Gasketed plate heat exchanger benefits

  • Precision heat transfer – closer approach temperature, true counter current flow, 80-90% less hold-up volume
  • Low overall cost – low capital investment, reduced installation costs, limited maintenance and operating costs
  • Maximum reliability – less fouling, stress, wear and corrosion
  • Environmentally responsible – minimum energy consumption for maximum process effect, reduced cleaning
  • Easy to expand capacity – simply add or remove plates on the existing frame

Efficient heat transfer

Gasketed plate-and-frame heat exchangers (GPHEs) provide efficient heat transfer in compact equipment with a small footprint – much smaller and more efficient than shell-and-tube heat exchangers. Our wide range of products is used in duties for heating, cooling, heat recovery, evaporation, and condensation in industries such as HVAC, refrigeration, engine cooling, dairy and food, chemical processing, oil production, power generation and more.

Plate heat exchangers are designed to optimize heat transfer, because the corrugated plates provide by far the greatest surface area through which the heat can be drawn from one gas or liquid to the other. The units also have a flexible design and are easy to service and maintain.

How GPHEs work

The concept behind a heat exchanger is relatively simple – heating or cooling one medium by transferring heat between it and another one.

In a gasketed plate heat exchanger, the plates are fitted with elastomeric gaskets which seal the channels and direct the media into alternate channels. The plate pack is assembled between a frame plate and a pressure plate and compressed by tightening bolts fitted between these plates. The channel plates and the pressure plate are suspended from an upper carrying bar and fixed in position by a lower guiding bar, both of which are fixed to the support column. The design allows easy cleaning and simple capacity modification (by removing or adding plates).

The heat transfer area of a gasketed plate heat exchanger consists of a series of corrugated plates, assembled between a frame and pressure plates to retain pressure. Gaskets act as seals between the plates.

Fluids normally run counter-currently through the heat exchanger. This gives the most efficient thermal performance and enables a very close temperature approach, i.e., the temperature difference between the exiting process medium and the entering service medium. For heat sensitive or viscous media, co-current flow can be used to let the coldest fluid meet the hottest when entering the heat exchanger. This minimizes the risk of the media overheating or freezing.

Our thermal design engineers can help you design and select the model and configuration that is suitable for your application so that it delivers maximum thermal performance with minimum pressure drop.
