The surface treatment of TUISKU fulfills the corrosivity category C4 that lasts well in even the most challenging climate conditions.
Larger than 2200×2000 mm units are made of two or more sections joined together.
Individually dimensioned (non-standard) sizes are possible. Please confirm the available size options from Climecon’s technical support.
For surface-mounted snow and rain covers, the duct connection is supplied separately.
Cover dimensions must be min 100 mm larger than opening on all sides.
TUISKU snow and rain covers prevent snow and water from getting into the ducts. TUISKU covers are tested by VTT.
The recommended face velocity is 0.7 m/s.
TUISKU has a slanted bottom with a water drainage hole. TUISKU-PS, TUISKU-V, TUISKU-P and TUISKU-VS are dimensioned at least 100 mm wider and higher than the hole in the wall.
The TUISKU P and V models take in air through the front surface of the grille. TUISKU PS and VS models take in air through the front and sides of the grille. We also recommend water drainage for the air intake chamber, as well as heating.
Speed up installation
Multi-part TUISKU snow and rain covers with vertical vanes are attached from the front using an innovative installation concept, and the installer does not have to go behind the grilles. The renewed, front-attached structure is standard in Climecon’s TUISKU snow and rain covers intended for multi-part installation. The new structure does not affect the performance values of the louvres and their external dimensions remain the same.
