Propellent  plate evaporator is a highly efficient and energy-saving evaporator. Compared with shell and tube evaporator, it has the following characteristics:

1. High heat exchange efficiency and low capital investment
The special corrugated shape of the evaporator plate makes the fluid produce strong turbulence. Compared with the shell and tube evaporator, the heat transfer coefficient is improved, the minimum temperature difference between the cold and heat medium is smaller, and the heat exchange area is reduced. This saves the user equipment investment cost and is recycling One of the ideal equipment for low temperature waste heat or using low temperature heat source.
2. Less scaling, convenient maintenance, removable and washable
High-intensity turbulence reduces fouling, is easy to clean and easy to disassemble and inspect.
3. Use different heating media
According to actual working conditions, the evaporation system can be heated by steam or hot water.
4. Easy to expand
If you want to increase or decrease the capacity, you only need to increase or decrease the heat exchange plates on the existing frame.
The capacity of the shell and tube evaporator is fixed and cannot be increased or decreased at will.
5. Less material retention and short retention time
The retention of materials in the plate evaporator is small, the residence time is short, and the entire evaporation process is gentle and uniform, which greatly improves the quality of heat-sensitive products.
6. Small footprint, easy to install and maintain
The design is compact, the connecting pipeline is short, and the overall height is small.
7. Easy to maintain and clean
