Welwyn Tool Group Ltd

The latest generation of double-flange air heaters is specially designed to be used in the hot air recirculation mode. Depending on the air inlet and air outlet temperature, a massive amount of energy can be saved by "recycling" hot air. This not only saves on expenses, it also protects the environment. On the inlet side, the device can easily tolerate temperatures up to 350°C.Maximum Air inlet temperature 350°C.

Double flange air heater. Suitable for hot air recirculation.

High temperature air heater up to 900ºC, without electronics. Power consumption: 11 kW; Max. outlet temperature: 900ºC Max. air inlet temperature: 100ºC Max. ambient temperature: 100ºC Min. air flow: 600 l/Min. Weight: 2.25kg

The world's smallest air heater. Especially suited for applications in which heat is concentrated to a point.

This advanced air heater is distinguished by its extremely small dimension - especially the lean design at only 67 mm width - as well as its long service life. It provides hot-air up to 650ºC and includes a long-life heating element, reliable protection systems and standard interfaces. This makes it perfect for applications in the Semiconductor, Electronics, Automotive and other industries.
