Liquid explosion-proof electric heaters are mainly used for heating objects such as acid and alkali, chemical reagents, water, oil, etc., mainly made of stainless steel as surface metal sheathing materials, such as: 304, 316 stainless steel, etc., with mechanical strength. High, heat resistant, corrosion resistant, and less prone to scale.
Liquid explosion-proof electric heater technical indicators:
1. Power deviation: +5~ -10%
2. Cold insulation resistance: ≥50MΩ3. Insulation withstand voltage: 200V working voltage is 1500V/1min 380V working voltage is 2000V/1min
