Digital control panels from Wattco, Lachine, Quebec, received UL certification.

When a control panel is to be installed in areas where dangerous concentrations and quantities of combustible gases or vapors are present in the environment, enough protective measures must be taken to reduce the probability of explosions due to ignition by hot surfaces either during fault or even during normal conditions.

Controls panels that are responsible for managing, or come into close contact with, explosive elements are enclosed in a specialized container made to withstand high pressure or explosions. The specialized enclosures are built to contain the explosion so that it does not spread to the surrounding area.
