1. Introduction

TCe is an ecological humidity absorber and all that is needed to get your cargo dry and protect it against any damage related to condensation and humidity in a controlled environment. It effectively prevents condensation and reduces moisture. Each pole has an extensive capacity and collects up to 2,6 litres of water. It takes not much loading space while it fits in the recesses of the corrugated container walls. The cost is low, even compared to other less efficient alternatives.

  • 2. How it works

    The capacity of the air to absorb vapour depends on the temperature and the relative humidity. If the temperature is lowered while the humidity is held constant, the air can not hold the same amount of vapour. This leads to that water condense on the inside of the container which potentially can cause damage to the goods. While the goods, similarly to the air, also contain moisture and water at various levels depending on the materials they are made of, the same phenomenon is applied to them. This can cause problems when a cargo is transported between different climates.

    The chart clearly illustrates the problem with moisture

    The solution of how to keep your cargo dry and protect it against any damage related to condensation and humidity in a controlled environment is based on an irreversible process:

    The hydroscopic salt in the pole removes the moisture from the air and forms a saline solution that is collected. Once the water has been absorbed by the pole it stays that way. When the temperature rises no water will be re-emitted back to the air. The dew point is never reached and hence prevents the formation of condensation.

    3. Important parameters

    To determine the quantity of poles required in a container to reduce and hold the humidity at a level that will not cause damage the products, the amount of water or relative humidity that needs to be removed must be considered. It depends on the following parameters:

  • Length of voyage,
  • Temperature and humidity during voyage,
  • Type of goods and their sensitivity,
  • Air volume in the container,
  • Container quality,
  • Packaging condition.
  • The number of units needed is in general:

    3 poles (+/- 2) in a 20ft container
    5 poles (+/- 2) in a 40ft container

    If the product in itself contains much water and/or weather conditions at loading is poor, extra pole(s) need to be added.
