HVAC Mounting Accessories in Georgia

What are mounting accessories?

Mounting accessories are the elements that provide the physical fixing of the main ventilation equipment and ducts and their correct connection to each other.

With their help it is possible to fix a duct to a ceiling or wall, connect profiles to each other, create a support structure for a ventilation unit, fix pipes and ducts, control vibration and movement, reinforce mounting joints and build a stable structure for technical maintenance.

A ventilation system does not consist only of a fan or a duct. It is often exactly the small mounting parts that determine how correctly and reliably the system is assembled.

Where are mounting accessories used?

Mounting accessories are used in practically every type of HVAC system: in the installation of round ducts, in rectangular ventilation ducts, for fixing fans, for air heaters and other equipment, in profile systems, in pipework installation, in ceiling suspension structures and in commercial and industrial facilities.

How to select a mounting accessory

1. What are we fixing?

First you need to know what has to be fixed: a duct, a profile, a fan, a ventilation unit, a pipe or another technical component. For example, a small diameter duct and a heavy ventilation unit require completely different fixing systems.

2. What weight does the fixing have to carry?

The load capability of the accessory is one of the main parameters. The total weight can include the duct, the insulation, the equipment, the profile itself and other mounting elements.

3. Where is the installation?

The fixing solution also depends on where the system has to be mounted: a concrete ceiling, a metal structure, a wall, a technical shaft, an industrial space or an outdoor environment. Different surfaces may require different types of fixing.

4. What is the working environment?

If the system works in a humid environment, outdoors, in a corrosive environment or at high temperature, the material and protection of the fixing component also have to be considered.

What types of component are included in mounting accessories?

The specific range differs depending on the system, although mounting accessories often include fixings, suspension parts, connecting pieces, anchors, threaded rods, nuts and bolts, profile clamps, clamps, rubber or vibration isolation elements, and auxiliary plates and connectors. These elements often work together and form one complete mounting system.

Why is correct load assessment important?

A mounting system has to maintain mechanical stability throughout the whole period of operation. If the load is calculated incorrectly, the result can be a sagging duct, deformation of the structure, overloading of the fixings, increased vibration, excessive noise and damage to connections. For large and heavy HVAC systems the mounting parts should therefore be selected as carefully as the main equipment.

Why does vibration control matter?

Fans, motors and other mechanical equipment generate a certain amount of vibration while running. If this vibration is transmitted directly to the building structure, it can cause additional noise, duct vibration, load on the fixings and discomfort in the building. In a specific system a rubber pad, a vibration isolator, a flexible connection or a special fixing may therefore be required.

Why does compatibility matter?

Mounting components have to be compatible with each other. The size, thread type, profile shape, fixing construction and load capability all have to match. A component that is incorrect or forced into place cannot provide a reliable installation.

What are the most common mistakes when selecting mounting accessories?

Selecting by size only

Different fixings of the same size can have different load capabilities.

Choosing the cheapest part

The quality of a mounting element affects the reliability of the whole system.

Not considering the total load

The weight of the insulation and other components has to be taken into account as well, not only the duct.

Using incompatible components

The profile, fixing, nut and other parts have to fit correctly within one system.

Ignoring the mounting surface

The same fixing is not always suitable for concrete, brick and metal structures.

How to select mounting accessories in practice

Before selection it helps to know:

• what component has to be fixed;
• its size and approximate weight;
• where the installation takes place;
• what type of surface it has to be fixed to;
• whether a mounting profile is used;
• the distance between supports;
• whether vibration isolation is required;
• what the working environment is;
• what other fixing elements it has to be compatible with.

With this data the complete mounting system can be selected more accurately.
