Silicon carbide shell and tube heat exchangers

Silicon carbide shell and tube heat exchangers

CORRESIC® Silicon carbide shell and tube heat exchangers are adapted to the cooling, condensation, heating, evaporation and absorption of highly corrosive chemicals. Silicon carbide shell and tube heat exchangers consist in a bundle of silicon carbide tubes inside a shell. One fluid runs through the tubes and another fluid flows over the tubes (through the shell). The heat is transferred by conduction through the silicon carbide tube wall, without direct contact between the fluids.

Shell and tube heat exchangers

Their modular and versatile design allows very efficient heat transfer thanks to adjustable cross sections on both sides that guaranty a high level of turbulence.

The thermal performance of shell and tube heat exchangers can vary significantly. It is therefore essential to select the type and size of shell and tube heat exchangers (tube count, tube diameter, tube length, pitch, baffle count, opening) that is the most adapted to the specific application and industrial process. There are a number of considerations including flow rate, pressure drop, design pressure and temperature, materials compatibility, fouling, and many more that should be taken in account.

GAB Neumann’s silicon carbide shell and tube heat exchangers SR series

GAB Neumann’s silicon carbide shell and tube heat exchangers are designed to condense, cool down, heat up, evaporate or absorb ultra-corrosive and/or oxidizing fluids. Safety, reliability, and performance on the long-term are our primary considerations when we size, design and manufacture SiC shell and tube heat exchangers.

Our extended and highly customizable silicon carbide shell and tube heat exchangers portfolio enables us to provide particularly adapted solutions to the most complex heat transfer challenges. All our SiC shell and tube heat exchangers designs are totally modular to best fit with individual process specification. The number, length and diameter of tubes 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.

On request, they can be fitted with optional features such as sight glasses and cleaning in place.

Our SiC shell and tube heat exchangers are all fitted with GAB Neumann’s unique and upmost reliable triple tube sheet double O’ring gasket sealing system that guaranties the performance of the equipment on the long term.
