Graphite block heat exchangers are suitable for the heating, cooling, evaporation, condensation, and absorption of highly corrosive liquid chemicals. It is one of the most versatile types of impervious graphite heat exchangers. The process and service channels are formed by drilling rows of holes horizontally and vertically through graphite blocks. Heat is transferred by conduction through the impervious graphite left between the rows of holes that separate the media. Graphite block heat exchangers consist of a stack of blocks enclosed in a steel shell.
Why Use Graphite in Heat Exchangers? Due to its thermal and physical properties, graphite is an excellent heat transfer medium. These are some of its advantages: – Exceptional thermal conductivity – Easily machined – Capable of withstanding system stresses – Superior corrosion resistance – Low coefficient of thermal expansion (CTE) – High operational safety – Long service life BENEFITS OF GRAPHITE BLOCK HEAT EXCHANGERS: – High corrosion resistance of Graphilor® 3 – Compactness – Robustness – Modular design – Easy maintenance – Long lifetime – Service and maintenance in the US with two strategically located facilities – Manufacturing plant in the US
Types of Graphite Heat Exchangers for Corrosive Environments Graphite heat exchangers are available in many designs and configurations to suit different heat transfer processes. These include: Shell and Tube Graphite Heat Exchangers Multi-Blox Graphite Heat Exchangers Our Multi-BloxTM heat exchanger features some of the longest graphite composite blocks in the industry. The design reduces the need for gaskets, eliminates leak paths, and minimises point loading. With a maximum operating pressure of 150 PSIG, they are designed for non-stop service. Cubic Block Graphite Heat Exchangers The most efficient cubic block heat exchangers on the market with the highest heat transfer capabilities in the smallest area are available from us. They are easy to clean and maintain, and they are exceptionally durable.
