The useful life of wood dasher board systems depend on the maintenance, timeliness of the <br />repairs and the amount of moisture in the ice arena and therefare can be difficult to determine <br />Wood dasher board systems are not commonly found in arenas today and are no longer <br />manufactured. They have becn replaced with steel and aluminum framed systems. <br />An estimated cost far a new dasher board system is included in Table 1 below. The cost estimate <br />is based on removing the existing dasher board system and furnishing and installing a new <br />aluminum or steel framed dasher hoard system that includes the following: <br />* aluminum ar steel frame; <br />i polyethylene board facing, kickplate and caprail; <br />■ polyethylene backer panels on each end of Rh� rink; <br />+ te�npered glass supparl�ess spectatar shielding on both side of rink; <br />� typical tempered glass suppa��ted shielding with protective netting on each end; <br />� equipment, player and access gates; <br />t safety pads on t nds of shielding; <br />+ players, penalty and timekeepers boxes, raised floars, rubber floaring and benches. <br />The cost of the system will vary depending on the amenities and quality of materials desired and <br />time of bidding. Some options to consider that are not included in the cost estimate are I� f[ out <br />end panels far soccer net installation, netting on bleacher sides of rink, and a flexible glass system <br />� (currently only offered by Athletsca}. <br />— Table 6.

The RSVC rink is served by a direct type refrigeration <br />system and ice rink floar. Direct refrigeration systems circulate refrigerant (R-22 in this case) <br />throughout the rink floarto provide the cooling required to maintain the ice sheet. These types of <br />systems were very common in the 1970's and early 1980's. Today, indirect refrigeration <br />systems, where glycol and calcium chloricl� solutions are circulated in the rink floor, are mare <br />common. <br />There are two main reasons far the increased popularity of indirect refrigeration systems. They <br />are less expensive to install and do not require refrigerant to be circulated in the arena space were <br />spectatars are seated. Environmental concerns are a third reason far their popularity since <br />indirect systems use much less refrigerant than direct systems. However, indirect systems are less <br />efficient to operate than direct systems by as much as 30% in some cases. One Minnesota Ice <br />Rink Facility saves as much as $1,000 per month in utility costs on the operation oftheir direct <br />system on Rink 1 over the operation of their indirect system on Rink 2. <br />9� <br />
