The Atex-Ex flanged heaters produced by REART are designed to ensure maximum safety when heating liquids and gases in potentially explosive environments, such as Zone 1 and Zone 2.
REART’s expertise in the Atex (Explosive Atmosphere) sector and its product certification obtained from Cesi Milan guarantees the precise design of Atex electric heating elements, ensuring safe operation in hazardous atmospheres. These heaters feature highly resistant materials and an optimized architecture for secure installation on tanks, and other industrial applications.
These heaters are designed to be attached to the heating process through a connection flange compliant with UNI or ANSI 16.5 standards. Upon request, connection flanges can be custom-designed and manufactured to meet specific client requirements, ensuring maximum versatility and safety.
The ATEX-Ex electric heaters, designed to meet the essential safety requirements for explosive environments, are used in
Flanged electric heaters are typically used in heating systems for:
Flanged electric heaters with Atex-Ex certification are used in the following reference sectors:
REART’s Atex heating elements are designed to offer high performance and safety. Each unit is made with U-shaped heating elements, TIG welded to the main flange. This design ensures durability, even in the most extreme conditions.
Usually, the following reference design parameters are used for the sizing of the flanged electric heaters:
Exd flanged armoured electric heaters are essentially composed of:
The design process for this type of heater considers not only client-specified functional data but also the dimensional (available space), physical, chemical, and thermodynamic properties of the fluid to be heated. This ensures an accurate selection of heater dimensions and construction materials. The flange size is determined based on the electrical constraints imposed by ATEX regulations.
All flanged electric heaters with Atex certification are equipped with thermal sensors such as thermostats, thermocouples or resistance temperature detectors (PT100) to protect both the system and the heater in case of abnormal or unexpected conditions.
Atex flanged heaters can be equipped with the following accessories:

ATEX-Ex is a certification indicating compliance with the ATEX Directive (Atmosphères Explosibles), which is necessary to ensure safety in potentially explosive atmospheres. ATEX-Ex flanged electric heaters are designed to be safe and reliable in these environments, such as Zones 1 and 2, reducing the risk of fire or explosion.
ATEX-Ex heaters are equipped with thermal sensors such as thermostats, thermocouples, and resistance temperature detectors (PT100), which monitor and regulate temperature to prevent overheating and malfunction. These safety devices are crucial for maintaining safe operation, even in case of operational anomalies.
Yes, REART offers full support for the installation and maintenance of ATEX-Ex electric heaters. A spare parts supply service is also available to ensure long-term performance and reliability.
