Plate and frame heat exchangers (PFX)

  • Summary
  • 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)

  • Description

    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.

  • Materials
    • Frames and pressure plates: stainless steel, painted carbon steel
    • Bolts: stainless steel, zinc-coated carbon steel
    • Support column (optional): stainless steel, painted carbon steel, aluminum
    • Plates: stainless steel, nickel alloys, titanium (-alloys)
    • Gaskets: elastomer materials, sigma coat, compressed fibers (non-asbestos)

  • Configuration

    Range of different connection types and materials. ASME code construction

  • Performance range
    • Standard models available in three pressure ratings: 100 psi, 150 psi, or 300 psi (690 kPa, 1034 kPa and 2068 kPa)
    • Custom designs available for higher pressure requirements
  • Power Range

    N/A

Low installed cost

  • Superior heat transfer coefficients of Armstrong PFX exchangers allow for smaller build and footprint at equivalent or better performance compared to other heat transfer devices – resulting in significant space savings
  • Highly compact design for fast and convenient installation in tight spaces 
Design Envelope

Lowest installed cost. Lowest operating cost.

»

Superior heat transfer rates and excellent building comfort

  • Turbulent-flow design moves the two media in opposite directions and creates strong turbulences for superior heat transfer rates and efficiency
  • Highest responsiveness to changes in system demand for superior space conditioning compared to other similar designs
