QUICK ANSWER
McKenna Boiler Works, Inc. supplies, installs, and supports remote boiler monitoring for industrial plants across California. The McKenna MBM2 and MBM3 units connect to the combustion controller over Modbus and to analog and digital sensors, then send live data, alarms, and history to a secure dashboard over a cellular or network connection. Alerts go out by text and email, and first-out annunciation records which safety limit opened first. Both units are monitoring only, and the boiler’s hardwired safety limits stay local. Family-owned since 1921. Call (323) 987-1816 or email info@mckennaboiler.com.
