Consider a New Cooling Tower

Cooling towers are one of the most overlooked opportunities for saving energy in cooling plants. Cooling tower technology has improved over the last 10 years. The average tower today operates at about .12 kw/ton, while new, efficient, plastic-filled, counterflow towers can perform at .011 kw/ton (10 times better). These efficient towers use less fan horsepower per unit of cooling but, more importantly, they deliver cooler water to the chiller(s). For centrifugal chillers, each degree F the condenser water temperature is depressed, the chiller efficiency will increase about 1 percent.
