C&G Depurazione Industriale S.r.l.

- Model VN-T Series - Vacuum Wastewater Evaporators



The V-NT series of vacuum evaporators have vertical development with the boiling chamber in the lower part and the condensation chamber in the upper part. The vacuum system guarantees minimum energy expenditure. The distance between the free surface of the effluent being treated and the collection plate guarantees the absence of drag out. and therefore a higher purity in the distillate.


C&G Depurazione Industriale Sri has been operating since 1971 in the industrial wastewater treatment sector. The Know-how acquired from the design and construction of over 3000 plants, sold both in Italy and abroad, encourages our constant growth, research and innovation, and allows us to propose a complete and personalised service to our customers.

Countries where the C&G logo is already well known and appreciated are: Italy. France. Belgium. Spain. Holland. Slovakia. Slovenia. Poland. Turkey. Greece. Russia. Lebanon. UAE. USA. Mexico. Taiwan, China. India. Indonesia. Malaysia. Japan. Brazil and others.

Refrigerant circuit

The V-NT evaporator series are plants which use a heat-pump. There is a refrigerant circuit where high pressure is used to yield heat to the wastewater and bring it to boil and low pressure is used to re-condense the distillate produced by removing the heat.

Vacuum circuit

A vacuum is created within the boiling chamber through the use of a liquid ring vacuum pump and an ejector.
This extraction system guarantees a residual pressure of 33 nibar inside the evaporator.

Distillate circuit

The discharge of the distillate is independent. There is an accumulation tank placed on the skid which is continuously discharged using an apposite centrifuge pump.

Concentrate discharge

The concentrate produced is discharged using an apposite pump that not only allows the discharge to occur, but also permits a continuous recycling of the concentrate, guaranteeing better uniformity and an increase in the thermal exchange coefficient.

Automation, alarms and control

C&G evaporators can work unattended and continuously 24/24 hours thanks to control through PLC. The use of simple, logical software allows easy control and immediate set up of the working parameters. The use of a synoptic (standard from model V-NT 1000 up) guarantees a rapid and intuitive global control of the working of the machine.
