Project Background

At Tnuva’s Rehovot facility, the existing compressor room operated with several aging centrifugal compressors. These outdated units could not adapt to the plant’s fluctuating air demands, resulting in significant energy waste, high maintenance costs, and limited operational flexibility.

Project Challenges

Implementing an advanced solution that meets the plant’s variable air consumption
Reducing energy usage while ensuring high system availability
Providing a long-term, reliable and efficient solution

What is the solution that we have developed for the costumer?

Our team designed and implemented a cutting-edge upgrade to the compressor system:

Replaced all old compressors with a single ZR500 VSD oil-free compressor from Atlas Copco
Equipped with a 500 kW motor and Variable Speed Drive (VSD) technology to precisely match real-time air demand
Integrated a smart control system for performance monitoring, energy optimization, and predictive maintenance

Advantages of the solution

- Significant energy savings through dynamic load adjustment
- High system reliability with reduced maintenance and fewer breakdowns
- Space optimization by replacing multiple compressors with one powerful and flexible unit
- Smart monitoring provides real-time insights for the maintenance team
Conclusion

By transitioning to the ZR500 VSD compressor, Tnuva successfully upgraded its compressed air infrastructure to a modern, energy-efficient, and high-performance system—ready to support the plant’s evolving needs for years to come.
