Cold Storage Humidification


Cold air is unable to hold as much moisture as warm air. As ambient air enters a cold store the air temperature reduces and the moisture falls out condensing onto cold surfaces and the refrigeration coils. Although the air has a high relative humidity the actual moisture content is quite low.

The warmer ambient air absorbs moisture from the produce within the cold store which leads to weight loss and in turn financial loss. In addition a lack of correct humidity results in a poor quality product with reduced shelf life and the risk of disease developing.

To avoid such a situation the installation of a humidity system controlled by a humidistat within a closed loop system would maintain the desired humidity level at all times without over wetting the produce and other surfaces.
