Reliable refrigeration dryers with variable speed technology, which match energy consumption to the actual compressed air demand
Pneumatech extends its premium AC refrigerated dryer range with variable speed technology in order to match the energy consumption to the actual compressed air demand.
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.
