Paul Mueller Company's Accu-Therm® units are a reliable heat transfer solution for a variety of industries and applications. We have four types of plate heat exchangers: The original plate heat exchanger, sanitary plate heat exchanger, semi-welded plate heat exchanger, and brazed plate heat exchangers. Each offers an extensive range of options and can easily be sized with our Accu-Calc sizing program. Accu-Therm units continue to provide an efficient alternative to traditional shell & tube heat exchangers with less carbon footprint. Maintenance is a breeze with the unit’s expandable frame, offering easy access for removing and cleaning plates.
