(1) High heat transfer efficiency, K value is generally 3500 ~ 5800kW / (m2 · K), 2 to 4 times higher than shell and tube evaporator;
(2) Compact structure and small size;
(3) light weight, thin heat transfer plate, small metal consumption, about 10kg of metal per square meter of heating area, only 1/3 to 1/4 of the tube heater;
(4) The material has a short residence time in the heater, less internal dead angle, good sanitary conditions, and is suitable for evaporation of heat sensitive materials;
(5) Flexible operation, large amount of wealth, can increase or decrease the number of plates according to needs, the heat exchange area of each unit can be between 1 and 1600 m2;
(6) The low-temperature heat source can be used and recovered, and the heat transfer temperature difference between the hot and cold materials can be reduced to 4 to 5 °C.
