BLAC INC. provides multiple control systems for all industries to operate on off or modulating valves and dampers.  These control systems range from analog type to PLC based units.  The PLC based units are primarily what is supplied on modern control systems, but BLAC INC. still supports all legacy products of analog design with original equipment components and PC boards.

Upgraded control systems can be provided for any application, either supplied originally by BLAC INC. or by a competitor.  Consulting services are provided to determine the existing control system that may be in place at any plant, and to provide the various solutions that are available for consideration in the plant upgrade.
