Two-way active chilled beam
$0.00
OptimAir is a water- and air-based induction unit with bidirectional air diffusion, recommended for a wide range of commercial applications—such as office buildings, shopping malls, retail stores, restaurants, and hotels—where a combination of ventilation, cooling, and/or heating is required. OptimAir is designed primarily for false-ceiling installations, but can be supplied with an optional Coanda frame for visible mounting. The unit is available with two plenum alternatives—normal (S) or higher (L) airflow—along with a high-performance heat exchanger to efficiently meet the cooling or heating demands of the conditioned space. For added flexibility, OptimAir can be supplied with adjustable nozzles that allow reconfiguration of the primary airflow even after installation. The nozzles are thoughtfully positioned above the heat exchanger to maximize the coil’s effectiveness and optimally mix the primary supply air with the induced room air. This ensures a well-conditioned indoor environment, enhancing both thermal and acoustic comfort for occupants. For additional efficiency, OptimAir can be equipped with a digital controller developed for DCV (Demand-Controlled Ventilation) requirements.
Function
The function of active chilled beams is based on the well-known induction principle. The primary (dried) air from the air handling unit is injected into the plenum box within the active chilled beam and distributed through specially shaped nozzles. As the air is discharged through these nozzles, the high-velocity air jets above the coil create a low-pressure zone, which draws ambient room air through the coil. As it passes the coil fins, this drawnin air is conditioned (cooled or heated) according to the water temperature in the coil. The conditioned air then mixes with the air jets before being discharged back into the occupied space. The careful placement and shape of the nozzles have a major impact on both the performance of the chilled beam and its sound emissions. It is important that the primary air from the air handling unit is sufficiently dry to maintain a low indoor dew point and prevent condensation. Because water is a more effective medium for heat transfer compared to air, chilled beams are an outstanding energy-efficient solution, reducing the overall energy needed for cooling, heating, and ventilation.
Features
Applications
Chilled beams are a versatile ventilation solutions that provide efficient heating, cooling, and ventilation for various commercial settings. They are particularly effective in environments where maintaining high indoor air quality and energy efficiency is critical. Applications include office buildings, shopping malls, retail stores, restaurants, and hotels.
Applied materials and finish
The visible front panel and outer frame is made of galvanized sheet metal. The fold-down front panel comes with circular
perforation holes, as standard. All visible parts are powder coated in standard white RAL 9003 color with a 30% gloss level. The plenum box is made of galvanized sheet metal, with an EPDM rubber sealing on the air connection spigot. The heat exchanger consists of copper and aluminium. The AirFlex air deflectors are made of Polyamide (PA) plastic.
Slim profile
The OptimAir S and OptimAir L are designed to maximize efficiency in spaces with limited installation height, making them ideal for both new and existing buildings. With an overall build height of just 155 mm (OptimAir S) and 185 mm (OptimAir L), this low-profile design allows for easy integration into ceiling structures, ensuring flexible installation while keeping the setup quick and cost-effective. Despite their compact design, both variants deliver effective cooling, heating, and ventilation performance, contributing to a comfortable and energy-efficient indoor environment.
Adjustable nozzles
Optionally, OptimAir can be supplied with adjustable nozzles—a unique, elegant, and flexible feature for changing the nozzle configuration on each side of the plenum box to achieve the required airflow without altering the primary air pressure. Using a simple Allen wrench, the airflow can be adjusted in seven steps on each side. This makes it possible to set asymmetrical airflows on each side, helping to reduce air velocity and the risk of drafts in the occupied zone, where the colliding air streams meet. Our solution features clever engineering and is designed to stand the test of time. The requested airflow can be selected in our selection software and is factory pre-set, but can easily be changed on-site if needed.
Installation
Opening the front panel
Pull the locking tabs in the direction indicated by the arrows to open the front panel.
Attention! After unlocking the latches, the front panel will immediately open on its own. Be aware of the sudden opening, and make sure to hold the panel to slow its movement, preventing accidents and protecting the product.
The front panel is secured by safety cables, which only allow it to open to a certain point.
Mounting
The suspension brackets on the product are designed for mounting with threaded rods or hook suspension rods. Before installation, these brackets must be rotated, correctly positioned, and then secured with a self-tapping screw, since they are not shipped in the proper orientation for installation.
Comissioning
Attention! The connection of the product’s water and air hose fittings should be carried out by a qualified professional! Threaded solder ends and duct fittings are not included. The unit can be connected to the water and air duct networks with horizontal or vertical connections.
