About Liberty




Excellence is the result of caring more than others think is wise, risking more than others think is safe, dreaming more than others think is practical, and expecting more than others think is possible.

The Evolution of Liberty

Liberty Airport Systems can be traced back to 1970 when Westinghouse Canada developed the first modern Constant Current Regulator (CCR). The RSS20 Synchro-Tap CCR soon became the power source for virtually every airfield in Canada.

In 1988, Westinghouse developed a Control and Monitoring System (CMS) based on programmable logic controller (PLC) technology. Continual development based on customer feedback resulted in state-of-the art systems that are known as the most flexible and reliable systems in the industry. In fact, almost every system installed is still in operation today.

In 1995, the Westinghouse Airfield Division was acquired by Hughey and Phillips and later sold to Honeywell International in 1998. In 2004, Liberty Airport Systems Inc. was formed to continue the legacy in power and control solutions.

Since 2004, Liberty has grown exponentially and now has manufacturing facilities in both Canada and the USA. We are ISO 9001:2008 registered and our customer base is now global.
