Our ZJA Mobile Type 1500L/H Transformer Oil Refining Machine is professional for treatment of transformer oil, it can efficiently remove water, gases, acid, particles, etc. from the oil.
With the advantages of high working vacuum, high filtration speed, oil quality protection, the filter advanced the oil treatment technique and equipment performance and once can raise the puncture voltage up to over 35V.
ZJA Mobile Type 1500L/H Transformer Oil Refining Machine can be installed by sealed regular or movable with a trailer, so it is suitable to treat oil, fill oil in vacuum chamber and circulating dry hot-oil when large transformer is being installed and overhauled.

Imported vacuum-pump from Europe has preceding level in the world and high air pump speed guarantee high working vacuity.
New technology of vacuum-segregating adopts particular spinning disk and stainless steel machine with dehydration and air pump.
Using new type of heating equipment which can reduce heating burthen and extend oil life.
Oil level control adopts photoelectric way of which the main components are imported from Switzerland.
Customers can choose equipment equipped with all or partly imported components.
It's equipped with filter assemblies imported from Italy.
All pumps must be airproofed by our factory, moreover running without noise and leakage. extended oil life.
