FAQ

Shell & Tube heat exchangers are typically preferred for higher flow rates and larger heat loads where greater heat transfer surface area is required. Tube-in-Tube designs are well suited for lower-flow, high-pressure applications and processes with large temperature differences or significant thermal expansion. Exergy can help determine the best configuration based on your process conditions, space requirements, and performance needs.

Exergy sanitary heat exchangers are available with a standard internal surface finish of 20 µin Ra maximum. Electropolished surfaces down to 15 µin Ra are also available for applications requiring enhanced cleanability and a smoother product-contact surface.

A double tubesheet is recommended when additional protection against cross-contamination between the process and utility fluids is required. The design provides physical separation between the two fluid streams and allows potential leakage to be detected before the fluids can mix. It is commonly specified for pharmaceutical, biotech, WFI, and other high-purity processes.

Yes. Exergy can provide sanitary heat exchangers with electropolished product-contact surfaces for applications requiring enhanced cleanability and high-purity construction. Electropolishing can provide an internal surface finish down to 15 µin Ra.

To properly size a heat exchanger, Exergy typically needs the process and utility fluid types, inlet and desired outlet temperatures, flow rates, operating pressures, and allowable pressure drop. Information about material requirements, connections, available space, surface finish, and other application-specific requirements is also helpful.

Documentation is available based on the heat exchanger and application requirements and may include material certifications, drawings, surface finish documentation, weld documentation, pressure and leak test reports, and other applicable quality records. Additional documentation and validation packages can be provided when specified at the time of order.
