The ZYD series double stage vacuum transformer oil purifier is designed for high‑grade transformer oil, super‑voltage oil and newly produced oil. It employs a dual‑vacuum system that can achieve a vacuum level typical of -0.05 to -0.10 MPa, enabling rapid dehydration and degassing of oil on‑site or in a workshop. After treatment, the oil meets a dielectric strength of more than 75 kV and a gas content below 0.1 % by volume.
The unit removes water to less than 3 ppm, acidity to under 0.01 mg KOH g⁻¹ and impurity particles smaller than 1 µm, complying with standard industry limits for transformer oil conditioning. Typical construction features a stainless‑steel pressure vessel and a three‑stage filtration train with a 3 µm filter media, which is a common standard for high‑purity oil applications. Noise emissions are generally within 70‑90 dB(A), and the machine can operate on a 380 V, 50 Hz power supply.
Customers such as transformer manufacturers, utility maintenance contractors and oil re‑conditioning plants use this purifier to extend equipment life and meet regulatory standards. The system can also serve as an independent vacuum source for on‑line oil filling and drying during live‑line substation work above 110 kV. Prospective buyers should request confirmation of minimum order quantities, shipping terms and any required certifications before finalising the purchase.

Sourcing Double Stage Vacuum Transformer Oil Purifier from Chongqing Hopu Filtration Plant Manufacture Co., Ltd - China Import Guide
Importers should first verify the supplier’s manufacturing licence, request a recent third‑party factory audit and obtain the latest type‑test certificates for the vacuum system. Confirm that the machine complies with IEC 60296 for transformer oil and that any optional accessories (e.g., additional filter cartridges) are covered by the supplier’s warranty.
Discuss shipping arrangements early: agree on the Incoterm (such as CIF Shanghai or FOB Chongqing), request an estimated production lead time for the chosen configuration and clarify payment milestones. Because the supplier’s response rate is currently zero, establish a direct point of contact and obtain written confirmation of delivery schedules before issuing a purchase order.
Plan for on‑site quality verification by arranging an independent inspection that checks dimensions, filter integrity, vacuum performance and post‑treatment oil analysis (water, acidity, gas content). Request the original calibration certificates for the vacuum gauges and pressure sensors to ensure the equipment meets the stated technical specifications.
