COMMERCIAL CHILLERS
The Trailblazer is Daikin Applied’s first available unit designed with R-32 refrigerant, boasting a 33% reduced footprint and 10% reduced weight. Trailblazer chillers
operate in off-design conditions 95% of the time, providing 10% greater capacity and efficiency compared to competing units at both design and off-design conditions. With a 10 to 240 ton range, the Trailblazer gives you the scale to fit your cooling needs, and offers the best overall value in air-cooled packaged chillers available today. Its quiet operation, high efficiency, RapidRestore® and new heat pump technology (model EWYQ) make these chillers ideal for mission-critical buildings, data centers, healthcare, and manufacturing facilities. Furthermore, the utilization of the low-GWP R-32 refrigerant, combined with its high efficiency, presents the best solution for decarbonization while proactively addressing upcoming federal legislation aimed at phasing out higher-GWP refrigerants like R-410A.
JUST ANNOUNCED AFTER PRINT PRESSTIME: Daikin's new Trailblazer (model AGZ-F) is one of the first chillers available in North America with low-global warming potential (GWP) and highly efficient R-32 refrigerant. The company has also added a closed-loop version of the Pathfinder with Free Cooling (model AWV) to its portfolio. Ideal for data centers and other energy-intense applications, this chiller delivers the efficiency benefits of an integrated water-side economizer, commonly known as "free cooling," while eliminating the need to use glycol in the building water loop as an antifreeze.
The low-GWP plus high capacity and efficiency of R-32 is a leading combination for decarbonization. With R-32, Trailblazer AGZ-F delivers 10% greater capacity and efficiency versus previous models, with the potential to provide cost savings and reduce carbon emissions. Also, with a 33% reduced footprint and 10% reduced weight, AGZ-F presents a more compact solution for engineers, contractors, and building owners and operators cognizant of limited space.
With a 30- to 240-ton range, AGZ-F features composite condenser fan blades as well for a simpler mechanical design with less potential for parts failures and related maintenance spend.
The use of R-32 proactively addresses federal legislation to phase out higher-GWP refrigerants such as R-410A. Along with the new Trailblazer chiller, Daikin is working to integrate R-32 into more of its applied offerings. That's because the refrigerant has a reduced GWP compared to R-410A, which lessens the warming impact per pound of refrigerant. R-32 also requires a lower refrigerant charge per ton of cooling compared to popular alternatives, reducing the amount of refrigerant needed. And R-32 has a positive impact on unit efficiency, which trims the kilowatt-hour consumption and grid-level emissions associated with electricity grids that rely heavily on fossil fuels to generate electricity.

YORK
The YORK® YVAA Style B air-cooled screw chiller is an evolution of the first-generation YVAA, is engineered to drive efficiency now and meet or exceed future regulatory requirements. The R-1234ze refrigerant has a zero ozone depletion potential (ODP) and a GWP of 7, which is well below the Environmental Protection Agency’s (EPA) SNAP requirement, making the YVAA Style B a future-forward solution for hydrofluorocarbon (HFC) phase-down requirements.
YVAA Style B chillers are equipped with state-of-the-art technologies, allowing reliable operation for a wide range of -10 F to 130 F ambient temperatures. YVAA Style B can reach capacity ranges spanning from 100 TR to 400 TR for comfort cooling applications, and 200 TR to 500 TR compatible with data center mission critical requirements. A configurable design meets stringent data center requirements of higher leaving water temperatures up to 75 F.
YVAA Style B chillers have been tested in applications across the globe for more than a decade and offer greater flexibility and configuration options for maximum performance with a smaller footprint.
