- : Plateflow heat exchangers provide more heat transfer in less space. No other technology is more compact, efficient or flexible. Plateflow offers “true” countercurrent flow maximizing the mean temperature difference between fluids.
- States: NC, SC, VA
- Industry / Applications
Plate and Frame heat exchangers use a combination of chevron-style heat transfer plates sequenced between a frame plate and pressure plate. The heat transfer plates have holes at the four corners forming a header that distribute the respective flows to the opposite sides of each plate when the plates align. The fluids are confined to the heat transfer surface of the plate or the port as appropriate with elastomer gaskets.
Features and Benefits:
Higher surface area to volume ratios than conventional shell and tube heat exchangersSuperior heat transfer coefficients compared to shell and tube heat exchangersOffers “true” countercurrent flow, which maximizes the mean temperature difference between fluids
Prevent intermixing of fluids due to a plate failure. Two plates are pressed together to ensure a tight fit to minimize heat transfer losses while maintaining a leak path in case of plate failure. Exceptional for refrigerant or corrosive chemical applications, and is ideal for situations where reducing the fluid's contact with elastomers is desired.
316SS or Titanium plates. Gaskets in Nitrile, EPDM, Viton, high temperature EPDM and high temperature Nitrile. Other materials upon request.
Semi-welded Plateflow design:
Utilizes two plates laser welded together to form a cassette. The cassettes form channels within which the fluid flows. One fluid flows within the welded cassette, the other fluid between the welded cassettes. Two ring gaskets and a field gasket are used between adjacent cassettes. This design reduces the welded-side’s exposed gasket surface by approximately 90%. Semi-welded designs available in 2.5″, 4″, 6″, 8″ 12″ and 18″ connection sizes. Exceptional for refrigerant or corrosive chemical applications, and is ideal for situations where reducing the fluid's contact with elastomers is desired.
Materials: 304 and 316 Stainless Steel, Titanium, SMO 254, Hastelloy, Incolloy, AL6XN Plates. Field gaskets in Nitrile, EPDM, Viton, high temperature EPDM and high temperature Nitrile. Ring gaskets in Nitrile, EPDM, Chloroprene, PTFE coated, and Viton. Other materials upon request.
Have wider plate gaps ranging from 5.4 mm to 11.5 mm and can handle fluids with particulate pulp or fibrous materials up to 2mm in diameter and 5mm long. Free-flow models feature minimum metal-to-metal contact points between elastomer adjacent plates to reduce points for particles to catch. Free-flow models available in 2″ to 12″ connection sizes.

Potable water applications, and pharmaceutical applications and engine cooling. Double wall plates reduce the possibility of fluids intermixing.
Refrigerant, aggressive chemical, or any applications where reducing the fluid’s contact with elastomers is desired.
For close temperature approach of fluids for heat recovery applications. Free-Flow feature is ideal for heat reclamation in pulp and paper, ethanol/biodiesel processes or chemical processing, where wash water, white water, fibrous water slurries or high viscosity fluids are used. Free-flow units have the added benefit of exceptional clog-resistance for high-fiber or coarse-fiber applications.
For heat recovery, equipment heating/cooling, make-up water preheating, chemical processes, central water, stator water, oil, auxiliary water, jacket water, drilling fluid.
