ES 2000 explained in one minute
Explained in one minute: the ES 2000 from Energy Support dries and cleans insulating oil online in bypass, without shutting down the transformer. Filter and drying cartridges capture water, particles down to 3 µm and acid residues – residual moisture stabilizes below 5 ppm.

Moisture, particles and acids make insulating oil age – and with it, the entire transformer. The ES 2000 cleans and dries the oil online – during operation, without any shutdown. The unit draws the oil from the lowest point of the transformer. Slowly and at a constant rate, it flows through the filter and drying cartridges. Water, particles down to 3 µm and acid residues are reliably captured. The clean, dry oil flows back into the conservator – and even dissolves old deposits in the tank. Step by step, the entire oil system is cleaned. In practice, residual moisture drops significantly within just a few days – and stabilizes below 5 ppm. A self-priming pump with pressure and leak monitoring and a moisture sensor ensure safe continuous operation. ES 2000. Clean oil care during operation – made in Germany, by Energy Support.

All benefits at a glance
Continuous online drying
Permanent removal of water from the insulating oil in the bypass flow – during operation of the transformer.
Removal of particles
High filter efficiency thanks to long contact time between oil and filter material – filter fineness 3 µm absolute.
Reduction of acid content
In addition to water and particles, the treatment also lowers the acid content and thus protects against oxidation and ageing.
Operation without shutdown
Filtration takes place in the bypass flow, without taking the transformer off the grid.
Pressure & leak monitoring
Self-priming pump incl. pressure and leak monitoring as well as a moisture sensor to indicate the drying level.
Cleaning of the entire oil system
The clean oil dissolves residues already deposited on components and in the tank – cleaning the entire oil system.
