ISOLAIR2 Chilled Room Air Curtain

ISOLAIR2 Chilled Room Air Curtain

The IsolAir2 chilled room air curtain is the perfect solution for indoor climate separation which does not require heating. Fitting an IsolAir2 air curtain above the doorway ensures an ideal separation between two temperature zones, whilst energy consumption is kept to a minimum. The air curtain is specifically designed for indoor climate separation where several climate zones are more or less constant. The IsolAir is applied in chilled rooms of production companies, distribution centres and in small cold stores in supermarkets.

Climate Separation without heating

When a building consists of several climate zones, an open inside door leads to air displacement and as a consequence energy loss. An IsolAir above an open door provides very efficient climate separation between the two areas limiting energy consumption

Technology

An air curtain above an open inside door provides climate separation of the two rooms. Whilst developing the IsolAir2, Biddle chose to use its well-known outlet discharge pattern, the Double Rectifier. The IsolAir2 is equipped with radial backward curved fans which homogeneously distribute the air across the whole discharge opening, producing high efficiency and comfort levels. If a conventional air curtain without a rectifier discharges air at the same velocity as a unit with a Double Rectifier, the downward penetration is tangibly less. The air stream does not reach the floor, and the open door is not covered off properly. Consequences include draught, loss of energy and comfort complaints.

Double rectifier
• Significant climate separation efficiency (80%)
• Excellent downward penetration
• Minimal air volume, air speed and heating capacity
• Energy efficiency

Controls

    Biddle MAT COLD STORE

    The MAT air curtain is used for climate separation between the cold store and the loading area in order to keep the temperature at a constant level in the cold store. Furthermore it allows unobstructed access to and from the cold store, radically reducing misting and icing and provides an energy saving solution.

    Energy Saving Hybrid Solution

    Energy saving solutions are becoming of great importance in the industrial and cold sector. In order to meet this trend, Biddle has developed the MAT Hybrid, which makes use of waste heat of cooling machines in order to save energy. In practice, up to 80% energy savings have been measured by applying the MAT Hybrid model compared to an equivalent electrical unit.

  • Indac2 Air Curtain

    Biddle INDAC2 Air Curtain

    The Biddle IndAC2 industrial air curtain is the perfect solution for separating climates in industrial buildings. Doors are often open for long periods of time to facilitate transport in and out of the building.
    The IndAC2 air curtain can be used for climate separation between indoor and outdoor environments and for indoor climate separation between two spaces with different temperatures.

    High Climate Separation Efficiency – Open doors cause energy loss and disturb the inside climate; the difference between the inside and outside temperature leads to an exchange of air, resulting in cold air entering and warm, heated air, flowing out. When the IndAC2 air curtain is mounted above or next to an open door it provides a very efficient climate separation at the lowest energy consumption.
