INSTALLATION, CALIBRATION, and REPAIR

In 1933, more than ninety years ago, Mr. C.R. Davis founded a self-employed service company performing boiler service and repair in downtown Toronto, moving from one call to the next on his bicycle.

Over time, the service arm of Davis Automatic Controls was renamed Automatic Watchdog Controls, with both the sales and the service companies sharing the distinctive Great Dane logo, which by itself reflects the attributes of Davis Controls; friendly, strong and dependable.

From our roots in boiler service and repair, our expanded capabilities now include in-house instrumentation and control repair and calibration, onsite maintenance, service and calibration, BTU system installation, commissioning and annual calibration, instrument audits, Nitrogen Generator maintenance, equipment lubrication audits, flow system verification and VFD commissioning and repair.
