Ice Quality

Of course ice quality is something that is after all largely subjective.

What could be noticed though is that better ice:

 

  1. produces less snow
  2. creates fine powdered snow
  3. the lines are showing better / more transparent

From REALice® user Feedback:

 

How would you rate your ice quality:

Excellent0%
Good0%
Satisfactory0%

What is important to mentioned that in the ice maintenance process not only the snow is removed with the ice machine but also the ice also shaved 1mm per round to eliminate the scars and make it nice and transparent again.

REALice® is used by the NHL for all their outdoor games, Winter Classic, Heritage Classic and Stadium Series, since 2010.

Through ice crystal comparison it was shown that the ice made with REALice® treated water is

 

  • stronger,
  • more homogenous
  • and has a higher heat capacity

 

leading to reduced energy usage in ice rinks. With the ice crystal being bigger, the density of the ice increases.

  • The conclusion is that the rebound or hardness numbers are as good or better after the installation of the REALICE system, which meets the intent of the measurement and verification process.
  • For Rink A the ice was on average 39% harder post installation of REALICE with a high of 80% and low of 11%.
  • For Rink B the ice was on average 46% harder post installation of REALICE with a high of 80% and a low of 14%.
  • The overall uniformity of ice strength is much better after the installation of the REALICE system. This means that the ice was more consistent in hardness across the entire rink after installation.
