Chiller Facts
  295 Kb

Over 24 percent of the energy in commercial buildings is used or Heating, Ventilation and Cooling (HVAC). Of this energy, more than half goes to building cooling. In larger buildings, chillers are often used for cooling. Chillers are a type of cooling equipment that produces chilled water to cool air. Making your cooling systems as efficient as possible is an important component of reducing building operating costs. This article addresses energy saving opportunities in chillers.

While good lighting is expensive, poor lighting is even more expensive for manufacturing facilities when considering the quality of light issues that impact production. A high-quality industrial lighting system increases productivity and saves money.

Compressed Air

Compressed air is a utility source widely used in industry to power tools and utilized for conveying material, manufacturing and converting processes, and processes such as filtration, refrigeration, and aeration. While other utilities such as electricity, natural gas, and water are often purchased from outside the industrial facility, compressed air, sometimes called the "fourth utility" is almost always manufactured on site.

Variable Speed Drives

In addition to the economic benefits of lower energy costs, variable speed drive can enhance product quality and reduce equipment maintenance. Flow rates and equipment speeds can be automatically and instantaneously adjusted to meet changes in production process requirements. This helps ensure product uniformity and reduce material waste. If equipment often runs at less than its maximum speed, wear can be reduced considerably and maintenance intervals can be extended.
