Trane has acquired CALMAC Corporation, a privately held company specializing in cool energy technologies including IceBank® storage tanks. The value of the acquisition was not disclosed.
CALMAC ice storage tanks are integrated with Trane commercial HVAC systems in an effort 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. According to officials, this reduces the strain on public utilities, reduces operating costs for building owners, and allows for better use of renewable forms of energy.
