Stable dew point at all operating conditions

AC 2650-8500 FS/VSD is Pneumatech’s premium refrigeration dryer range at higher flows: from 4500 up to 14400 m³/h (2650-8475 cfm). AC 2650-8500 (VSD) refrigerant dryers are engineered in house and tested using the most stringent methods (at ambient temperatures up to 46°C/115°F). They exceed the international standards for compressed air purity and are tested according to ISO 7183:2007.

New AC Range is the most efficient compressed air dryer for continuous and varying air demand applications. A combination of new innovative technologies integrated in the new AC 2650-8500 (VSD) dryers’ design makes them a perfect match for customers looking for reliable equipment with a low cost of ownership. The unique combination of high efficiency components, a smart unit design and an advanced unit control system gives an opportunity to save on average 50% of the consumed energy.

Significantly reduced power consumption and low quantities of refrigerant make sure the AC 2650-8500 (VSD) dryers operate at the lowest possible carbon footprint.
