MITSUBISHI ELECTRIC GK-3512SA-AUS Air Curtain Industrial & Light Commercial Usage Front Inlet – 1180mm

Mitsubishi Electric air curtains are the perfect way to provide your premises with a comfortable, clean and hygienic environment while saving energy with a quiet, efficient and powerful operation.

The air curtain not only insulates temperature efficiently (i.e. preventing loss of cool air during cooling and heat loss during heating) it can protect your premises from unpleasant elements found in the external environment.

Sustains Temperature
An air curtain can help retain conditions inside a cold storage facility. In a cold-storage facility without an Air Curtain, temperatures near the door can increase by 4-10 ºC in as little as two minutes for every time the door is opened. If an Air Curtain is used, this time is extended to about 10 minutes, or approximately five times as long. Tests show that when an Air Curtain was used, lesser energy was required to reduce the inside temperature to -5ºC.

Adjustable Airflow Angle
The airflow angle can be altered both internally and externally by adjusting the installation angle of the main unit.

Flexible Installation
The unit can be installed vertically or horizontally according to the available space.

Shut-Out
Powerful airflow lock out. Keeps out dust, insects, and noxious odours. Helping maintain a pleasant environment.

* In an insect shut out test, a 40 w mercury lamp was placed inside an Air Curtain ejected from a 4 cm wide vent at a velocity of 8 m/sec. The insect shut out rate was 70-80%.

Rectification plate
The rectification plate creates a high-speed current in a single direction, by transferring airflow from the propeller fans without reduction of volume or velocity.

Zoning in open spaces
The air curtain can invisibly shut out areas that do not require air conditioning. For example, there is no need to air condition the lane side of a bowling alley, so the air curtain acts as an air conditioning zoning device.
