The double-stage vacuum transformer oil filtration machine provides deep dehydration and degassing of insulating oil. GlobeCore offers CMM-6 and CMM-10 dual-stage systems. We will send a quotation upon confirmation of voltage and capacity requirements.

When selecting a double-stage vacuum transformer oil filtration machine, practical aspects such as mobility, ease of installation, and accessibility at the location of operation can be just as important as the actual purification performance. Power utilities and maintenance contractors often need to service transformers at different substations, where compact dimensions and rapid commissioning help minimize downtime and simplify logistics. A mobile unit also allows oil treatment to be carried out on site, eliminating the need to transport oil to a separate processing facility.
The photo below shows a CMMur-1L mobile oil plant, illustrating a compact field solution for transformer oil purification. Its mobile configuration makes it well suited for routine maintenance, emergency response, and servicing of transformers at the locations where portability and rapid deployment are essential.

You’re right to prioritize mobility, compact dimensions, and fast commissioning—those factors directly reduce downtime and logistic costs when servicing multiple substations. For truly portable on‑site work consider the smaller CMM family mobile units (for example the compact 1 m3/h class unit) when you need a hand‑carryable solution with two‑stage vacuum dehydration, selectable filtration down to submicron levels, and integrated oil heating; step up to 6–8 m3/h class mobile units when you need higher throughput without giving up maneuverability. If transformer evacuation is required, select a model that includes evacuation capability (some mobile units combine vacuum dehydration and blower/booster vacuum stages) and plan for an exhaust/vent line when operating pumps indoors.

To prepare an accurate quotation, tell me the required processing rate (m3/h), desired filtration fineness (µm) and final dielectric strength target (BDV), site voltage and phase, whether transformer evacuation/dry‑out is needed, expected contamination type (water, sludge, PCB concern), and any transport or access limits (door height, truck mount). Also note if you need extras such as a trailer/chassis, onboard fuel generator, ATEX-rated components, or fast‑connect hoses and fittings—those affect weight, dimensions, and commissioning time and I’ll include them in the quote.
