Product Feature 1. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value less than 5Pa. 2. Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly. 3. Double-horizontal film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from insulating oil. 4. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies. 5. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable. 6. Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely. 7. Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be power off automatically. 8. Functions of live line work onsite, vacuum drying and vacuum oiling.
