ZYD-100 Double Stage Transformer Oil Purification Machine

We are proud to share a remarkable success story from one of our esteemed clients in South Africa. Last year,as a successful transformer maker in South Africa, they purchased the ZYD-100 Double Stage Transformer Oil Purification Machine, and the results have exceeded all expectations.

Now, after months of reliable, high-performance operation, the client has reached out not only to express their full satisfaction but also to place an order for a second ZYD-100 Double Stage Transformer Oil Purification Machine with 2 E+E moisture sensors – this time for on-site transformer installation, oil purification, and after-sales service in the field.

Let’s take a closer look at why this machine has become an indispensable asset in their transformer production line – and soon, in their customer service fleet.

What the ZYD-100 Double Stage Transformer Oil Purification Machine Delivers

The model delivered to South Africa was no standard unit. It was equipped with a carefully selected set of premium components to ensure maximum efficiency, precision, and durability:

• Vacuum Pump: Leybold SV-100B – Reliable, powerful, and energy-efficient, providing a strong foundation for deep vacuum dehydration.
• Roots Pump: Huaxin Blu-Ray ZJP-150 – Enhances the vacuum system to achieve ultra-low pressure levels for faster and more complete removal of moisture and gases.
• Oil Transfer Pump: Italian SEIM SRL (YPXF055) – Known for its smooth operation and long service life in demanding industrial environments.
• Control System: Schneider Electric + Siemens PLC – Seamless automation with precise process control and real-time monitoring.
• Moisture Sensor: Austrian E+E – Accurately reads water content in transformer oil, giving the operator full visibility into machine performance and oil quality.
• Design Highlights: Horizontal vacuum chamber, three-stage filtration system, and a precision heating system – all working together to efficiently remove moisture, gases, and solid particles from transformer oil.

Results That Speak for Themselves

The South African client uses the ZYD-100 Double Stage Transformer Oil Purification Machine primarily in their transformer factory to:

• Purify fresh and used transformer oil
• Inject high-quality, degassed, and dehydrated oil into newly manufactured transformers

Thanks to the real-time moisture readings from the E+E sensor, their quality control team can instantly verify the oil’s dryness and dielectric strength. This level of transparency allows them to trust the process without guesswork – and the results have been consistently outstanding.

After months of daily use, the machine continues to restore transformer oil to well above acceptable dielectric strength levels, effectively protecting their newly built power transformers from internal faults, corrosion, and premature aging.

A Growing Partnership: Second Machine for On-Site Service

Recently, the client contacted us again – not with a complaint or a service request, but with praise and a new requirement.

They were so impressed with the ZYD-100 Double Stage Transformer Oil Purification Machine’s performance in their factory that they now want an identical unit for their field service team. This new machine will be used during:

• On-site transformer installation
• Field oil purification before transformer commissioning
• After-sales maintenance and troubleshooting

In short, they want to bring the same level of oil quality they achieve in their factory directly to their customers’ substations and power sites.

Why They Chose Us Again

When asked why they didn’t look for a lower-cost alternative for their field operations, their procurement manager replied:

Built for the Real World

Whether in a fixed factory environment or a mobile field service truck, the ZYD-100 is designed to perform. Its horizontal vacuum tank ensures stable operation during transport, and the triple-stage filtration system handles variable oil conditions with ease.

For transformer manufacturers and power service companies, this machine offers:

• Accuracy – E+E moisture sensor for real, reliable data
• Reliability – World-class components (Leybold, Siemens, Schneider, S.E.C.)
• Efficiency – Deep vacuum + roots pump for fast processing
• Peace of mind – Restored dielectric strength and clean, dry, degassed oil

Conclusion

It’s one thing to claim a machine is high-performance. It’s another thing entirely when a customer – after a full year of heavy use – returns to say, “We want another one exactly like it, because it simply works.”

We are truly grateful for the trust placed in us by our South African partner, and we look forward to delivering their second ZYD-100 double stage transformer oil purification machine – this time ready for the road, for on-site power transformer service.
