Sanitary Tube-in-Tube Heat Exchangers

Exergy Sanitary tube-in-tube heat exchangers consist of two tubes, an inner and an outer coiled together. This unique, compact design prevents thermal fatigue, increases efficiency and reduces the overall size. It is ideal for high temperature, high pressure and low flow applications.

These sanitary models are designed to meet the high quality requirements and hygienic standards of the pharmaceutical industry. All product contact surfaces have a maximum surface finish of 20µin (0.5µm) Ra, and can be improved to 15µin (0.38µm) Ra or better with optional electropolishing. Our unique design ensures there is no risk of cross-contamination between the product and working fluids.
