Sanpar microfilters pvt. Ltd., in association with hiross spa, italy, supplies offers large capacity dryers. Their key features and specifications of large capacity dryers are: flow rates from 2,000 cfm to 17,000 cfm; operating pressures from 1 to 12 bar; operating temperatures from 10°c to 50°c; refrigerant is r-22 or eco-friendly r407c/ r134a; low power consumption using 400 v/3 -ph/50 hz supply; constant pressure dew-point of +3°c with guaranteed residual water vapour content of not more than 0.75 gr/ nm3 ,dry air rh brought down to less than 15%; and semi-hermetically sealed compressor. These large capacity dryers are microprocessor controlled with temperature sensors for inlet air, outlet air, ambient air, dew-point, gas suction, gas discharge and condensing temperature; and pressure sensors for gas suction, gas discharge, high and low pressure which leads to . This results in: predictive maintenance; low power consumption; and constant dew-point with varying compressed air heat load depending on the plant air consumption.
