Electric Duct Heaters

The electric heaters are sized by the technical office, with the help of a software for thermodynamic sizing, thanks to which it is possible to obtain the real operating conditions based on the needs and specifications of the customer to create air flows at a controlled temperature.. Thanks to the use of this software for the sizing of Electric Duct Heaters, it is possible to define the main parameters including:

• electrical power needed
• process side pressure drops
• surface load or specific power
• maximum surface temperature of the heating element
• fluid flow rate inside the coil passage section
• electric heater dimensions
• building materials
• battery condition during normal expected operating conditions

The electric coils, designed to be inserted in conduits with a square or rectangular section, in tubes or packs for ovens, are in direct contact with the process gas to be heated.

In conditions of high temperature, the electrical part of the enclosure is removed from the process to compromise the proper functioning of the electric heater.

All the Electric Duct Heaters supplied are complete with the various safety systems (thermal sensors such as thermostats, thermocouples or temperature probes) to limit high temperatures, in case of anomalous operation of the system, on the process and on the electric heating beam.      

Reco supplies, together with the frame, the connection hoods between the passage section of the battery and the process section of the customer plant. 

The Electric Duct Heaters can be supplied on Skid and with relative electric command and control panel.

The following certification documentation is supplied with the product:
