Your Premier Chiller Manufacturer and Supplier in China Over 20 Years
The TOBEL TBEX Series Explosion-Proof Industrial Oil Chiller is specialized process cooling equipment engineered specifically for high-risk industrial environments containing flammable gases, vapors, or combustible dust. In hazardous atmospheres—such as chemical processing, oil & gas refineries, pharmaceutical manufacturing, and automated spray-painting workshops—standard cooling components like motors, compressors, and control panels can generate electrical sparks or dangerous surface heat. The TOBEL TBEX series eliminates these risks through rigorous explosion-proof engineering, certified electrical isolation, and heavy-duty thermal protection. It ensures 100% safe, stable, and continuous oil temperature regulation while preventing fire or explosion hazards.
The TBEX Series is designed to meet strict safety and operational standards in Zone 1, Zone 2, Zone 21, and Zone 22 hazardous industrial locations:
