CALMAC has not always been known by this name.  Originally named Jet Heet Inc., engineer Calvin “Cal” MacCracken opened his engineering firm in 1947 after graduating from Princeton and MIT.  He had already developed the combustion chamber for the world’s first jet engine for General Electric. 

Cal moved to New Jersey and in 1964, he renamed his company CALMAC.  His son Mark joined the company in the mid-70s and because of his interest in environmental protection, CALMAC began doing research and development on solar energy and thermal energy storage.  

The CALMAC facility was completely destroyed in a fire in December 1980.  Rebuilding from the ground up allowed the opportunity for them to turn their attention to one singular focus:  thermal energy storage. 

How does this system work?  The system makes ice at night while the electricity demand is lower.  The ice is stored in the CALMAC IceBank® storage tanks and then melted to cool the building when air conditioning is required and electricity demands are higher.  This technology led to the explosion of the green building industry. CALMAC helps their clients reduce their carbon footprints, and in some cases, achieve LEED certification. 

IceBank® energy storage tanks are used in medical centers, hotels, universities and other commercial buildings in 60 countries. CALMAC is the only manufacturer in the world whose main production is ice-based energy storage.  

Additionally, CALMAC produces plate heat exchangers that offer easy maintenance and greater efficiency. 

CALMAC also offers two different IceMat® ice rinks that provide a greater heat exchange and allow for the production of quality ice even when the temperature exceeds 90°F. The main header is factory-installed and is more efficient than conventional refrigeration piping systems. 

IceBank energy storage is the cooler, greener and smarter option for air conditioning around the world.
