These equipment, as a previous step to cleaning, avoid gases from getting to the cleaning systems at a too high temperature.For use in:• Solvent incineration installations in the automotive industry. • Cogeneration installations. • Metal and plastic surfaces treatment installations. that contains it, so avoiding pos s i b l e b r eak s a s a consequence of the different thermal expansions between the bundle and the frame, adding compensators or bending the bundle tubes. GASES-AIR HEAT EXCHANGERSThey are equipment with a more compact design, which allows a quick and easy assembly.In a heat exchanger the tube bundle is fixed to the frameFor higher working pressures the ring arranged tubes cage recuperators offer a better performance, a higher resistance and a more homogeneous air distribution.They are designed replacing the interior shell by a ring arranged tubes cage, though which the air flows, so that the heat transfer is still made by radiation.They allow reductions of fuel consumption by preheating combustion air up to 40%, with a compact design that facilitates the installation.Double shell radiation recuperators are made of two concentric cylinders in which the secondary fluid flows through the circular crown, either in paralell to the recuperator axis or helicoidally, counterflow or in parallel drafts, and are appropriate for working pressures up to 2.000 mm.
