Welded Plate Heat Exchanger

Bloc Type Welded Plate Heat Exchanger is made up of plate pack and frame. The plate pack is formed by welding a certain number of plates, then it is installed into a frame, which is configured by four corner girders, top and bottom plates and four side covers. 

Welded Block Plate Heat Exchangers deliver high heat-transfer efficiency in a compact footprint, ideal for high pressure / high temperature and aggressive media where gasketed plate exchangers are not suitable.

We manufacture and supply Welded Block Plate Heat Exchangers designed for demanding process duties in chemical, petrochemical, refinery, and power applications. The plate pack is fully welded (gasket-free), enabling safe operation with high pressures, high temperatures, and corrosive fluids. Its compact design reduces space requirement and improves thermal performance compared to conventional shell & tube in many duties.

Key Benefits

• Gasket-free welded construction (low leakage risk)

• Handles higher pressure/temperature than gasketed PHE

• High turbulence → high heat transfer coefficient

• Compact, low hold-up, faster response

• Suitable for fouling / aggressive services (design dependent)
