Transformers oil vacuum drying plant ELMO-VSM-3,0
1. GENERAL INFORMATION
Name ELMO-VSM interpretation:
ELMO - means wiring equipment;
VSM - means transformers oil vacuum drying;
3.0 - productivity, m3/h, in vacuum drying and filtration mode;
ELMO-VSM-3,0 plant works from standard 3-phase 4-wire electric network 220/380 V, 50 Hz.
The plant is safe in service, has performance reliability and transportability.
Application of the plant is most effective at treatment of middle-size volumes of transformer oil, where the highest quality of cleaning is required.
2. PURPOSE
The plant ЕLMO- ВСМ- 3,0 is intended for cleaning of fresh and operating transformers and turbine oils from free and constrained moisture, gas, mechanical impurities with viscidity up to 70 mm2/s and maximal temperature 70oC. The plant can be exploited in stationary conditions on foundation or in motion.
