Dolomite, as the only dryer on the market, ensures control over the pressure dew point by changing the speed of the cooling fan, controlled by a microprocessor unit. Thanks to this solution, components such as the hot gas by-pass valve and the pressure switch are eliminated. As soon as the ambient temperature drops below 15°C, the refrigerant compressor is automatically switched off to prevent the dryer from freezing. The control panel offers a wide range of parameters and alarms - low temperature, high temperature, probe failure, alarm history, etc. The new heat exchangers are designed in the OMI laboratories and guarantee the highest level of performance with minimal pressure losses.
