Dirty air filter found behind a failed outdoor LCD

BoldVu® Has No Air Filters

Stop Changing Out Dirty Filters

Our patented open-loop / closed-loop design manages heat without the use of filters and protects vital electronics from the worst enemies: dust and moisture. Cool air in – hot air and debris out.

Spectrum-Center-3

IP66-sealed components stay clean, dry, and cool.

BoldVu® exclusively uses centrifugal fans for minimal noise and power consumption.

Service calls are not needed to replace air filters.

Optimal low power consumption means lower costs.

… But How?

Our CoolVu® system doesn’t use air conditioners or air filters and we never expose electronics, display surfaces, optical films, or backlight assemblies to ambient air. CoolVu® is a heat exchanging system that cools electronics with an IP66 sealed volume of (closed-loop) air that continuously circulates across the surface of the LCD and over the electronic components. Then a separate volume of ambient (open-loop) air passes through isolated channels in the heat exchanger(s) and exhausts the heat out of the display chassis. All electronics are kept cool, dry, and clean for life.
