Zhongneng - Model 3000LPH -Double Stage Vacuum Transformer Oil Treatment Machine

1. Effiecient vacuum dehydration system, composed by Leybold brand vacuum pump and reliable Roots pump to achieve stable high vacuum degree, which provide a sound working condition for vacuum dehydration.
2. Adopt 3GR series screw oil pump, lower noise and ensure oil output efficiency when the machine work at high vacuum condition -0.098MPa.
3. After purification, the moisture content is less than 3PPM; oil breakdown voltage is more than 75KV.

Comparing with the single-stage vacuum oil purifier, this machine adds ROOTS vacuum system, second stage of separating system to improve the effect of purification which dewater, degas and removes the impurities more quickly, more completely, and makes the oils limiting voltage-withstand value much higher. As the bridge-type vacuum linking system that can purify and also can be an independent vacuum power supply, this machine can treat the electric insulation devices.
