EMD Series from Van Air Systems Inc. is suitable for manufacturing applications requiring dry, compressed air. Controller regulates an unloader to allow the refrigeration compressor to run under low flow conditions using less energy than traditional designs. Dewpoint temperature measurement from the evaporator outlet air stream to the microprocessor ensures consistent performance without dewpoint spikes common to thermal mass systems. Eliminating thermal mass increases cooling efficiency. Features include a digital dewpoint readout and electric drain with panel-mounted controls.
