McDonnell & Miller: BOILER CONTROLS

The M&M Series 750B is a new line of conductance-activated level controls for commercial/industrial steam and hot water boilers. The main function of the controllers is to provide low-water cutoff protection and level control. The controllers provide point-actuated level control, pump on, pump off, or high-level alarm. Two models are available: 24 vac and 120 vac, with manual or automatic reset capabilities. The remote chamber is designed for steam pressure to 250 psig. The probes mount on the remote chamber or directly in the boiler shell.

McDonnell & Miller, 8200 N. Austin Ave., Morton Grove, IL 60053; 773-267-1600; 773-267-0991 (fax); www.mcdonnellmiller.com (website).
