Being in the RAF takes dedication, intensive training and the readiness to handle any situation on land, sea and air. When there is no room for error, you need to be 100% confident in the clothing and equipment you are relying on.

Being in the RAF takes dedication, intensive training and the readiness to handle any situation on land, sea and air. When there is no room for error, you need to be 100% confident in the clothing and equipment you are relying on.

For military and aerospace training facilities like RAF St Mawgan and HMS Raleigh in the UK, the drying of kit between exercises needs to be fast, efficient and reliable.

That’s why both facilities have dehumidifier-powered drying rooms in constant use. Even when the rooms are full, wet equipment ranging from survival suits and protective clothing to dinghies and life-rafts can be dry and ready for action within 24 hours.

Dehumidification is the only solution

Before the drying room was installed, equipment at RAF St Mawgan was left outside to dry and, unsurprisingly, it would rarely be ready in time for the next training session and disrupt scheduling. A common attempt at speeding up the drying process during winter is to turn up the heating, but because warm air is able to contain a higher moisture content, humidity remains in the room and in some materials. If the temperature drops, condensation is likely to form, which will actually slow down the drying process (and result in some expensive energy bills).

RAF St Mawgan worked with Calorex to install three refrigerant dehumidifiers across their drying room facilities. Unlike heating, dehumidifiers re-circulate air throughout the room while physically removing moisture from the air and, in turn, reducing humidity levels. In comparison, Calorex dehumidifiers can reduce energy costs by up to 500% by converting every unit of energy they use into 2.5 times that amount in usable heat.

HMS Rayleigh is also seeing the benefits of drying efficiency in its sea survival training facility, where wetsuits need to be thoroughly dried between sessions. With the drying room temperature set between 25°C-30°C they use a dehumidifier on a 14 hour cycle between 5pm and 7am. Here’s how it works:

How a refrigerant dehumidifier works
  • Damp air is drawn into the dehumidifier and across a refrigerated coil

  • The air is cooled below its dew point, condensing the water vapour

  • Latent heat energy is recovered and re-used

  • Cooled air passes across the condenser and reheated

  • The warm dry air is then returned to the room at the required humidity

Key benefits of Calorex dehumidifiers:

  • High performance level, even in unheated rooms

  • Powerful centrifugal fan

  • Professional hot gas automatic defrost

  • Automatic hygrostat controlled dehumidification

  • Can connect to an external condensation drain or condensate pump

  • Self contained
