FRIULAIR has increased it’s range of compressed air dryers with the introduction of the new ACT range (Aluminium Cooling Technologies). This high efficiently cooling module has a direct effect on reducing energy consumption and pressure drop. The main advantages are: low pressure drop even with load variances and a constant pressure DewPoint with differing load conditions. The components of the ACT range from refrigerant to materials of construction have been selected with maximum respect for the environment and their ability to be recycled.

Operation of the dryer is monitored by a digital thermometer in the control panel. The DMC20 electronic controller is fitted as standard to models ACT 900 - 1800 and as an option to models ACT 180 - 600. The precise and accurate hot gas by-pass valve, which prevents the formation of ice inside the evaporator at any load condition, is a recent development unavailable in the past. The valve is set during final test and no further adjustments are necessary. There is only one model of valve for each refrigerant used. All models are fitted with a timed electronic drain. Discharge and pause times are adjustable. A zero loss drain is available as an option. Generous sizing of the condenser ensures maximum performance of the refrigerant circuit and the ability to operate with changes in ambient conditions. Access to the condenser for cleaning and maintenance is straightforward. ALU-DRY Module A The air-to-air and the air-to-refrigerant heat exchangers plus the "demister" type condensate separator are housed in an unique module. B The counter flows of compressed air in the air-to-air heat exchanger ensure maximum heat transfer. C The generous dimensions of the air-to-refrigerant heat exchanger plus the counter flow gas streams allow full and complete evaporation of the refrigerant (preventing liquid returning to the compressor).     D The high efficiency condensate separator is located within the heat exchanger module. No maintenance is required and the coalescing effect results in a high degree of moisture separation.     E The large capacity separator is designed to hold condensate also at high humidity in compressed inlet air. F The large cross section of flow channels within the heat exchanger module leads to low velocities and reduced power requirements. G It is mandatory to install a filter (with filtration grade at least 5 micron) on the dryer inlet side to prevent that rust, scale or other pollutants could clog the Alu-Dry Module and the condensate drain.
