Features & Benefits

UNIQUE HEAT EXCHANGER:
vertical profile allows for minimum pressure drop and self cleans using gravitational force

MAXIMUM DEW POINT STABILITY:
the independent operation of the controller provides variable compressor and fan operation for an ultra stable dew point with a no-freeze-up guarantee

INTEGRATED iMAT®:
reliable condensate discharge and maximum energy savings

MAINTENANCE FRIENDLY:
the entire range features an open frame that provides easy access to all components

VARIABLE SPEED TECHNOLOGY:
maximized energy savings with unique variable speed compressor and fan, and high end controller

iDRY® iVSD

Warm compressed air, saturated with water vapor, is precooled in the air/air heat exchanger (1) when entering the refrigeration dryer. Because demand on a compressed air system is often varied, the iDRY® iVSD intelligent controller monitors the incoming conditions and adjusts the compressor and condenser fan speed (2a) to meet the required cooling capacity of the refrigerant in the downstream air/refrigerant heat exchanger (2b). This action thereby saves energy when low conditions are reached, and over the life of the dryer operating costs decrease. The gravitational force sustains a particularly high droplet separation of nearly 99%. In the very large condensate collection chamber with subsequent recirculation, the flow velocity is significantly reduced. Re-entrainment of already separated droplets is reliably prevented in this manner (3). The accumulated condensate is discharged from the iDRY® via the level-controlled iMAT® condensate drain avoiding any compressed air losses. (4). Prior to leaving the iDRY®, the dried and cold compressed air is reheated in the air/air heat exchanger. Through this process, the relative air humidity is significantly reduced and the cooling capacity employed is recovered by up to 60%.
