Standard Air Curtain
Secon is the visible, compact door air curtain for optimum shielding of larger doors and gates (shopping centres, shops, DIY stores, supermarkets), which require effective draughtreduction. Installation-ready unit for 3 different installation variants: Free-hanging, flush with the ceiling or for installation in suspended ceilings.
Secon is available in 2 variants. SLW – for smaller to mid-sized entrances with a balanced pressure ratio and ULW – for larger doors and difficult entry situations. In the SLW standard air roll, the recirculating air intake is on the room side and the air discharge directly at the door. In contrast, in the ULW version (reversed air roll), the mixed air intake is by the door and the air discharge on the room side.
The air exits via the Coanvara discharge system, a multi-nozzle system with optimised, drop-shaped profiles. Using the Coanda effect to bring the individual streams together results in a very broad, homogenous air stream. The purposely long profiles, which are parallel and steplessly adjustable in both directions (up to 40°), act as a flow straightener. This ensures the stream mixing factor remains low, as desired.
The selected discharge temperature is carried far down to the floor, effectively preventing the room from cooling down. This means the discharged air is heated less than it would have been if a conventional air curtain had been used.
Self-supporting, powder coated sheet steel housing. Screws are not visible. Available in RAL 9010 as standard (pure white). Other colours are available. Intake grille with micro grille behind it as an intake filter, for service-friendly use. Can be removed without tools for easy cleaning. Inspection panel hinged on one side, opened with casement fasteners. The Coanvara discharge system is flush with the underside of the unit.
Water and electrical connections can be made either from above (right-left) or from the side.
Heat exchangers for different heating media
LPHW: For normal temperature LPHW 70/50 °C and lowtemperature LPHW 60/40 °C, other temperatures available on request. High-quality heat exchanger made from copper tubes, with pressed-on, extra-strong aluminium fins.
Easy to clean (micro grille) without opening the unit by simply vacuuming the intake grille.
Inspection panel closed and secured with a casement fastener (hinges on one side) on the lower side of the unit – easy to open.
Equipped with individually-driven, efficient, ErP-compliant AC radial fans from ebm-papst as standard. These can intake air in both directions, are maintenance free, have vibration-free bearings and come with integrated thermal contacts for motor protection.
Can also be supplied with EC fans on request. The fans are located on a motor plate, which (after opening the inspection panel) can be pulled out downwards.
Easy installation thanks to grooved tracks with sliding blocks (M10) set into the top of the unit. This simplifies adjustment of the unit's position during installation. 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. (Plug&Play)
Electronic TEKADOOR GTC AC control unit, multifunctional with touch display, including an optional ModBus interface
A GTC 1 AC 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 AC 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 fan operation is offered as standard. A maximum of 10 units can be connected in parallel.
