Patterson-Kelley is excited to introduce their very first firetube boiler, the P-K SOLIS®! This top-of-the-line, highly efficient condensing boiler is designed to maximize comfort without sacrificing savings or floor space. Each P-K SOLIS® model features a unique geometric design that optimizes heat transfer, resulting in efficiencies of 97%, 10:1 mechanical turndown, and ultra-low NOx emissions.
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.
The heat exchanger is designed to provide simplified and quick annual maintenance. The top of the heat exchanger opens, providing full access to the tubes and burner inside the unit. This makes any maintenance, including cleaning, a quick and cost-effective process.
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.
