ME21 Air Curtain Pros and Cons

How it works?

1. Insect Control - Sanitation maintenance applications require that air curtains prevent airborne insects from entering. For fly and insect control, the air curtain projects the high velocity air jet across the opening, deflecting and prohibiting the entrance of unsanitary insects, thereby maintaining sanitary conditions. For applications such as fly and insect control which require maximum protection, it is common and accepted to use a more powerful air curtain in order to achieve the necessary level of protection.

2. Thermal Barriers -

the air curtain prevents the natural flow of air caused by differing temperatures. The difference between indoor and outdoor temperature creates an imbalance in density, and therefore a pressure variation which causes the infiltration of outside air.

3. Wind Resistance -

In many instances the infiltration of unconditioned air is driven by a combination of the temperature difference and the added problem of a prevailing wind at a door opening. Air curtains resist this infiltration of outside unconditioned air by blocking and deflecting the incoming wind. Wind resistance is achieved by using a well-designed air curtain with an appropriate velocity and volume of air, directed at the appropriate angle at the exterior doorway.

4. Separation of Indoor Environments -

In many facilities there often exist manufacturing or production areas adjacent to either offices or other clean environments, such as shown in Figure 5. The production side may generate fumes, dust and heat which are undesirable in the adjacent areas. Air curtains are ideally suited for these applications, repelling the undesirables without restricting traffic. The air curtain is mounted on the clean side so as not to circulate the contaminants through the unit, as well as to prevent blowing the contaminants into the clean side.

Savings Keeping HOT air in By fitting a air curtain over frequently opening entrances, whole building heating costs can be reduced by up to 30% as a result of lower heat levels escaping the building.

Keeping COOLED air in In summertime when air conditioning is used to cool the building, a air curtain used in ambient* mode helps to maintain the cool interior climate from escaping the building cutting running costs and improving comfort levels.

Increased Building Efficiency Air curtains help cut carbon emissions by reducing energy loss from opening doors, increasing the whole building efficiency.

Reduced CRC Tax Burden With efficient air curtain systems in place, carbon emissions reduce and the tax burden on the business lowers as a result, helping ease the financial burden.

Reduced Demand for Carbon Credits With the air curtain contributing to a better carbon footprint, there is less demand to buy carbon credits, saving money.

Increased Revenue from Carbon Trading By having effective air curtain systems, carbon emissions drop and the business can generate revenue from selling carbon allowances no longer needed.

Reduced Energy Bills As the air curtain reduces building heat losses, a corresponding reduction in building HVAC running costs can be enjoyed, year after year

Increased User Comfort By protecting occupants from cold draughts, a more comfortable environment will be provided with less reliance on occasional heaters, also cutting heating costs.
