Thanks to its experience in the Atex (Explosive Atmosphere) sector on electric heaters and to the product certification obtained at the Cesi in Milan, Reart produces Electric heaters on flange in Exd execution, for heating liquids and gases of all kinds for the plant sector, Chemical and Petrochemical in a potentially explosive environment (Zone 1 & 2).
The Atex-ex execution flange heaters are studied and designed to fix the electric heater to the process to be heated, through a special connection flange that is defined according to the UNI or ANSI 16.5 standards. Unlike the process connection flanges, they can be designed and built according to customer specifications or requirements.
This type of heater is used for heating fluids in:
The electric flange immersion heaters are suitable for heating all non-corrosive process fluids. They consist of one or more U-bent heating elements welded to the main connection flange by TIG welding, complete with electrical connections, safety devices and relative protection casing.
All the heating elements welded to the main flange of the heater are tested through hydraulic tests at well-defined pressures according to the design conditions indicated by the customer.
Thanks to the hydraulic test performed by Reart on the welded heater, it is possible to guarantee the tightness of the welds of the heating elements to the flange, declaring this test in the final test certificate issued together with the product and issued by Reart.
General technical characteristics of the Flanged Electric Heaters in Ex execution.
The flange Electric heating elements in Exd execution are essentially composed of:
The connection flange of the electric heater is defined and sized according to the customer already in the offer phase, so that the heater can be sized according to process data.
The design for this type of heater is carried out according to the functional data requested by the customer, and also considering and evaluating dimensional, physical, chemical and thermodynamic characteristics of the fluid to be heated, so as to guarantee a very precise and accurate choice of the sizing of the heater and building materials. The size of the flange depends on the electrical conditions imposed by the regulations for Atex execution.
The electrical power installed on Atex flanged electric heaters can vary up to thousands of kW with the aid of settings according to customer specifications, Reart engineering and reference standards for the sizing of heaters in Exd execution.
Usually, we can have the following reference design parameters for the sizing of the flange electric heaters:
All electric flange heaters in Atex execution are equipped with thermal sensors such as thermostats and/or thermocouples or temperature probes (PT100) to protect the system and the heater itself in the event of abnormal or unexpected situations on the system.
Atex flanged heaters can be equipped with the following accessories:
