The TSU-M ICE CHILLER® Thermal Storage

The TSU-M ICE CHILLER® Thermal Storage Unit reduces energy costs by storing cooling while shifting energy usage to off-peak hours. The internal melt process has an easy-to-design closed loop making it ideal for a variety of HVAC applications. Some examples include office buildings, district cooling for urban settings, schools, hospitals, sports arenas, convention centres, and more.

Thermal Capacity: 396 - 550,660 ton hours

HVAC Applications


Reduced Energy Usage

Reduce electrical cost for the system by 50% or more by shifting usage to off-peak hours since most electrical rates include demand charges during peak demand times

Save on peak energy and reduce the total system cost with colder melt-out temperatures compared to competitors that use plastic vs. the TSU’s galvanized steel coils


Low System Installation Cost

Systems with ice thermal storage can be installed at a lower first cost than traditional systems since the colder supply water minimizes the sizes of piping, pumping, air handling, and ductwork

Many utility companies offer time of day rates to help reduce operating costs. Several utilities offer attractive load shift incentives and rebates to reduce capital costs

Maximize footprint savings with BAC’s optional custom coils that can be stacked to fit in a field erected tank


Low Environmental Impact

Enables the storage of clean renewable energy while reducing stress on the electrical grid

Ice thermal storage is a green technology according to the USGBC allowing for an opportunity to earn LEED® points in several categories, including Optimized Energy Performance and Demand Response

Reduce electric peak demand by at least 10% in an automatic system complying with ASHRAE Standard 189.1, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings
