Gas-powered ice resurfacers, using natural gas or propane, release carbon monoxide and nitrogen oxides, which can cause acute poisoning, respiratory irritation, and exacerbate asthma. In arenas, polluted air tends to settle near the ice surface, making exposure higher for players during training or games. Numerous cases in Canada highlight hospitalizations and health incidents linked to inadequate ventilation and malfunctioning machines.
How Do Electric Ice Resurfacers Improve Air Quality?
Switching to electric ice resurfacers nearly eliminates indoor emissions, keeping carbon monoxide and nitrogen oxide levels at or below outdoor standards. Studies in Ottawa and Saskatchewan demonstrate that repeated use of gas-powered resurfacers caused pollutants to accumulate throughout the day, while electric machines maintain a clean and safe environment. Beyond reducing pollutants, electric resurfacing lowers strain on ventilation systems and enhances comfort for athletes and spectators.
Why Are Arenas Transitioning to Electric Machines?
Climate change mitigation and health considerations are driving the shift. Electric machines, although more expensive upfront, reduce operational costs through lower fuel consumption and maintenance. Municipalities like Mississauga and Montreal are actively replacing gas fleets with electric resurfacers to meet sustainability goals, improve indoor air quality, and ensure long-term cost efficiency. Financial incentives in certain provinces also support this transition.
Which Models and Technologies Are Leading the Transition?
Brands like Zamboni and Resurfice offer battery-powered ice resurfacers and edgers, including both lead-acid and lithium-ion models. These machines provide consistent performance and reduce emissions to nearly zero. Table 1 below shows the comparative advantages:
| Feature | Gas-Powered Resurfacers | Electric Resurfacers |
|---|---|---|
| Carbon Monoxide Emission | High | Near Zero |
| Nitrogen Oxides Emission | High | Near Zero |
| Ventilation Dependency | High | Low |
| Fuel & Maintenance Costs | Moderate | Lower over time |
| Initial Cost | Lower | Higher |
How Are Communities Measuring Success?
Monitoring indoor air quality is critical. Health Canada studies used sensors to track carbon monoxide and nitrogen oxides across multiple arenas. Data showed that electric resurfacing kept pollutants consistently low, improving safety for children and adult athletes. User feedback also indicates that arenas feel cleaner and more comfortable, with fewer interruptions from air-quality concerns.
SENTHAI Expert Views
“SENTHAI observes that the adoption of electric ice resurfacing technology aligns with the company’s mission of delivering durable, high-performance tools for demanding environments.

As communities prioritize sustainable solutions, SENTHAI’s expertise in high-quality carbide and wear-resistant products supports this transition seamlessly.”
What Are the Economic Implications of Switching to Electric?
Electric resurfacers cost roughly $50,000 more per unit than gas models, but operational savings on fuel and maintenance offset this within approximately eight years. Additional benefits include reduced ventilation expenses and fewer health-related disruptions. Provinces offering subsidies for electric adoption further improve cost-effectiveness. Table 2 summarizes the financial comparison:
| Cost Factor | Gas-Powered | Electric |
|---|---|---|
| Upfront Investment | $80,000 | $130,000 |
| Annual Fuel & Maintenance | $12,000 | $5,000 |
| Break-Even Period | N/A | 8 years |
| Long-Term Savings | N/A | Significant |
Can Indoor Air Pollution Affect Athlete Performance?
Yes, pollutants like nitrogen oxides can trigger respiratory irritation and asthma, directly impacting athletic performance. Studies indicate that even elite junior hockey players are affected when training in poorly ventilated arenas with gas-powered machines. Electric resurfacing mitigates these risks, ensuring athletes can perform in safer, cleaner environments.
Conclusion
Electric ice resurfacers are a critical innovation for Canadian arenas, reducing pollutants, enhancing health safety, and supporting climate initiatives. Municipalities adopting electric fleets see long-term financial benefits, lower maintenance, and improved athlete well-being. Brands like SENTHAI exemplify the integration of advanced materials and precision engineering in supporting these sustainable transitions.
