An air curtain effectively keeps the cold out and retains warm air—but only if it operates correctly. The new Halton Windis air curtain is easy to install, maintain, and use. Furthermore, it helps minimize energy loss at the door opening, reducing costs and the building’s carbon emissions.
What can be the largest energy consumer in commercial, public, and industrial buildings located in cold climates? Few people realize it is often the doorways of exterior doors. When the doors open frequently, costly heated indoor air escapes.
An air curtain device creates a strong barrier of air at the entrance whenever the door opens, minimizing the loss of warm air. At least in theory.
“It’s no secret that air curtain devices don’t always function perfectly. A common malfunction scenario is when a sliding door opens, the device activates too late or not at all,” says Mikko Toivonen, Halton Buildings sales agent in Finland.
Another possibility is that the air curtain device blows large amounts of hot air when it is not needed. When the device operates at tens of kilowatts, this wastes a significant amount of energy.
“This can continue for years, and the property owner may remain unaware of whether the device is functioning properly,” says Toivonen.
The Halton Windis air curtain device is designed to tackle common issues. Users can precisely program all essential parameters, including timing, blowing intensity at different temperatures, and their responses to opening and closing doors. When all functions are tailored for the application, the device performs optimally.
“The air curtain can be easily connected to the building management system (BMS), and the user can monitor its operation from a mobile device. What is essential is that the device always operates according to real needs – no more, no less,” says Toivonen.
Halton Windis is the only air curtain device available with an integrated energy meter. This meter utilizes ultrasonic technology and provides real-time reports of energy consumption. Consequently, it helps reduce consumption and the building’s carbon footprint, supporting the property owner’s climate objectives.
Replace parts, not the entire device
All air curtains have wearable components, such as fans and heaters. Replacing these parts is often so difficult and expensive that purchasing a new device becomes more economical. This results in waste of materials, energy, and natural resources.
Halton Windis is designed for the easy and quick replacement of worn parts. Spare parts are affordably priced and widely available.
“You simply need to open the front panel. For example, you can replace the fan in just a few minutes. The initial installation of the device has also been simplified. Unlike in some traditional models, controls, sensors, valves, and all other components are housed within the unit, so the installer does not need to open any hatches,” Toivonen explains.
Benefits for all
Halton Building’s Head of Project Sales, Janne Summanen, is pleased with the new product, which addresses the concerns of many stakeholders.
“Contractors value easy installation and maintenance. Property owners value energy savings and a reduced carbon footprint. Architects appreciate the absence of pipes or controls around the device, which enhances the entrance’s aesthetic. Additionally, the property users are pleased with consistent indoor temperatures,” says Summanen.
Air curtains are also necessary in the summer when buildings are being cooled. During this time, the heater of the device is turned off, but the fan continues to operate. The air curtain prevents cooled air from escaping and keeps out the warm, humid air from outside. Humidity can lead to problems, such as with refrigeration equipment if it condenses.
During summer, the air curtain also keeps dust and insects out of the doorway. Otherwise, the benefits remain the same as in winter: comfort is enhanced and energy is conserved.
