Purpose of the Study
To evaluate the energy, emissions, and performance impacts of using REALice vortex-treated water for ice rink resurfacing, replacing conventional hot water with cold, degassed water in real-world Canadian arena conditions.
Technology Overview – REALice® System
- Uses mechanical vortex treatment to remove microbubbles and entrained gases.
- Eliminates the need to heat water to 140°F (60°C) before resurfacing.
- Produces clearer, harder, more durable ice with less melting and shaving.
- Installed as plug-and-play inline retrofit to arena resurfacing systems.
Study Scope
- 10 indoor rinks across British Columbia participated.
- Ice resurfacing water temperature reduced to ~60°F (15.5°C).
- Monitored over 5–7 months for:
- Natural gas use
- Electricity for refrigeration
- Indoor ice quality
- User and operator feedback
Key Results
| Impact Area | Result |
|---|---|
| Natural Gas Savings | Average: 79% reduction (heating resurfacing water) |
| Refrigeration Energy | Average: 29% reduction |
| Ice Quality | Maintained or improved, less snow, faster freeze |
| Emissions Reduction | Significant GHG reductions across all test sites |
| Ease of Use | Positive staff feedback, minimal disruption |
| Cost Savings | ~$3,000–$9,000 CAD/year per rink (energy alone) |
Feedback & Observations
- Operators reported no negative effects on ice quality.
- Players and coaches observed fewer ruts, less snow, and smoother glide.
- Water heaters remained off for months in some rinks.
Limitations & Considerations
- Refrigeration energy savings vary based on arena efficiency and climate.
- Training staff to adjust resurfacing practices is important.
- Additional ice maintenance practices (like shaving) may need review.
Conclusion
REALice® technology delivers:
- Proven energy savings in real-world arena settings
- Better environmental outcomes (GHG, water heating, refrigerants)
- Operational simplicity for municipal and private rinks
- Faster return on investment (ROI in 1–2 years)
Highly recommended for large-scale adoption across arenas and eligible for FortisBC incentives.
