Best Practices using REALice®

Whiteboard Animation Best Practices using REALice

In short:
  • Avoid trickle-filling ice resurfacer – minimum static pressure 45 psi.
  • Ensure blade is sharp and changed regularly.
  • Shave ice with each flood. Build early-morning dry-shave into routine.
  • Drive slowly to clean ice: NHL: 8-10 minutes, Olympic: 10-12 minutes.
  • Reset brine temperature from 2-5°F higher with gradual 1°F increments.
  • If indoor temperature in arena falls below freeezing, use REALice-treated tempered water.
  • Use REALice hand-held for building ice, spot-maintenance and repairs.
  • REALice-treated water never needs to be dumped: it will last for the next flood – even overnight.
  • REALice water and normal water cannot be mixed: Don’t bypass the system.

All water used for your rink needs to be treated –

Do not Bypass the System!


After install of REALice®

First, increase the ice temperature to make it easier to shave the ice. Shave the ice to just above lines and/or advertising. After you are finished shaving, return to the normal ice temperature.


Building New Ice

Use REALice® Treated cold/ambient water. Normally, REALice® is used with only cold water. In some circumstances, it may be necessary to add some warm water. This is seen more when there is very cold water near 40 degrees F and/or if the brine temp either has not been reset upwards or if there are inconsistencies in resetting the brine temperature. Try adding a little warm water (REALice® treated) at a time, if you do not get good results with only cold water.

Use the REALice® handheld nozzle to build very think layers for both new ice after taking down the rink and also for building ice over existing ice.

Adjust temp. as needed typical cold water Note: The recommended unit installation is to allow hot/cold mixing. This can help with rate of freezing, as does confirming accurate control of brine temperature.


Water Pressure

Needs to be at least 45 psi
City water usually 45 – 60 psi
Avoid trickle filling the ice resurfacer – pressure is needed to guarantee the REALice treatment of the water


Resurfacing Tank

Fill with only REALice® treated water


All cold or mixed

Do not mix REALice® treated water with untreated water!

Normal water and REALice® treated water have different properties and should not be mixed. The different waters have different freezing characteristics and various ice crystals. Mixing water will give you a poor ice quality and higher energy consumption. The effect of REALice® treatment lasts at least 24 hours. This means that you can fill up the ice resurfacer in the evening before next day’s work.


Wash water

The wash water in the ice resurfacer may need to be slightly warmer (20C/68F), and not cooled by the re-circulating water, to prevent it from clogging.

Does not need to be REALice® treated water – or can use REALice® but need to use mixing to make warm.


Typical ice thickness is about 30mm, or 1.25”.

Will vary based on your conditions or if rink is covered for other events


Adjusting Ice Temperature (Brine Temp) and the Snowball Test

If the ice is too warm, it becomes soft and tough. If too cold, the ice becomes dry and brittle, and snow will build up on the ice.
The temperature of the ice’s optimal range is different from ice rink to ice rink, based on climate zone, spectators, age and use of refrigeration equipment, etc.

The best way to find the optimal range is to raise ice temperature in small increments, about 1-1.5°F (0.25 to 0.50°C) at a time and then wait a couple of days.

During this time, study the ice quality. This is repeated until you feel that the ice quality is too bad.

Then you lower the ice temperature one step.

Is there accurate automatic control of the brine temp? How is brine temp for the specific rink measured/controlled?





Ice made of REALice® treated water is more durable than ordinary ice. This means that it does not get as many or as deep of scars and injuries in a REALice® compared to regular ice. This also means that the water that is added at each resurfacing usually can be reduced or use fewer resurfacing rounds. It is important that you shave the ice not only “collect” the snow.



High humidity creates rime on the ice and therefore produces more snow. To obtain optimal ice, the humidity in the ice arena should not exceed 50-55%. Also very low ambient temp, (less than 50F) especially if the temp approaches the dew point can cause fogging and frost/rime on the ice.

What is the humidity and dew point?
