DID-E2

Active chilled beam with one-way air discharge as a low-noise alternative to fan coil units; choice of two heat exchanger variants for different output ranges.

Active chilled beams for heating and cooling with 2- or 4-pipe heat exchangers for installation in ceiling bulkheads, e.g. in hotel rooms and hospital wards, in the nominal lengths of 1000, 1125 and 1250 mm

Preferably for room heights up to 4.00 m
High heating and cooling capacity with a low conditioned primary air volume flow rate and low sound power level
Media supply on the reverse or from the corridor side
Compact device dimensions oriented to the basic dimensions and 2 different widths or depths for the heat exchanger to cover different output ranges.
Fixing points for various types of suspension systems/points
Combination with different control systems, e.g. X-AIRCONTROL or air-water systems control possible

Optional equipment and accessories

Integrated volume flow controller
Standard grilles from the TROX grille range
Various water connections, smooth CU tube, external thread G1/2" and flat seal, or union nut G1/2" and flat seal
The supply air spigot is extendable (sliding) to compensate for structural tolerances

General information

Application

Active chilled beams of Type DID-E2 for installation into ceiling bulkheads, preferably for room heights up to 4.00 m
Especially for hotel rooms and hospital wards
Load dissipation with water enables a reduction of the primary air flow rate to the required minimum outdoor air flow rate
2-pipe or 4-pipe heat exchangers enable good comfort levels with a low conditioned primary air volume flow rate
Energy-efficient solution, as water is used for heating and cooling

Special characteristics

One-way air discharge
Horizontal heat exchanger as 2-pipe or 4-pipe system
Connections on the rear of the unit, so that the connection is usually made from the corridor side
The supply air spigot is extendable (sliding) to compensate for structural tolerances
Nominal sizes are based on the basic dimensions
Integrated volume flow controller as an option

Nominal sizes

1000, 1125, 1250 mm

5 nozzle variants for optimised induction, as required
Side-mounted brackets for installation with various fixing systems
A mixture of nozzles is possible
Devices without flow rate control unit have a central primary air connection. Devices with a flow rate control unit have a primary air connection on the left or right

Materials and surfaces

Casing, nozzle plate, supply air spigot and installation subframe for secondary air grille made of galvanised sheet steel
Heat exchanger with copper tubes and aluminium fins
Surface of the casing and heat exchanger optionally available in black (RAL 9005)

Standards and guidelines

Products are certified by Eurovent no. 09.12.432 and listed on the Eurovent website
Declaration of hygiene conformity according to VDI 6022
Sound power level of the air-regenerated noise measured according to EN ISO 5135.

Maintenance

Variants without flow rate control unit (VC) are lowmaintenance, as there are no moving parts. The flow rate control unit can be accessed via a separate casing cover for maintenance purposes
The heat exchanger can be vacuumed with an industrial vacuum cleaner, if necessary
VDI 6022, Part 1, applies (Hygiene requirements for ventilation and air-conditioning systems and units)

6 Heat exchanger

Active chilled beams provide centrally conditioned primary air (outdoor air) to the room and use heat exchangers for additional cooling and/or heating. The primary air flows through the nozzles into the mixing chamber, inducing secondary air which flows out of the room, through the induced air grille and the horizontal heat exchanger. Primary and secondary airflows mix and are then supplied to the room horizontally through the supply air grille.

The quick sizing table contains operating points for defined reference units, whereby the data applies for devices without flow rate control units (VC). Further operating points can be calculated using our Easy Product Finder design programme

Installation into ceiling bulkheads
Horizontal primary air connection
Lengths fit basic dimensions 1000, 1125 and 1250 mm
Heat exchanger depths 320 mm and 512 mm
Primary air spigot 123 mm and 158 mm
Installation and connections to be performed by others. Fixing, connecting and sealing material not included
Active chilled beam has 4 suspension points (slotted hole 38 x 8.5 mm) for on-site installation (by others)
Heat exchangers are fitted with water flow and water return connections at the rear, usually towards the corridor
With the optionally available supply air spigot, which works like a sliding spigot, installation areas of 38 – 78 mm are bridged
Secondary air can be drawn in via a ventilation grille from the TROX grille range, the perforated metal plate especially developed for the DID-E2, or through an on-site opening or shadow gap
Secondary air grills must be secured with safety cables. The optionally available installation subframe for secondary air grilles has safety cables that can be mounted on the grille
