The open coil electric heating element made by Jaye industry adopts the structure of without outer metal tube jacket, and no need the MgO powder insulation heat conduction filling layer, but to directly heat the flowing air with the coiling heating wire. Rated voltage of exposed electric heating element: 110v-400V and rated power: 1kW ~ 50kW; maximum working temperature: 700. C. The heating medium is air, and the thermal efficiency (efficiency rate) is 1-2% higher than that of conventional electric heating elements.
This Open type coil heating element is mainly used on air conditioner, especially on the commercial air conditioner. When the ambient temperature is too low and the heat generated by the air conditioning unit does not meet the predetermined requirements, it is necessary to install an auxiliary electric heater at the end of the unit to make up for the insufficient heat.
A fin-type electric heating element or a spiral or coil-shaped resistance wire is installed on the fixing frame, and a temperature control device, a fuse wire and other control elements are installed. It can be heated by connecting the power supply, and has high thermal efficiency, uniform heating, good heat dissipation, long service life, safe and reliable.
