Auto Pressurization System (APS)

With the I J White Auto Pressurization System (APS), your blast freezer could look like this

By combining innovative air pressurization technology with a unique distribution design, the Auto Pressurization System (APS) automatically balances the pressure different 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.

With this system, blast freezers can 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%.
