This design wb temperature may occur less than 1% of the year. At all other times, the wb and condenser water temperature will be less and the chiller capacity will be greater than the rated capacity.
Chiller operation in this "greater than normal" range is often referred to as the "max-cap" range and varies greatly with manufacturers and models. The max-cap range may be as little as 100% to 105% of the nominal rating, or as great as 100% to 140% of the nominal rating.
