​-20℃ Low-Temperature Ex Welding Chamber Solution

Safety Guarantee for Low-Temperature Operations In the alpine environments of oil drilling platforms, conventional welding equipment is prone to malfunction due to low temperatures, and the risk of flammable and explosive medium leakage surges sharply. The ATEX-certified positive-pressure explosion-proof welding chamber specifically addresses this pain point.

 Equipped with a customized T3-class explosion-proof heater and a closed thermal insulation layer, the chamber stably maintains the internal operating temperature. The 550℃ fire-resistant tarpaulin isolates external low-temperature intrusion and prevents heat loss inside. The intelligent monitoring system achieves real-time linkage between gas detectors and positive-pressure fans, which can accurately capture combustible gas concentrations even in low-temperature environments. When exceeding the standard, it automatically triggers sound and light alarms as well as ventilation pressurization.

Adopting low-temperature resistant components, the equipment is suitable for a wide temperature operating range of -20℃~+60℃ and can be started without additional preheating. It builds a solid safety barrier for hot work in alpine regions and achieves dual compliance of efficiency and regulatory requirements.
