Air distribution and air movement were of paramount importance because we had to ensure that all coldstore chambers maintained a critical uniform temperature. All areas were thermally mapped at ground, mid and high level utilising numerous data loggers, which provided the client with essential data for analysis and evidence of correct storage. We selected the ZEFIRO evaporators with EC Fans and a 5k TD (and off cycle defrost) for the two main storage chambers to ensure that the air was distributed above the product sat on top of the pallet racking. This had to be low velocity air with a face / air off temperature close to the store temperature to eliminate cold spots. The cold stores were consistently between 3.9 – 4.2’C.
The SCIROCCO condensers with EC Fans were selected to ensure that the required dBA noise levels were not exceeded.
