Johnson Controls International : Quantech™ QWC4 Air-Cooled Screw Chiller Delivers High Energy Performance and Efficiency with Cutting-edge Design

• Johnson Controls adds Quantech™ QWC4 Air-Cooled Screw Chiller to brand's expanded chiller portfolio
• New chiller using variable speed drive technology to reduce energy costs and carbon emissions by as much as 30 percent, showcasing Johnson Controls dedication to sustainability and innovation
• Supports Johnson Controls commitment to OpenBlue suite of connected solutions focused on delivering building solutions that help enhance occupant safety while increase facility efficiency

MILWAUKEE - (June 7, 2021) - Johnson Controls, the global leader for smart, healthy and sustainable buildings, today announced the Quantech™ QWC4 Air-Cooled Screw Chiller has been added to the brand's expanded chiller portfolio.

The Quantech™ QWC4 chiller uses variable speed drive technology to reduce energy costs and carbon emissions by as much as 30 percent when compared to traditional chillers. Throughout most locations, the variable speed drive saves energy during 99 percent of operating hours spent at off-design conditions, which include reduced load and/or reduced entering condenser water temperature.

New chiller using variable speed drive technology to reduce energy costs and carbon emissions by as much as 30 percent, showcasing Johnson Controls dedication to sustainability and innovation.

Since the Quantech™ QWC4 screw chiller is capable of handling a higher-pressure lift than a centrifugal chiller, it can be used in both thermal-storage and heat-pump applications. The variable speed drive technology provides the chiller flexibility in handling high-lift applications with the highest efficiencies available. This allows the chiller to use a wide range of heat-rejection methods, including an open cooling tower, dry cooler, adiabatic cooler, heat recovery or heat pump.

The Quantech™ QWC4 chiller also reduces environmental impacts by directly managing refrigerant charges and potential leak points. The chiller utilizes the R-134a refrigerant, which has zero ozone-depletion potential, and features an innovative design that reduces the number of potential leak points by 35 percent when compared to conventional compressor designs. It also incorporates a falling-film evaporator that allows for refrigerant charge to be lowered by as much as 30 percent compared to standard chillers.

The Quantech™ QWC4 chiller supports OpenBlue Healthy Buildings by Johnson Controls - a complete suite of connected solutions that delivers impactful sustainability, new healthy occupant experiences and respectful safety and security to many industries including workplaces, hospitals, schools, enterprises and more.

Quantech™ will be hosting a webinar covering water-cooled chillers on Thursday, June 24th at 2:00 p.m. (EST) The 'Water-Cooled Chillers 101' webinar will take a deep dive into the features and benefits of water-cooled screw and scroll chillers, including the Quantech™ water-cooled chiller portfolio.
