There have been a number of complaints about the ice conditions throughout the National Hockey League recently. From Gila River Arena in Arizona, to Rogers Place in Edmonton, and east to the Barclays Center in Brooklyn; the quality of the ice has been discussed.
Underneath the concrete floors in all NHL arenas is a refrigeration system. The ice surface is made on top of those concrete floors prior to the start of the preseason. Eighteen arenas feature CIMCO cooling systems for ice refrigeration, including T-Mobile Arena which will soon become the thirty-first arena in the NHL.
