Explosion Proof Stainless Steel Finned Tube Heaters type ERB

The Sinus Jevi D8500 gas and dust explosion-proof finned-tube heater has rolled-in ribs, similar to the standard finned-tube heaters. The heating element is composed of stacked stones. The Sinus Jevi explosion-proof finned tube heaters are ISSeP approved and comply with the norms laid down in the European Norms (European Standards) EN-IEC-60079-0 and EN-IEC-60079-31.
The pressure-resistant construction is approved for gas groups I, IIA, IIB and IIC. Safety from explosion is ensured by a flame proof construction with direct connection (construction d), a maximum surface temperature of 200°C at an ambient temperature of 40°C and a screw lid, whereby the leakage path complies with the requirements laid down for  (connection) boxes of the IIC class. Therefore, the Sinus Jevi explosion-proof finned-tube heater is in line with temperature class T3 and, in accordance with the Norms, it is provided with the reference mark Ex db IIC T3 Gb and Ex tb IIIC T200°C Db.
Through reduction of output, a flame proof construction with a maximum surface temperature of 135°C is obtained, thus meeting the requirements of temperature class T4. Class T4 is provided with reference mark Ex db IIC T4 Gb and Ex tb IIIC T135°C Db.


The Sinus Jevi explosion-proof finned-tube heaters can be used for heating areas where all possible gases or vapours may be present; for example: on oil/gas rigs, in the chemical and petrochemical industries and areas where combustible and/or inflammable products are stored. On mounting, we recommend that you read the installation manual.
The explosion-proof finned-tube heaters can be regulated by means of an explosion-proof thermostat, type ERT-10.
