LHW units can be adapted to the requirements of the specific project with a series of options.
You will find a detailed description of all optional components in Section K 'Options' of this handbook.
Option Use
ColdClimate design For installation of the RoofVent
®
unit in areas where the fresh
air temperatures fall below –30 °C
Explosion-proof design For installation of the RoofVent
®
unit in explosive areas (Zone
1 and Zone 2)
Oil-proof design
When using the RoofVent
®
unit in applications with high oil
content in the extract air
