RealTime O2 Feedback™ technology is now available to the public as an easy retrofit solution for new CREST® Commercial Condensing Boilers and can also be added as a factory-installed option to CREST boilers in production. Compared to some O2 systems offered by competitors, Lochinvar’s version constantly monitors the fuel/air ratio when the boiler is running and provides a real-time report to allow for instant adjustments. Gives facility managers access to immediate combustion and carbon emissions data. Users can check O2 and CO2 levels in real time via the control panel or by using the CON·X·US® Remote Connect platform.
