York Sun Premier RTU range extended

USA: Johnson Controls has expanded its York Sun Premier commercial rooftop range with new 90-150 ton units. 

With a full portfolio ranging from 25-150 tons, the Premier RTUs are said to exceed the US Department of Energy 2023 energy efficiency standards, and most available tonnages meet the Consortium for Energy Efficiency 2024 highest tier ratings. Offered in standard efficiency, high capacity or high efficiency, the York Sun Premier units can provide up to 31% greater efficiency at part-load than is required, depending on the standard.

The RTUs combine variable-speed compressor options, variable-speed drive fan options and lower GWP R454B refrigerant with advanced airflow and heat transfer technologies.

The Premier systems offer the broadest array of airflow features, including various airflow paths and duct configuration capabilities. 

Features including airflow measurement stations, dirty filter gauges, filter pressure transducers and suction, liquid and discharge shutoff valves reduce time on the roof. At the same time, built-in redundancy of refrigeration circuits and variable frequency drives and twinning algorithms enhance reliability and uptime. They are Smart Equipment enabled to seamlessly connect to building automation systems.

The 90-150 ton Premier RTUs are available from York, Johnson Controls and TempMaster in the USA.
