STEGO Heater CREx 020, Compact Thermostat REx 011:
Air as a medium can be malicious to electrical and electronic appliances. Absorption and release of water in the air within control cabinets creates the potential for the formation of condensate. Condensate, in turn, carries out corrosion processes on sensitive components and can freeze at minus degrees. Thermal Man-agement specialist STEGO also offers the right answer for hazardous environments.
With the proven expertise as heating manufacturer for panels & enclosures, STEGO meets the requirements of the Ex industry. The Ex heater series CREx 020 safeguards heating of switchgear and control cabinets as well as measuring devices in explosive atmospheres of zone 1 (gas atmospheres) and zone 21 (dust atmospheres) ac-cording to Ex protection class Ex II 2 GD. The maintenance-free convection heaters are available in three tem-perature classes (T3/T200 °C, T4/T135 °C and T5/T100 °C) and reliably prevent the harmful formation of con-densate, temperature fluctuations and frost in explosive atmospheres. The CREx 020 series achieves dust and splash protection according to protection type IP66.
