Hockey can be one of the toughest sports when playing on surfaces. The speed of the game, along with quick movements one way, sharp stops, and powerful shots on the ice, creates incredible work on the surface. Arenas must examine every aspect of their ice as they strive for optimal performance. Ice maintenance isn’t just about keeping the rink cold—it’s a fine-tuning process that requires resurfacing and constantly regulating temperature, humidity, and rink conditions.
The quality of the ice impacts every element of the game, such as how quickly the players can skate and how easily the puck moves on the surface. Irregularities and imperfections in the ice can, in turn, affect the flow of play, player safety, and game dynamics. In this guide, we look at how hockey arenas maintain good-quality ice to ensure they have the best ice possible for games.
It takes far more than freezing water to maintain ice. It’s a complex process that requires a thorough understanding of the interplay between temperature, humidity, water chemistry, and player activity. The main objective is to maintain the ice properly, hard, smooth, and without defects, such as cracks or chips, during the game time. Ice that is too soft for skating will slow the puck and make it harder to skate, albeit with more grip. Ice that is too hard can be brittle and start cracking.
The ice maintenance process at hockey arenas starts long before the first puck drops. The rink floor—usually a solid, concrete, or metal surface—is cooled by refrigeration systems that circulate glycol or other cool liquids. Water is then sprayed in thin layers, each freezing before the next is applied. These layers build up over time until the ice is the thickness they want, typically between 1 and 1.25 inches. After all the ice has been made, routine maintenance will be essential to maintain its quality.
Central to this are the adaptations of the rink conditions resulting from numerous factors, including the wear and tear on the ice during a game, the density of people who occupy the arena during its history, and outside conditions that may penetrate the indoor environment. Ice maintenance is important to ensure the ice surface is consistent, safe, and conducive to high-speed play.
The most famous ice-maintaining machine is the Zamboni. This ice resurfacing machine, named after the inventor Frank Zamboni, is vital for maintaining optimal conditions on the rink. Between periods of play, a Zamboni is used to shave down the top layer of ice that has become worn and uneven from skates, puck marks or just the game action. It also scrubs the ice and clears out any loose debris.
After scraping off the top layer, the Zamboni covers the surface with a thin layer of warm water. That water freezes almost immediately, creating a new smooth ice layer. This part, called resurfacing, is important to keep the puck flowing and not catch the players up with dragging pads. The Zamboni does This work in a matter of minutes, enabling the game to continue with minimal delay.
The timing of the resurfacing is done to maximize ice quality and minimize interference with the game. Usually, a Zamboni will resurface the ice during intermissions, but depending on how much the surface wears, more resurfacing breaks might be necessary. Sometimes, the timing of each resurfacing is an art unto itself — too much resurfacing, too much ice, too little, and the ice is rough and dimpled.
Another important factor in ice maintenance is temperature control. This means the ice and the air around it have to be kept at the right temperature so that the rink stays in prime condition. Too-warm ice gets soft and slushy, which melts into difficult skating surfaces for players and sticky surfaces for the puck. Ice that is too cold, conversely, is too hard and brittle and breaks more under the stress of the game's play.
Ideally, arenas keep the ice at around 24°F (-4°C) to 26°F (-3°C) for optimum conditions. This range spec is to hard enough to sustain the abuses of a hockey game, but soft enough to make for a smooth skating surface.
One of the primary struggles with temperature control is being consistent throughout the entire rink. For example, if an arena has a refrigeration system on one side, you may need to lower the temperature of the surrounding area near floral to help plants last longer. Ice maintenance crews monitor these fluctuations and adjust to them, using temperature sensors embedded in the ice.
Arena staff are responsible for controlling more than just ice temperature. If the air is too warm, it can melt the ice slightly on the surface, a thin layer of water that leads to slow gameplay. On the other hand, if the outside air is too cold, the ice will freeze too rapidly, leading to a rough, bumpy surface.
Another crucial element in maintaining rink conditions is humidity. In winter , high humidity levels can lead to condensation on the ice surface, forming a thin film of water on top that makes the puck seem sticky and tougher to handle. Too much humidity can also cause fog to form over the rink, compromising visibility for players and fans alike.
Hockey arenas use dehumidification systems to achieve this, keeping humidity levels within a more comfortable range of 30-50%, with a lot of moisture generated on the rink itself. Using these systems, moisture is removed from the air , making sure the ice stays dry and that the playing conditions are optimal. In arenas located in warmer climates that can make maintaining low humidity levels more difficult due to outside weather conditions, humidity control is especially critical.
Dehumidification isn’t only about the comfort of the players and spectators—it is one of the main factors that affect the quality of the ice. Plenty of moisture in the air makes the ice softer, which makes the puck move slower and increases the risk of marking the surface with skate marks and divots. Maintaining the humidity at the appropriate level means that your ice will be hard and fast so that the players have the best ice possible.
Keeping a proper rink ready involves more than a Zamboni, temperature, and humidity control. Rink managers also must take into account the number of bodies in the arena, the pace of play, and the players themselves. With more fans in the stands comes more heat in the arena, which can affect the air and ice temperatures. Play that is more intense, likewise, can wear the ice down more quickly and require more frequent resurfacing or adjustments to the temperature control systems.
One of the most underrated aspects of ice is player feedback. When the ice goes bad — too soft, too hard, or too bumpy — it’s usually the players who notice first. This feedback allows the managers to improve their maintenance process and to make adjustments in play if required. By being conscious of the players’ needs, arena staff can keep the ice in top shape all game long.
Everything from Zamboni's performance in resurfacing the ice to how we control the temperature, humidity, and rink conditions - all play an important part in providing the quality of ice necessary for peak performance on game day. Without ice maintenance players would struggle to skate fast, the puck wouldn’t slide, and the game would be fairly slow and boring to watch.
Ice is not only the surface on which the game is played but also a key component of hockey. We nurture a sport, and by learning more about the processes to keep that sport sustainable, we can quantify the effort and importance of the quality of ice to every game.” From dehumidifying the facility to temperature control to periodic resurfacing of the ice during play, proper general maintenance of the rink is essential to ensuring a fast-paced, competitive, and safe game of ice hockey.
