R9409094 External Cooler Kit UDM W22 - Product - Midwich

The external coolers reduce the projector heat dissipation with 70%.This is especially useful when working with devices in hush boxes or when installing multiple projectors in projection towers, which make it harder to remove the heat. The cooler, controlled by the projector, ensures that the ambient temperature of the laser banks, and all other components within the light source are within spec which also improves the laser lifetimes. (You can find more info on this in the product manual.) 

These separate cooling units (complete with cable and tube (8m)) can be placed up to 24m away from the projector itself. You put them in a different room, or even on a different floor, so as not to hinder the on-site set-up and audience. As a result, the fans in the projector don’t need to work as hard to maintain a healthy operating temperature, reducing the noise with up to 6dB as fan speeds drop.
