The Ultimate Solution for High-Efficiency Continuous Heat Exchange


The QuadTherm is a compact, high-efficiency continuous heat exchange system for rapid heating or cooling of almost any product of low-to-high viscosity that is transferrable by pump. A well-mixed heat exchanger ensures even heating/cooling and eliminates the risk of undercooked products. The QuadTherm rotor and scraper systems undergo a great deal of computerized and empirical qualification and are further scrutinized under strict QA protocols.
