Chilled Beams

TROX offers a vast variety of chilled beams. There are two kinds of beam types, active and passive. Both systems can be mounted either flush or exposed. In addition, TROX TCB series of beams are recessed into a ceiling void above a perforated ceiling tile.

Passive chilled beams are a simple yet effective cooling device comprising of a cooling coil within a casing. As warm air at ceiling level passes over the coil, which is cooled with chilled water (14ºC), the warm air is cooled as it passes over the coil. The sides of the casing promote a stack effect within the beam. This directs cooled air down into the occupied zone. This air is then replaced by warm air from above the coil in a continuous motion.

Active chilled beams use primary air to create a low pressure inside the casing which draws or induces room air through a heated or cooled coil. The mixed primary and induced air is then discharged via slots into the occupied zone.

Typical selection parameters for TROX TCB Passive Chilled Beams

• Outputs from 125W/m to 350W/m with 1 row coils & 125W/m to 600W/m with 2 row coils

• Outputs of 300W/m give air velocity of 0.25m/s @ 1m below chilled beam

• Suitable for open ceiling aeras & behind perforated ceiling tiles down to 30% free area

• Minimum 3.2mm post painted hole size

• Minimum 300mm ceiling void required

Typical selection parameters for TROX active chilled beams – DID300 / DID600

• Cooling output upto 500W/m

• Heating output normally 50% of cooling

• Typical installation from 1.8 to 3.6m ctrs

• Typical unit height 300mm

• Single beam lengths upto 3.6m

• Side, end & top entry air connections available

• Constant air volume preferred

• 1 or 2 way discharge

Multi-Service Chilled Beams combine cooling and/or heating with a range of other services including:

• Sprinkler Systems

• Lighting

• Public address systems

• Smoke detectors

• PIR sensors

• BMS cables

• Voice & data cables

• CCTV

• Smoke sensors

The performance data of the Multi Service Chilled Beam can be obtained by using the selection for a DID300/600 beam engine.

The TROX High Induction beam engine has been developed to provide a high capacity unit that can provide up to 800 W/linear metre to a space. This top discharge unit minimises the pressure loss for the air path going through the engine and the induction ratio is increased by twice that of a conventional beam engine. This also allows the primary air to be reduced to minimum fresh air levels.
