Vacuum Technologies

In recent years industry has seen a large focus on controlling waste or emissions. 

The Liquid Ring Vacuum pump is still considered the workhorse in the vacuum industry, however it does use water (or other liquid to form the Vacuum seal liquid) and any Liquid waste then needs to be treated.  ESI can design Complete Recirculation Systems reducing such waste.

There are other technologies like "Once Through Oil", however here again the Enduser has to deal with the disposal of contaminated oil.

This is why we see a concerted effort to move towards Dry Vacuum Technology.  The challenge with Dry Vacuum technology are Solids Handling & Liquid carry over.  Many Dry Vaccum designs cannot handle these two common process conditions.  The "SIHI Dry" has build a solid reputation in the industry for meeting these two process challenges.  Click here to see the pump in action.
