Chillers

Optimize your buildings’ energy efficiency with today’s advanced chiller technology.

Chillers cool buildings and industrial processes. Recent advances in chiller technology and design practices have greatly improved energy efficiency. The Sponsors of Mass Save® help commercial, industrial, and public-sector customers evaluate their options for chiller design and implementation. Engineering services are available to establish budgets, estimate savings projections, and develop plans. In addition to engineering guidance, the Sponsors offer financial incentives that help to defray the cost of eligible energy efficient chiller technologies.
