● Custom Gears for High Stability
Custom-designed gears provide high transmission efficiency. Paired with a dedicated barrier gate gearbox, they ensure exceptionally smooth and stable operation.
● Smooth Raising with Multiple Speed Ratios
The raising and lowering speed is adjustable from 1.2 to 3 seconds based on user requirements. Features manual bar lifting during power outages and automatic reset upon power restoration.
● IP66 Protection for All-Weather Use
Built to withstand wind, sun, extreme cold, and heat, ensuring reliable and stable performance even in harsh environmental conditions.
CNWINNEX explosion-proof systems are widely deployed in oil & gas, petrochemicals, pharmaceuticals, ports & terminals, mining, power generation, offshore platforms, and other areas where flammable gases or dusts are present. Typical applications include control room climate control, hazardous area logistics and access management, video surveillance & security, pressurized analyzer shelters, robotic inspection, as well as custom explosion-proof enclosures and system integration.
An explosion-proof air conditioner is a specialized HVAC unit designed for hazardous environments where flammable gases, vapors, or combustible dusts are present (e.g., petrochemical plants, gas stations, paint booths, pharmaceutical labs).
The most critical difference from a standard air conditioner lies in “active ignition prevention.” Standard units generate tiny sparks during normal operation – such as when relays open/close, compressors start/stop, or circuits make/break. While safe in normal air, these sparks can be deadly in an explosive atmosphere.
CNWINNEX’s explosion-proof design is based on the T4 temperature class. For high-temperature regions such as the Middle East or areas with extreme summer heat, we offer custom units rated for ambient temperatures up to 60°C (140°F) , ensuring reliable operation without overload in harsh tropical climates. For cold regions, we offer custom units rated for ambient temperatures as low as -50°C (-58°F) , guaranteeing safe operation in extreme arctic conditions.
The explosion-proof rating of CNWINNEX air conditioners is:
