Hazardous Area Technical FAQ
What is Zone 1 vs Zone 2 in hazardous area classification?
Zone 1 is an area where an explosive gas atmosphere is likely to occur during normal operation (>10 hours/year, <1,000 hours/year). Zone 2 is where it is unlikely during normal operation and only persists for short periods (<10 hours/year). Our Ex d IIC T6 Gb housings are certified for both Zone 1 and Zone 2, while our Ex e junction boxes are suitable for Zone 2 increased safety applications.
How do your enclosures prevent gas explosions?
Our enclosures use the Ex d flameproof protection method. The housing is engineered with precision-machined flame paths (gaps < 0.03mm tolerance) between the body and lid. If flammable gas enters and ignites inside, the explosion is contained. Escaping gases are forced through the flame path, which cools them below the auto-ignition temperature before they reach the external atmosphere — the same principle used in industrial flame arrestors.
What maintenance does explosion-proof equipment require?
Routine maintenance includes: (1) visual inspection of flame path surfaces for corrosion or damage — any pitting invalidates the Ex certification; (2) O-ring inspection and replacement every 2 years; (3) cable gland compression check during annual safety audits; (4) earth bonding continuity test per IEC 60079-14. Our quick-release wiper blade system enables single-person replacement in 90 seconds without opening the sealed enclosure.
Can your housings operate in extreme temperatures?
Standard operating range is -40°C to +60°C (ambient). The integrated PTC heater self-regulates power based on temperature, preventing condensation and lens fogging at low temperatures without a mechanical thermostat that could fail. The forced convection sunshield design reduces internal temperature by up to 15°C in desert sun. Extended temperature ranges available on request.
