Sanpar microfilters in association with hiross spa, italy, brings to india the state-of-the-art refrigerated compressed air dryer-drystar which includes refrigerated compressed air dryer. This new generation drier offers has the specifications like: flow rate: 200 cfm to 3,000 cfm; operating pressure:i bar to 16 bar; operating temperature: 10°c to 50°c; refrigerant r-22 or eco-friendly r407c/ r134a; supply: 400 v/3 ph/50 hz; constant pressure dewpoint of +3°c, with guaranteed residual water vapour content of not more than 0.75 gr/nm3; and dry air rh brought down to less than 15 %. These dryers are microprocessor controlled with temperature sensors for inlet air, outlet air, ambient air, dewpoint, gas suction, gas discharge and condensing temperature, and pressure sensors for gas suction, gas discharge, high and low pressure.The advantages includes fully hermetically sealed compressor, lower power consumption etc. This results in: predictive maintenance, lowest power consumption, and constant dewpoint with varying compressed air heat load depending on the plant air consumption. Special condensers using aisi 316 plate heat exchangers are watercooled. These dryers are direct expansion type with tube-in-tube evaporator and need no foundation. Their noise level is less than 60 db.
