Reasons why Fire and Smoke Dampers Fail to Work

Inspection of fire and smoke dampers are required in all buildings, whether commercial or residential. The inspection should be conducted every four years because over time the damper and the parts associated with them age out and break down. The damaged fire damper will only promote fire spread instead of preventing its flow.

Once the system is exposed to fire (with a non-functional fire damper), it is very likely to cause property damage and loss of lives. Regular inspection and maintenance can make your system work safer and run smoother and faster.

Using uncertified fire dampers

Laboratory tested fire dampers are safe to use because they are tested on different parameters. These dampers are certified to be used only when they succeed at all level test. The fusible link, flame detector sensors and all important factors are thoroughly examined for safe use of the device. But an un-certified damper is usually not tested for all these parameters, and so they are prone to fail during fire hazards.

Rust or corrosion

Most Fire damper suppliers in Dubai supplies dampers from metallic materials, like metallic sheets bolts and nuts. These elements over time get rusted and corroded. This often affects the functionality and integrity of motorized fire dampers. It prevents the damper from opening and closing at the time when it is highly required.

Damaged fusible links and physical damage

Fire damper suppliers in Dubai often tell that physical damage is one of the main causes of fire damper failure. Because parts of dampers get worn out, walked out and bumped into overtime. These issues change the shape and integrity of damper and damage its functionality as well. So the damage parts must be inspected from time to time and replaced. At times fusible links also get cracked and get broken, which cause it not work properly and allow the spread of flame inside the system.

All these factors should be avoided, and one should ensure using only certified fire dampers. When purchasing these dampers, make sure to get them from renowned and reliable fire damper manufacturers.

Types of Ac Ducts Along with Noted Features

Have you ever thought about the importance of AC ducts? There are so many different types of makes and models available, which are enough to proof the importance of ducts. These ducts are mostly termed as a passageway, used for free flowing of air into various other rooms. These ducts are available in various shapes and sizes, but the main ingredient remains the same; stainless steel. The products are known for their high tensile strength and longer working capacity. Therefore, once installed, you do not have to think about maintaining it.

Types and their qualities

There are primarily three different types of AC ducts available from reliable online stores. Those three options are galvanized iron duct, pre-insulated ducts, and mild steel ducts.
  • These ducts are mostly tailor made for matching customer’s requirements
  • These are further available in different grades and in various thicknesses
  • The duct pieces are identification tags, which are used for ensuring correct and quick installation services

Features of GI ducts

Among the three available options, people are inclining more towards galvanized iron ducts. The items are known for their mold resistant and non-combustion services.
  • Ducts are mostly available in aluminum and stainless steel services
  • There are some hot dipped sheets available with lock forming quality. These are mostly used for manufacturing standardized forms of ducts.
  • For re-enforcing, the straight ducts are beaded along with a distance of nearly 300mm between the available options.

Looking for the pre-insulated ones

Apart from the points mentioned above, you can further try your hands with ducting suppliers. The products are available with lower heat conductivity, along with higher thermal efficiency level. Moreover, the items are with lightweight materials and in lower density. These are further forms with CFC materials and environment protective. It comprises of the hermetic seal, which really ensures little air leak. On the other hand, you have aluminum foil around here, which offer reinforced from both the sides. Other than working on air conditioning ducts, you can even procure variable air volume systems from variable air volume system manufacturers. They are all set to help you out and make some requisite changes for your AC unit.
