Techwell’s explosion-proof transmitters are certified for hazardous environments — including Ex ia IIC/Ma intrinsically safe ratings for coal mines, oil & gas, and Zone 1/Zone 2 classified areas.
Techwell explosion-proof remote controls are engineered for hazardous industrial environments where standard equipment falls short. As a trusted manufacturer of explosion-proof transmitters and explosion-proof push buttons, we provide certified industrial crane remote control systems for coal mines, oil & gas facilities, and other Zone 1/Zone 2 classified areas. Use the filters below to find the right explosion-proof transmitter or receiver series for your application.
Techwell holds core international certifications including Ex ia IIC intrinsically safe explosion-proof certification and SIL2 system-level functional safety compliance. Our explosion-proof transmitters meet Zone 1/Zone 2 hazardous area standards and are designed with intrinsically safe principles for use in coal mines, oil & gas, and other high-risk environments.
Ex ia IIC applies to general industrial hazardous environments (Zone 1/Zone 2), such as chemical plants and oil & gas facilities. Ex ia I is specifically for underground coal mining applications — for example, our FYF20(C) model holds MA certification (No. MFH220058) for underground coal mine use. The right certification depends on your specific hazardous area classification.
