With the Transcal heat exchanger, the fluid moving in shell side is forced, by a system of spiral baffles, to take a helical flow. This form of flow makes it possible to increase the fluid velocity, therefore the exchange coefficient, without increasing the pressure drop. Or, by a spacing of these baffles, lower the pressure drops to save pumping energy.
This transverse and spiral flow system makes it possible, compared with conventional tube heat exchangers, to increase the heat exchange coefficients of several products having a higher viscosity than water.
The ability to maintain constant flow velocities by reducing the spaces between the baffles during steam condensation, allows the Transcal heat exchanger to have a very small exchange area compared to conventional heat exchangers, allowing to lower the price and reduce the size of the heat exchanger considerably.

Design and manufacturing
The only custom built heat exchanger at serial price. Manufacturing the parts in series significantly lowers manufacturing costs. As soon as there is steam or a liquid other than pure water, the size of the Transcal heat exchanger is up to 8 times smaller, and no technology can match its competitive price.
