Loren Cook 778542 Rotary Belt Tensioner is an essential component of HVAC systems and is responsible for regulating the working of these systems. It is used to maintain belt tension and hence avoid belt slippage and belt damage. This is made possible through the fact that it only applies pressure on the belt’s surface to correct for variations in load as well as temperature. Some of the benefits of this design include; low noise levels, better air flow and low energy consumption. It helps balance the tension right and allows HVAC equipment to function effectively.
