WATER-INJECTED SCREW COMPRESSORS Atlas Copco’s AQ 15-30VSD water-injected screw compressor, available in water-cooled and air-cooled versions, is designed to meet users’ needs for pure, oil-free air while offering high-pressure capability and improved energy efficiency. Developed especially for applications demanding the highest levels of purity, such as pharmaceutical production, food processing and water treatment, the compressor eliminates the risk of oil contamination with its water-injected screw technology. Zero risk of contaminations — over the past decades Atlas Copco enhanced the development of water-injected screw compressors and today the technology featured in the AQ 15-30VSD removes all the potential for contamination of the compressed air. Water-injected screw technology can completely eliminate the risk of oil contamination in the compressed air and in the condensate. Because there is no oil whatsoever used inside the compressor, there is no waste oil to remove or dispose of. No oil means protection of the environment from oil contamination. Energy efficiency — Atlas Copco AQ 15-30VSD has an integrated variable speed drive claimed to deliver energy savings of up to 35% compared to traditional compressor technologies. It can also help users on their way to sustainability with its energy efficiency, with the proven technology of a water-injected screw element and its certified CLASS 0 oil-free air and zero harm to the environment. The AQ 15-30 is a small compressor that can have a big impact on the user’s business and the environment. Atlas Copco Compressors Australia www.atlascopco.com.au

CONTROL BOX FOR SENSORS To keep up with changing plant standards, Cerlic has released a 24 VDC version of its centralised BB2 controller. Still capable of managing up to four separate sensors with any combination of the X-Series sensor range of suspended solids (ITX, CTX-LC and ITX-IL), dissolved oxygen (O2X Duo), pH (pHX) and redox (ReX), the low-voltage DC unit is reversecompatible with existing Cerlic equipment and can directly replace a line-voltage unit as part of a upgrade, with no further hardware required. The Swedish-built BB2 provides up to four 4–20 mA analog output channels with the option of Profibus DP for digital control circuits. Like with the line-voltage (240 VAC) model, there are still two independent (dry contact) relays in the BB2 which can be programmed for high/low alarms or to trigger the self-cleaning of sensors (pressured air or water).
