ZYD is special for filtering the used andold transformer oil, mutual oil, switch oil. Comparing with the single-stagetype, this machine adopts the double stages vacuum system, which can improve themachine's working vacuum value highly, so it can dewater, degas and remove theimpurity more deeply and effectively. The dielectric value of treated oil ishigher than 75KV. It is very suitable for the large electric & insulationequipments.

Feature:
1. High vacuum: Highpoint-Vacuum≤5pa Working-vacuum≤35pa
2. High absorption speed: Absorptionspeed power≥333L/Sr.
3. Duplex 3D stereo-evaporation, eliminating the liquidwat er quickly
4. Distinctive removing impurity system which filters theimpurity through double FH trapezoidal network and absorbs the impurity by highpolymer without the mechanical power.
5. Carbon fiber infrared heatingsystem that can have the oil contain zero sum of ethyne after the treatment.
6. Especially applied to vacuum filling oil and drying for powertransmission equipments which power are over 110KV.
7. Any insulating oil canbe treated on-line at the working site.

Advantage:
Comparing with the single-stage vacuum oilpurifier, this machine dewater, degas and removes the impurities more quickly,more completely, and makes the oils limiting voltage-withstand value muchhigher. As the bridge-type vacuum linking system that can purify and also can bean independent vacuum power supply, this machine can treat the electricinsulation devices.
