Open coil heating elements are the most efficient type of electric heating element while also the most economically feasible for most heating applications. Used predominantly in the duct heating industry,they have open circuits that heat air directly from the suspended resistive coils.
These open coil heating elements have fast heat up times that improve efficiency and have been designed for low maintenance and easily, inexpensive replacement parts.
Open Coil Heating Elements are indirect industrial heating solution to decrease watt density requirements or the heat fluxes on the surface area of the pipe connected to the heated section and prevent heat sensitive materials from coking or breaking down.
1. Typical Applications
Industrial Air Heaters – Used in ovens, furnaces, and drying systems.
HVAC & Ventilation – Installed in ducts, air handlers, and heat recovery units.
Process Heating – Preheats combustion air, exhaust gases, or industrial airflow.
2. Installation Guide
Mounting – Secure inside ducts, chambers, or plenums using brackets or flanges.
Airflow Direction – Ensure uniform airflow across coils for optimal efficiency.
Wiring – Connect to thermostats, SCR controllers, or PLCs for temperature regulation.
Safety – Install thermal fuses or airflow sensors to prevent overheating.
FAQ
1. Q:How do I know about the production?
A: We will double confirm your requirements and send you the sample before the mass production.
During the mass production, we will keep you informed of any progress. Besides, we will
do 100% quality inspection before shipment.
2. Q: Is it OK to print my logo on heating element product?
A: Yes. Please inform us formally before our production and confirm the design firstly based on our sample.
3. Q: Can we design our own package or print our own logo?
A: Yes! Package and logo will be made acording to your requirements.
