How humid the air is depends on its Relative Humidity (RH). The Relative Humidity (RH) is a percentage measure of how much moisture the air holds as compared to the maximum amount of moisture air at that temperature can hold. Entirely dry air has RH 0%. Maximally humid air has an RH of 100%, or any excess moisture will rain out.
Even without any condensation, elevated humidity over a period of time is sufficient to cause damage. Many metals will corrode or discolor at a rather modest level of humidity of 60% to 70%. At higher levels of humidity, 80% to 90%, moulds will grow, metal rusts and paint will flak.
TOPDRY desiccant control the dew point temperature
TOPDRY container desiccant helps keep the dew point temperature below the actual temperature, even when the actual temperature drops within the shipping container due to day to night temperature fluctuations. TOPDRY desiccant continues to reduce the relative humidity down to 40%, which decrease the dew point temperature even further
Powerful moisture absorption capacity
At 90%RH, 25C, the absorption capacity of TOPDRY container desiccant is 300% of its own weight. TOPDRY desiccant’s innovative design allows water vapor to easily enter through the flexible package film and into the interior of the bag, where it is transformed into a thick gel and will not leak or escape, has the ability to protect shipment from start to finish through all temperature range and humidity variances.
Easy to use
TOPDRY container desiccant designed with 360 rotatable hook, configured in a continuous strip of 4*250gram desiccant bag, it can hang within the corrugated panels of container wall and only occupy minimal container space.
Completely safe
TOPDRY desiccants are completely safe, non-toxic, can be disposed as regular waste when removed from shipping container or cargo box.
