Heat pump evaporator with forced circulation and external shell and tube heat exchanger.
Designed to produce the best distillate quality with minimum capital and operating costs
PC F series evaporators have to be connected to an electric power supply and to have highly available cooling air, like all heat pump equipment.
Each model in the PC F series is a compact module that can be handled and connected to the utilities simply and easily, by means of standard connections.
All the models of the PC F series are controlled by a PLC that controls the functioning of the evaporator, including water-to-be-treated feeding and evaporation products discharge. All models have a wide range of sensors that enable the PLC to manage the evaporator automatically, even in a critical situation. This assures long life for the components and very high quality products (distillate and concentrate). All models are designed to function continuously, 24/7, with minimum supervision.
PC F series evaporators operate in high vacuum conditions to recover a large part of the thermal energy produced by the heat pump. The pressure in the boiling chamber is set at 5-6 kPa (absolute), so that the boiling temperature of the water is around 35°C, much lower than that at atmospheric pressure.
Under these conditions the phenomena that may reduce performance are either prevented or slowed down. Such phenomena are:
- evaporation of undesired substances.
The forced circulation circuit plus the shell and tube heat exchanger differentiate EVALED® PC F series.
The advantages of the PC F series evaporators are:
- superior distillate quality
- reduction of finishing and post treatment
- high thermal efficiency
- low power consumption
- shutdowns reduction
- cleaning and maintenance reduction
- longer operation life.
PC F series evaporators are particularly suitable for:
- Mechanical industry
- Aluminum die-casting
- Landfills and waste disposal
- Graphic arts
- Galvanic industry and surface treatments
- Food & beverage
- Chemical industry
