TACAS Technology

The CoolAir DC stores energy in the form of compressed air and heat. During a utility outage, the compressed air is routed through a Thermal Storage Unit (TSU) to acquire heat energy. The heated air spins a simple turbine/alternator to produce electric power. The CoolAir DC also contains a small, continuous-duty flywheel to support the critical load during the brief period required for the turbine to spin up to speed.
