Each circuit with a variable speed compressor must have a variable speed condenser fan to match the capacity and of the compressor. These fans will speed up and slow down to match this capacity and refrigerant pressures to optimize temperature control and efficiency. The vari-speed fans also provide low ambient control at no added charge. The fan blades and shrouds are design for high efficiency and low noise.

1. High Efficiency,
2. Low noise
3. Variable speed condenser fans.
