Low Temperature Evaporation V-HP-SF-10000 - High-Efficiency 440 L/h Evaporator from China Suppliers & Factory
Low Temperature Evaporation Technology
Low temperature evaporation refers to the evaporation process with an operating temperature generally between 35 and 40 ° C. The technology mainly deals with a variety of polluted wastewater, water containing oil products and viscous or crystalline fluids, especially from cutting fluid wastewater, cleaning wastewater, surface treatment wastewater, high salt wastewater, high concentration wastewater, inspection wastewater or other production process water.
Basic Principle of Low Temperature Evaporation Technology
Preheating
This step is automatic. After the original bucket reaches the medium level, the pump runs to produce vacuum, the evaporator automatically enters water, and the compressor runs to generate heat to heat the wastewater in the evaporation tank. In the vacuum state, the wastewater temperature rises to about 30℃, and the wastewater begins to evaporate, and the preheating is completed.
Evaporation and Concentration Process
The evaporation temperature is set at 35-40℃, the compressor compresses the refrigerant to generate heat, and the water evaporates rapidly at the same time, the refrigerant absorbs heat and refrigeration after gasification through the expansion valve, and the vapor rises and liquefied into the cold liquid into the water storage tank. The refrigerant absorbs heat, and then compresses and heats the waste water. If bubbles rise during the evaporation process, the sensor detects that the defoamer is automatically added to the defoamer, and after a cycle is completed, the concentrated liquid is discharged (the time of a cycle can be set).
Concentrate Discharge
After the completion of an evaporation cycle, the compression pump stops working, the concentrate pipeline pneumatic valve is opened, the evaporation tank is pressurized, and the concentration hydraulic pressure is put into the concentration barrel.
Liquid Handling
Atomized liquids to achieve maximum evaporation efficiency.

Frequently Asked Questions
What is the operating temperature of low temperature evaporation technology?
The operating temperature of low temperature evaporation is generally kept between 35 and 40 °C.
What types of wastewater are suitable for this treatment?
It is ideal for processing cutting fluid wastewater, cleaning wastewater, surface treatment wastewater, high salt wastewater, high concentration wastewater, inspection wastewater, and other oily, viscous, or crystalline fluids.
How is the preheating process controlled?
The preheating phase is fully automatic. Once the medium level is reached in the original bucket, the pump creates a vacuum, the evaporator takes in water, and the compressor heats the wastewater to approximately 30°C.
What happens if bubbles rise during evaporation?
The system features a sensor that automatically detects bubbles and triggers the addition of defoamer to ensure stable operation.
How is the concentrate discharged from the system?
After the evaporation cycle completes, the compression pump stops, the pneumatic valve opens, the evaporation tank is pressurized, and the concentrated liquid is discharged into the concentration barrel.
How does liquid handling optimize the process?
The liquid is atomized during the handling stage to achieve maximum evaporation efficiency.
