An emergency safety shower is used to provide immediate assistance to people who have come into contact with corrosive substances, chemicals, or have suffered burn injuries. It is therefore essential that the emergency shower is always available at the correct water temperature. If this is not the case, it may have adverse consequences for the user. In an ATEX environment, the use of an emergency shower is even more critical, and the heating system must be adapted accordingly. At Heating Group International, we are happy to explain how an Ex flange heater can be applied to an emergency shower installation in a hazardous ATEX area.
An emergency shower must be operational at all times. If it is not, this can have serious consequences for the user. When the water in a storage tank, buffer vessel, reservoir, or piping system becomes too cold or freezes, it can affect both the water flow and the water temperature. Maintaining the water at a predetermined temperature is therefore essential to ensure the emergency shower is always ready for use when needed.
A flange heater can be used to directly heat the buffer tank, reservoir, or storage tank connected to the emergency shower system. One of the main advantages of a flange heater is that it can be installed directly inside the tank. This provides efficient and direct heat transfer, ensuring uniform heat distribution throughout the application.
In an ATEX environment, a standard flange heater is not suitable. Every heater is calculated and engineered specifically for the application so that it complies with the relevant ATEX requirements. Hazardous areas are often divided into multiple zones, and the flange heater is designed and manufactured according to the designated ATEX zone.
Our flange heaters can be used in Zones 1 and 2. They are also suitable for gas groups IIA, IIB, and IIC, and for temperature classes T1 through T6. ATEX flange heaters are not standard heating elements. They are custom-made based on the specified ATEX zone and the associated temperature and gas group requirements.
Our tip: Based solely on the application and dimensions, we are often unable to determine which ATEX zone applies to the heater you require. If you have an enquiry for ATEX-certified heating, please provide the applicable ATEX zone and the associated requirements. This enables us to assist you more quickly and accurately with the right heating solution.
Flange heaters can be used for both small and large storage tanks, as they are available in a wide range of sizes from DN40 to DN500. The material used for the flange heater depends on the medium being heated and the required ATEX classification. Common materials include stainless steel, Incoloy 800, and Incoloy 925. The terminal enclosure can be manufactured from cast iron, steel, or stainless steel, depending on the ATEX requirements of the application.
For many emergency shower installations, temperature control is almost as important as the heating itself. The water must remain within a specified temperature range at all times. An ATEX flange heater can be controlled remotely through a dedicated control panel. This allows the user to set or adjust the temperature while also providing protection functions for the system. The control panel itself can be supplied in an ATEX-certified version that complies with the requirements of your hazardous area application.
Standard electric heating equipment is generally not suitable for hazardous ATEX environments. If you are looking for the right heating solution for your ATEX application or have questions about an ATEX flange heater, please feel free to contact us. Our specialists will be happy to help you select the most suitable ATEX heating solution.
