Eliminating Costly Humidity Problems in a High-Volume Warehouse

A leading British footwear manufacturer, known for durable, handcrafted products, was facing a growing operational threat inside its primary storage warehouse. Moisture levels were rising, and mould was forming on finished stock. Every damaged pair represented:

  • Lost revenue
  • Unpredictable stock availability
  • Operational disruption during a peak production period

For an operation with tight seasonal targets, this was not just a quality issue, it was a supply chain and fulfilment risk.

The Root Cause

Temperature Stratification Driving Excess Humidity

During our site survey, Inergy Group identified that the warehouse was experiencing significant temperature variation. Warm air was trapping at high level while lower areas remained too cool. This imbalance created:

  • Hot and cold pockets across the racking aisles
  • Poor air movement
  • High relative humidity at product level
  • A perfect environment for mould growth

This meant the HVAC strategy was not only underperforming, but it had a direct impact on stock integrity and output.

1. High-Efficiency Electric Air Heaters

  • Provide fast, controlled heating
  • Deliver stable, evenly distributed temperature across the warehouse

2. Industrial De-Stratification Fans

  • Continuously pull warm air from the roof space and redistribute it downward
  • Remove hot/cold pockets
  • Improve overall air movement and humidity control
  • Allow heaters to run less frequently → lower energy usage and reduced operating cost

Correct positioning was essential due to tall rack storage. We engineered custom brackets and layouts to ensure optimal airflow throughout the space.

The Operational Impact

Immediate Improvement, Long-Term Protection

The results were felt on day one:

  • Warehouse staff instantly noticed a more consistent and comfortable temperature
  • Temperature and humidity levels stabilised across all storage zones
  • Mould formation stopped completely
  • Full warehouse capacity was restored
  • The operation can enter the winter season with confidence, not risk

For this manufacturer, the solution did more than fix a humidity issue—it protected inventory, strengthened operational performance, and ensured product availability during critical trading periods.
