ATEX Gas Bottle Heater | WEXHB
WEXHb Series | gas bottle cylinder heater
Product Code: WEXHB
The WEXHB ATEX Gas Bottle Cylinder Heaters are specially developed heating systems designed for potentially explosive environments, including chemical, petrochemical, and pharmaceutical industries. These solutions are certified in accordance with ATEX directives, ensuring their safety and reliability in hazardous areas.
Product Overview
WEXHB ATEX gas bottle heaters manufactured by winkler are designed to provide effective frost protection, temperature maintenance, and controlled process heating for pressurised gas cylinders operating in ambient temperatures from –40 °C to +50 °C. These heating jackets are widely used where stable gas extraction and processing are essential, preventing pressure loss, condensation, and flow interruption caused by low temperatures.
The gas cylinder heaters feature a robust, weather-resistant construction with IP65 ingress protection, making them suitable for both indoor and outdoor installations. Fully ATEX certified, WEXHB heaters are approved for use in Zone 1 and Zone 2 hazardous areas, ensuring safe operation in potentially explosive atmospheres.
