Description

The G-Plate plate-type heat exchanger consists of a
number of embossed and sealed plates. Depending on the application, all cold-drawing materials, such as:

  • Stainless steel
  • Nickel alloys
  • Titanium
  • 254 SMO
  • Hastelloy

and other materials are can be used, to name only a few. The plates are mounted between the upper and lower guide rail and clamped between the two frame platesy bolts.The seals are elastomers used as required by temperature, pressure and the chemical properties of the two media, e.g.:

  • NBR
  • EPDM
  • FKM (Viton), etc.

and other sealing materials.
Mixing of the two media in case of defective seal is prevented by double seals at the transition openings and the leakage space in-between, which is open to the outside. Any leak will be detected from outside immediately before the two media have a chance of mixing through the seal.

Design Conditions
  • Operating temperatures from -20 °C to 155 °C
  • Operating pressure up to 25 bar, suitable for
    vacuum
  • Plate thicknesses from 0.4 to 0.9 mm
  • Compact design, can be expanded
  • Very high heat transfer coefficient
  • Low-wear and requiring little maintenance
  • Wide range of materials
  • Suitable for many different media
 
Special types of G-Plate

• G-Plate-Free-flow.

Plate heat exchangers whose large spacing between plates (without points of contact) allows processing fluids with particles.


• The G-Plate-DW (“Double-wall”)

Is a safety plate-type heat exchanger which prevents the mixing of media due to cracks or corrosion in the plate pack.
This is ensured in that 2 plates are placed loosely one upon the other and a glueless bond established between both in the inlet and outlet areas. The hole
diameter of the top plate is larger than that of the bottom plate.

A very small air gap of ambient pressure forms between both plates. If one of the two plates is damaged, the medium emerges from the gap between the plates and will be visible. The leak can be detected immediately. The plates are not welded and therefore can be made of different materials.


• G-Plate- semi-welded

For applications for which no suitable seals are available, e.g., high-pressure environments, temperatures or critical media, the semi-welded plate heat exchanger is the perfect solution. These heat exchangers are used, for example, as evaporators and condensers, e.g., refrigerant NH3 or freon, and are an alternative to tubular heat exchangers.
