8、EVALED? PC Tech nical ReportsEVALED PCEVALED? E SeriesE series is designed to produce maximum distillate quality with minimum capital and operating costs. Each model is a compact skid-m oun ted un it, simple, safe and easy to move. Con trol is by a PLC, including the functions of feed and discharge,
9、 therefore allowing automatic operation and minimum supervisi on. All models are desig ned for continu ous operati on, 24hs/day, and require just an electrical supply and compressed air.E series evaporators operate in a high vacuum condition, with the boiling chamber pressure set at 5-6 kPa (absolut
10、e), in order to save the thermal energy produced by the heat pump. In this way the boiling temperature of the waste water is approximately 40 C (104 F) and typical phenomena(scali ng, precipitati on, corrosi on) which may reduce the performa nee are either elim in ated or much reduced.E evaporators
