1. On the basis of vacuum pump, this machine also installs Roots Pump vacuum system, which speed up
evacuation, make limiting vacuum ≤ 5Pa, working vacuum ≤ 35Pa.
2. Large area three-dimensional flash distillation technique, advance dewatering and degassing system, which removes water and gas much quickly and efficiently.
3. Precise and multi-stage filtration system (primary filter, secondary filter, fine filter) with gradually increasing precision, which can effectively remove mechanical impurities from oil.
4. Advanced double-infrared liquid automatic controller, pressure automatic-protector, which ensure long-term safely and reliable operation.
5. All necessary control switch, light indicator and meter are equipped on the control panel which provides easy control for operation and supervision.
6. Adopt interlocked protective system, which connect oil pump, electric heater and oil level controller,
Avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be
power off automatically.
7. High-Efficiency electric heating system, heating oil uniformity, avoid oil deterioration in the process.
8. This machine can be operated both online and offline. Besides, it can be used as independent vacuum
drying or vacuum oil filling equipment for oil-immersed electrical equipment.
9. After purification the transformer oil’s technical parameters and performance are reclaimed, the oil’s breakdown voltage can reach up to 70KV in an ideal condition.
10. In general the machine is mounted on caster. Enclosed type, trailer-mounted, upgrade to Leybold vacuum pump type, equipped with PLC or flow meter etc. are optional.
