CALMAC Showcases Thermal Energy Storage System Technology at AHR Expo

Attendees will learn how Kings County Courthouse was transformed into a more sustainable civic landmark with new IceBank® energy storage system

CHICAGO, Ill. – Jan. 22, 2018 – CALMAC ®, a leader in cool energy related technologies and a portfolio of Trane®, a leading global provider of indoor comfort systems and services and a brand of Ingersoll Rand®, will showcase ice-based thermal energy storage technology during the 2018 The International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo®) in Chicago from Jan. 22 – 24.


CALMAC ice storage tanks are integrated with Trane commercial heating, ventilation and air conditioning (HVAC) systems to take pressure off of the energy grid. The ice storage tanks store energy, similar to a battery, and use that energy to cool commercial buildings during times when the cost of energy is high. This reduces the strain on public utilities, reduces operating costs for building owners and allows for better use of renewable forms of energy.

At the expo, attendees will learn about application of the CALMAC system at the new Kings County Courthouse building in Hanford, Calif., which resulted in reducing energy costs by 26 percent, which equates to more than $100,000 in energy savings annually.

“Ice-based thermal energy storage systems are a great solution for customers with energy reduction goals, because they also provide proven reliability and lower operating costs,” said Paul Valenta, vice president of sales and marketingfor CALMAC. “Applying thermal energy storage as part of the design at the Kings County Courthouse was crucial. In California, energy costs vary based on peak and non-peak times of the day. Shifting the load to times when energy is less expensive reduces energy use and saves the county and its taxpayers considerable costs.”
