Our WD-L and GG-L finned tube air heaters are designed for application in the home, the office or in industry. Because of the overheating protection and the low surface temperature, they are especially suitable for all heating applications at an ambient temperature of up to 30°C. Due to the fact that the construction is in accordance with IP65, they are also suitable for damp places. Because of the low surface temperature, they are safe to use in places of easy acces. The heaters are composed of an enclosed stainless steel tubular element, in which a glow-spiral is encased in a 1-phase construction. The connection is simple. It is possible to insert a second cable gland into the connection box. This will allow for the connection of an external room thermostat. A room thermostat 0-30°C (IP30) may also be placed on the lid of the box (in a dry environment).
