Heat Exchangers

Heat Exchangers.

Custom Fabricated.

Our heat exchanger vessels are designed for heating or cooling. Pressure applications are typical as the energy stored will affect the temperature on pressure changes. The design of a heat exchanger is carried out according to customer specs and ASME Sec VIII, Div 1.
Typical applications include:

• Coolers
• Condensers
• Evaporators
• Heaters
• Preheaters
• Reboilers
• LNG STV’s and Vaporizers

Our options for customization does not limit the application. If your business needs special options for your heat exchanger, you can work with our team of engineers to develop the solution. Below are capabilities, materials, features, and options made available to our customers.
