When the condenser uses water while the outside temperature is below freezing, the water freezes on the blowers and on the belts of the motor that drives the blowers. This usually results in the belts breaking and the blowers having one to two inches of ice on them. This problem happens about six to eight times per year. When it happens, we have to take a large torch to the condenser to thaw out the motor and the blowers. Then we need to replace the three belts that drive the blowers. The freezing usually occurs at night when the outside temperature drops below freezing. This results in someone having to come in to make these repairs. Being that it is dark, icy and that we have to use a ladder to get to the frozen area of the condenser it creates an unsafe situation for staff members. The best solution to eliminate this problem is to purchase and install a new Condenser. The Condenser would be sized so that water wouldn't be needed when the outside temperature is below freezing. Attached are three quotes for a new Condenser for the ice plant. The quote from Commercial Refrigeration, $24,660.00 is the lowest quote and is substantially lower than the $35,500.00 that was in the C.I.P. a few years back. This is mostly due to the fact that Commercial Refrigeration will already be on site installing the Barn's rink floor and will not have the overhead costs associated with installing the Condenser from scratch. Another item of importance is the Backpressure Regulator. The Backpressure Regulator would allow more heat to enter through the heat reclaimer that is used to melt the snow in the snowmelt pit. Cm-rently the snow that is dumped in the pit builds up during busy times, causing the need to melt the pit in alternative ways such as moving the snow to other areas of the pit by using a shovel or by using hot water to melt the built up snow. This project was originally scheduled for 2000. However, due to the heat exchanger in the furnace going out to the Barn, the money was used on that project and the Backpressure Regulator was moved to 2005. With the new floor in the Barn being installed this year, it would be cost effective to install the Backpressure Regulator this year. Commercial Refrigeration will be on site installing the floor, making it less expensive for them to install the Backpressure Regulator. Attached is Commercial Refrigeration's quote to install the backpressure regulator. In the Capital Improvement Plan, the estimated cost of the backpressure regulator is $3,300.00. Commercial Refrigeration's quote is $2,213.00 if we install it during the construction of the Barn's floor, saving close to $1,100.00 compared to what was budgeted for the project in 2005. I'm available to discuss this further if needed, please give me a call at the Arena.
