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 Canadian contractor will no longer make systems that use HFCs or HFO blends like R513A.
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.
The majority of the rinks were retrofits that replaced synthetic refrigerants – and save up to 50% in energy, the company says.
The National Hockey League and Chemours are promoting HFO blends R449A and R513A as green refrigerants, though CO2 and/or ammonia would be greener, say industry stakeholders.
Canadian contractor is installing rooftop transcritical systems for industrial operators.
Following settlement, the two Quebec companies will will be able to supply CO2 refrigeration systems for ice rinks.
