Airstage, a subset of Fujitsu, specializes in Variable Refrigerant Flow (VRF) systems. A VRF system increases efficiency with the inclusion of a DC inverter to the compressor. This allows for the control of motor speed, and as a result, refrigerant flow, as opposed to a conventional unit, which only supports on/off operation. Airstage also offers heat recovery systems, which save energy by pulling heat from one room and distributing it to others. This allows for the cooling of a room that is too hot and the warming of others that are too cold in an extremely energy efficient manner. VRF systems are perfect for use in both small and large scale commercial operations, and are flexible and easy to install. BTU Reps is considered the strongest HVAC representative in the southeast and proudly enjoys representing Airstage’s line of VRF systems.
