Stratification supply air diffuser
SUPPLY AIR DIFFUSERS FROM SWEDEN
Stratification diffuser for wall-adjacent air distribution
Repus stratification supply air diffusers are based on circular nozzle ducts that are mounted so that the air is blown towards an adjacent wall. The airflow follows the wall surface down towards the occupied zone, creating a controlled, stratification air distribution with good comfort.
The solution is particularly suitable along glass facades, where the airflow counteracts cold drafts and reduces the risk of condensation on the glass surface. For stratification installations, the DKL and DKS models are available for high airflow rates, as well as DKL-SP for semi-integrated installation in suspended ceilings.
Controlled air distribution
Wall-adjacent air supply directs the supply air down towards the occupied zone and creates a stable stratification function.
Suitable for glass facades
The airflow along the facade counteracts cold drafts and helps reduce the risk of condensation on glass surfaces.
Flexible mounting options
Choose between freely mounted nozzle ducts, models for high airflow rates, and semi-integrated solutions with low installation height.
Our models for stratification supply air
DKL
Circular nozzle duct
Repus nozzle ducts DKL can be mounted free-hanging in the room with mixing air distribution to both sides.
DKS
Circular nozzle duct - high airflow rates
Repus DKS nozzle ducts can be mounted freely suspended in the room or along a wall. Mixing or stratification ventilation can be selected depending on placement.
DKL-SP
Semi-integrated nozzle duct
QUESTIONS & ANSWERS
Frequently asked questions about stratification supply air diffusers
Here you will find detailed answers to the questions we most often receive from consultants, contractors, and technical specialists.
The supply air is directed towards an adjacent wall and follows the surface down towards the occupied zone. There, the air is distributed at a low velocity, creating a temperature and air quality stratification in the room.
The solution is suitable for premises with high ceiling heights, high heat loads, or glass facades where air needs to be supplied in a controlled manner close to the occupied zone. It can be used in halls, atriums, public spaces, and buildings with large glass sections, among others.
A stratification diffuser supplies air along a wall or facade surface, where the airflow is guided down towards the occupied zone, creating a controlled stratification in the room. A displacement diffuser, on the other hand, supplies air at a low velocity directly at a low level, after which the air spreads across the floor and rises when heated by people and equipment.
The airflow is directed along the glass surface and helps maintain a more even surface temperature. This can reduce the risk of condensation and at the same time counteract cold drafts, provided that the system is dimensioned according to the glass surface temperature and the room's moisture load.
Repus offers DKL and DKS nozzle ducts for visible mounting, and DKL-SP for semi-integrated mounting in suspended ceilings. DKS is particularly suitable for installations with high airflow rates.
Mounting height, distance to wall, throw length, nozzle direction, size of glass surfaces, temperature conditions, and design airflow rates affect the function. Repus can assist with product selection, dimensioning, and adaptation based on drawings or project documentation.
