Classic Car / Car Storage Humidity Control

 

The condition of a vehicle stored in either a domestic or commercial environment can be directly affected if the storage conditions are not ideal. To prevent corrosion of steels, a relative humidity (RH) of 50% is required and this level of humidity can be completely independent of temperature.

It is important to provide control around this point, as higher than 70% or so can lead to mould growth, and below 40% can increase the risk of drying out leather and wooden trims and veneers.

Methods of controlling RH at these levels can be achieved by 3 methods, as follows:

Heating. Simply raising the temperature of the air will reduce the RH in the air but will not alter the moisture content or dewpoint. In this manner, RH can be adjusted, but in the summer months, such an ‘adjustment’ may require heating of a building to temperatures approaching 350C. You will also run the risk of condensation forming if the building or garage is not adequately insulated.

Cooling Dehumidification. The more ‘domestic’ approach to dehumidification relies on the ability of a cold surface to condense moisture and control RH by the removal of this moisture. This works if the temperature is at a ‘comfort’ level as would be seen in a domestic environment, but leads to potentially costly running costs for additional ‘background’ heating in a commercial venture.

Desiccant (chemical) dehumidification. This method uses the absorption capability of a desiccant to take moisture out of the air AT ANY TEMPERATURE and as such operates at the most economic level for commercial ventures, and indeed for domestic garages, where there is no requirement for temperature control.

Dehum is currently protecting many £millions worth of classic cars in both commercial car stores and for private collections, even for valuable vehicles stored in ‘rising drive’ garages at client’s private dwellings. These particular garages present their own challenges, which Dehum is pleased to be able to meet.

The Dehum units we supply operate at the most efficient level and will control the RH around your collection reliably and with accurate control. For a commercial venture, this control represents an important additional benefit to potential clients, as you can advise that your premises will protect their property effectively at all times of the year and away from the influence of outside conditions.
