6 Options
6.1 Oil-proof design
RoofVent
®
units in oil-proof design are suitable for use in applications with oil-satu-
rated extract air. The maximum oil load in the extract air is 10 mg/m³ air.
Attention
Danger of damaging the units due to supply air containing oil. Do not
operate the units in 'Recirculation' mode (REC) unless there is no oil pollu-
tion in the room.
Notice
In the 'Air quality' operating mode RoofVent
®
units in oil-proof design
always work in pure ventilation operation (AQ_VE). Recirculation operation
(AQ_REC) and mixed air operation (AQ_ECO) are locked.
6.2 Design for high extract air humidity
RoofVent
®
units in the design for high extract air humidity are suitable for use in
applications in which there is humidification in the room (increase in humidity in
the room by more than 2 g/kg), for example applications in paper and electronics
industries.
Attention
Danger of damaging the units due to ice formation. Do not operate the
units unless icing protection is provided. It is essential to have a humidity
sensor for this.
6.3 Corrosion-protected design
RoofVent
®
units in corrosion-protected design are suitable for use in applications
with an increased corrosion risk, for example applications in the foot industry.
6.4 Corrosion-protected design
for high extract air humidity
RoofVent
®
units in corrosion-protected design for high extract air humidity are
suitable for use in applications with an increased corrosion risk and high increase
in humidity in the room, for example applications in a car wash.
Attention
Danger of damaging the units due to ice formation. Do not operate the
units unless icing protection is provided. It is essential to have a humidity
sensor for this.
