Condensation
Condensation on the surface of the window is caused by the window temperature
falling below the dew point. This may occur in areas of high humidity or large
temperatures differences between day and night. The enclosures are well
sealed but condensation can sometimes occur on the inside of the window.
Condensation can usually be controlled by the following measures:
Fasten a cover or rain hood over the enclosure to shield the •
window from the effect of radiation cooling at night. This also
prevents rain from striking the window.
Use a desiccant pack inside the enclosure. This will only prevent •
condensation on the inside.
Place a heater in the enclosure. The heater can be 12W to 50W •
depending on the size of the enclosure and the conditions of
operation and is controlled by a thermostat to prevent overheating.
The heater raises the temperature of the enclosure and prevents
condensation forming either on the inside or the outside of the
window. To minimise heat loss the enclosure is insulated. This
option requires power to be supplied and there are heaters available
for use in hazardous areas.
