ATEX Heated Storage Container

A turnkey hazardous area heating solution for safe chemical storage – from concept to completion

Thorne & Derrick delivered a fully bespoke ATEX certified heated storage container to a multinational biotechnology company, enhancing safe, compliant, and energy-efficient heated chemical storage in a hazardous environment. This complex and fully compliant solution replaced an outdated boiler system.

Solution Development

Through proactive outreach, Thorne & Derrick engaged with the client, leading to a site visit to assess the situation. Recognising the client’s need for a modern electrical solution, Thorne & Derrick spearheaded the design and delivery of a fully bespoke heated storage container. Thorne & Derrick worked together with several supply chain partners to design and deliver a temperature controlled storage unit including the use of latest fan heater technology from EXHEAT.

The client required a container with a capacity of 48 barrels or 12 IBCs. The challenge was to provide a controlled heating solution that could heat up and maintain ambient temperatures as per the chemical manufacturers guidelines.

Compliance & Testing

A full Factory Acceptance Test (FAT) was conducted, with the client’s engineers attending site to inspect and sign off the solution prior to delivery. This ensured full satisfaction with the build quality, safety features, and operational readiness.

Technical Highlights

• EXHEAT LFH Fan Heater
• Custom Temperature Control Panel 
• ATEX/IECEx certified components throughout
• Designed for safe temperature control storage of up to 50 different chemicals

Product Focus

A critical component of the build, the EXHEAT LFH was selected as the only ATEX-certified fan heater on the market approved for use with rigid front and rear ducting. This unique design was essential in satisfying the client’s strict safety requirements for hazardous area operation. The LFH enabled safe, controlled warm air distribution within the container, while its robust, compact design and proven reliability made it the optimal choice for this application.

The heater has a built in safety features including an automatic over-temperature cut out. Additionally ambient temperature control for low and high temperature alarms was built into the control system. Further the system was designed for the fan to run constantly and ensure even air circulation and thermal consistency. To maximise space internally the heater was fitted to the rear of the container which also provided easy access for maintenance.
