Plate & Frame Heat Exchanger

Plate & Frame Heat Exchanger

Assisting our Plate & Frame customers in maximizing reliability and productivity for over 16 years, expect a quick and professional response from NHE’s expert service team.

National Heat Exchange thoroughly cleans Plate & Frame units with chemical circulation, high pressure wash and chemical soak. After disassembly and testing, any necessary repairs are made, leaving the unit ready for assembly and a fresh coat of paint. Cleaned and painted units are then hydro-tested and inspected. Our proven techniques return heat exchangers to 98% of original output.

We are an Approved Service Center for the following OEM’s:
