P-K STORM® Condensing Boilers

Standard 10:1 Mechanical Turndown 
10:1 Turndown Technology Increases Efficiency and Reduces Operating Cost

Patterson-Kelley has achieved higher turndown with a unique mechanical process that allows the gas valves to control boiler performance without increasing excess air. This results in building flexibility and efficiency.

This method delivers a 10:1 turndown rate while preserving a high dewpoint, which helps maintain high condensation levels. This higher turndown capability will provide designers the ability to match input to building loads without sacrificing efficiency and reliability. No more nuisance flame failures that have traditionally plagued high turndown boilers.

Outdoor Technology Options Available On Models ST1250-ST2000

Factory assembled and tested for outdoor installations with efficiencies up to 97% and a 10:1 mechanical turndown rate, outdoor models come assembled from the factory without requiring time in the field to make conversions. For buildings with limited indoor space, this option on the P-K STORM® is ready for any predicted forecast.

NURO^® Touch-Screen Control SystemTurndown energy usage

All of our boilers are equipped with the most intuitive interface in the industry, the NURO® Touch-Screen Control. Designed to maximize efficiency, the NURO® Control System monitors and modulates the combustion and ignition of the boiler to maintain the desired outlet temperature.
