Ex room heaters and Ex finned tube heaters
Ex room heaters are used for heating room air in potentially explosive areas in zones 1, 2, 21 and 22. Ex finned tube heaters are used primarily for frost protection in containers, storage rooms, instrumentation rooms or similar rooms.
Room heater R1
Typ DHG11B01/R1
Ex heater with heating bundle made of tubular heating elements and integrated temperature monitoring devices
Ex room heaters comprise a heating bundle made of stainless steel tubular elements with a painted connection housing and protective cage.
The integrated temperature regulator is adjusted to the heater surface temperature and can be used indirectly with sufficient precision to regulate the room temperature. The temperature limiter monitors the maximum permissible surface temperature of the heating elements based on the applicable temperature class.
Ex finned tube heaters with protective cage
Typ DHG57A02/R2
Ex enclosure and protective cage painted, finned tube galvanised.
Ex finned tube heaters are used primarily for frost protection in containers, storage rooms, instrumentation rooms or similar rooms. They are suitable for room temperatures up to appr. 15 °C. Ex finned tube heaters are available in a standardised design according to the list.
A special ceramic heating inset is installed in a finned tube, which can be replaced via the attached pressure-resistant, encapsulated housing. The heating elements selected ensure that the applicable temperature class is not exceeded even in the event of an error (inadvertent covering).
For horizontal installation only!
Ex finned tube heaters without protective cage
Typ DHG57A02/R4
Ex enclosure, finned tube and mounting feet powder coated.
Ex finned tube heaters are used primarily for frost protection in containers, storage rooms, instrumentation rooms or similar rooms. They are suitable for room temperatures up to 15 °C. Ex finned tube heaters are available in a standardised design according to the list.
A special ceramic heating inset is installed in a finned tube, which can be replaced via the attached pressure-resistant, encapsulated housing. The heating elements selected ensure that the applicable temperature class is not exceeded even in the event of an error (inadvertent covering).
