As part of the MCCAC’s Recreation Energy Conservation (REC) program, the Town of Carstairs installed a REALice system at the Carstairs Memorial Arena.

REALice is an energy-saving de-aerating system for ice rinks. It creates a controlled and structured vortex to remove gases and other particulates such as limescale as water flows through the device. REALice treated water eliminates the need to use heated water when building or resurfacing your ice and reduces compressor loads. The system has no moving parts and is easily integrated into existing piping systems.


This newly installed system will help to reduce the costs of heating the water used to resurface the ice as well as the electricity costs associated with cooling the ice following resurfacing. This system eliminates the need for hot water when building and resurfacing ice by removing micro air bubbles from the incoming water resulting in lower natural gas consumption from hot water heaters and less load on compressors.


This project will save an estimated reduction of 24 tonnes/year of greenhouse gases, reduces emissions from ice making and maintenance by 11% and has a payback time of 2.2 years.

The project was completed in June, 2021.

“The system will reduce the energy consumption for the Carstairs Memorial Arena. The Town was very excited for the opportunity to work with the Municipal Climate Change Action Centre and without this partnership, the project would not have been possible. We look forward to welcoming patrons back in the fall and testing out the technology while reducing greenhouse gases.”
