Beschreibung
ROL ist eine montagebereite lackierte Einheit, die mit einer sauberen, gleitschienenartigen Montageschiene ausgestattet ist. Die Lieferung beinhaltet Anschlussblöcke und ein Endstück mit Messeinheit. Die glatte Fläche lässt sich sehr leicht sauber halten Der Zuluftstrahl des ROL zieht reichlich Umgebungsluft mit sich mit, wodurch sich eine große Luftmasse mit kleiner Geschwindigkeit in Bewegung setzt.
ROL-S ist die beste und sicherste Lösung für Wohnungen, in welchen hohe Anforderungen an die Regulierbarkeit, das Geräuschniveau und das äußere Erscheinungsbild gestellt werden. ROL-S besteht aus einem Regelteil, das sich öffnen lässt und auch als Reinigungsluke fungiert sowie einem hochwertigen Dämpferteil, welches sich hinter dem Regelteil befindet. Das Dämpferteil dämpft die durch die Regelung verursachten Geräusche und verhindert effizient, dass die Luftgeräusche aus dem Kanal in den Raum gelangen.
Eigenschaften:
- Funktioniert in kleinen wie auch in großen Räumen gut.
- Wird gewöhnlich in Büros, Schulen, Forschungs- und Industrieanlagen verwendet.
- Zugfreie gleichmäßige Luftverteilung
- Auch gut für Luft mit Untertemperatur geeignet
- Montagebereite, lackierte Einheit
- Ø 125-500 mm, Längen 1500-6000 mm
- Standardmäßig lackierter Stahl
- Es sind auch RST, HST und mit glänzend lackierter Lack erhältlich.
Als Sonderausstattung sind das Regel- und Dämpferteil ROL-S und der nicht perforierte Anschlusskanal ROL-0 erhältlich.

ROL-S adjustment and damper unit
ROL-S adjustment unit based on the static pressure difference measurement enables highly accurate air flow measurement and control. The adjustment unit allows a precise adjustment of airflow (± 5%) even at low airflows and duct speeds. ROL-S forms an openable clean-out hatch.
ROL-S is easy to adjust
1. The pressure difference is measured from the measuring socket of the control unit.
2. This adjustment can be made by a screwdriver. The adjustment is done by rotating the control dial with the tool. The control dial readings correspond to separate k-values that can be found on the side of the adjustment unit.
3. The adjustment position can be locked with a screw.
The adjustment unit can be opened:
- free access to the duct from the cleaning hatch complying with regulations
- the adjustment unit is easy to clean and maintein
- ROL-S can be cleaned reliably also from the inside

How the nozzle duct ROL works
ROL’s even perforation pattern creates an even, wide air distribution with a good mixing ratio.
For the best results, ROL nozzle duct comes in four different supply air sector options. This guarantees an optimal throw direction in all circumstances.
The airflow in ROL is determined by its diameter. The larger the air volume required, the larger diameter or the more ducts should be chosen. Controlled air velocity and a sufficient terminal resistance or pressure drop are required for perfect operation. The recommended minimum pressure drop is 10 Pa, providing good control over the throw pattern and reliable adjustment for the entire system.
Draught-free indoor climate and high mixing ratio through sufficient pressure difference
A sufficient pressure drop creates the coanda effect, guaranteeing an evenly distributed and well mixed supply airflow. The nozzle duct will then function as designed even with low temperature air.
A low pressure drop will not create the coanda effect, which results in a low mixing ratio. The low-temperature supply air flows down creating a feeling of draught.
NOTE! This concerns all nozzle ducts.
Dimensions
ROL main dimensions + ROL-0 + ROL-S
On request ROL may also be made as a 4 module unit the length of which is 6015 mm in sizes Ø125-400 and 5715 mm in size Ø500.
NOTE! The supply air area (number of perforations) is standard regardless of section length. Thus the pressure drop is not decreased or flow velocity increased as the duct length increases, which improves measurement and adjustment while at the same time ensuring a controlled throw pattern along the entire duct length.

ROL installation examples
The recommended installation distance of the ROL nozzle duct from the ceiling is min 150 mm. Obstacles to the airflow, such as beams or surface-mounted light fixtures, should be avoided.
If beams are located close to one another, it is recommended that ROL is installed next to the beam with a single-directional throw.
The minimum distance between two nozzle ducts should be 3 metres.
Alternative installation when nozzle ducts are less than 3 metres from each other.
Recommended mounting height is 2.5-4.5 meters.
Recommended room height is 6 meters max.
ROL installation
The hanging rail allows quick installation!
The rotating rivets with left-hand thread in the hanging rail move freely, allowing the longitudinal hanging points to be chosen freely.
The rotating rivets make fastening extremely simple and quick, while allowing exact fine-tuning of the height.
Maintenance and cleaning
The smooth surface of ROL is easy to keep clean!
The end cap can be opened, allowing easy mechanical sweeping of the inside. The ROL-S adjustment unit can be easily removed and it operates as a cleaning hatch from which the duct can be swept clean. The adjustment unit can thus be cleaned separately.
