Aerosol Duct Sealing Technology
Developed in 1994 by the Energy Performance of Buildings Group at Lawrence Berkeley National Laboratory, the aerosol duct sealing technology was designed to plug leakages in air distribution ducts. This cutting-edge technology works by injecting a mist of sealant particles suspended in air into a pressurized duct system. The crucial aspect of this technique is to prevent the suspended sealant particles from being deposited on duct surfaces until they come in contact with the leaks. At the point of contact, the sealants abandon the air stream and settle at the leak edges, therefore sealing the leaks.
The aerosolized particles are drawn to the leaks where they become deposited for the following reasons:
1. All the air which flows passes through the all the leaks as all the supply and return grilles are sealed for the interim
2. The continuous movement of air keeps the lightweight aerosol particles floating
3. Sharp turns made by the air stream exiting the leaks results in the collision of particles with the leak edges to which they adhere.
4. The adhesion of solid particles causes the seal to stop leaks as wide as one inch in diameter.
Advantages of aerosol duct sealing
Aerosol duct sealing is more advantageous than traditional duct seal methods because:
1. It seals more ducts leaks by getting to the most inaccessible leaks
2. It affords better working conditions and is less time consuming; Denair’s contractors spend very little time sealing leaks
3. It is less expensive for homeowners. This method has a high success rate and will not require subsequent sealing which. As a result, homeowners can save more money.
Mobile Aerosol-Sealant Injection System (MASIS)
Despite being the latest development in aerosol duct sealing, Denair HVAC is very familiar with this technique and is able to utilize it when dealing with sizeable commercial buildings. This method was specially developed for large commercial buildings and to accomplish numerous aerosol injection processes at the same time.
This system comprises an air compressor, a mobile cart, and a computerized sealing monitoring device. The aerosol-sealant injector is very compact and is the system’s most vital feature. This feature has numerous adaptations which allow it to carry out its functions more effectively than commercial aerosol injectors. These adaptations include:
• A sealing rate which is five to ten times greater
• A concentrated sealant
• Reduced heating power
• Compact size
• Minimally invasive installations
• Ease of servicing
