Silencio EC

THE LOW NOISE DOOR AIR CURTAIN

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.

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.

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.

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.

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.

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.

Connections

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.

Data cable connection / interface

Simple, standard plug and play connection of the data cable
and an optional solenoid valve on the top of the unit.
The connection can be offset on request.
Control:
Input for the data cable to the control unit.
Auxiliary:
Output for parallel operation with other units.

_0002_tekadoor-luftschleier-silencio-ec-anschlussbox

Connection box

Simple electrical connection via connection box (voltage supply 230 V/50Hz) on the top of the unit (Silencio EC) or at the side (Silencio Cassette EC); connection can optionally also be offset.

Discharge fin

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.

Silencio EC

OPTIONAL ACCESSORIES

Thermostatic straightway valve

Setting range + 20 °C to + 35 °C) limits the discharge temperature (constant supply air temperature limitation). Also available as a 3-way valve.

Door contact solenoid switch

In automatic mode switches on the door air curtain in the preselected stage.

Ceiling attachment set

For problem-free, vibration-free ceiling attachment, consisting of M8 or M10 threaded rods, up to 1000 mm length, vibration dampers, turnbuckles and counter nuts.

Frost protection thermostat

For monitoring LPHW heat exchangers exposed to the risk of frost. As soon as the temperature falls below +7 °C, the fans are switched off and an optional solenoid valve is opened.

Silencio EC

OPTIONAL ACCESSORIES

Solenoid valve

Opens or closes the warm water circuit in the summer/winter setting of the control unit, in order to close the heating water circuit and save energy during summer operation or when the air curtain is not working (normally closed).
Caution: If solenoid valves are used, it is expressly recommended to install a frost protection thermostat (automatically actuated) and a strainer.

Thermo-electric shut-off valve

230 V / 50 Hz, normally closed. On-site installation in the heating flow. Actuated by the summer/winter circuit. Summer function – closed. Winter function – opened.

Electronic control valve

Electronic valve with 0-10V impulse and blow-out temperature sensor completely installed and wired. In combination with the GTC 2 control, a preselected blow-out temperature is kept constant.

Silencio Colum EC

THE LOW NOISE DOOR AIR CURTAIN

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 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 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.

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 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.

Maintenance

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.
