We’ll take you through the science and history of ice making in hockey arenas, so you can better understand and appreciate the work that goes into creating the perfect ice surface for the game of hockey.

The Process of Making Hockey Ice

Ice making is a meticulous and technical process that ensures the safety and performance of ice surfaces for hockey games. The process starts with water purification, where all impurities are removed from the water to ensure that the ice produced is of high quality. After that, the water is frozen in a chiller plant, which maintains a temperature of -8 to -10°C to allow for the formation of crystal-clear ice. The resulting ice slab is then transferred to the ice resurfacer, where it is planed, shaved and washed to create the ideal playing surface.

However, making ice is not a one-time process. The ice must be regularly maintained to ensure that it remains flat, hard, and free of scratches and cracks. The ice maintenance process involves the use of special equipment and techniques, such as the ice resurfacer and ice edger, to maintain the ice’s integrity. Ice technicians must also constantly monitor the ice temperature and humidity levels to make adjustments as needed to ensure optimal ice conditions.

Temperature control is another crucial aspect of ice making in hockey arenas. The ideal temperature range for the ice surface is between -5 to -7°C, with the temperature being controlled by the chiller plant. Additionally, the temperature and humidity levels in the arena must be carefully managed to ensure the ice surface remains solid and free of condensation, which can negatively affect game play.

The role of humidity in ice formation is also an essential consideration in the ice making process. When the humidity is too high, it can result in a soft, wet, and slushy playing surface, which can be dangerous for players. To maintain optimal ice quality, arenas use specialized dehumidification systems to reduce the moisture content in the air.

Water Treatment for Ice Making

  1. Water Source: The first step in making ice for a hockey arena is to ensure a reliable water source. Municipal water is the most commonly used source, and it must meet specific quality standards.
  2. Pre-Treatment: Before the water can be used to make ice, it must undergo pre-treatment. This includes the removal of impurities such as sediment, dissolved minerals, and organic matter that can affect the quality of the ice.
  3. Chlorination: Once the water is treated, chlorine is added to control bacteria growth. It is crucial to maintain the proper chlorine levels, as too little or too much can lead to problems with the ice quality or safety.
  4. Reverse Osmosis: In some cases, reverse osmosis is used to further purify the water. This process removes dissolved minerals and other contaminants that may negatively impact the ice’s clarity and hardness.

In summary, water treatment is an essential step in creating the high-quality ice needed for hockey arenas. By ensuring a reliable water source, pre-treating the water, adding chlorine, and potentially using reverse osmosis, ice technicians can create the ideal conditions for the ice to form and maintain the integrity of the playing surface.

Layering the Ice Surface

After the first layer of ice has been made, subsequent layers are built on top to create a smooth, level surface. Each layer of ice is made using a process called flooding, where a thin layer of water is spread evenly over the surface using a hose or sprinkler system.

Once the layer has frozen solid, the process is repeated until the ice is the desired thickness. The thickness of the ice can vary depending on factors such as the level of play, temperature and humidity.

Between each layer, the ice is pebbled, which involves using a machine to score the surface of the ice, creating a rough texture that helps the next layer bond to the previous one.

Once the final layer is applied and frozen, the ice is ready for skating. However, before it can be used, it needs to be trimmed and painted, which involves using a machine to shave off the top layer of ice and then paint lines and logos onto the surface.

Ice Maintenance in Hockey Arenas

Maintenance Schedule: To ensure optimal playing conditions, ice surfaces must be maintained frequently. Generally, maintenance is performed before and after each practice or game. This includes cleaning the surface, shaving off thin layers of ice, and flooding the rink with hot water.

Equipment: Specialized equipment is used to maintain ice surfaces, including a Zamboni or ice resurfacer. These machines scrape off a thin layer of ice and apply hot water to the surface, smoothing it out and filling in any cracks or crevices.

Snow Management: As ice is resurfaced, a build-up of snow occurs. This snow must be removed from the ice surface and rink area to prevent damage to the ice and ensure safe playing conditions. The snow is typically collected in a snow dump outside the arena.

Temperature Control: The temperature of the arena is carefully regulated to maintain the integrity of the ice surface. Temperature sensors are used to monitor the temperature of the ice, and the building’s heating and cooling systems are adjusted accordingly to keep the temperature at an optimal level.

Ice Quality: The quality of the ice is crucial to a safe and enjoyable playing experience. Maintenance personnel regularly test the ice for hardness, texture, and other factors to ensure it is of the highest quality.

Zamboni Maintenance

Regular maintenance of the Zamboni machine is crucial for keeping the ice surface smooth and even. Oil changes, filter replacements, and blade sharpening are all important parts of Zamboni maintenance.

Failure to maintain the Zamboni can result in uneven ice, debris buildup, and damage to the ice surface. Regular maintenance ensures that the machine runs smoothly and creates a clean, smooth ice surface.

Zamboni maintenance also involves cleaning the machine thoroughly after each use. This includes emptying the water and waste tanks, cleaning the blade and squeegee, and wiping down the entire machine to prevent rust and corrosion.

Most arenas have a Zamboni maintenance schedule that outlines specific tasks and intervals for regular maintenance. This helps ensure that the machine is kept in good condition and reduces the risk of breakdowns during use.

Ice Resurfacing Techniques

Hot Water Flood Method: In this technique, hot water is spread over the surface of the ice, melting the top layer and creating a smooth surface. This method is time-consuming, but it provides the best results.

Shaving Method: In this technique, a sharp blade is used to shave off the top layer of ice and collect it in a tank, followed by spreading a thin layer of hot water over the surface to create a smooth finish. This method is faster than the hot water flood method but does not provide as much control over the ice surface quality.

Spray Method: This technique involves spraying hot water over the surface of the ice, which creates a thin layer of new ice. The spraying process is repeated until the desired smoothness is achieved. This method is quick and efficient but may not provide the same level of surface quality as the other two methods.

Combination Method: This technique involves a combination of the above-mentioned methods, depending on the condition of the ice surface and the time available for maintenance. The combination method can be used to create the best possible surface quality in a shorter amount of time.

Temperature Control in Hockey Arenas

Ice quality and temperature control are important factors in ensuring a safe and enjoyable game for both players and spectators.

Typically, the temperature inside an arena is kept between 50°F to 65°F (10°C to 18°C) during game times, and slightly warmer during non-game times.

To maintain optimal ice conditions, it is important to monitor both the air and ice temperature throughout the day, as well as humidity levels.

Air Temperature Control

Temperature Control: Maintaining the ideal air temperature is crucial in creating the best ice surface for hockey. The recommended temperature for ice rinks is between 50-60 degrees Fahrenheit.

Air Flow: Air flow is essential to help cool the ice and to distribute the moisture during the resurfacing process. Without adequate air flow, the ice can become uneven and create soft spots.

Humidity: Maintaining a low humidity level in the arena is also critical to achieving high-quality ice. High humidity can lead to soft and slushy ice that can affect the speed and quality of the game.

Ice Temperature Monitoring

Thermometers: Temperature monitoring is a critical component of maintaining an optimal ice surface for hockey games. Thermometers are used to measure the temperature of the ice surface to ensure that it is within the desired range. A digital thermometer is commonly used for this purpose.

Ice Surface Temperature: The ideal temperature for an ice surface in a hockey arena is between 22-26 degrees Fahrenheit. If the temperature is too high or too low, the ice may become too soft or too hard, resulting in poor skating conditions and a suboptimal game experience for players and fans.

Regular Monitoring: To maintain an optimal ice surface temperature, regular monitoring is necessary. The ice temperature should be monitored throughout the day, especially during times of high traffic, to ensure that it stays within the desired range. This can be done manually or with the help of automated temperature monitoring systems.

Effects of Climate on Ice Quality

Temperature is one of the most critical factors affecting the quality of ice in a hockey arena. The optimal temperature for maintaining high-quality ice is between 18 and 21 degrees Fahrenheit. Humidity is another significant factor that affects the quality of the ice. High humidity levels can lead to soft, slushy ice, while low humidity levels can result in brittle, hard ice that easily chips.

Sunlight can also affect ice quality in outdoor arenas. When exposed to direct sunlight, ice can become soft and slushy, making it difficult to skate on. On the other hand, when temperatures drop below freezing, ice can become too hard and brittle. Finally, wind can cause the ice to dry out, leading to cracks and an uneven surface.

Given these factors, it’s essential to monitor weather conditions and adjust temperature and humidity levels in the arena accordingly. Failure to do so can result in subpar ice quality, leading to an increased risk of injury to players and a subpar experience for spectators.

The Role of Humidity in Ice Formation

Humidity plays a crucial role in ice formation and maintenance in hockey arenas. High humidity levels can make it difficult to maintain a hard, smooth ice surface, as excess moisture in the air can lead to soft and slushy ice.

Ice resurfacing machines are used to remove the top layer of the ice and add a fresh layer of water to create a smooth, level playing surface. However, if the humidity is too high, the new layer of water can take longer to freeze, resulting in uneven ice and delaying the resurfacing process.

Dehumidifiers are commonly used to regulate humidity levels in hockey arenas. These machines work by removing moisture from the air, which helps to create a dry environment and maintain a hard, fast playing surface.

Humidity Control Techniques

Dehumidification Systems: Installing a high-quality dehumidification system in the hockey arena is one of the best ways to control humidity levels. It helps to maintain the desired humidity level, which ultimately leads to better ice quality.

Air Circulation: Proper air circulation is essential to control humidity levels in the arena. The air conditioning system should be designed in a way that circulates the air uniformly throughout the arena. This ensures that the moisture content is consistent throughout the arena.

Ventilation: Proper ventilation is also crucial in controlling humidity levels in the arena. The arena should be equipped with proper exhaust fans to remove the humid air and replace it with fresh, dry air.

Environmental Considerations in Hockey Arenas

Sustainability: With increasing awareness of climate change and environmental impacts, the focus has shifted towards making hockey arenas more sustainable. Using renewable energy sources such as solar, wind, or geothermal can significantly reduce the carbon footprint of the arena.

Water conservation: Hockey arenas consume a large amount of water for maintaining the ice surface, cleaning, and other purposes. Implementing water conservation measures such as low-flow fixtures, efficient ice resurfacing machines, and recycling water can reduce water consumption.

Waste management: Hockey arenas generate a significant amount of waste from food and beverage containers, paper products, and other materials. Implementing effective waste management strategies such as recycling, composting, and reducing the use of disposable products can help reduce waste and promote sustainability.

Energy Efficiency Measures

LED Lighting: One of the simplest ways to reduce energy consumption in hockey arenas is by installing LED lighting. These lights consume less energy and have a longer lifespan than traditional incandescent or fluorescent bulbs. Moreover, they do not produce as much heat as traditional lights, which can help to reduce the load on cooling systems.

Energy-efficient HVAC systems: Heating, ventilation, and air conditioning (HVAC) systems are some of the biggest energy consumers in hockey arenas. Energy-efficient HVAC systems can help to reduce energy consumption and lower energy costs. These systems use less energy to maintain a comfortable temperature in the arena and can be controlled to match occupancy patterns, thereby reducing energy waste.

Solar panels: Solar panels are a renewable energy source that can be installed on the roof of the arena to generate electricity. The electricity generated can be used to power the arena’s lighting, HVAC, and other systems. While the initial investment in solar panels can be expensive, they can provide significant long-term savings in energy costs.

Water Conservation Practices

Low-Flow Fixtures: Installing low-flow toilets, sinks, and showerheads can help conserve water. These fixtures use less water without affecting their performance. They are a cost-effective solution that can save significant amounts of water over time.

Recycling Greywater: Greywater is wastewater from sinks, showers, and laundry. It can be treated and reused for non-potable purposes such as irrigation, flushing toilets, or cleaning. Recycling greywater can significantly reduce water usage in hockey arenas.

Ice Maintenance: Ice maintenance practices can have a significant impact on water usage. Using a water management system can help monitor and control water usage during resurfacing. Furthermore, implementing an effective ice-making system can help reduce water wastage and conserve resources.

Waste Management Strategies

Managing waste is an important consideration for any facility, and hockey arenas are no exception. The amount of waste generated by a single game can be substantial, from empty food containers to discarded equipment. To address this issue, arenas can implement recycling programs to divert as much waste as possible from landfills.

Another effective strategy is to focus on source reduction by minimizing the amount of waste generated in the first place. This can be achieved by implementing policies such as banning single-use plastics and encouraging fans to bring reusable water bottles and containers.

Finally, arenas can also implement composting programs to divert organic waste from landfills and create nutrient-rich soil for landscaping and other uses. By adopting these waste management strategies, hockey arenas can reduce their environmental impact and promote sustainable practices.

History of Hockey Ice Making

The origins of making ice for hockey rinks date back to the late 19th century, when natural ice was used for outdoor rinks. However, with the advent of indoor arenas, there was a need for a more reliable and efficient ice making process. The first successful artificial ice rink was built in 1876 by John Gamgee in England using a process that involved refrigeration and a steam-powered compressor.

Over the years, various improvements were made to the ice making process, such as the use of ammonia-based refrigeration systems and brine solutions to cool the ice surface. The use of refrigeration systems became widespread in the 1920s and 1930s, and by the 1950s, nearly all indoor rinks were using artificial ice.

In the 1970s, advancements in technology led to the development of more energy-efficient refrigeration systems and the use of ethylene glycol instead of brine solutions. Additionally, rinks began experimenting with different types of ice surfaces, such as concrete or sand-based surfaces, to provide better ice quality.

Today, ice making technology continues to evolve, with the focus on improving ice quality, energy efficiency, and environmental sustainability. Some rinks are even experimenting with using alternative refrigerants, such as carbon dioxide, in their ice making systems.

Early Ice Making Techniques

Before the invention of modern ice making technologies, natural ice was harvested from frozen lakes and ponds in the winter. It was then stored in ice houses, where it could be used for several months. In the mid-19th century, artificial ice began to be produced using ammonia refrigeration systems, which were used to cool brine solutions that were then used to freeze water in large tanks.

Another early ice making technique was the use of ice plows, which were horse-drawn devices that cut blocks of ice from frozen bodies of water. The blocks were then transported to ice houses where they were stored for later use. These methods were slow and labor-intensive, making it difficult to produce enough ice to meet the growing demand.

In 1876, the first commercial ice-making machine was patented by a man named Carl von Linde. The machine used a compression refrigeration system to cool ammonia, which was then used to freeze water in a separate compartment. This new technology revolutionized the ice industry and made it possible to produce ice on a large scale.

Modern Ice Making Innovations

Refrigeration Technology: In the early 1900s, refrigeration systems replaced natural ice-making techniques. Modern refrigeration systems use ammonia and glycol as coolants, which are circulated through pipes beneath the ice surface to maintain the necessary temperature.

Computerized Control Systems: Today’s ice making systems utilize computerized control systems to monitor and adjust temperature, humidity, and ice thickness. These systems can also adjust ice surface conditions to accommodate different sports and events.

Energy Efficiency: Modern ice making systems are designed to be energy-efficient to minimize operating costs and reduce environmental impact. This is achieved through various techniques such as heat recovery, variable speed drives, and thermal storage systems.

Ice Maintenance Equipment: Advancements in ice maintenance equipment have also contributed to the quality of ice surfaces. Equipment such as ice resurfacers, scrubbers, and edgers help maintain the integrity of the ice surface and ensure it remains smooth and level.

Impact of Technology on Ice Making

Advancements in technology have revolutionized the way ice is made in hockey arenas. Computerized ice-making systems now control the temperature, humidity, and water flow to produce high-quality ice. This has led to increased energy efficiency and lower operating costs for arenas.

Another technology that has made an impact is laser leveling systems. These systems use lasers to measure the height and slope of the ice surface, ensuring that it is even and meets NHL standards.

Ice resurfacing machines have also improved with technology. New machines are now faster, quieter, and more fuel-efficient, reducing the time and energy required to resurface the ice between periods.
