Roof Enclosed Type Double Stage High Vacuum Transformer Oil Filter Machine

Roof Enclosed Type Double Stage High Vacuum Transformer Oil Filter Machine is equipped with our newly designed roof type weather-proof & dust-proof enclosure. It is designed for transformer oil filtration & transformer vacuum pumping of various on-site projects of power transmission and generation stations. It can remove trace water, gas and impurities from insulating dielectric oil/transformer oil, improving the insulating oil performance index, very suited for purification for high voltage insulating oil of 110KV, 220KV, 500KV, 750KV, 1000KV from power transmission equipment.

This machine is made up of ultra-strong vacuum system (one rotary vane vacuum pump and one roots pump/air compressor), electronic control system, PLC program, constant temperature heating system, three high precision filtration system, oil high and low liquid level detection indicator, vacuum degree detection indicator, automatic defoaming device, alarm system, automatic protection system, etc.

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 multi-stage high β-value compound progressive filtration system can effectively filter the 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.

Double-Stage Vacuum Technology

The REXON ZYD series adopts advanced double-stage vacuum technology to create an extremely high-vacuum, low-pressure environment inside the vacuum chamber. This allows moisture in transformer oil to vaporize at a much lower temperature, while dissolved gases are efficiently released and removed.

Multi-Stage High-Precision Filtration System

ZYD transformer oil purifiers are equipped with a multi-stage filtration system designed to remove solid contaminants thoroughly. The oil passes through primary, secondary, and fine filters with filtration accuracy down to 1–5 microns.

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.

Professional After-Sales Service from REXON

REXON provides customized operation manuals and detailed operation videos for each machine, making learning and operation easy even for first-time users. More importantly, we offer lifetime after-sales support. Whenever you have technical questions or need assistance, our professional team is always available to provide timely support, ensuring long-term stable operation of your equipment and complete peace of mind.
