ENER-JET Steam Ejector Hybrid Vacuum Systems
Steam Jet Ejectors Combine with Liquid Ring Pumps to Deliver Deep Vacuum and Optimize Efficiency
Since 1979, Nash has manufactured the most efficient, reliable hybrid vacuum systems. The NASH ENER-JET Hybrid Vacuum System combines the stability of our liquid ring pumps with the high vacuum capabilities of our steam jet ejectors resulting in a hybrid vacuum system that reduces GHG emissions and operating costs while improving system stability. Hybrid systems can be used in any industry or application where deep vacuum is required like chemical, electrical power, oil & gas, and pharmaceutical industries.
With their ability to handle increased back pressure, operate in on/off design conditions, and tolerate fluctuating cooling water temperatures in system inter-condensers, hybrid systems make for more stable and reliable alternatives to all ejector systems for crude vacuum tower applications.
With an innovative design that reduces steam consumption up to 15%, compared to previous Nash ejector design, an ENER-JET hybrid vacuum system can pay for itself in two years or less due to energy savings. In addition to potential cost savings, such an installation can also reduce greenhouse gas emissions. Two stage hybrid system can further lower installation costs by draining the condensate from inter-condenser into the liquid ring vacuum pump.
Designed to operate in harsh conditions
Hybrid systems can be used in any industry or application where deep vacuum is required like chemical, electrical power, oil & gas, and pharmaceutical industries. All existing ejector systems can be optimized and converted to hybrid systems where there is insufficient steam in the plant. Process and application knowledge are key to selecting the correct combination of technologies for an effective hybrid system. To determine the best combination for a particular application, design engineers must be experts in multiple technologies and also understand the equipment limitations of each technology being combined.
Optimizable based on specifications
Our hybrid vacuum systems can be optimized in a variety of ways based on initial cost, payback period, or utility limitations. Our experience team of application engineers can optimize a hybrid system specific to your process, application, and technology requirements to deliver maximum efficiency and performance benefits.
All NASH Hybrid Vacuum Systems are 100% performance tested prior to shipment and are backed by our manufacturer’s warranty.
