product description: Electrical duct heaters are designed for flange mounting in connection with climate control/heat generation and ventilation systems. Special constructions for e.g. grain dryers, process systems, ships and high-temperature duct heaters are made upon request.
MATERIAL
The duct heaters are available as standard in hot-galvanised steel plate, but can be made of other materials, if requested.
EX-PROOF HEATERS
In addition to the duct heaters mentioned in this brochure Sinus Jevi offers a complete program of explosion-proof heaters.
DESCRIPTION
Duct section
Hot-galvanised steel plate spotwelded with a flange.
Terminal box
Integrated in the duct section and fitted with cable glands.Electric supply through the fitted clamps. Please see
connection diagram and instructions.
Proofing is IP44 other proofings can be made, if required.
Heating elements
Tubular heating elements made of AISI 304 (stainless) with a surface load of 2.5 W/cm² for air velocities above 2 m/sec. For air velocities below 2 m/sec a low surface load is used.
For high-temperature elements (max 800°C tubular cap temperature) AISI 309/Inconell (stainless) is used as tubular material. The heating elements are fitted with M14 brass plugs.
Overheating Protection
In the terminal box there is a built-in thermolimiter featuring automatic reset and a fire thermostat with manuel reset. These must be connected to the temperature control.
Temperature Regulation
It is recommended to use a multistep control device, e.g. Sinus Jevi’s control featuring binary step control. However, duct
heaters below 16.5 kW can be controlled by an electronic control.
Contact Sinus Jevi’s technical department if you have special demands.
