Die OTSO Abluft- und Frischluftverdecke sind für skandinavische Architektur und nordische Bedingungen ausgelegt. Gemeinsam mit den KONTIO-Verdecken bilden sie ein stilvolles einheitliches Gesamtbild. Die Verbindung im OTSO ist rund.

Die OTSO-Verdecke sind rechteckig. In der Mitte des Verdecks verläuft eine Nut, welche den Außenmantel abstützt. Die Konstruktion ist außerordentlich stabil. Die Konstruktionshöhen sind in den OTSO-Verdecken sehr gering, was wiederum Windbelastungen senkt und das äußere Erscheinungsbild verbessert. Die in der Mitte der Verdecke waagerecht verlaufende Nut lässt die Konstruktion des Verdecks noch einheitlicher erscheinen. Hierdurch sehen die Verdecke niedriger aus als ihre Vorgängermodelle.

1 = Climecon roof hood type

2 = Direction of the air flow: U = Roof hood for exhaust air, S = Roof hood for inlet air

3 = Connector size

4 = Material: ZN = Galvanized steel, HST = High-grade stainless steel plate, Ma = Painted steel

5 = Connection type: S = Rain cover connection, L = Flange, T = Male connector

6 = Painting: Note! When ordering a paint job, the desired colour and paint film thickness shall be indicated in the order.

7 = Roof transition: KL30 = Fire class EI30, KL60 = Fire class EI60, KL120 = Fire class EI120
Note! The upper connection on the roof transition always matches the size and the model of the connection of the roof hood. The connection on the lower end shall be chosen separately.

8 = Lower end connection of the roof transition: L = Flange, S = Male connector, IT = Coupling connector

Note! In order to define a roof hood model the data for the five first points is needed.

Dimensions for standard rain covers

The standard rain covers are designed to be compatible with Climecon roof transitions. In addition to the outer dimensions of the roof transition there is a space of 25 mm reserved on each side for the structure protecting the roof transition. Rain covers for other sizes can be made from order.

Rain cover joint connection method:

The rain cover is made at the factory to measures to fit the outlet. The benefit of this connection method is safe insulation against moisture damage, since all the connection seams between the roof hood and the rain cover are factory-made.

1. Rain cover 2. A roof transition connection according to the connection method of the roof hood

Flange connection method:

Both the flange on the roof hood and the counter flange are included in the delivery.

1. Flange 2. A roof transition connection according to the connection method of the roof hood

Male connection method:

The male connection can be used only if the size of the roof hood connection Ø is less than 500 mm.

1. Male connector 2. A roof transition connection according to the connection method of the roof hood

Climecon roof transition is made on the factory, sheltered from the weather and always designed just for the particular connection method. The roof transition is available for all three OTSO connections. The fire class of the transition can be selected from EI30, EI60, or EI120. We use PAROC Hvac Fire Slab for fire insulation material. Insulation thickness is always 60 mm in all fire ratings.

The roof transition is attached to a load-bearing roof structure with the L lists (80x80x15) included in the delivery. The roof transition is made from galvanized steel. The upper connection on the roof transition always matches the roof hood. The lower connection method may be chosen according to the product selection menu.
