Boiler Level Controls

Level controls are critical in all boiler and boiler room applications. The D. B. Johnsen Company recommends level controls manufactured by Mercoid, Magnetrol, and McDonnell & Miller depending on the boiler room application. They are used for low water cutouts (LWCO), level control, pump control, and alarm warnings on boiler room equipment such as boilers, deaerators, condensate tanks, and surge tanks, just to name a few. Although there are many other level controls available in the marketplace, these three have proved to be the most reliable, affordable, and accessible for maintaining boiler room equipment.


To request pricing or order level controls, please call the D.B. Johnsen Company Parts Department between 8:00 AM - 4:30 PM EST at 1-800-442-1242 or click here to email us.
