Description
BKF IIB Explosion Proof Air Conditioner R410A – 18,000 BTU (BKF-50/220EU)
The BKF IIB Explosion Proof Air Conditioner (18,000 BTU) is a wall-mounted cooling system engineered for hazardous locations where flammable gases may be present. Built for ATEX and IECEx environments (IIB), it delivers reliable climate control for industrial facilities such as oil & gas sites, chemical plants, and utility rooms where standard HVAC equipment is not permitted.
This 18,000 BTU configuration uses R410A refrigerant and integrates explosion-protected components across the system—covering the compressor, fan motors, and control stations—plus an explosion-proof control box with intrinsically safe circuits. The result is safer cooling performance across harsh operating conditions, with ambient temperature ranges supported from -7°C up to +52°C depending on configuration.
Key Features:
✅ ATEX & IECEx certified (IIB) for hazardous gas environments
✅ Control system: Explosion-proof control box + intrinsically safe sensor/control circuits
✅ Certified explosion-protected components (Ex d / Ex nC / Ex ib concepts across units)
✅ Connectivity: Not applicable (HVAC system)
✅ Cooling capacity: 18,000 BTU (5,275 W) using R410A refrigerant
✅ Safety design includes explosion-proof treatment of compressor, fan motors, and control stations
✅ Ambient temperature support: -7°C to +43°C or up to +52°C (configuration dependent)
✅ Not applicable (AR/Biometrics)
✅ Wall-mounted installation for industrial rooms and hazardous-area buildings
