In 2015 the Mobile, AL Children’s and Women’s hospital integrated a ChillMaster modular heat recovery system into their existing hot and cold water system to improve efficiency and reduce energy cost. Once installed, the modular heat recovery system was estimated to save the hospital $400,000 a year.

The University of South Alabama Medical Center in Mobile was provided with a ChillMaster 30 ton domestic hot water system in 2007. The system exceeded expectations and was able to completely replace the hospital’s gas powered boilers with clean electric energy. After nine years of satisfaction with their 30 ton domestic hot water system, the University of South Alabama decided to use ChillMaster again in November of 2015 for a heat recovery project at the Children's and Women’s Hospital also in Mobile.
This project required a 490 ton modular heat recovery system to tie into the existing hospital’s hot and cold water systems. The idea was to take heat out of the return chill water loop and transfer the heat to the hot water loop. This would pre-heat the water entering the boiler and pre-cool the water entering the chiller simultaneously. This would allow for massive energy savings due to reducing the load on the chiller and the amount of gas used by the boiler. The project was estimated to save the hospital nearly $400,000.00 a year in energy savings with a payback of less than three years.
The system was designed with several unique features including a single point connected electrical bus bar, power and flow meters, wireless remote monitoring via internet connection, automated system email notifications, constant data trending, and extended all-inclusive 24 hour maintenance coverage. These features along with 14 independent stage operation, automatic lead lag, ambient air reset, and external boiler control, have allowed the system to once again exceed expectations. The system is currently saving an average of $40,000.00 per month for the Mobile, AL Children’s and Women’s Hospital.
