ZYD Series Double-Stage Vacuum Insulating Oil Purifier
The ZYD series double-stage vacuum oil purifier is engineered specifically for the power industry, providing reliable on-site purification of insulating oil for high-voltage transmission and transformation equipment. It serves power plants, substations, utilities and all types of transmission and transformer equipment, and is especially suited to large high-voltage equipment in backbone grids. The unit handles both new-oil filtration for transformers and the purification of insulating oil in service. Whether for on-site equipment installation, scheduled overhaul, or online circulation purification, it is fully capable, effectively shortening the oil-treatment time required for transformer installation and maintenance.
Core Advantage: Efficient Dehydration & Degassing
This is the most critical advantage of the ZYD series - fast, thorough removal of moisture and gases from insulating oil:
Double-Stage Vacuum with 3D Flash Technology
The unit combines a double-stage vacuum system with a multi-stage vacuum separation system and 3D flash dehydration and degassing technology.
Rapid Contaminant Removal & Restored Insulation
It rapidly removes moisture, gases, solid particles and oil degradation products, raises the breakdown voltage of the insulating oil, and restores its dielectric strength-bringing damp, gas-contaminated or particle laden degraded oil back to usable specification.
Advanced Oil Gas Separation
High-efficiency oil gas separation together with anti oil gas redissolution technology quickly strips out dissolved hydrocarbon gases, keeping the insulation condition of electrical equipment stable.
Other Key Advantages
Beyond this core capability, the ZYD series is engineered for dependable, quiet and hassle-free operation.
High Filtration Precision, Low Noise
A multi-stage, high-beta composite filtration system efficiently captures fine particles and all types of contaminants, restoring oil cleanliness. A dedicated precision oil pump keeps operating noise low, meets environmental requirements, and supports long, continuous duty.
Reliable Heating with Anti-Dry-Burning Protection
Carbon-fiber infrared heating, a grouped ultra-low surface-load design, PID constant-temperature control, and dual temperature-and-flow protection ensure dependable heating. An internal enlarged-diameter oil-flow guide with overflow technology eliminates "dead-oil zones," preventing local overheating and dry burning.
Multi-Purpose, Fully Automatic and Safe Operation
The unit supports online insulating-oil filtration without dedicated on-site attendance, and can also perform transformer vacuum oil-filling and hot-oil drying. Multiple control systems are integrated into the machine-automatic liquid-level control, automatic defoaming, pressure protection and safety interlocks-guaranteeing long, safe and reliable operation.
Flexible Configuration for Every Duty
For different duties, the ZYD series is offered in a range of models to cover various flow-rate requirements:
