PF10 - Model ETV Series - Single Effect Evaporators with Heat Pump
From Vacuum Evaporators and Concentration Units
The ETV model is a vacuum evaporator/concentrator with heat exchanger submerged in the fluid to be processed or, on customer’s demand, with an outer shell and tubes exchanger. Moreover, PF10 is the sole manufacturer of exchanger with submerged plates. All PF10 evaporation plants can be manufactured in AISI 316 (std. version), duplex, super duplex, according to the characteristics of the fluid to be treated.

Product Details
What is vacuum evaporation?
The vacuum evaporation is the passage of state from liquid to gas that occurs at a temperature lower than boiling point of atmospheric pressure.
This technique, that grants energy saving, is used to separate an involatile element from a solution, by obtaining deionized water and a concentrate.
Vacuum evaporation plants are used for the concentration of thermolabile solutions or for the treatment of waste water produced by industries during the different stages of the process.
The recovery of important raw materials from waste water, the reduction of disposal costs and the development of ZLD (Zero Liquid Discharge) plants are the main advantages of the vacuum evaporation.
Features:
All PF10 vacuum evaporators have the following features:
- Automatic operation.
- Discharge of the concentrate is controlled through an electronic timer, set up by the customer, or through a densimeter, without stopping the operation and without loss of vacuum.
- Possibility of recycling the processed fluid
- Automatic antifoam system.
- Sightglass (with cleaning system) to control the contents of the tank.
- Chance of taking samples of the distillate and concentrate without deactivation of the plant.
Advantages
The advantages of vacuum evaporation
The use of the vacuum evaporation technique has shown several advantages among different industrial fields.
For instance, it is possible to reduce 95% of disposal costs and to recycle diluted raw materials, like mineral salt, during the processes of thermal treatment of metals, or galvanic baths from chrome, nickel and copper washings. It is also possible to concentrate substances of pharmaceutical synthesis, food stocks and essences.
The application of the vacuum evaporation technique on ecological platforms grants the treatment of a wide range of waste fluids, also high polluting ones, that cannot normally be treated with the usual purification techniques, like the biological and chemical ones.
The aim is to produce evaporators with the following features:
- low energy consumption
- high quality of the distillate that can be recycled or used as discharge water
- obtain highly concentrated substances
- work atomatically without supervision
- easy maintenance
- integration with already existing systems
- complementary with other process
- allow the development of ZLD
- corrosion-resistant
- low temperature evaporation
