The desire for a future-proof system led Nationwide Arena to select an indirect CO2 system from CIMCO.
The new energy-efficient CO2 system, an Eco Chill solution from Canadian contractor Cimco, replaces a R22 system from 1994.
The company’s requirements included a natural refrigerant, quick installation and energy efficiency.
As a direct system, the transcritical equipment cuts operating costs, says Cimco.
Following settlement, the two Quebec companies will will be able to supply CO2 refrigeration systems for ice rinks.
The ATMOsphere Review Panel has selected the second round of CO2 case studies – from Danfoss, CAREL and CIMCO – to be presented at ATMOsphere America 2017.
