Silencio EC & Silencio Colum EC

THE LOW NOISE DOOR AIR CURTAIN

INDIVIDUAL
INNOVATIVE
ENERGY-SAVING



  • Applications

    Silencio EC and Silencio Colum EC are used in acoustically
    sensitive entry areas, e.g. close to where people are working.
    Installation-ready ventilation units which can be used for many
    applications and installation variants.
    Silencio EC - Free-hanging or as cassette unit with intake on the
    underside for installation flush with the ceiling.
    Silencio Colum EC - vertical design variant. The Silencio Colum
    EC will impress you with its low noise operation and curved design.
    The choice of standard RAL powder coatings or a stainless steel
    housing fit superbly in existing entry areas.

  • Special design

    Silencio EC and Silencio Colum EC are characterised by a lower
    noise level when compared with other standard units. The sheet
    metal housing and the fan casing have been acoustically insulated.
    Low-speed fans and adapted heat exchangers contribute to a
    further reduction in the noise level.

  • The housing

    Silencio EC - Self-supporting steel housing. Screws are not visible.
    High-quality powder coating, RAL 9016 as standard (traffic white).
    Other colours are available. Access panel hidden behind the intake
    grille. Aerodynamically-optimised aluminium discharge fin, flush with
    the underside of the unit and adjustable in 5 stages. Perforated metal
    intake grille with micro grille behind it as an intake filter.
    Silencio Colum EC - Self-supporting steel-composite construction
    in a cylindrical shape with split sheet steel or stainless steel housing
    (polished to grain size 240) in a round-rolled design. Screws and
    rivets are not visible. Powder coated intake grille in the same colours
    as the unit or stainless steel version, consisting of a perforated
    plate with micro grille behind it for easy maintenance application.
    Aluminium discharge fins for an infinitely adjustable, unidirectional

  • Heating media LPHW

    Heat exchangers for different temperatures: for normal temperature
    LPHW 70/50°C and low-temperature LPHW 60/40°C,
    other temperatures available on request.

  • Maintenance

    Easy to clean (micro grille) without opening the unit by simply
    vacuuming the intake grille.
    Silencio EC - Discreet secured inspection panel hidden on the
    lower side of the unit (hinges on one side) – easy to open.
    Silencio Colum EC - The intake grille must be removed before
    the revision panel can be opened. To do this, a cross-headed
    screw at the upper end of the intake grille must be removed.
    Then the intake grille can be taken out of the lower frame.

  • EC fans

    The efficiency of the EC fans used by TEKADOOR is > 90% under
    partial load operation. This is approx. 30–35% higher than for
    conventional AC fans. This does not just increase the efficiency,
    but also reduces the operating costs. The individually-driven
    EC fans with integrated motor protection can intake air in both
    directions. They have vibration-free bearings and are controlled by
    a PWM signal (pulse width modulation). They do not just comply
    with Directive ErP, but actually exceed this standard.

  • Mounting

    Silencio EC - Simple mounting thanks to the rivet nuts (M8)
    incorporated on the upper side of the unit and optionally-available
    assembly materials. In the standard version, the unit does not need
    to be opened for electrical connection. Connection terminals for the
    voltage supply, as well as the connectors for the control unit and
    parallel operation can be accessed from the outside.
    Silencio Colum EC - Floor mounted vertical unit: Problem-free
    mounting via holes in the floor plate directly on the finished flooring.
    The floor plate has appropriate holes for invisible energy supply
    from below.
    Optional: Power supply is also possible from above.

  • Control

    Electronic TEKADOOR GTC EC control unit, multifunctional with touch display, including an optional ModBus interface
    A GTC 1 EC control unit is used as standard for models with LPHW heating. The units come with 20 m preassembled and shielded data cable. The GTC 1 EC 5-stage control unit includes the ability to switch from manual to automatic and from summer mode to winter mode as standard. A solenoid valve of up to 2.5 A can be connected as an option for the winter mode. The control unit includes a manual to automatic mode switch and a potential-free contact for enabling via any on-site BMS or BEMS. A choice of 5-stage or stepless fan operation is offered as standard. A maximum of 10 units can be connected in parallel.

Details



Anschlüsse

Connections Silencio EC

Heating connections – DN 32 flow and return – on top of the
unit as standard (Silencio EC) or at the side (Silencio Cassette
EC) for easy connection to the on-site heating system.
Optionally, the connections can also be located at the side.





Anschlüsse

Connections Silencio Colum EC

Floor mounted vertical unit.

Heating connections – flow and return – for easy connection to
the on-site heating system.
Connections: For the floor mounted vertical unit - either from

Ausblaslamelle

Discharge fin Silencio EC

The shielding performance of the door air curtain unit is optimised
by adjusting the discharge fin. The fin can be adjusted in 5
stages. During the heating period, the discharge fin should be
tilted outwards by 10 to 15 degrees to prevent cold air coming
in from the outside. In contrast, during operation in the summer,
the fins are tilted inwards, so that the cooled indoor air cannot
escape.





Ausblaslamelle

Discharge fins Silencio Colum EC

Aluminium discharge fins (drop profile), depending on the model
available in designs with double or multiple fins, for an infinitely
adjustable, unidirectional air stream. During the heating period,
the fins should be tilted outwards by 10 to 15 degrees to
prevent cold air coming in from the outside. In contrast, during
operation in the summer, the fins are tilted inwards, so that the
cooled indoor air cannot escape.
