Features: 1. Low cost and easy operation. 2. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies 3. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable. 4. Double-infrared liquid level sensor, pressure protective system to ensure the machine operation easy and safely. 5. Adopts 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. 6. Working with BZ insulating oil regeneration device to decolorize (remove acid, oxide, free carbon) and lower dielectric loss, making the treated oil more limpidity.
