LACAZE ENERGIES’ electrical power, protection and regulation boxes are designed to be combined with one or several cylinders with or without an electric backup.

Because every installation is different, they can also be tailored to meet specific needs requiring a particular operating mode or equipment (water level regulation system, hydraulic accessory or burner controls, information logging, etc.). Each component is chosen with meticulous care to offer you boxes that combine quality and reliability.
