Utilizing a patented two stage filtration system, these outdoor display systems remove dirt and debris first, followed by hydrophobic filters to remove airborne water molecules and microscopic contaminants.

Passive cooling systems are vastly more reliable than active cooling systems using sub-ambient air-conditioning, where thermal shock and rapid rate-of-change thermal conditions cause component stress and premature failure.

DACS enables optimal performance and safe operation within the widest possible temperature range, lowest possible power usage, with minimal noise generation.
