Functional description
Active chilled beams provide centrally conditioned primary air (fresh air) to the room and use heat exchangers for additional cooling and/or heating.
The primary air is discharged through nozzles and induces secondary air (room air), which passes through the heat exchanger.
Primary and secondary air mix and are then supplied to the room, passing the motorised damper blades.

Induction units of Type IDH, with one-way or two-way air discharge and high thermal output, providing high thermal comfort levels in the occupied zone.
For freely suspended installation, preferably for very large internal spaces with room heights from 8 to 25 m.
The units consist of a casing with suspension points, a spigot, non-combustible nozzles, and a vertical heat exchanger with condensate drip tray.

Mixed flow
The supply air is discharged from the diffuser into the space with a velocity between 2 and 5 m/s. The resulting air jet mixes with the room air, ventilating the entire space. Mixed flow systems typically provide a uniform temperature distribution and air quality within the space. The originally high velocity of the turbulent air jet decreases rapidly due to the high induction levels of mixed flow systems.
Heat exchanger
The maximum water-side operating pressure for all heat exchangers is 6 bar.
The maximum water flow temperature (heating circuit) for all heat exchangers is 75 °C; if flexible hoses are used, the water flow temperature should not exceed 55 °C. Units for other pressures and temperatures are available on request.
The water flow temperature (cooling circuit) should be at least 16 °C such that it does not permanently fall below the dew point. For units with a condensate drip tray the water flow temperature may be reduced to 15 °C.
Heat exchanger as 2-pipe system
Air-water systems with a 2-pipe heat exchanger may be used for either heating or cooling. In changeover mode it is possible to use all units within a water circuit exclusively for cooling in summer and exclusively for heating in winter.
Heat exchanger as 4-pipe system
Air-water systems with a 4-pipe heat exchanger may be used for both heating and cooling. Depending on the season, i.e. especially in spring and autumn, it may be possible that an office has to be heated in the morning and cooled in the afternoon.
With 267 actuator-driven TROX fire dampers and 49 TROX smoke extract dampers providing ventilation, TROX products represent a great part of the building services.
The dampers are controlled via our TROXNETCOM/AS interface.
A Profibus DP interconnects the 20 controllers on a Simatic PLC with two master interfaces.
Furthermore, the smoke extraction dampers are connected to a fire service alarm panel by means of active AS-i modules with digital inputs and outputs. TROX integrated and commissioned the system.
There are approx. 80 cars on show in the museum. Apart from world-famous dream cars such as the Porsche types 356, 550, 911 or 917, examples of technological excellence from the 20th century by Prof. Ferdinand Porsche are exhibited.
In new design and refurbishment projects TROX is market leader when it comes to fire and smoke protection. This is why experienced maintenance companies know TROX products. TROX gives such companies the knowledge they need in certified training programmes.
Furthermore TROX offers a telephone support line to assist in selecting and installing the right products.
An extensive spare parts service rounds off the services offered by TROX in the area of fire protection. From fusible links and ancillary items to refurbishment dampers, TROX has the widest range of replacement parts available on the market.
