CONTINUOUSLY ADJUSTABLE. TWO SERIES, ONE GOAL. AERZEN finds the right compressor solution for your application. The seamless overlap between performance ranges gives you maximum flexibility in volume sizes and optimal machine utilisation. With two series featuring a water or air-cooled design (W = water-coolded, A = air-cooled) and an individual performance capacity and size, AERZEN offers you maximal plant performance. Because it has a higher power requirement, the two-stage screw compressor offers energy advantages; thanks to the overlap areas, there is no need to switch to the next size. This ensures optimal use of space and a faster return on investment. The water-cooled design makes heat recovery possible, for an even better energy balance.
