- It is possible to use cold/ambient temperature water to resurface ice instead of hot water
- Save thousands of dollars per year from electricity, gas and maintenance costs - Simple retro-fit (1 to 2 hours of a certified plumber’s time)
Help your members to: • Save on operating cost & emissions • Make great ice, even at the start of the season with increased outdoor
temperatures • Be at the forefront of innovation
Introducing a high precision de-aeration device that lowers the utility costs of ice making!

Arena Energy Use 2008-2014 (kWh / GJ)
Electricity saved: 152,908 kWh Natural Gas saved 333.4 GJ

Large Scale FortisBC Pilot Study 2014
90% of the pilot participants successfully adapted their operations to the REALice® technology.
The achieved ice quality was evaluated from acceptable to excellent.
FortisBC quantified the average savings across the participating pilot arenas at 330 GJ in Natural Gas per year,
- A reduction of 79%!
Across the pilot arenas, an average increase of 3°F in slab temperature was observed.
Ice slab thickness was reduced on average by 0.25 – 0.5 inch.

Cold water has approx. 3 times more micro air bubbles than hot water! Solid ice can’t hold air - if not removed, it forms bubbles
Viscosity is lowered - water flows out faster
How does it work - Why degassing / de-aerating?Removing of micro air bubbles
Degassing Demonstration

REAL ice is simulating “hot water”
Viscosity decreased: water flows out faster (3% - 17%)
Heat capacity increased: ice lasts longer, melts slower
Electrical conductivity increased: brine works more effective / less insulation
Reduces lime scale - calcium bicarbonate (CaHCO3) is transformed into calcite & preferentially aragonite, which does not attach to pipes, nozzles or other surfaces = softens the water
No change in surface tension
Effects on the Water
Investigations of ice crystal structure were made at Luleå Technical University, Sweden, 2011
Degassed / De-aerated Water forms Larger Ice Crystals = denser sheet of ice
less draw on compressors & boilers (approx. 25% down) less dehumidifier run timeless rust on structural beams
less ice cleans needed less condensation in the arena less water used, and wasted
less energy used less money spent on electricity & natural gas less CO2 emitted
longer amortisation on equipment
Domino - Effect using Cold/ambient Temperature
More ice-time!
Savings Potential: Natural Gas 79%
Electricity 10% - 12%
