Your Blast Freezer before using IJ White’s Ultra Series Auto Pressurization System (APS) System

This is what your freezer looks like before using the IJ White Ultra Series Auto-Pressurization System (APS). APS reduces moist air infiltration that migrates into the Blast Freezer and helps keep the Refrigeration Coils free longer from ice and snow build-up. Saves energy and reduces maintenance costs.
