Finally less draught and heat loss in the DIY store

/in /by

How to ensure less draught and heat loss with an air curtain system in the entrance area

Operators of DIY and home improvement stores are familiar with this: open entrances to the DIY store or garden centre cause unpleasant draughts due to air mass movements of cold air entering and warm air leaving. This is sometimes favoured by electric sliding doors in continuous operation or open entrances where the doors remain open.

Draughts also form in open roller shutter doors in the delivery area, where the previously expensively heated room air is quickly lost.

With Tekadoor’s air curtain devices, it is possible to retain a large part of the warm air in the room and to screen off the cold air. The result: draughts are difficult to create – a positive effect that benefits visitors, employees and suppliers.

“We are happy when we can contribute to the customer’s business success with our air curtains!”, Shkelqim Axhimusa, Sales & Marketing, Tekadoor.

Air curtains for gates of large DIY stores

Since 1981, Tekadoor has been offering technical solutions to maintain the air or room temperature at a comfortable level in the entrance areas, checkout zones and loading and unloading zones of a DIY store.

The following devices are mainly used here:

  • Secon air curtain as ceiling-mounted solution
  • Colum EC air curtain as a stand-alone solution next to customer entrances
  • TIC – Industrial door air curtain
  • Individual unit solution: customised manufacture and installation of the air curtain

Common areas of application:

  • Gate areas where goods are delivered
  • Entrance areas with automatic sliding doors
  • Entrance area garden centre
  • Access to the DIY store and from the outdoor area into the main building

Success story: DIY and home improvement stores

To sustainably reduce energy costs and to improve the buying experience of DIY store customers, many DIY store operators see Tekadoor products as the ideal solution.

Customers’ requirements for the door air curtain are similar in both design and installation. The device should not only fit in perfectly with the design of the door entrance in terms of colour, but also in terms of the way it is installed.

Tekadoor has already supplied many DIY stores throughout Europe with air curtains. Now the room temperature can be maintained when loading and unloading in the door area. If necessary, the door can also remain open permanently because the air curtain acts like an invisible door. The warm air remains in the building, the cold air is screened off and stays outside.

Customers, suppliers, employees as well as forklift drivers or salespeople can enter or leave the building without costly heat loss.

Tip: Our units are not only intended for the hotel entrance area – they are also suitable for use at other door and gate situations where the air mass exchange described above is to be avoided (examples: Transitions to the neighbouring building, supplier entrance, personnel entrance, loading ramp and goods delivery).

So that your hotel guests feel comfortable

/in /by

Use Tekadoor’s device solution for the hotel, hotel lobby or supplier entrance.

“It’s cold here – there’s a draught” could be the reaction of your potential hotel guests in the entrance area when cold air on the floor enters through the open entrance door.

According to physical laws, heated air rises and the heavier, cold air remains at the bottom.  For entrance areas, this means that when a door is opened, the expensive, warm room air escapes in the upper door area and cold outside air flows into the building in the lower area. This natural thermal effect creates draughts in the entrance area, which hotel guests and staff find extremely unpleasant.

COLUM EC – How it works

Tekadoor offers an energy-efficient solution for this physical process.

The Colum EC and Silencio EC air curtain system can be used to provide a comfortable indoor climate in the entrance area. Due to the even air distribution, the cold outside air is screened off and an annoying ‘cold lake’ on the floor is avoided. In summer, it is also possible to use this series of units with pure recirculated air (without heating). This prevents warm outside air from flowing into the air-conditioned building. Our units can be installed as standing or suspended versions.

Different versions

  • Available as a standing solution or suspended as ceiling mounting
  • Made to measure possible/ RAL colours to match the customer’s corporate ID) / stainless steel version
  • Ideal for entrances with open or automatic doors (sliding doors)
  • Heat exchangers for different heating media
  • EC fans
  • Low operating noise
  • Simple and quick installation
  • Easy maintenance
  • Improves the energy balance

Successful deployment in the hotel sector

Tekadoor is a supplier to the Motel One hotel chain, among others, where the Colum EC and Silencio EC models are preferably used. The customer’s requirements were as follows:

  • Energy-efficient unit for the entrance area with optimum shielding performance
  • Design unit matching the interior
  • Easy operation and control of the unit
  • Made to measure: individual unit lengths depending on the respective door area
  • Low operating noise
  • Delivery and installation by the specialist tradesman
  • Maintenance service by the specialist tradesman

The Colum EC series, which hoteliers can use both in winter and in the hot summer months, turned out to be the perfect solution for the Motel One concept. The hotel management rates the improved indoor climate provided by the Tekadoor Colum EC or Silencio EC units as extremely positive, benefiting especially the hotel guests and staff in the lobby.

Tip: Our units are not only intended for the hotel entrance area – they are also suitable for use at other door and gate situations where the air mass exchange described above is to be avoided (examples: Transitions to the neighbouring building, supplier entrance, personnel entrance, loading ramp and goods delivery).

TEKADOOR’S NEW TOUCH-SCREEN CONTROL WITH INTUITIVE OPERATION

COMBINE DIFFERENT AUTOMATION OPERATIONS TO CONTROL YOUR ENERGY COSTS AND HAVE A SIGNIFICANT POSITIVE IMPACT ON ENERGY EFFICIENCY

For many years, the effectiveness of air curtain systems was measured by their screening performance, but nowadays this performance must also meet energy-related normative requirements that aim to increase energy efficiency. TEKADOOR is therefore continuously developing the components of its air curtain systems. The air curtains have been equipped with ebm-papst fans for years, and their energy-saving effectiveness is complemented by the advanced GTC control system. State-of-the-art technology with a wide range of operating and application options is thus combined in the best possible way with comfort for the user and operator.

IMPROVED GTC CONTROL TECHNOLOGY

TEKADOOR combines the new control options of GTC with a 5″ touch-screen display, which is almost self-explanatory to operate due to its intuitive menu guidance and easy to set for a wide range of applications. A distinction is made between the standard control GTC 1 and the comfort control GTC 2, as well as the GTC E control for door air curtain systems with electric heating coil.
All controls have, among other things, a unique feature: the operator can choose between a 5-step or stepless speed control for all units with EC fans and thus fine-tune them even more precisely!
By touching the respective function surfaces/symbols, individual operating modes can be adjusted to suit the operator. The colour display clearly shows the respective operating modes and symbol displays. The date, time and room temperature are displayed as standard.
The room temperature is recorded as standard via an internal temperature sensor in the control panel.

The GTC 1 control includes a summer/winter circuit, frost protection circuit with optional frost protection, an adjustable maintenance interval (cleaning of the intake grille or filter) and an input for an additional temperature sensor.

With our comfort control GTC 2, 12 different switching times per week can be stored in a timer mode.
It is also possible to operate the door air curtain system via a constant discharge temperature (an additional electronic control valve is required for this).

APPLICATION EXAMPLES

Depending on requirements and on-site conditions, the user can choose between different operating modes:

– Manual – manual operation
– Auto AS – automatic operation via cool-down protection
– Auto RT – automatic operation via room temperature
– Auto TK – automatic operation via door contact
– Auto Kombi – combination option of all individual automatic modes

Likewise, up to 10 door air curtains can be operated in parallel via 1 operating unit in the master / slave principle by different coding of the control boards.
The control board is built into the air curtain unit and a 20m pre-assembled data cable (connection between air curtain and control panel) is included in the scope of delivery.

By combining the various automatic operations as required, the operator can directly ‘control’ his energy costs and have a significant positive influence on energy efficiency.
Integration into existing on-site control systems
As standard, all our controls have a potential-free enabling contact for the on-site BMS / DDC and potential-free operating and fault signalling contacts.
For complete integration into an on-site building management system, our controls can be easily expanded with corresponding modules.
DDC boards and modules for a Modbus connection are available as optional accessories.

ADVANTAGES AT A GLANCE

  •  Made in Germany
  • Touch display
  • 5-step or stepless (stepless only with EC motors)
  • clearly arranged due to colour symbols
  • Summer/winter switching
  • Adjustable maintenance interval
  • Various operating modes

SHAPELY DOOR AIR CURTAIN IN AN APPEALING OVAL DESIGN FOR SCREENING LARGER ENTRANCE AREAS

OVAL EC CONVINCES NOT ONLY ARCHITECTS AND PLANNERS, BUT ALSO BUILDING OWNERS AND OPERATORS.

 

The increasingly popular large entrance portals with sometimes high mounting heights require all the more optimally designed door air curtain systems, which, however, should not impair the spaciousness of the entrance area.

With the Oval EC series, TEKADOOR offers an air curtain that meets the requirements of design, functionality and unobtrusiveness.

IMPROVED TECHNOLOGY

Oval EC is available in variable unit lengths up to 2.5 m and can thus be easily retrofitted and individually adapted to existing door systems. Despite its high air performance, Oval EC is characterised by a low sound pressure level compared to other conventional units. Casing panels and fan housing are sound-absorbing insulated.

For larger entrance widths, it is possible to arrange several units in a row. In this case, the individual units are connected at the top and have only a single central fixing point instead of 4. Only the two left and right outdoor units are fixed with 2 threaded rods each. A concealed power supply with internal cabling and piping can be provided via the optional suspension cladding.

TEKADOOR uses individually driven radial fans with EC motors for this air curtain. The efficiency of the EC motors is approx. 85%, i.e. 20% higher than that of conventional motors, which not only increases efficiency but also significantly reduces operating costs.

Oval EC is supplied with the GTM 2 EC electronic control as standard. The GTM 2 EC control system includes an external operating unit, a control board built into the air curtain unit and a 20 m pre-assembled data cable (connection between the air curtain unit and the operating unit) for easy plug & play installation.

The menu-guided control is in 2 languages (German/English) and has a 2.4″ colour display. Operation or navigation is via a central multifunctional wheel. Depending on the application and requirements, the operator can choose from several operating modes. In automatic mode alone, the GTM 2 EC control has 3 different submenus with timer operation.

The various operating states and fault messages are displayed in plain text and with symbols on the 2.4″ colour display. The date and time are displayed in real time as standard.

POSSIBLE APPLICATIONS FOR MANY DIFFERENT INSTALLATION VARIANTS

The new design air curtain Oval EC is manufactured exclusively for visible operation. The free-hanging Oval EC air curtain is ideal for modern and architecturally sophisticated entrance areas.

Oval EC can be easily strung together to give the visual impression of a single continuous unit in wider entrance and exit areas. The screening function is maintained throughout.

With the optionally available attractive suspension panels for concealing the energy supply, Oval EC not only convinces architects and planners, but also building owners and operators.

SERVICE-FRIENDLY MAINTENANCE

To minimise the maintenance factor, the Oval EC is also equipped with a service-friendly micro-intake grille with filter function. The unit does not have to be opened to clean this ‘filter element’. A simple vacuuming or wiping from the outside is sufficient – without the need for service personnel. And, of course, without follow-up costs due to constant periodic renewal of any filter mats.

ADVANTAGES AT A GLANCE

  • Made in Germany
  • ErP compliant with EC fans
  • Low noise level
  • Robust self-supporting sheet steel housing
  • Individual colour or stainless steel version selectable
  • Individual unit lengths up to 2500 mm
  • Service-friendly due to filterless micro-intake grille
  • Simple assembly or mounting in rows
  • Adjustable air outlet louvre
  • Different PWW heating media possible

SILENCIO EC & SILENCIO COLUM EC

THE EXTRA QUIET DOOR AIR CURTAINS FROM TEKADOOR

WHEREVER LOW NOISE DEVELOPMENT IS REQUIRED.

 

For decades, the trend towards ever smaller, more inconspicuous devices has been decisive in the field of air curtains. At the same time, entrance areas in modern architecture increasingly became entrance portals – mounting heights or air outlet heights of air curtains are sometimes 3.5m and above. This not only leads to an increase in energy consumption, but is also detrimental to comfort. Increasing air outlet heights also require higher unit outputs, which in turn are synonymous with an increase in the noise level of air curtains.

In line with architectural requirements, the units became more and more powerful – and thus more noisy – while their dimensions became smaller and smaller. This trend now had to be counteracted.

IMPROVED TECHNOLOGY

TEKADOOR sets a new, technically up-to-date standard with the development of the “SILENCIO” series. Compared to standard units of the same design, these series are up to 10 dB(A) quieter with the same shielding performance and thus the same air volume. With maximum sound pressure levels of 51 dB(A) (“SILENCIO”) and 52 dB(A) (“COLUM SILENCIO”), these units create pleasant comfort wherever people work in acoustically and climatically sensitive areas. These sound reductions are based on low-speed EC fans, a modified heat exchanger, aerodynamically optimised air outlet blades and various sound-absorbing insulations inside the air curtain.

POSSIBLE APPLICATIONS FOR MANY DIFFERENT INSTALLATION VARIANTS

Door air curtains of the “SILENCIO” series are excellently suited for the retail sector and are offered as freely suspended display units or as cassette units for flush ceiling installation.

The upright design version of the “COLUM SILENCIO” unit group can be found wherever a particularly low noise level is required as well as an elegant appearance that integrates as well as possible into the existing architecture.

These are cylindrical air curtain units in a particularly pleasing column form.  Since the connections of this series are usually “invisible” through the floor or through the footprint of the units, integration is particularly possible in the modern, architecturally particularly sophisticated all-glass portals.

But it is not only the external values that are decisive for air curtain units. For the user, it is not only the appearance and comfort that count, but also the running costs. These are naturally defined by maintenance and consumption costs.

SERVICE-FRIENDLY MAINTENANCE

To minimise the maintenance factor, these series are also equipped with a service-friendly micro-intake grille that takes over the filter function. The unit does not have to be opened to clean this ‘filter element’. A simple vacuuming or wiping from the outside is sufficient – without the need for service personnel. And, of course, without follow-up costs due to constant periodic renewal of any filter mats.

WE OPTIMISE YOUR ENERGY COSTS

To optimise consumption costs, all air curtain units of the “SILENCIO” series are equipped with a programmable electronic 5-step control as standard. Consisting of a control panel with graphic colour display and a control board built into the door air curtain unit. Operation is via a multi-function wheel. The operator can choose from several operating modes depending on the application. For example, automatic operation with door contact control and cool-down protection via room thermostat. The various operating states, fault messages as well as date and time are shown in plain text and with symbols in the display.  This means that the system is also easy to operate for the end user.
Of course, our Silencio air curtain units as well as all other TEKADOOR unit series – not only these particularly sound-insulated series – comply with the current technical specifications and regulations of ErP and are also certified by the German TÜV-Süd.

ADVANTAGES AT A GLANCE

  • Made in Germany
  • ErP 2015 ready / EC fans
  • Particularly quiet
  • Robust self-supporting sheet steel housing
  • Individual colour selectable (RAL 9016 as standard)
