Graphite plate heat exchangers
Impervious graphite plate heat exchangers
Impervious graphite plate heat exchangers are adapted to the heating and cooling of highly corrosive chemicals. This design is the most compact and most efficient type of impervious graphite heat exchangers.
Our impervious graphite plate heat exchangers are made of many 10 mm thin graphite plates that have very large surface areas and small fluid flow channels for heat transfer.
Heat is transferred by conduction through the graphite plates material.
Plate exchangers work with countercurrent flows which allows low temperature differences, rapid temperature changes, and high efficiencies.

Plate & frame heat exchanger
Plate & frame heat exchangers are made of many 10 mm thin plates that have very large surface areas and small fluid flow channels for heat transfer. Heat is transferred by conduction through the plate's material. Plate heat exchangers work with countercurrent flows which allows lower approach temperature differences, high temperature changes, and increased efficiencies.
The thermal performance of plate heat exchangers can vary significantly. It is therefore essential to select the type and size of plate & frame heat exchanger that is the most adapted to the specific application and industrial process. There are several considerations including flow rate, pressure drop, risk of erosion, design pressure and temperature, materials compatibility, fouling, and many more that should be taken in account.
