Chimneys Fans for Livestock House Climate
DACS A/S has developed a new roof fan chimney. The system reduces transport costs by 80 % and offers significant savings on installation costs. Carries its own weight: The assembled unit is so strong it will carry its own weight to lengths in excess of 10 meters (35 ft.), and it installs without additional supports, simply by screwing it straight into the roof construction.
The production technique gives a panel with a surface boasting superior hardness and chemical resistance, and an inner porous core with thermal insulation properties equal to or better than expanded polyurethane.
High thermal properties
The result is a chimney with excellent thermal properties, suitable for use in ambient temperatures ranging from -40˚C to +60˚C (-40˚F to +140˚F). The heat conductivity of the material is k = 0,06-0,07 W/m 8K (equivalent to cork). In comparison, mineral wool has a heat conductivity of 0,045 W/m 8K.
