Sanitary heat exchangers are often required in the food and pharmaceutical industries. Constructed similarly to typical heat exchangers, sanitary exchangers can have special design requirements such as;
- Rolled or seal welded joints
- Polished surfaces
- Sanitary tri-clamp fittings
- Teflon©, Gylon Fawn, Viton© or other special gasket materials
- Manufactured to 3a Standards and Stamped
- Clean in place design
Standard and Custom Designs are available
Standards and Options
- 304 and 316 stainless steel, 1.4435 SS, Hastelloy ®, Inconel® and other materials.
- Can be nickel brazed (no welds).
- Double tubesheets to prevent cross-circuit contamination. (Click here for more information)
- Seal welded tubes to prevent leakage and insure against bacterial growth.
- The tube side is completely drainable.
- All product contact surfaces have a maximum surface finish of 20µin Ra.
- Surface finish can be improved to 15 µin Ra with optional electropolishing.
- Passivation and/or electropolished product contact surfaces as an option.
- Available in U-tube or straight tube, fixed tube sheet designs.
- Fittings may be; NPT threaded, Sanitary Tri-clamp, or ANSI flanged connections.
- Upgrades to 3-A or double tubesheet design for high purity applications.
- Can be supplied to 3A Standards. Standard 12-07 is available as an upgrade.
- Clean in place (CIP) design.
- ASME BPE sanitary fittings.
- ASME BPE compliant.
- Can be a constructed to TEMA C.
