogic ensures maximum reliability by monitoring the most important parameters of the dryer and offers impressive control and monitoring capabilities, like internet-based visualization.

Rotary compressors & R410A

The range is equipped with rotary compressors and R410A refrigerant. This combination is up to 30% more energy efficient; requires 19% less refrigerant charge and is 100% compliant to future European legislation

Superior performance & reliability

The refrigeration cycle is optimized in all conditions thanks to the use of automatic expansion valves and electronic hot gas bypass valves.

Availability of water-cooled condensers

The AC650-2100 VSD range is available with both air-cooled and water-cooled condensers.

Compressed air refrigerant dryer for superior performance and reliability

AC 650-2100 is Pneumatech’s premium refrigeration dryer range at higher flows: from 1120 up to 3636 m³/hr (657-2141 cfm).

As in the small AC range, operating costs are significantly reduced thanks to the energy saving and flow switch algorithms, the zero-loss drains, the low pressure drop over the heat exchangers and the combination of rotary compressors and R410A refrigerant. The refrigeration cycle is further optimized in all working conditions by making use of the automatic expansion valve & electronic hot gas bypass valve.

From AC 650 onwards, dedicated variable speed (VSD) variants have been added to the range. The VSD controller incorporated in these dryers matches the energy consumption to the actual compressed air demand. This reduces energy used by as much as 70%, compared to conventional dryers. It works by varying the speed of the compressor, hereby ensuring a stable dew point.

The PurelogicTM is installed as standard on all dryers: it ensures maximum reliability by monitoring the most important parameters of the dryer and offers impressive control and monitoring capabilities, like internet-based visualization. The entire range is available in both air-cooled and water-cooled versions.
