Explosion Proof Heater

---

Intertec Instrumentation Pvt Ltd offers Explosion Proof Heater.
Background
There are two different paradigms for electrical installations in hazardous areas worldwide:

• In North America UL, FM (USA) und CSA (Canada) electrical leads may only be installed inside rigid conduits. Exception: inside flameproof enclosures like electric motors normal cables may be used.
• Almost all other countries, IEC, ATEX (EU), GOST(GUS), GB3638 (China) etc: cables may be used, if they are installed mechanically protected

BI-Standard

• INTERTEC heaters for hazardous areas are build in a modular system. Many modules of this systems are the same for heaters with IEC certificate and American certificate (CSA C US)
• Therefore bi-standard heaters, that comply to both standards are possible. These heaters can be recognized by the letters BI in the type code
• They have two tags, each with the data due to the referring certificate

These heaters can be practically used world-wide.

Connection
IEC / ATEX heaters have an EEx d cable gland, (KLE) that completes the flame proof enclosure.. This KLE can be optionally equipped with a ½ NPT Adapter to be connected to a conduit. (2) The TS thermostat option integrated in the cable does not fit inside a ½“ conduit. (1) Versions …THERM Cxx and BI (with½“ NPT) are shipped with a red silicone plug to prevent the cable from damage.. This plug has to be removed to install a ½ NPT conduit.
