Rytec’s Angermeier says most of the energy saved comes from how well the freezer is sealed off. Rytec’s Turbo-Seal Insulated has a 1-inch thick insulated panel with a Rilon inner core, closed-cell foam outer layers and no heat-sealed pockets, stitching, spun insulation or quilted pads.
“The door saves so much energy, it’s virtually free,” says Angermeier. “In two years the door will pay for itself. It’s alarming when people find out how much they’ve wasted with their current doors that allow cold air to go down the dock and right out the window.”
The cold storage and food distributor sector can greatly benefit from energy saving doors, and all the major door manufacturers can help you calculate the ROI.
