WPCHE developed using innovative hydroforming technique which makes them cost effective and easy to manufacture. Welded Plate Compact Heat Exchanger (WPHE) is special kind of compact heat exchanger which can endure high temperature and pressure avoiding leakage for handling toxic and radioactive coolants. Commercial WPHE are made by traditional cold forming (die and punch technique) which makes them costly and proprietary in nature.

1. Welded plate compact heat exchanger (WPHE) can endure high temperature and high-pressure avoiding leakages for handling toxic and radioactive coolants.
2. WPHE is used in oil and gas industry, refinery applications, pharmaceutical industry, chemical/petrochemical industry and nuclear industry.
3. Developed WPCHE has very high compactness of 400 m2/m3, so it can be used in areas with space limitation.

The main advantages of Weld Plate Compact Heat Exchanger (WPCHE) over conventional heat exchangers are as follows:

1. WPCHE is smaller and lighter compare to convention shell and tube heat exchangers.
2. Gasket free maintenance since it doesn't use gaskets.
3. Developed WPCHE uses hydro-forming technique for manufacturing of WPCHE cassettes. Other commercial WPHE are made by traditional cold forming (die and punch technique) which makes them costly and proprietary in nature.
4. Modular design, easily scalable for MW rating.
5. Very low initial investment due to hydro-forming technique.

WPCHE using innovative hydroforming technique makes them cost effective and easy to manufacture. Plate Cassettes with optimized corrugation design for better thermal hydraulics performance and high-pressure application has been developed and utilized in WPCHE. Two 1 mm thick flat plates (300 mm X300 mm) welded all around with diagonally opposite inlet and outlet tubes to make single welded plate cassette. Welded plate cassette is then sand-witched between two wire-messed thick Flanges and tightened. Welded plate cassette is then pressurized upto 300 bar to get the designed corrugation. Corrugated welded plate cassette is then assembled to make Welded plate compact HX (WPCHE) with compactness of 400 m2/m3.
