Productomschrijving
Alumina Seal Ceramic Rings / Industry Insulation Rings
1. Description:
Alumina ceramic heating element vs PTC ceramic heating element
Electric heaters heating constant heat field pipes: Under the same conditions, when a fixed voltage is applied, the air heating effect of MCH electric heaters is better than that of PTC electric heaters.Closed space heating test: In terms of power consumption, MCH saves energy by 24.59% compared to PTC.
Heating silicone oil comparison test: Use silicone oil as the heating and conduction medium to compare the heating performance and power consumption of PTC and MCH heating components. , Under the same conditions as other conditions, the heating effect of MCH heating element heating silicone oil is significantly better than that of PTC heating element under the premise of consuming the same power.
