Air Jets Combine with Liquid Ring Pumps to Deliver Deep Vacuum when Steam is Not Available

NASH Air Ejector Hybrid systems combine the low maintenance technology of air jets with the proven reliability of liquid ring vacuum pumps to deliver deep vacuum for low flow applications such as deaeration, offshore platforms, and condenser exhausting where steam is not available or undesirable.

Description

Our air ejectors operate on proven jet pump principles using atmospheric air as motive medium. Pressurized air or other non-condensable gases can also be used to make the system more efficient by using a smaller vacuum pump. Air has less energy than steam, so an air jet uses approximately 2.3 times more air than the equivalent steam jet's use of steam for the same motive pressure and compression ratio. These systems are recommended when a liquid ring vacuum pump cannot achieve the vacuum level desired due to vapor pressure limitations of ring liquid technology.

Reliable and Low Maintenance

Air Ejectors have no moving parts, making them a low maintenance addition to the liquid ring vacuum system. Our extensive expertise and a large portfolio of liquid ring vacuum pumps allow us to optimize Air Ejector Hybrid Systems of all sizes to deliver the reliable and low maintenance operation you expect from Nash.

Designed to operate in demanding environments

Designed to operate in demanding fields like deaeration towers on offshore platforms, these hybrid vacuum systems offer durability and reliability.

All NASH Hybrid Vacuum Systems are 100% performance tested prior to shipment and are backed by our manufacturer’s warranty.
