What does ATEX stand for? Expand Collapse
ATEX comes from the French “Atmosphères Explosibles” and refers to European rules that equipment can be safely used in explosive environments. ATEX-certified heaters are tested to make sure they don’t spark or get hot enough to ignite gases, vapours, or dust. This certification is essential for safely operating electrical equipment in industries such as oil and gas, chemical processing, and pharmaceuticals. ATEX & IECEx compliance ensures the equipment meets international standards for hazardous and severe-duty locations.
What types of ATEX heaters do you supply? Expand Collapse
At Carlton Technologies, we offer ATEX-certified electric heaters that are safe to use in hazardous environments, including:
  • Flange ATEX Heaters – Fits onto a tank or pipe with a bolted flange, perfect for secure, high-pressure use.
  • Screw ATEX Heaters – Compact, easy-to-install heaters that screw into threaded openings, perfect for smaller vessels or tanks.
Each heater type can be customised to your process requirements, including power rating, materials, voltage, and hazardous area classification.
What fluids and gases can ATEX heaters work with? Expand Collapse
ATEX-approved heaters from Carlton Technologies can safely heat a wide range of substances, including:
  • Water – including fresh, seawater, and hot water applications
  • Oils – crude oil, fuel oil, lubricating oil, and other light and heavy oils
  • Air, nitrogen, and other gases – for process heating or drying applications
  • Steam and heat transfer fluids – including water-glycol solutions and other heat transfer fluids
These heaters are made to match the fluid or gas, considering its thickness, temperature, and chemical makeup. Options include flameproof immersion, indirect heat exchangers, or low-watt density rod/hairpin designs for liquid flow applications. Stainless steel construction is available for enhanced corrosion resistance.
How powerful can ATEX heaters be? Expand Collapse
Carlton Technologies’ ATEX heaters can deliver very high power outputs, up to 1.77 MW per unit. This includes EXHEAT AFT, EXHEAT FP, EXHEAT HB, and EXHEAT HRF models. These heaters are ideal for large industrial processes that require continuous heating, consistent temperatures, and high energy efficiency.
What is ATEX certification, and why is it important? Expand Collapse
ATEX certification confirms that equipment can be used safely in “explosive” atmospheres, such as areas with flammable gases, vapours, or dust. It is a legal requirement in the UK and EU for these types of hazardous areas. Using non-certified equipment could create a serious safety hazard. ATEX & IECEx compliance means these heaters are safe for hazardous areas, including Zone 1 and Zone 2. They provide accurate temperature control and can be safely added to heating systems.
What should I consider when selecting an ATEX heater? Expand Collapse
When choosing an ATEX heater, consider:
  • The type of fluid or gas to be heated
  • Desired operating temperature and process temperature maintenance
  • Flow rate for gases or liquids (liquid flow applications)
  • Operating pressure and vessel design
  • Hazardous area classification and gas group
  • Available installation space and maintenance access
Giving these details helps you choose the right Carlton model for efficient heating while keeping costs low.
What maintenance do ATEX heaters require? Expand Collapse
Routine maintenance keeps ATEX heaters safe and reliable. Typical tasks should include:
  • Inspecting seals, gaskets, and terminals for wear or corrosion
  • Checking control systems, flameproof enclosures, and safety cut-outs
  • Cleaning heating surfaces to prevent overheating or the production of pollutants
  • Verifying insulation resistance and electrical continuity
Regular maintenance reduces downtime, supports process temperature maintenance, and extends heater life. Proper care helps maintain thermal efficiency and safe operation in hazardous and severe-duty locations.
What types of heating systems are available for hazardous areas? Expand Collapse
Carlton Technologies provides a selection of ATEX-certified heating systems designed for safe operation in hazardous areas with explosive atmospheres. These systems include flange-mounted heaters, screw-in heaters, and options for heating liquids, gases, or storage containers. They are suitable for applications that require process temperature maintenance, industrial heating, and safe operation in Zone 1 or Zone 2 classified locations. The systems can be chosen with different power ratings, materials, and control options to suit your process requirements while maintaining compliance with safety standards.
