ZJA10

10000LPH High Vacuum Transformer Oil Dehydration Machine

The ZJA10 10000 LPH High Vacuum Transformer Oil Dehydration Machine is designed for efficient removal of moisture, dissolved gases, and solid particles from new and used transformer oil.
With a 10,000 L/h processing capacity, high-vacuum dehydration, degassing, and 1 μm precision filtration, the system helps restore the dielectric performance of insulating oil and reduce the risk of moisture-related insulation problems.
It is suitable for transformer maintenance, oil treatment, oil filling, and continuous purification applications.

Specification of 10000LPH Transformer Oil Dehydration Machine

10000LPH transformer oil dehydration machine is mainly used to remove moisture, gas, and impurities from the transformer oil.

The 10000LPH transformer oil dehydration machine has the following functions as below:

With a frequency converter, the flow rate can be adjusted by a frequency converter or an oil return valve
Temperature control: The temperature can be adjusted at request
Uses a photoelectric control device to automatically eliminate foam
With an oil level control system to automatically control the oil level
Adopts an over-pressure alarm device, which alarms when the oil discharge pressure ≥0.5MPa
With a protection device for overheating, the heater is not damaged when the oil supply is reduced or interrupted. Heaters can be divided into multiple groups
