Hydrotherm’s KN-30 high-efficiency boiler is the largest in the KN series of boilers, producing 3 million Btu while maintaining the long-lasting durability of cast iron and the high efficiency of condensing boilers in a compact footprint. The KN-30 comes equipped with HeatNet, Hydrotherm’s proprietary, integrated boiler man-agement system. Through continuous monitoring of several system parameters, including boiler temperatures, limit circuit inputs and overall system demands, HeatNet modulates boiler-firing rates to maximize turndown ratios, maintaining peak efficiency regardless of the load. HeatNet maximizes system performance in both standalone boiler applications as well as cascading multi-boiler Master/Member networks.Hydrotherm. www.hydrotherm.com. Circle 4
