Plate Heat Exchanger Semi Welded Wide Gap Heat Exchanger

Advantage

Simple structure, easy maintenance, cost saving, high heat transfer efficiency and small occupied area, and the detachable structure can flexibly change the heat exchange area and the process combination by increasing or decreasing the number of plates or the commutator segments, and can be widely used in food, chemical, HVAC, pharmaceutical and other fields, such as preheaters, heaters, coolers, etc.

Free flow plate heat exchanger

The wide gap plate heat exchanger features a unique deep corrugated, non-contact design for media containing solid particles, crystals, fibers and pastes, as well as high viscosity media. It is especially suitable for the waste heat recovery device of papermaking black liquor cooler, concentrated pulp waste liquid and cellophane waste liquid.

Semi-welded plate heat exchanger

A semi-welded plate heat exchanger welds two plates together to form a sealed passage. The special medium flows in the welding channel and is only in contact with the two medium-resistant sealing rings at the inlet and outlet of the plate group.

The other side of the media is still sealed with a rubber gasket and can be removed if necessary. This structure allows each plate to be easily maintained while ensuring the stability of the welded plate set. It is especially suitable for handling fluids or gases that are aggressive and do not allow for leakage. Such as ammonia evaporator, sulfuric acid heat exchanger and so on.

Sanitary plate heat exchanger

Hygienic plate heat exchangers are plate heat exchangers designed for industries with strict hygiene requirements such as food, dairy, beverages and medicine. In addition to the general advantages of plate heat exchangers, it can also be designed as multi-stage, especially suitable for heat transfer of three or more media.

Hygienic plate heat exchanger can be used as pasteurizer, juice sterilizer, etc. for high temperature sterilization of heat sensitive materials and medical supplies such as milk, soy milk, juice, beverage, rice wine, beer, etc.
