UV Lamp Unit

Figure 10

UV Lamp Unit

The UV lamp unit consists of two lamp housings [2] with two UV lamps each [1] that are integral to
the side walls. Both lamp housings are protected by a stainless steel cover [3].
By cross-radiation of the UV units, all surfaces will be disinfected as the shadow zone is reduced.
The operating time of the UV lamps is preset and can be changed by the operator.

NOTE Protection from UV radiation
As a protection from harmful UV radiation, the UV lamps can only be activated
if the front window is completely closed.
