This company has added four additional sizes to the Arctic Series of condensing boilers (photo). The new models range from 1.5 to 3 million Btu with certified efficiencies of 95%. The stainless-steel boilers feature a non-welded heat exchanger. Arctic boilers are available in fully packed or knock-down configurations, allowing them to fit into spaces where other condensers are not easily installed. An Arctic boiler accommodates variable primary and secondary piping designs due to minimal waterside pressure drops and low minimum flows. A 5:1 burner turndown is standard, with a 20:1 option to be available later this year. — Thermal Solutions LLC, Lancaster, Pa.
