The ROL nozzle duct is designed for rooms requiring large air volumes distributed evenly, silently and without draught. Typical applications include office spaces, workrooms, day care centres, schools, industrial and research premises.

The ROL nozzle duct features optimally sized perforation with a precisely defined perforation pattern. This results in air distribution with extremely good mixing that grabs a large volume of surrounding air. Thanks to the high mixing ratio, ROL is perfectly suited for cooled air.

With the help of ROL-S adjustment and silencer unit is achieved a functional and stylish set which includes both the air flow control and duct noise dampening.

ROL and ROL-S are also supremely easy to maintain and keep clean.

A complete ventilation systemROL and ROL-S form a completed unit for installation and control, which is equipped with a cool slide rail type installation rail. The supply contains connector fittings and an end with a measurement fitting. The smooth surface is very easy to keep clean. The ROL nozzle duct supply air jet drags along a large amount of surrounding air, which means a large air mass is moving at low speed.

The adjustment unit ROL-S, which has very good resilience, can be adjusted accurately. The measurement is based on the pressure difference over the control unit. By using the combination of ROL and ROL-S an accurate, low noise and even air distribution is obtained. ROL-S also effectively suppresses the air sound radiated through the ducts.

In addition to ROL-S adjustment and silencer unit ROL can be fitted with a non-perfora-ted connection or intermediate element of ROL-0.

ROL-S model, quieter than quietROL-S is the best and safest option for applications where high standards are set for adjustabi-lity, noise level and appearance. ROL-S consists of the opened adjustment unit functioning also as a cleaning hatch and of a high quality silencer unit after the adjustment unit. The silencer absorbs the sounds coming from the adjustment and also effectively inhibits the migra-tion of the air sounds coming from the duct work going into the room.

The solution is also visually very stylish, as the type of ROL-S’ duct size and installation rail is always the same as the active element of ROL. ROL and ROL-S are the best combination for schools, offices and day care centers.

New innovative adjustment unit

The new ROL-S adjustment unit provides more accurate and precise adjustment than ever before. Both adjustment and measuring is performed through the patented adjustment unit. The adjustment setting is simply read from the display disc with numbering corresponding to the different k values.

The measurement is based on static pressure difference over the adjustment unit. This gives accurate and reliable measurement even with small pressure differences and low air velocities. The adjustment setting can be locked.

The unit is adjusted using an adjust-ment key or, for example, a screwdriver. The adjustment disc numbers corres-pond to the different k values.

Pressure difference is measured from the connections on the adjust-ment unit.

The adjustment setting can be locked with a screw if desired.

ROL-S also has exceptionally small safety distances of + - 5% measurement accuracy, which leads

to accuracy class 1. Silencer material meets the purity require-ments of M1.

Ease of maintenanceROL and ROL-S are extremely easy to maintain and to keep clean throughout their life cycle. The ROL-S adjustment unit can be easily opened and through the formed cleaning hatch the silencer unit can be cleaned as well as the adjustment unit and the duct from the inside. ROL in turn can be opened from the end and through this the inside can be accessed to perform cleaning work inside the product. The smooth surface is easy to keep clean by vacuuming and wiping with a wet cloth.

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 service

+ ROL-S can be cleaned reliably also from the inside

ROL can be opened also from the end:+ The product can be cleaned

also from the inside

ROL suits your interior perfectlyToday, many rooms and working spaces are carefully designed with a detailed colour scheme. In contrast, ventilation terminal units often are not included in the visual design. ROL now gives you an opportunity to give a finishing touch to the interior. You can use colour to either blend ROL into the surrounding colours or use it as a technological highlight.

The standard colour of ROL and ROL-S is pure white RAL 9016. The basic colours are also black, RAL 9005, white RAL 9010, white aluminum RAL 9006 and steel gray RAL 9007+ 9023. ROL and ROL-S are also avai-lable with a stunning gloss lacquered surface. On request ROL and ROL-S can also be painted in other RAL colours.

In elementicular demanding applications ROL and ROL-S can also be made of stainless or acid-proof steel, as well as of anodized sea aluminum e.g., for indoor swimming pool conditions.

Climecon ROL and the combination of ROL and ROL-S are the best choice for nozzle ducts both for their technical characteristics as well as for the material and color options.

> 10 Pa < 10 Pa

NOTE! Concerns all nozzle ducts.

A sufficient pressure drop creates the coanda effect, guaran-teeing 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.

Draught-free indoor climate and high mixing ratio through sufficient pressure difference

For the best results, ROL nozzle duct comes in four different supply air sector options. This guarantees an optimal throw direc-tion 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 opera-tion. The recommended minimum pressure drop is 10 Pa, providing good control over the throw pattern and reliable adjust-ment for the entire system.

How the nozzle duct ROL works

ROL’s even perforation pattern creates an even, wide air distribution with a good mixing ratio.

NOTE! The supply air area (number of perforations) is standard regardless of sec-tion 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.

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.

Correct pressure drop with all section lengthsROL’s function is based on a carefully designed, even perforation distribution. The supply air area spreads evenly along the entire length of the unit. When the required air volume is known, the optimal length for even air distribution throughout the area is chosen. The widely distri-buted perforation grabs a large volume of surrounding air, resulting in a large air volume moving at a low velocity and free of draught.

ROL nozzle duct, 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-direc-tional 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.

Installation of ROL nozzle duct

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.

The entirely redesigned hanging rail allows quick installation.

The throw pattern, directed away from the module surface, signifi-cantly reduces soiling. The even, smooth surface can be cleaned quickly and easily. The end cap can be opened, allowing easy mechanical sweeping of the inside.

Maintenance and cleaning

Weights

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.
