REALice Ice Making System
REALice System PNE Ice Arenas ! PNE Currently has Two Ice Arenas in Operation ▪Coliseum (16,000 seating capacity and home of the Vancouver Giants from September to April) ▪Agrodome (3500 seating capacity and used for Community Ice from September to March) ! REALice Fortis BC Pilot Program (November 2013) REALice System was installed in the Agrodome instead of the Coliseum ▪Agrodome has 10 times more ice use than the Coliseum (more hot water floods with Zamboni and energy saving potential) ▪Agrodome hot water system could not keep up with shower water demand for user groups when Zamboni required hot water for ice floods (building was not originally designed as a Community Ice facility)

REALice System ! Energy Demand for the Agrodome before the REALice System ▪Zamboni 520 has a 200 US Gallon tank (approx. 150 US gallons of hot water used per ice flood) ▪Zamboni averaged 12 ice floods/day or 2160 ice floods/year which equated to over 324,000 gallons of hot water previously used per year ▪Hot water for ice floods was previously between 120 and 140 degrees F ▪Ice temperature set point was 18 degrees F
Agrodome Domestic Hot Water System
REALice System ! How Things Have Changed Using REALice ▪Community Ice User groups have requested less ice floods due to a more durable ice surface ▪Icemakers use only cold water for ice floods (45 degrees F) instead of hot water (120 to 140 degrees F) ▪Ice temperature set point increased to 21 degrees F (instead of 18 degrees F)
Agrodome REALice Zamboni Filling Station
REALice System Additional Advantages & Costs Savings due to Installation of REALice System ! ▪Ice System compressors have approximately 25% less run time ▪Hot Water Boilers have approximately 50% less run time ▪Community User Groups consistently have hot water for showers ▪Ice System Compressors and Hot Water Boilers have an increased life expectancy ▪Reduced Hydro and Natural Gas utility costs
REALice System Transition Process and Starting to Work With REALice System ! ▪Ice specs and equipment run times were logged prior to REALice System being installed for future comparison purposes (December 2013) ▪PNE staff installed REALice System and monitoring equipment (December 2013) ▪“Old” ice was shaved out (approx. 1”) and REALice was installed between December 23 and 27, 2013 when no ice users were in the building ▪User groups commenced using REALice on January 2, 2014 ▪Ice Techs slowly decreased ice flood water temperature and increased ice temperature set points until optimum ice conditions were obtained ▪Ice Techs adjusted Zamboni speed during ice floods
REALice System Perception from Stakeholders ! ▪Initial reaction from Ice Techs regarding the installation of REALice System was mixed ▪After REALice transition period Ice Techs are now convinced that REALice system makes a clearer and more durable ice surface ▪Ice Plant Operators immediately noticed less equipment run time ▪Management looking for ways to reduce energy use were very pleased with the results ▪Feedback from Community Ice user groups has been very positive commenting that the ice quality is excellent
