Cottage Grove ice arena study under way
The outdated refrigeration system inside one of the rinks at the Cottage Grove Ice Arena is under inspection.
While the R-22 refrigerant system inside the north and south rink is adequately operating, the arena’s manager, Jordan Hirman, said it has surpassed its life expectancy by 11 years.
In preparation of a mandated phase-out of all R-22 equipment by 2020, the city of Cottage Grove has hired Hudson-based Stevens Engineering to conduct an ice systems evaluation study.
The cost of the study is $4,900.
“This is the first step in moving toward getting in line for a Mighty Ducks grant,” City Administrator Ryan Schroeder said.
The grant, he said, would assist the city in replacing the R-22 system, which he estimated to cost $800,000 to $1 million.
The state-funded grant is distributed by the Minnesota Amateur Sports Commission to assist cities install, renovate or replace heating, air conditioning or ventilation equipment in existing ice arenas.
As part of the study, Hirman said, the engineering firm will provide useful life projections of the current system, analyze replacement options, energy-efficient options, and provide an estimate project schedule and cost options moving forward.
