the cabinet allows maintenance work to be
carried our swiftly without special tooling.
The “service mode program” enables simple
changes and diagnostic checks to be made
with ease.

In case of a temperature alarm the UV

lamps are switched off automatically and a
relay contact is activated. The housing of
the cabinet is steel coated and splash proof
