By combining new European air pressurization technology with a unique distribution design, IJ White’s Auto Pressurization System (APS) automatically balances the pressure differential at the infeed and discharge openings on spiral blast freezers. PLC controlled and monitored, the system reduces the amount of cold freezer air spilling from the low opening and controls warm, moist air infiltration from entering into the blast freezing system. APS helps blast freezers dramatically increase the production time between coil defrosts. Due to the minimal cold air spillage, employees are able to work near the freezer in comfort. APS reduces energy costs and has proven to increase production efficiency by more than 32 percent.
