This project is included in the 2007 Capital Improvement Program (CIF). The projects include the replacement of the arena refrigeration floor piping, dasher boards and glass, evaporator condenser; and re -insulating the chiller barrel. To maximize the use of this equipment, these projects have been delayed for several years based upon a close evaluation each season. Following is the age of the existing equipment as well as the Iife expectancy of each: item Year Installed Expected Life Refrigeration Floor 1979 20 years Boards and Glass System 1982 20 years Condenser 1998 (used) 5-10 years from install Chiller - Receiver 1979 15-20 years At the September 18th, 2006 meeting the City Council suggested staff study the geothennal technology further as it applies to ice arenas. Preliminary indications were that it was not practical to do in our refurbish situation. Staff has since visited two new geothermal ice rinks, gathered further information and has been in communication with Hardy Mechanical, a company that specializes in geothermal technology. All rinks using this technology are newly constructed and have a higher initial installation cost. There are currently no retrofit rinks in operation at this time.
