DID312

Active chilled beam with two-way air discharge, 300 mm nominal width, vertical heat exchanger and condensate drip tray

Active chilled beam for heating and cooling, with 2-pipe or 4-pipe heat exchanger, for integration with various ceiling systems. The condensate drip tray is useful if the temperature temporarily falls below the dew point.

  • 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
  • High comfort levels due to low airflow velocity in the occupied zone
  • Three nozzle variants to optimise induction based on demand
  • Hinged, removable induced air grille in four designs


Optional equipment and accessories

  • Control system
  • Additional casing for extract air
  • Heat exchanger powder-coated black
  • Powder coating in many different colours, e.g. RAL CLASSIC

    Application

    Application

    • Active chilled beams of Type DID312 for the integration into various ceiling systems, preferably for room heights up to 4.00 m
    • The vertical heat exchangers and the condensate drip tray are useful if the temperature temporarily falls below the dew point.
    • 2-pipe or 4-pipe heat exchangers enable good comfort levels with a low conditioned primary air volume flow rate
    • Energy-efficient solution since water is used for heating and cooling

    Special characteristics

    • The vertical heat exchanger with condensate drip tray is useful if the temperature temporarily falls below the dew point
    • Hinged, removable induced air grille in four designs
    • Heat exchanger as 2-pipe or 4-pipe system
    • Internal nozzle plate with punched nozzles (non-combustible)
    • Water connection at the narrow side, Ø12 mm Cu pipe, either with plain tails or with G½" external thread and flat seal

    Nominal sizes

    • 900, 1200, 1500, 1800, 2100, 2400, 2700, 3000 mm

    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 into the mixing chambers; as a result of this, secondary air (room air) is induced via the induced air grille and passes through the heat exchanger.

    Primary and secondary air mix and are then supplied to the room horizontally through the supply air slots.

    Active chilled beams of Type DID312, with two-way air discharge and high thermal output, providing high thermal comfort levels.

    For installation flush with the ceiling, preferably in rooms with a height up to 4.00 m.

    The units consist of a casing with suspension points, a spigot, non-combustible nozzles, and two vertical heat exchangers.

    Three nozzle variants to optimise induction based on demand.

    Special characteristics

    • The vertical heat exchanger with condensate drip tray is useful if the temperature temporarily falls below the dew point
    • Hinged, removable induced air grille in four designs
    • Heat exchanger as 2-pipe or 4-pipe system
    • Internal nozzle plate with punched nozzles (non-combustible)
    • Water connection at the narrow side, Ø12 mm Cu pipe, either with plain tails or with G½" external thread and flat seal

    Materials and surfaces

    • Casing, front frame, nozzle plate, and perforated induced air grille (LR/LQ) made of galvanised sheet steel
    • Border and blades of the induced air grille (GL/GQ) made of aluminium sections
    • Heat exchanger with copper tubes and aluminium fins
    • Exposed surfaces are powder-coated pure white (RAL 9010) or in any other RAL colour
    • Heat exchanger also in black (RAL 9005)
    • Nozzle plate powder-coated black (RAL 9005)
    • Additional casing for extract air with a spigot made of galvanised sheet steel

    Construction

    • Powder-coated RAL 9010, pure white, gloss level 50 %
    • P1: Powder-coated in any other RAL colour, gloss level 70 %
    • P1: Powder-coated RAL 9006, white aluminium, gloss level 30 %

    Technical data

    • Nominal length: 900, 1200, 1500, 1800, 2100, 2400, 2700, 3000 mm
    • Length: 893 – 3000 mm
    • Height: 210/241 mm
    • Width: 293, 300, 312 mm
    • Primary air spigot, diameter: 123/158 mm
    • Primary air volume flow rate: 5 – 70 l/s or 18 – 252 m³/h
    • Cooling capacity: up to 1830 W
    • Heating capacity: up to 1240 W
    • Max. operating pressure: 6 bar
    • Max. operating temperature: 75 °C

    Installation and commissioning

    • Preferably for rooms with a clear height up to 4.00 m
    • Flush ceiling installation
    • Side entry primary air spigot
    • Lengths from 893 to 3000 mm, and widths of 293, 300, and 312 mm, hence suitable for various ceiling systems
    • Installation and connections to be performed by others; fixing, connection and sealing material to be provided by others
    • Active chilled beam has 4 suspension points (6 for nominal size 2100 mm and above) for on-site installation (by others)
    • Heat exchangers are fitted with water flow and water return connections at the narrow side


    Installation into T-bar ceilings

    • To avoid too much load on the ceiling, the suspension points should be used

    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.
