Energy efficiency in yeast production

25 October, 2016

The final endorsement of the new installation was voiced by Houghton: “We have found that the Atlas Copco units cope with the essential fluctuations in process air demand, and it seems that screw blower technology can operate from 100% capacity down to 25% with very little change in specific power requirement. We estimate that our energy costs are down by at least 25% and at this rate we expect to achieve payback in less than three years.”

Close-tolerance screw elements

Technically advanced screw technology is at the heart of Atlas Copco’s ZS+ blowers - state-of-the-art, close-tolerance screw elements that incorporate years of experience and innovation to deliver 100% pulsation-free and oil-free air that complies with ISO 8573-1 Class 0 (2010) certification. What’s more, an integrated gearbox means better transmission of power from the motor to the compression elements. There is no requirement for belt and pulley replacement, and the concept is designed for reduced maintenance costs and increased uptime.

Elektronikon operating system

All the ZS+ blowers are complete with an Elektronikon operating system to provide control, to monitor the overall system performance status, and to increase the blowers’ efficiency and reliability. In addition, a Mk5 Gateway interface box, operating with software developed by Lallemand GB’s parent company in Canada, allows the compressors to be speed controlled and the compressor data to be visualised on the site’s management system.
