Fully Welded Plate Heat Exchangers

Heavy Duty Application

• Maximum Operating Temperature: 400°C
• Maximum Work Pressure: 35 bar

Compared to S&T HE

• Compact (up to 3-4 times less heat transfer area) which can save big when exotic materials are to be used.
• Smaller footprint.
• Lower operating and maintenance costs.

Compared to Gasket PHE

• No rubber gaskets are used thus lower maintenance cost and less chance of external leaks.
• Capable of operating at much higher operating temperatures & pressures.

The plates of the fully welded Heat Exchangers are thicker than the plates of a Gasket type Plate Heat Exchanger, this allows for welding the plates together. Our standard thicknesses are 0.8mm and 1.0mm, standard plate materials are 304L or 316L, however more exotic materials can be used. The Welded Plate Heat Exchanger has a channel gap of 5mm and combined with turbulent flow, fouling is less prominent compared to S&T HE’s for the same application.

Another feature is the special design between connections and plate entry eliminating “dead zone” in the corners of the plates. These dead zones are often seeding points for fouling and sedimentation.

Cleaning & Maintenance

Depending on the configuration of the Heat Exchanger, either one side or both sides can be opened for cleaning, inspections, and maintenance.
