Due to the rising cost of copper, aluminum, galvanized steel and fuel, Century Refrigeration, Pryor, Okla., has announced a price increase of 4.90 percent effective June 20, 2008.

“The price of diesel increased both inbound and outbound freight, and all metals used in production have increased between 12 percent and 30 percent since the beginning of the year,” said Vice President of Sales Kevin Trowhill. “This is a common experience in both our business and personal lives as evident by what we pay at the pump.”
