ASSEN INSULATING OIL PURIFICATION machine 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. Water, gas, particles and other harmful things will contaminate dielectric strength and insulating performance of transformer oil. Series ZYD insulating oil purification machine combines with unique and advanced vacuum dewatering, degassing components and three grades filtering system for rapidly and effectively separating water, gas, particles from oil. ZYD insulating oil purification machine also can purify switch oil, mutual inductor oil, cable oil, circuit breaker oil, capacitor oil, insulating oil and so on. This transformer oil filter machine is the most effective, durable, and user-friendly Hi-Vacuum system on the market today.

• Based on the high efficient vacuum oil filtration, roots vacuum booster system and secondary high vacuum separation system are added. Which enable the vacuum limit reaching ≤5pa.
• Being able to remove water and gas and effectively under high vacuum and high speed operation status ,which achieves satisfactory dryness and could bring the breakdown voltage up to reduces the oil aging problem existing with ordinary purifier as caused by repeated heating.
• Distinctive removing impurities technology filtering through double FH trapezoidal network and absorbing by high polymer without the mechanical power.
• The advanced infrared level automatic control system. interlocking control foe pressure protection and power heating system ensure long-term safe and reliable operation.
• Mobile equipment for outdoor use.
• Live-line vacuum oiling and dehydrating feasible.

• Transformer is one of the main asset in the electrical power industry which needs to be maintained for guaranteed uninterrupted power transmission in order to get assured revenue benefits.
• Transformer life mainly depends on the quality of oil volume it contains.
• Transformer oil conditioning may also include to some extent improving the acidity of the oil.
• A good oil purification system is able to deliver filtered oil with parameters as per the standard specification.

low temperature distillation used transformer oil filter machine Technical Data:

Structure Chart:

The oil technical data after treatment:

• Gas content less than 0.1%
• Impurity size less than 1μm without free carbon
• Oil dielectric strength (breakdown voltage) more than 75KV
• Acidity value less than 0.01 mgKOH/g
• Dielectric loss factors at 90°C less than 0.001

low temperature distillation used transformer oil filter machine Advantage:
  Comparing with the single-stage type, this series adopts the double-stages vacuum system, which immensely raises the machine's working vacuum degree, so it can dewater, degas and remove particulate impurities much more efficiently. It allows the transformer to be in service while impurities are effectively removed.

Q: How can we achieve drying without elevated heating of the insulation material for transformers?
A: Drying of insulation materials can be achieved at low temperature and low pressure levels. The pressure levels and temperature levels for drying vary for distinct material. At low pressure or under vacuum the rate of water vapour evaporation is accelerated if sufficient heat is provided to the insulation material. Thus we can achieve a good drying of insulating material if the material is suitably heated and subjected to vacuum.
