Bell & Gossett GPX® High Energy Efficiency Gasketed Plate and Frame Heat Exchangers

Overview Solutions Documentation & Tools

Maximum efficiency in less space, with outstanding application flexibility

Innovative plate design allows GPX heat exchangers to provide more heat transfer using less space. They perform with one-third to one-fifth the surface area of conventional shell and tube heat exchangers designed for the same application.

  • GPX models have higher surface area to volume ratios than conventional shell and tube heat exchangers
  • GPX offer superior heat transfer coefficients compared to shell and tube heat exchangers
  • GPX offers “true” countercurrent flow, which maximizes the mean temperature difference between fluids
Product Features
  • Compact, low cost, high energy efficiency solution
  • Up to 20% increase in heat transfer thermal performance
  • Up to 20% reduction in surface area
  • Up to 15% reduction in material
  • Reduced operating cost
  • Reduced environmental impact

Expansive product line meets a variety of needs

The GPX line has the capability to meet any size application, and it offers a wide variety of plate construction materials and connection types. You can choose products constructed from 304 or 316 stainless steel, titanium, Hastelloy, ® Incolloy® or other metals. Plates can be gasketed, semi-welded, double wall, or free flow, depending on your particular application.

Advanced GPX system offers superior efficiency

GPX uses 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 that form a header, which distributes the respective fluids 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. Countercurrent flow is obtained with a given fluid traveling up one side of a plate and the other fluid down the opposite side of the plate. The plate’s chevron patterns create metal-to-metal contact points between adjacent plates for added strength. This allows differential pressures equal to the design pressure. The entire assembly is held together with tightening bolts. Carry/guide bars are used to obtain the proper alignment.
