Chiller Optimization,
Revitalization & Service
Get modern performance at a fraction of the cost and lead time of replacement.
Why Replace What You Can Revitalize?
Chiller performance declines over time—but declining performance doesn’t necessarily mean the equipment has reached the end of its useful life.
Dalkia benchmarks your existing system against its original design performance, identifies where efficiency and capacity have been lost, and develops a targeted combination of retro-commissioning, repairs and energy upgrades to recover that performance.
The result is a more efficient, reliable chiller plant without the cost, disruption and lead time of unnecessary replacement.
Replacement is the last resort.
