GAB Neumann’s has an extended experience in the sizing, design and manufacturing of graphite heat exchanger. Over the last 50 some years we have designed, adapted and/or customized our products to best meet with the highly specific and sometimes unique requirements (multiple stages condensation, crystallization, continuous reactor, reverse sublimation, etc…) of our customers.
A heat exchanger is a process device which transfers heat from one medium to another without direct contact between fluids. For material properties, cost and efficiency reasons we design custom-made heat exchangers exclusively in impervious graphite and silicon carbide. Heat is transferred by conduction through the exchanger material left between the channels or rows of holes which separate the media being used.
Our standard pieces of process equipment are totally modular. It is therefore possible to combine and customize bits and pieces from one series of process equipment with other series to form custom-made pieces of equipment that are ultimately perfectly adapted to unique process requirements. Our custom-made heat exchangers can combine the heating, cooling, evaporation, condensation and absorption of highly corrosive chemicals.
The thermal performance of heat exchangers can vary significantly. It is therefore essential to select the type and size of heat exchanger that is the most adapted to the specific application and industrial process. There are a number of considerations including flow rate, pressure drop, risk of erosion, design pressure and temperature, materials compatibility, fooling, and many more that should be taken in account.
GAB Neumann’s custom-made graphite heat exchangers are designed to meet specific process requirements. They are designed to cool down, condense, heat up, evaporate, sublime, crystallize, absorb, separate, and/or mix ultra-corrosive chemicals. Safety, reliability, availability, and performance on the long-term are always our primary considerations when we size, design and manufacture custom-made graphite heat exchangers.
Our extended, modular, and highly customizable graphite heat exchanger portfolio enables us to design specific solutions to ultra-corrosive heat transfers. All the parameters (size, diameters, channel widths and depths, height, cross sections, heat transfer surfaces, as well as the number of passes both on process and service sides) can be adapted to best meet the velocities, pressure drops, and heat transfer requirements.
They can be fitted with all kinds of optional features such as sight glasses, additional nozzles, sensors, or demountable headers to better fit the process requirements.
