Semi-Welded Heat Exchangers
Custom Semi-Welded Plate & Frame Heat Exchangers
CH Bull provides semi-welded plate and frame heat exchangers for demanding and specialized heat transfer applications. Their welded construction helps eliminate leakage concerns associated with traditional gasketed designs while supporting high temperatures, high pressures, cleanliness and corrosion resistance.
Semi-welded heat exchangers can be configured around the performance, capacity and material requirements of the application.
Semi-Welded Heat Exchanger Details
Semi-welded heat exchangers provide performance advantages for demanding applications involving high temperatures, high pressures, significant pressure differentials or high fluid volumes.
Performance & Construction
Semi-welded construction provides:
- Helps eliminate gasket-related leakage concerns
- Very high temperature ratings
- Very high pressure ratings
- Excellent corrosion resistance
- Ability to maintain pressure differentials
- High cleanliness
Pressure differentials can be significant, such as 50 PSI on one side and 300 PSI on the other.
Specialty Applications
Semi-welded heat exchangers are well suited for specialized heat transfer requirements, including:
- Ultrapure deionized water
- Steam/fluid heat exchange
- Highly corrosive fluids
- High-volume heating and cooling
Units can be sized to handle several thousand GPM of heated or cooled water.
Custom Configurations
Materials, size, capacity and other factors can be customized based on the requirements of the application.
Available materials include:
- Stainless steel
- Titanium
- Hastelloy
- Nickel
- Exotic alloys
