    Test Conditions
    Location: Tested location of store is surrounded closely by other buildings
    Temperatures: 1. Cooling Test: Room Temp. (28 ), Outdoor Temp. (32 )
                         2. Heating Test: Room Temp. (0 ), Outdoor Temp. (0 )

    2. Other Benefits

    1)Comfort
    It minimizes distributed temperature differences and equalizes the overall room temperature.

    2)Cleanness
    It maintains cleanness by intercepting winged insects and atmospheric contaminants from outside

    Air curtain provides great value-added services such as cost reduction, sales increase and improved service quality while customers and employees experience a comfortable environment
