No, there is no difference in the sound level of the machines when installed inside or outside, but since air curtains circulate a huge volume of air, in very quiet conditions it may be disturbing.
Hence installing them outside gives better protection and even affects the feel of sound level.
We should install air curtains just above the door header or to a maximum of the half to two inches. The closer the top of the door opening is, the more effective the air curtain will be. Extended mounting brackets are available in various lengths so the air curtain can be mounted to clear an obstruction.
In no way Air Curtains should be taken more than two inches above the Door header, generally done in the case of Exed glass above the Door. People tend to put it above the Exed glass. In such conditions, air curtain efficiency will be severely affected.
Yes, air curtains can be used to hold extreme hot air on the industrial conveyor or oven. Actually, air curtains are very effective and can prove to be a great money-saving tool because a huge amount of money is invested in heating the air through heaters/boilers. When the difference between the ambient temperature and the hot air is higher, losing the air makes an exponential effect on the cost.
The installation of Air Curtains on hot ovens and powder coating conveyors is very different than normal horizontal installation, where the thumb rule says, “We install the air curtain on the warmer side.” On the contrary, when the temperature) in more than 200 C, the installation cannot be done inside and in such places, the installation is done in ambient air with air Bowing from bottom to top, with special mounting brackets. Air Curtains are very effective on hot ovens and can hold the hot air inside various advantages which they can give are:
- Fuel Saving
- Reduced chamber heating time
- Increased conveyor speed results in high production
- Reduced curing time
