Watlow Large and Extra-Large WATCONNECT® Panels

Watlow’s New WATCONNECT® Large and Extra-Large Panels Maximize

Process Uptime with Small Footprint

Watlow’s new WATCONNECT® large and extra-large control panels

are designed to maximize process uptime with a small footprint.

Unlike most control panels installed in the field, WATCONNECT large

and extra-large control panels permit safe access to control compartments

allowing users to troubleshoot without shutting down the process.

In addition, the large and extra-large panels only require 50% of the

space of competitive panels, which frees up areas for other critical

equipment needed in the process.

As an additional option, the Data Insights Package offers remote monitoring

to the cloud of thermal system analytics such as power and control health,

failed element detection, process continuity and more.

All WATCONNECT control panels are pre-designed for a proven, high-quality

solution.
