SOLAR SHIELD TOP
Solar Shield Top provides a vented area on top of the enclosure to
absorb solar heating effects and help keep enclosure cool. Also
provides a drip shield to keep liquids away from the door sealing
surface. Aluminum with RAL 7035 textured light-gray finish inside
and out. Maintains enclosure rating. Includes mounting hardware.
Shielding Effectiveness
Hoffman’s research of the effects of solar radiation on enclosures
has shown the positive benefits of utilizing shielding to decrease
temperature rise. Shielding has been found to be an effective,
low-cost method of reducing solar heat gain in outdoor electrical/
electronic applications.
Test results indicate that a top-mounted solar shield provides a 25
percent reduction in temperature rise due to solar heat load.
