The Armstrong PFX plate and frame heat exchangers consist of a number of specially corrugated metal plates assembled in a frame and bolted between two pressure plates (one fixed and one adjustable.) Armstrong plate designs are optimized for best water-to-water heat transfer providing enhanced performance especially in HVAC applications.

Applications: Central HVAC and ancillary cooling, lube oil coolers (turbines), seal water coolers (vacuum pumps), gearbox oil cooling (wind turbines), ground water isolation exchangers (geothermal).
