Chiller Economizer Case Studies - Global Summary

In 2009. Legacy Chiller Systems launched a first of a kind system the offers real-time chiller economizer savings data to the general public.  This system offers summary data (table below) as well as detailed site telemetry that can be accessed by clicking a site link or your choice.

Legacy Chiller Systems offers design, setup and implementation live and virtual case studies for any brand or size chiller application. Case studies can be a very useful to verify savings concepts prior to full program rollout. For more information call 877-988-5464 x 101 or click Live Chat to the left.

Important Site Information

Savings data is depended on your chillers operating environment. This is a Virtual Case Study Site.  This virtual site is using real-time weather data being collected approximately every sixty seconds from the National Weather Service.  Process loads on this chiller application are simulated using Legacy advanced chiller simulator technology. Photos on this page are stock photos from Legacy installed sites.
