The ACT ES ENERGY SAVING range of dryers was designed to reduce energy consumption. It originates from the ACT range and shares the same construction philosophy and main features. The ACT ES range uses the principle of direct expansion applied to the ALU-DRY exchanger thermal mass. This allows the compressor to switch off when the dryer’s thermal demand is met by the cold mass of the aluminium module and the refrigerant evaporation accumulated in the evaporator. With the machine’s sensors, the electronic controller can manage the compressor and fan on/off cycles, optimising performance and limiting energy consumption, depending on the dryer’s working conditions. To achieve energy savings, the range is equipped with a standard capacitive condensate drain which prevents the expulsion of compressed air together with condensed water. Dedicated selection software calculates energy savings compared to the standard version.
The graph compares the consumption of the ACT ES dryers to the ACT standard model, at the different load conditions.
