Your Air Curtain FAQs Answered
Our WING Air Curtains attract a lot of attention due to their sleek design, cost efficiencies and variety of sizes and options (ambient, water, electric).
Aside from these clear features and benefits, we also receive a range of other questions for more specific details. We have collated some of these queries below, to cover off what you want to know about air curtains, but have been too afraid to ask… |
HOW DO I CHOOSE THE RIGHT AIR CURTAIN?
The width of the air outlet from the air curtain should be wider than or equal to the width of the door opening. In order to ensure effective protection, set the fan speed to such a level that regardless of the mounting height, the air speed near the floor is not less than 2 m/s.
CAN ALL WING AIR CURTAINS BE MOUNTED IN A HORIZONTAL AND VERTICAL POSITION?
All devices, regardless of the length, are designed to be installed horizontally (WING W/E/C) and vertically (WING W/C). Air curtains with electrical heaters (WING E100-E200) are not suitable for vertical mounting. In the case of vertical installation, it is possible to mount the motor pointing upwards or downwards. The mounting method does not affect system stability in any way.
HOW DO I ADJUST THE ROTATIONAL SPEED OF THE WING CURTAIN DEPENDING ON THE EXPECTED MOUNTING HEIGHT?
Each model of WING air curtains has three stages of fan speed forced by the controller.
WHAT ARE AMBIENT CURTAINS?
WING ambient curtains are air curtains without any function of air heating. These curtains are not equipped with a water or electric heater. From the user’s point of view this means that the temperature of the air stream at the curtain’s outlet is equal to the temperature of the air drawn from the environment.
WHAT TEMPERATURE OF THE AIR AT THE INLET SHOULD BE TAKEN INTO ACCOUNT FOR CALCULATING THE HEATING POWER?
The air temperature prevailing in the room or the temperature to be set and maintained by other heating systems.
DOES THE CONTROLLER HAVE THE POSSIBILITY OF ADJUSTING THE LEVEL OF THE CURTAIN’S HEATING POWER?
Yes. The controller WING EC allows adjustment of heating power of the WING E.
For WING W equipped with a valve, it is possible to enable or disable the function of heating. Without a valve, the heat exchanger remains in the free flow of the heating agent.
WHY IT IS NOT RECOMMENDED TO CONNECT THE DOOR SWITCH ALONG WITH THE VALVE AND ACTUATOR IN THE WING W CURTAIN?
When connecting a door sensor it is not recommended to use a valve with an actuator due to increased inertia of the system i.e. the heating time of the heat exchanger and the time it takes for the actuator to open the valve.
CAN THE AIR CURTAINS BE MOUNTED IN GROUPS?
Yes, it is possible to mount the curtains in groups, which enables the security of the door opening of any length (eg. 3 m, 3.5 m, 4 m, etc.).
Ask us more about some of the projects we have completed with grouped WING air curtains.
CAN THE DOOR SENSOR OFFERED BE CONNECTED TO ANY TYPE OF AIR CURTAIN?
Yes, the reed switch offered by VTS is able to serve air curtains with EC motors. There is a possibility to connect one reed switch to one controller WING EC. The controller can be connected with up to eight WING EC air curtains.
CAN MY WING AIR CURTAIN OPERATE WITH A NON-FREEZE MEDIUM?
Yes, you can. The most frequently used non-freeze medium is a water solution of ethylene glycol. The heaters mounted in a WING can support up to 50% mixtures. Make sure to check however, if other elements of the technological heat installation (valves, pump, etc.) are adapted to work on glycol mix. To do this, check the recommendations of the manufacturers of particular components used. Remember that the use of glycol mixes, which are usually characterised by higher viscosity and lower thermal capacity, compared to water, increases the resistance of heating medium flow and reduces the heating power of the device.
