1.Features:

1) Manufactured as per standards which go beyond the legal criterion. A primary breakdown voltage can raise 35KV and reduces the oil damage causing by normal purifiers due to repeated heating.

2) Large absorption speed double vacuum meets the needs of vacuum zing of transformer on an installation or repair site, at the same time remove the water, gas, and also keep the completeness of transformer oil. It significantly shortens the oil treatment time.

3) The unique gas, water removal system adopting stereo-evaporation technology, which rapidly separates the water and gas in the oil and is free of maintenance.

4) A superior purification system with top quality filter core, which can accommodate large quantity of impurities and is progressively dandified step by step. It has been got a high precision and multi-stage filtration.

5) Imported parts adopt all electric system, which ensures high performance.

6) Advanced infrared liquid level control system with automatic control, allowing separated operation of manual operators from a machine.

7) Interlocked safety protection device. i.e., backflow of A oil outlet over pressure can be achieved via an overflow valve, B oil inlet will interlock with heating system which avoids any possible negative impacts caused by mal-operation

8) Precision oil pumps have low noise and environmental regulatory compliance will be well met.

2. Equipment systems:

(1) Filtration systems: 

Progressive encryption filtration system makes the final cleanliness level of the oil after treatment up to NAS6 (NAS1638) or above.

(2)The heating system:

Heating system consist of the heater, temperature controller, temperature sensors and over-temperature protection components and so on; the oil to be treated go through the heater under the pressure and carry out heat exchange heating, heat load of heating tube surface is 1.5Kw / c ㎡, By heating the flow of oil enhanced and the water in oil keep in boiling, which is good for the next step-- the evaporation of oil. Temperature controller do the real-time monitoring to the heating system and controlling the heater work at a set temperature range to achieve the protection of equipment and personnel safety.

(3) Vacuum system: 

Vacuum system consists of a vacuum separator, vacuum pumps, Roots pumps, condensate cooler parts, etc. vacuum separator with models to match the evaporation unit, thereby enhancing the evaporation area, and ensure the full evaporation of oil. At the same time give full consideration to the design of gas flow characteristics and it is conducive to the rapid gas extracted by the vacuum source. Vacuum pumping with speed capability vapor evaporation, precipitation, is more double than the gas volume, thus ensuring that the oil will not be secondary pollution, at the same time to ensure that the system work in a state of very low pressure.

(4) Condensate and Cooling system:

The system consists of the cooler and storage components. Water vapor and other gases from vacuum separator through the media cooler, in which these humid heat gas and cooler with blocked exchange medium for heat exchange, moist air has been cooler into water (stored in the container ) and dry air, so as to protect the vacuum pump
