CALMAC Manufacturing

CALMAC Manufacturing CALMAC manufactures IceBank® Off-Peak Cooling (OPC) tanks. OPC is the process of generating and storing cooling capacity at night-time to reduce peak daytime kW demand and energy usage for hospitals, schools, commercial applications and new or retrofit buildings. Unlike traditional air conditioning systems, Off Peak Cooling reduces daytime (on-peak) electrical loads (kW) by utilizing less expensive nighttime (off-peak) electricity to generate all, or a portion of the building’s next day cooling requirement. During the day, when the electric rates are higher, pumps move glycol through heat exchanger tubes, which are enclosed in ice. The ice, stored in modular IceBank tanks, is produced at night when the demand for electricity is significantly less and is thus produced more efficiently by the utility’s baseload capacity. As power plants produce electricity more efficiently, they emit fewer greenhouse gasses. Furthermore, utilities typically charge less for nighttime produced electricity because electrical demand is reduced and generated more efficiently. OPC conserves resources, reduces cooling costs, and minimizes the need to build power plants by moving the largest portion of the moveable electric load ‘off-peak’. Shifting electric load ‘off-peak’ conserves source energy and reduces emissions because off peak electricity is more efficient to generate and deliver.
