ATEX Heating Jackets & Mats

Heating Jackets | Bespoke & Standard | Available From Stock | Contact Us Today

The WEXH series of ATEX heating jackets and mats are used for protection against frost, temperature maintenance and process heating in the temperature range from -40 °C to +200 °C. Heating jackets are used to provide frost protection, conserve heat and maintain plant process temperatures to prevent viscosity loss, coagulation, clogging or freezing.

Together with Winkler, Thorne & Derrick can offer a wide range of standard and bespoke heating solutions suitable for use in explosive atmospheres (zones 1/2 gas, 21/22 dust). The heating jackets can be designed and manufactured to fit virtually any size or shape e.g. vessels, drums, bottle cylinders, containers, columns and reactors.

The tailored service offers ideal solutions for customers requiring non-standard containers in a range of power, voltage, material and control options. Heating Jackets are also available for special gas cylinder applications.

Contact us to discuss the initial concept, agree a bespoke design, start manufacture and deliver on short lead times to support your Winterisation measures to prevent cold-weather damage to your critical process assets.

WEX Heating Jackets

Heating Jackets & Mats for Hazardous Areas

Hazardous area heating jackets and mats are specialised heating systems engineered for use in potentially explosive environments, such as those found in the chemical, petrochemical, and pharmaceutical industries. Certified in accordance with ATEX guidelines, these solutions ensure maximum safety and reliability in hazardous zones.

Designed to deliver uniform heat distribution, these heating jackets and mats are essential for eliminating cold spots and maintaining consistent process temperatures. Their flexible construction allows them to be easily adapted to different surfaces, vessel shapes, and equipment geometries, highlighting their versatility and efficiency in demanding industrial applications.
