Humidity Management and Your ROI

Published: June 26, 2025

FPG refrigerated cabinets are engineered to retain humidity. Why? Because it impacts your ROI.

A natural consequence of refrigeration is the removal of moisture. It’s an issue for fresh food held in refrigerated display cabinets. Food dries out. Shelf life is reduced. Customers are disappointed.

Conversely, high humidity inside refrigerated display cabinets contributes to ROI.

SAVE MORE: High levels of humidity decrease operational costs by:

  • Extending shelf life and reducing food wastage
  • Increasing the efficiency of the refrigeration system
  • Increasing energy efficiency

SELL MORE: High levels of humidity increase sales by:

  • Extending shelf life
  • Making food look attractive
  • Improving the customer experience when they eat your products and encouraging repeat customers

FPG has engineered a solution to retain moisture throughout the refrigeration cycle. Cooled humid air is cycled into the cabinet display area. The results of FPG’s humidity management are revealed in FPG’s tests of cabinets which are undertaken in climate-controlled test labs. The test results provide evidence for:

  • Refrigeration system efficiency
  • Energy efficiency
  • Tight temperature management
  • High humidity
  • Gentle airflow

These all contribute to the ROI of a refrigerated food display cabinet, with humidity levels and gentle airflow directly contributing to holding food fresher for longer.

The following graphs show the high internal humidity and gentle air flow measured during the testing of a new FPG refrigerated food display cabinet:

The combination of high humidity and low air speed inside the cabinet means cold food is held fresher for longer. How much longer depends on a wide range of variables such as product ingredients and operational practices. The best way to determine this is to try FPG cabinets for yourself.
