Flue gas and process heat
The high-temperature heat recovery units in the Safe Series from exodraft recover unused energy from flue gases and process air. The units are designed to operate in flue gas temperatures up to 400 °C on air side.
The housing of the Safe Series units consists of stainless steel 1.4404 (internal)and 1.4301 (external) and is protected against radiation losses with a highly effective insulation while a built-in drain ensures disposal of condensation.
The highly efficient plate heat exchangers, which consists of stainless steel (copper brazed joints) is distinguished by its robustness and its efficient heat transmission, courtesy of its unique design.
The plate heat exchangers are quick and easy to remove for cleaning and maintenance, thereby reducing the maintenance work to a minimum of time.
When no heat is required the hot flue gases or process air are passed through an integrated bypass. This bypass protects the system from overheating and is also activated if heat consumption no longer occurs. Additionally, the bypass prevents critical pressure loss. The exodraft heat exchangers have a minimal space requirement due to their compact design.
Not suitable for solid fuel units (wood, coal, biomass, etc.).
The Safe Plate units come with four lifting eyes which can be repositioned, allowing for both horizontal and vertical mouting orientations.
As an alternative to the standard copper brazed heat exchanger, the Safe Series also offers a nickel brazed option that is more suited for installation in corrosive environments.
The Safe Series units are intended for indoor installation, but can be installed outdoors if the unit is covered/encapsulated properly.
