PHILADELPHIA -- It was show-and-tell time for Dan Craig, the NHL's resident ice-making guru.
During the general media availability at 3:30 Monday afternoon, Craig ran over and grabbed one of the four-inch pipes that he will use to connect the floor of the auxiliary rink to the refrigeration truck parked outside Citizens Bank Park. He picked it up and began explaining how it connects to the floor and how the pipe eventually connects to the truck outside.
"We hook the (aluminum panels) onto these hoses," Craig said, pointing out the hoses attached to the pipe. "There's a quick connect here and the glycol, which is simple antifreeze, gets pumped into the aluminum panel, which is a quick, fast-freezing element. The whole set up will take about 300 panels, and these are 30 feet long by 30 inches wide. We'll push 1,500 gallons of glycol in per minute from the truck down into the floor."
Craig had the assembled media amazed. It was one of those, "Wait a minute, you don't just spray water and it freezes" moments.
It definitely is not, and that's why Craig pulled out one of the pipes to demonstrate.
Other than the show-and-tell, Craig offered some positive updates for how the first day of the 2012 Bridgestone NHL Winter Classic buildout was going. He said everything is on schedule and going according to plan.
The plan for Tuesday is further set-up and the goal is to be spraying water by Thursday night. He said it'll happen at night because the sun goes down and the temperatures dip into the 30s, and those are ideal conditions for ice making.
"We might as well use the benefit of being down into the 30s or high 40s to make a good sheet of ice," Craig said. "So, if you go onto the (NHL.com) webcam, you won't see a whole lot of work going on during the day. A lot of it will happen at night with security lightning because that's the best time for us to work."
Once Craig was finished with his demonstration and update, he started fielding some questions. A television reporter asked him about the challenges he faces here at Citizens Bank Park compared to other outside venues.
"I don't know yet. I really don't," Craig said. "It's one of those things you have to be in here for a couple of days. This morning it was very calm, very nice, and now we have the wind picking up, and it's approximately gametime for us. That's one of the things I watch, is to really see what transitions here between noon and 4, what happens in the region and how it affects us here. If you get up to the truck you don't feel the wind, but down here you feel the wind. It's elements like that that we have to play with and work with."
The goal, Craig said, is to have an inch of ice built by Dec. 26 so they can start painting white Dec. 27. He wants to have the lines and logos painted on the 28th and then build more ice so the entire sheet is ready before the scheduled media skate on Dec. 30.
Craig was asked if it's important that the ice gets skated on prior to the actual game being played on Jan. 2.
"Definitely, definitely," he said. "It doesn't matter where you are or what facility you're in, you always try to make sure it's chewed up a little bit so we can let it heal itself and get the bottom back together. Density on a sheet of ice is the No. 1 thing we deal with."
With no further questions, Craig's first general media session was over. He walked away smiling as he went to tackle his next task.
