HRS Heat Exchangers models awarded sanitary approval

Georgia-based HRS Heat Exchangers has been awarded American 3-A Sanitary Standards approval for two of its heat exchanger models for food and beverage use.

The HRS MR Series and DTAR Series of hygienic corrugated tube heat exchangers earned the approval, completing the full range of HRS hygienic heat exchangers, including the R Series scraped surface model.

The approval recognizes design features including smooth welding and the ability of any surface that comes into contact with the exchangers to be mechanically cleaned or easily disassembled for cleaning and inspection, according to a news release.

The HRS MR Series of shell and tube corrugated tube heat exchangers are designed for product-to-product heat recovery. The MR Series is constructed from stainless steel for sanitary applications such as food and beverage manufacture.

The product flows through both the inner tube and the surrounding shell for regeneration duties, while the removable tubes allow hygienic processing on the shell side.

Product that has already been heated can be run past cold incoming product to pre-heat it, reducing the amount of energy needed to bring the new product up to pasteurization temperature, according to the release. A floating protection system eliminates the risks of cracks and cross-contamination.

In addition, HRS corrugation technology means that heat transfer and efficiency are increased over standard smooth tube heat exchangers while fouling is minimized.

The HRS DTAR Series boasts the same features as the MR Series but is designed for products with higher viscosities or which contain particulates.
