Historically, Tempest has avoided the use of active cooling, and successfully maintained acceptable operating temperatures using high-velocity forced air cooling even in the hottest climates. Now, with the advent of laser light sources, there is a need to maintain a more constant temperature at levels that may be below the outside ambient level. Tempest now offers two active cooling options - AC Assist and ActiveCool. AC Assist - for Cyclone and Blizzard outdoor enclosures. An outdoor-rated spot cooler that blends cooled air with ambient air to reduce inlet air temperature by as much as 12C.
ActiveCool - for larger Cyclone enclosures. A sealed AC solution that maintains a constant optimum operating temperature inside the enclosure, regardless of the outside ambient.
Since outdoor video-mapping applications often have to deal with very long throws, building an AC compressor into the enclosure itself can cause vibration, and image wobble - a big no-no... Tempest active cooling solutions place the active cooling components in an external enclosure, connected with flexible hoses, with optional anti-vibration mounts to guarantee a steady, vibration-free image.
