An optimum safety policy with regard to working with substances hazardous to health
starts with the safety of your employees. The relevant legislation is clear: employers
are responsible and must have a policy to avoid the risks that imperil the safety and
health of employees as much as possible. When the source of the emission cannot be
removed, then extraction technology should offer an effective solution for the correct
protection of the person and the work area. Personal Protective Equipment (PPEs)

Installation
F90 fire resistant underbench cabinets
The top module of a VARIO-Flow workstation
up to a width of 1.800 mm is supplied as one
part and is ready for immediate use after
connected on the extraction. The VARIOFlow top module can be placed on an existing
work top. Combinations with an under frame,
an underbench safety cabinet, a work top
and possible taps or other accessories will
be expertly installed by DENIOS mechanics.
The modular construction method means
that it is always easy to change, move or
replace. The workstation of more than 1.800
mm width will be supplied in easy to install
parts. DENIOS takes care of the installation
on site. Our VCA certified mechanics are
highly qualified and bring you a service level
according to the DENIOS Concept.
