WHAT MAKES A GOOD BLAST CELL? 1. 1. Bla last Temperature and Refrigeration • Cells need appropriate refrigeration capacity to remove product heat load 2. 2. Bla last Air irflow • Cells need appropriate structural design for consistent, evenly-distributed airflow to cool all product within a cell Lineage Logistics | 10
