Casing | 316 perforated stainless steel |
Element | Self-regulating |
Controls | The HEF is self-regulating, automatically reducing its output as the ambient temperature rises. If overall enclosure temperature control is required, it is recommended that the HEF heater be used in conjunction with the AFT, HFT or FXT flameproof air sensing thermostats |
Mounting | The heater may be mounted in any orientation, using appropriate securing bolts through the mounting feet or DIN rail holes |
Rating | The HEF range is available in a nominal 30W, 50W, 100W, 200W and 500W outputs |
Voltage | Models available for 110V to 120V and 230V to 240V 1 phase supplies (max 254V subject to design parameters) |
