Electrical Transformer Evacuation Project

Our customer is a company that builds massive electrical transformers.  They approached CompreVac to find a faster way to evacuate the transformers at their Regina facility.  Following each build, the transformers need to be evacuated down to 29”Hg.  Once evacuated, the transformer is tested for leaks before being filled with an inert gas or oil.  Their current vacuum system takes far too long to evacuate each transformer. The volumes to be evacuated are massive.The vacuum system built by CompreVac in their Mississauga location will make a huge difference to the vacuum pump-down time.

The system backing pump is a Rietschle VSI Series Rotary Screw vacuum pump , that has its own on-board, sealed-for-life cooling system, (just like a modern car).  This remarkable pump can operate at depths of 29.917”HgV, or 0.075 Torr.  The normal open flow pumping speed of this pump is insufficient to meet the volume requirements of this demanding application.  To increase the volume, we have added a Rietschle VWP-1000 Rotary Lobe Booster.  Unlike similar booster blowers, the VWP has a mechanical by-pass system that automatically closes to permit the full flow of gasses from the transformer.  Once on line, the booster will enable the system to extract gasses at a rate of almost 2,000 cfm, making the challenge of evacuating huge transformers a very quick breeze.
