1. The outer diameter of the main technical parameters:? 3.0MM; 4.0MM; 5.0MM; 6.0MM; 8.0MM; 10.0MM; 12.0MM; 16.0 MM 20.0MM; 25.0MM; 27.0MM?????????? ; 30MM (press the power ratio is reasonable calculation) 2. Operating voltage:? 55V, 110V, 220V, 380V 3. Working temperature: 900 ℃ 4. heat pipes: USU304 310S stainless steel GH3030 5. Insulation resistance: more than 50MΩ (1000VDC) 6 The power: 0.5KW-10KW every single branch Product Features 1: Baking uniform: because the heater flexible, so you can even clouds in a vacuum chamber, which could be surrounded by geometric state, avoiding dead heat baking to ensure even temperature of 2: clean: vacuum sealed stainless steel heater exterior protection at high temperatures without any long-term pollution. 3: No ignition: vacuum heater in working condition no current through the surface, there is no overall electrical connectors and stainless steel table adjacent screen to avoid the body plays a role in the coating process, there is no arc discharge of contaminated glass phenomenon. 4: Long life: vacuum heater uses a special material and technology, coupled with the control system can reach more than three years.
