ZLC  Two-Stage Multi-Function Vacuum Oil Purifier Series
ZLC Series can deeply and quickly purify insulating oil of all kinds of electrical equipments, it's produced higher than national standard and can quickly remove water, gases, particles from contaminated/waste oil, improve dielectric strength, shorten period of oil treatment

Application
This machine is widely used in all industry such as power plants, power stations, power companies, metallurgy, petrifaction, machinery, traffic, railways etc. Especially for on site transformer overhauling with 110 KV or over, drastically remove poisonous gases such as firedamp from new oil or imported oil. It's equipped with one special device for additives, which is easy to operate; the additives put into the device is innocuous. The process of depolarization is a physical process and never destroys oil quality, the oil after treatment will up to international standard.
Features:
1) Just one single pass the breakdown voltage can improve to 45 KV, after three passes the breakdown voltage will get to 75KV, reduce the degree of aging which is from common oil purifier.
2) High speed two- stage vacuum system can vacuities for transformer's on site installation or overhauling, finish removing gases, water, discolor simultaneously, shorten period of oil treatment.
3) Unique degas, dehydration, depolarization system, adopt stereo-evaporation technology, high efficiently remove water, gases, impurities from transformer oil, improve oil quality and dielectric strength.
4) Fine filtration system, five- layer agglomeration filtration from Japan, and super high fine filtration from USA, in combination with several stages of screens with mesh size reduced stage by stage. The filtration precision gets to international standard; NAS 4 Class .The life of filtration is more than one year.
5) Excellent configure; Main fittings from USA, Germany, France, Italy, etc and electrical system imported with original packing, ensure this machine can run safely with high performance and can continuously run about 720 hours.
6) This machine has interlock protector: A. outlet oil can reflux through overflow valve. B. Oil inlet and heater work simultaneously to avoid failure from incorrect operation.
7) High autoimmunization: adopt PLC full automatic system, operate by touching screen, with dynamic display and can connect computer to operate.
8) Advanced infrared liquid-level automatic control system to accomplish fully automatic control.
9) Special oil pumps design and lower noise.
10) Special additives for depolarization, can recover oil color of aged transformer oil to close to new oil color, equipped with flexible unloading device of short time, good efficiency, small quantity. Discolor under vacuum can save cost of treatment, the waste impurities does not pollute environment (it can be used to architecture and pave a road).
