Customers often ask how much power a Cartridge heater can do. To answer this question, you first need to know what the heating element is for. The Cartridge heater is suitable for heating gas, liquid and solid media. The heat transfer speed of different media is different. Heat transfer rate: solid > liquid > gas, the surface load design is different for different working environments.
First, the use of Cartridge heater and power?
1, size molds and various mechanical equipment plug-in heating
(1) General process: 1-4w/cm2,
(2) Imitation import process: 6-8w/cm2,
2, liquid medium heating
(1) boiling water: 1-8w/cm2, heating element power of 3 kilowatts per meter,
(2) oil heating,
a. Good fluidity: the heating element has a power of 1.5 kilowatts per meter.
b. Semi-solidification, poor fluidity: such as heavy oil, crude oil, etc., the heating element has a power of 300 watts per meter.
3, gas medium heating (air)
(1) Still air: 1-2w/cm2, heating element 1 kW per meter,
(2) Hot air circulation: 1-4w/cm2, heating element 2 kW per metre,
Note: All of the above are Cartridge heater power without over-standard design.
