IceBank® Energy Storage Systems: A Better Way to Air-Condition™
CALMAC - The World Leader in Off-Peak Cooling

CALMAC Manufactures Ice Storage and Ice Rink equipment.

CALMAC is the world leader in the product design and manufacture of energy storage for commercial air-conditioning systems. Ice is made at night and used the following day to cool the building.

A Greener way to Air-Condition

IceBank energy storage tanks store renewable energy, like wind and or inexpensive clean efficient night-time electricity, in the form of ice for comfort cooling use during peak demand periods the next day. Reducing the peak daytime demand for electricity can cut cooling costs 20-40%, source energy and emissions are reduced and construction of new power plants and transmission lines can be delayed or eliminated.

Top Companies around the World Trust CALMAC's cool energy products.

CALMAC partners with banks, schools, hospitals, offices and retail stores to reduce peak energy demands and cooling costs.  This helps buildings earn LEED Certification and helps meet or exceed energy code requirements.

The IceMat ice rink is well suited for World Championship figure skating rinks, hockey rinks, permanent and portable rinks, backyard rinks and bobsled runs.
