Retrofitting an existing chiller involves upgrading it to operate on an environmentally friendly refrigerant. This procedure is most desirable when a building owner faces budget constraints and space or accessibility problems.
Retrofitting is also ideal for chillers that are less than ten years old. Because these machines are newer, they reflect the improved efficiencies of today's designs and have much of their useful life remaining.
The benefits of retrofitting an existing chiller typically include cost savings, extending the life of the chiller, and no additional expense associated with piping modifications. These retrofits often result in efficiency improvements that can actually reduce operating costs.
