EVAPO® is a series of low-temperature vacuum evaporators with a submerged heat exchanger and an electric heat pump. Unlike traditional evaporators, which use a horizontal external heat exchanger or a vertical internal heat exchanger, the evaporator eliminates the need for circulating the liquid being evaporated. The evaporation process is conducted under a vacuum of approximately 30-60 mbar and a temperature of approximately 35°C. The vacuum is generated by a vacuum pump. The necessary heat and cooling are supplied by an integrated compressor heat pump. The compressor compresses the refrigerant gas to a temperature of approximately 70°C. This is pumped to a coil located in the evaporator section, where the liquid boils. The concentrate concentration level is determined by time or by measuring the liquid’s density. After the concentration process is complete, the concentrate is automatically discharged by a pump. Wastewater is collected automatically without the use of pumps. The evaporator has no circulation pumps or tubular heat exchangers that could clog. Systems using EVAPO “learn”—maintaining optimal desalination levels or other preset permeate parameters by automatically responding to changing input and output conditions. This maximizes water recovery and ensures the highest efficiency and operational stability of the entire process.
Advantages of the solution:
- A simplified process without pumps and heat exchangers, minimizing the risk of clogging.
- Increased heat exchange efficiency.
- Evaporation at low temperatures (approx. 35°C) reduces energy consumption.
- Provides both heat and cooling, increasing the system’s energy efficiency.
- Concentrate is automatically discharged, and the concentration level is determined by time or density measurement.
- The system “learns” and automatically adjusts parameters (e.g., desalination, permeate quality) to changing conditions.
- Maximizes the amount of water recovered while maintaining process stability.
