The vacuum evaporator is made by Italian Ecoteck in year 2003 and operation was stopped in early 2009 and it is in very good operational condition. This unit is made for concentrate acidic liquid wastes and therefore all liquid touching parts are made of acid proof steel ( SS 2353) or PVC. The evaporation capacity of the unit is 5000 liters / day. The unit is a complete working unit and it includes evaporator, boiler, heat pump, centrifugal pump, water-air cooler, steam ejector, control unit and all other necessary equipment to complete the unit.

Operation principle:
Steam rises from the boiler through a drop dispenser to the cooling unit where it condensates. The condensate drops with the gravity down to vacuum system. In-build heat pump heats up the cooling media and simultaneously cools down the condensate. Water – air cooler cools down the extra heat from the process. Necessary vacuum is generated with a centrifugal pump and a steam ejector. Condensate rejection takes place in accordance with prescheduled frequency.
