Dunham-Bush ACDS180: A Future-Focused Chiller for Cedar Rapids Airport

Dunham-Bush has been delivering reliable, high-efficiency cooling solutions for well over a century. Their diverse chiller portfolio includes water-cooled centrifugal chillers, screw chillers, modular scroll chillers, and air-cooled scroll chillers—each engineered to balance performance, sustainability, and long-term dependability. Among this lineup, the ACDS Series air-cooled scroll water chillers stand out for their versatility and environmentally conscious design, with capacities ranging from 10 to 180 tons.

Spotlight on the ACDS180

At the top of this series is the ACDS180, a 180-ton air-cooled scroll water chiller charged with R-454b, a next-generation low-GWP refrigerant. This unit is designed not only for efficiency but also for longevity—and it will be doing just that for decades to come at the Cedar Rapids Eastern Iowa Airport, where it is tasked with providing dependable comfort cooling for travelers, staff, and facilities year-round.

Why It’s Built to Last

• Sustainable Refrigerant: R-454b delivers the cooling capacity of traditional refrigerants while dramatically reducing environmental impact.

• Robust Engineering: Brazed-plate heat exchangers, corrosion-resistant construction, and dual/multiple scroll compressors ensure reliability and simplified maintenance.

• Certified Performance: Backed by AHRI and ETL certifications, guaranteeing energy efficiency and safety standards.

• Smart Controls: Equipped with advanced microprocessor controls for seamless integration with modern building management systems.

Options That Add Flexibility

The ACDS series, including the 180-ton model, supports a range of upgrades to tailor the system to specific project needs:

• Extended low-ambient operation for harsh climates.

• Noise-reduction options for sensitive environments.

• Heat recovery capability, capturing waste heat for hot water applications.

• Protective coatings and monitoring tools for challenging conditions.

A Smart Choice for Airports & Beyond

Large-scale facilities like airports demand equipment that is efficient, rugged, and adaptable. The ACDS180 checks all those boxes, making it a strong fit not only for Cedar Rapids but also for commercial, industrial, and institutional projects across the Midwest. With its proven durability, intelligent controls, and eco-friendly refrigerant, the ACDS180 is set to deliver reliable cooling for decades to come.
