REXON Frame Typed Double Stage High Vacuum Insulating Oil Filtration Unit

The REXON ZYD Series Double Stage High Vacuum Insulation Oil Filtration Unit is widely applied in power generation plants, substations, transmission and distribution networks, and industrial power systems where high-voltage oil-filled electrical equipment is in continuous operation. It is especially suitable for on-site maintenance and commissioning of large transformers, mutual transformers, switchgear, and other insulation systems that require strict control of oil moisture, gas content, and cleanliness. The machine ensures that insulating oil meets international standards for dielectric strength and cleanliness, helping to maintain stable and reliable power supply.

In addition, it can be used during transformer installation, overhaul, and preventive maintenance, as well as for oil circulation purification during long-term operation. Thanks to its double-stage vacuum system, it is capable of handling the insulating, even under demanding working conditions such as high humidity or continuous operation environments. By restoring oil quality and extending oil service life, the ZYD series significantly reduces equipment failure risks, maintenance costs, and unplanned downtime for electric and industrial users worldwide.

1. It has a two-stage high-speed vacuum system and a multi-stage vacuum analysis separation system, which can quickly remove moisture, gas, impurities, polar substances and other degraded substances from the oil.

2. The three-dimensional flash dehydration and degassing technology is adopted to efficiently remove water and gas from the oil, so that the breakdown voltage can be rapidly increased to more than 70KV.

3. The effect of one-time filtration is greatly improved, which reduces the risk of oil aging caused by repeated filtration and heating in general oil purifiers.

4. Using the independent dual-channel technology of complex oil and gas, the secondary re-dissolution technology in the separation of oil and gas can be used to quickly remove various organic hydrocarbon gases in the oil, ensuring that the content of acetylene and hydrogen in the oil is zero.

5. Heating by carbon fiber infrared heating system which is the most advanced heating technology, the unique heater structure heats the oil uniformly and easily controlled, it gives out the heat quickly (in 3 seconds after power on) and efficiency of electricity transforming to heat is very high (more than 98%). High efficiency, low density heating method for oil, which can prevent oil cracking at high temperature.

6. The use of a multi-stage high β-value compound progressive and high precision filtration system can effectively filter the 1-micron fine particles of mechanical impurities in the oil.

7. Online oil filtering, unattended operation, vacuum oiling of transformers, etc.

8. Advanced liquid level automatic control system, automatic defoaming control system, pressure protection system and safety interlock control ensure long-term, safe and reliable operation of the equipment.

REXON Unique PLC Fully Automatic Control System

All REXON machines are equipped with our unique PLC electric control program. With one-touch start and stop, the operation is simple and highly efficient. A large PLC display screen clearly shows real-time operating status and system parameters. In addition, the fully automatic control system includes a misoperation prevention function. If incorrect operation occurs, the system automatically locks the process, triggers an alarm, and displays the fault location on the screen, helping operators quickly identify and solve the problem while ensuring safe operation.
