Providing suitable models for different fields has been our consistent policy. Therefore, if you need a detailed introduction of the model in your industry, please consult our company's business personnel.
Low temperature vacuum distillation system
The varnish is the product formed by the degradation of the oil. Under certain chemical conditions and temperature, it exists in the oil in a dissolved or suspended state. When the paint film exceeds the solubility of the lubricant, the varnish will precipitate and adhere to the components.

1. Quickly absorbs the degradation products of lubricants in a dissolved and suspended state measured by MPC or QSA® test
2. Reduces varnish potential in large gas turbines
3. Operates at normal turbine operating conditions, thus eliminating the varnish deposition cycle that typically occurs during turbine shut down when the oil cools.
4. Quickly reduces and prevents servo valve sticking.
5. Reduces ISO particle-counts.
6. Small footprint and straight-forward operation.
7. DICRTM cartridges are changed annually when installed on common sized reservoirs and used in maintenance mode.
8. Low maintenance, online operation.
Electrostatic Absorption Resolves Insoluble Sludge/Varnish
WJDTM technology is able to remove insoluble contaminations during degradation processes as soon as possible. Experimental results show that Electrostatic Absorption technology absorbs hard and soft pollutants through the flow of particles with charge during oil circulation, preventing your system away from the pollution of varnish and sludge. Compared to several of the competing technologies, WSD WJDTM technology can at least increase the rate of removing the sludge/varnish by 200%.
Removal of dissolved colloids by ion exchange resin adsorption
The degradation products that form the varnish will exist in the oil in the suspended or dissolved state. The electrostatic adsorption technology mainly aims at the degradation products in the suspended state, but the degradation products in the dissolved state should not be removed by the electrostatic adsorption equipment. WSD can continuously and selectively remove the degradation products in the dissolving state by using special ion exchange resin. The resin contains billions of polar sites, which can adsorb the degradation products in the dissolving state. This adsorption depends on the interaction between the polar varnish molecules and the priority molecules existing in the resin, just like the polar varnish prefers to be on the polar metal surface as coating, it also prefers to be adsorbed on the polar part of the resin.
