Welded plate heat exchanger (ASV)


Lanpec welded plate heat exchangers provide efficient heat transfer with compact footprint, for the demanding process applications. They are designed for high pressure and high temperature, providing security when dealing with dangerous fluids. The heat exchangers are used in a wide range of cooling, heating, evaporation and condensing duties.

The welded plate heat exchanger (All be called as welded or fully welded type) adopts welding sealing structure, thus avoids the limitation of medium, temperature and pressure on the sealing gasket of traditional plate & frame heat exchangers, expands the application field and greatly improving its reliability.

Welded plate heat exchanger features all welded corrugated plates pack without gasket that produce highly turbulent flow in a true counter-current direction. The result is high efficiency in a very compact design. Due to the smaller size and reduced material content, welded plate heat exchangers can be the most economical heat transfer choice.

Two of the typical welded plate & frame heat exchanger configurations:

All frame components are bolted together for easily dismantling to clean and maintain the plate pack

The welded plate heat exchanger has the advantages of high heat transfer efficiency, strong self-cleaning ability, low metal consumption, compact structure, and small footprint. It can be widely used in electric power, petroleum, chemical, metallurgy, food, medicine and other fields.
