Reduce, reuse, recycle.
In an age where greener is better, the KN Series cast iron boilers are an environmentally friendly, condensing cast iron boiler option for a wide range of commercial boiler installations. As condensing boilers, the KN Series units are constructed with a durable cast iron heat exchanger, enabling each unit to cycle longer and less frequently, as it retains latent heat longer and requires less energy to bring back to operating temperature. When coupled with the precise digital controls of HeatNet 3.0 boiler control software, KN Series offer optimum efficiencies through full modulation.
The specially designed cast iron heat exchangers at the core of all KN Series boilers are manufactured utilizing over 90% post-consumer recycled materials, which makes them completely recyclable.
Upon installation, KN Series condensing boilers are quiet and operate up to 99% energy efficiency level while maintaining low NOx and CO2 levels, qualifying for the South Coast Air Quality Management Divisions (SCAQMD) Rule 1146.2 standards.
