KONTIO roof hood

Climecon roof hoods are designed paying special attention to attractive appearance, high degree of separation, solid structure and low pressure loss. KONTIO roof hoods have rectangular form and very low structural height. KONTIO-U model is designed for exhaust air and KONTIO-S for inlet air.

Surface treatment

Corrosivity category C4

Connection type

Flange connection, list connection, Rain cover connection

Material

Galvanized steel, High-grade stainless steel, Painted steel

Description

KONTIO roof hoods for exhaust and inlet air represent Scandinavian design and have been tested in the challenging Nordic climate conditions. Together with OTSO roof hoods they form an elegant entity with an unified style.

The KONTIO roof hoods have a rectangular form. A groove in the middle of the unit strengthens the outer shell. The construction gives them exceptionally solid structure. Structural heights of the KONTIO roof hoods are very low, which also reduces the wind loads and enhances their appearance. A horizontal groove in the middle of the unit provides a visual break on the otherwise uniform structure. This makes the roof hoods look even shallower.

The surface treatment of Climecon’s roof hoods meets the corrosivity class C4 well sustaining the toughest climatic conditions.

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, IT = Coupling connector (for sizes 800×400 and 800×300 only)

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.

KONTIO-U roof hood for exhaust air

KONTIO-U roof hood for exhaust air fulfils the required air velocity despite of its low level of pressure loss.

KONTIO-U also meets the requirement of the exhaust air flow being directed only upwards.

KONTIO-S roof hood for inlet air

 

KONTIO-S roof hood for inlet air is
designed so that the air is taken in
from the sides and the underside
of the roof hood.

 

Flow velocity after the outer shell of the
roof hood is very low. This produces
100 % separation rate and it also
effectively prevents snow entering
the inside of the roof hood.

 

Connections

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.

Connection with roof transition

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 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.
