![]() | Convection Heaters Unitemp Air heaters are designed for heating of air and gases up to 600°C. Various construction options cater for applications ranging from climatic heating in buildings, process heating during manufacturing to heating of gas in the Chemical- and Petrochemical- Industry. |
Typical constructions:
| Low temperature duct heaters (Climatic control, drying processes): Elements are secured to the mounting plate by clinched bushes, allowing easy replacement of individual elements. A terminal cover protects the termination of the array. The array can be immersed directly into the duct. | ![]() |
| High temperature / high flow rate duct heaters (Curing, baking, processing): Elements are secured to the mounting plate by compression bushes, allowing easy replacement of individual elements. Low wiring compartment temperature is ensured by a thermal insulation layer above the mounting plate and an additional air gap between the termination area, allowing natural convection to further cool the rods. | ![]() |
| Finned elements (general purpose): Finned elements are used where space is limited and high heat transfer rate is required. | ![]() |
| Rod elements (general purpose): Rod elements offer economic and robust heating. They can be bent to any suitable shape and are mounted in ovens (still air) or in ducts (forced convection). |
