VFD Series double stage high-efficient vacuum oil purifier is to remove free and dissolved water, gases, and mechanical impurities from insulating oils so as to ensure its purity and improve its insulation property. It is suitable for the application to oil treatment 500KV super-voltage transforming equipment and 220KV transformer. It is also suitable for the treatment of capacitor oil, transformer oil and freezer oil.
1. Multi-stage precise filtration system with gradually increasing precision, which can effectively remove mechanical impurities from oil.
2. Automatic double-infrared liquid level controller, pressure protector, which ensure long-term safely and reliable operation.
3. Automatic defoaming system with dual electronic monitoring system, which avoid the foam ejecting and gushing to vacuum pump.
4. Advanced cooling system of vacuum pump, it reduces the frequency of oil’s replacement and extends the life of vacuum pump.
5. Interlocked protective system connects 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.
15. Online oil treatment, vacuum drying and vacuum oil-filling for electric equipments.
