  • Page 16: Operation

    Operation POLAR-PAK Refrigeration Systems utilize a draw-through design. The walk-in air is drawn into the air in-take vent(s) and the evaporator coil prior to becoming discharged into the walk- in. This circulation becomes a vehicle for transporting the unwanted thermal load into the evaporator coil for rejection to the ambient air.
