SDS DATE OF PREPARATION/REVISION: 09/24/15
Tubes are filled with water, and hooked up to a “chiller” which cools the water down to -9 degrees Celcius (15F) and pushes it through the tubes. A mixture of 60% Anti-freeze and 40% water runs through the chiller, much like a like a big air conditioner; taking heat away from the liquid, cooling it off, and the tubes get cold enough to freeze the rink.
