With years of proven experience , the Knight XL expands on its already tried and true feature set. Making hard work look easy, this commercial boiler steps out front. Available in five models ranging from 399,000 to 999,000Btu/hr, the advanced units feature 97% thermal efficiency and 10:1 turndown. The 7" touch screen with built-on CON-X-US provides a better end user experience allowing parameters to be adjusted with minimal effort and provide access to the remote connectivity when required for the installation. The stainless steel water tube heat exchanger is an enhanced design that provides a 3% increase in thermal efficiency over previous KNIGHT XL design, lowering operating cost and boiler emissions. The KBX0500 has an operating range from 500,000 BTU/HR input all the way down to 50,000 BTU/HR input matching the majority of commercial heating load requirements, eliminating short cycling of the heating system. The combustion air filter collects debris from combustion make up air, potentially extending time between burner and heat exchanger cleanings.
