HVAC Air Conditioning




HVAC stands for Heating, ventilation, and air conditioning (HVAC). HVAC is the technology of indoor and vehicular environmental comfort. HVAC includes all systems from the home air conditioner to the large systems used in industrial complexes and apartment blocks. HVAC systems are usually mounted on the roofs of high-rise apartment blocks. Rooftop HVAC units are also often known as air handlers - they are large HVAC system that is placed on a rooftop in order to moderate the temperature of a large space. Egana manufactures AV mounts for these HVAC units.

HVAC Construction

A heating HVAC is enabled using Gas, oil, coal, and electricity. On the other hand a chilling HVAC consists of a chiller, gas air conditioner, electric air conditioner, and electric heat pump.There are multiple types of HVAC system including Variable Volume HVAC System, Constant Volume System, Packaged Heating and Cooling HVAC Systems, Hybrid Heat Split System, Heating and Air Conditioning Split System and many more. HVAC systems can also be built to offer humidity control, and both humidifiers and de-humidifiers can be added as options to heating and cooling HVAC systems.

HVAC Air Conditioning Anti-Vibration mounts

The Need for Vibration Control in HVAC Systems

HVAC systems are typically packaged inside canopies and moduled to be easily placed on rooftops of apartment blocks or commercial buildings. These big box type canopies that are installed on top of office or apartment buildings contain machinery parts like blowers, heating and cooling elements, filter racks, and chambers and dampers. These boxes typically connect with the building ventilation system through a duct, that will then distribute the air through the building before returning it to the HVAC box to either discharge or return air back into the system (depending on the type of HVAC system).

Almost all HVAC Units - Make-up Air Units (MAU), Air Handling Units (AHU), and Rooftop Units (RTU) have internal vibration isolation dampers for the intake and exhaust fans. These exhaust fans have typical operating speeds that range from 400 rpm to 1200 rpm. There are a number of reasons for using vibration isolation for the isolation of exhaust fans and chiller units inside the HVAC system. These vibration dampers or AV mounts reduce the excitation of the building structure produced due to the vibrations produced inside the HVAC units. The AV mounts also help in reducing the fatigue failure of HVAC cabinets.

Overall, the Anti Vibration mounts allow building owners to install complex heating, ventilation and air-conditioning - HVAC systems on their rooftops without the worry of noise and vibration problems.

HVAC-system-av-mounts Advantages of EGA Anti-Vibration mounts



Why choose our HVAC Air Conditioning mounts

Egana has been providing Vibration Damping solutions for industrial machinery like generators, compressors, pumps, engines and heavy duty fans for more than 50 years. The main aim of using an Anti-Vibration mount in any moving machinery is to reduce the amount of vibration that the machine transmits to the frame and the surrounding structure and buildings. EGANA's Anti Vibration mounts provide the following advantages:

-> Natural Rubber Construction: Natural Rubber has the ability to accept and recover from extreme deformation of 200 percent or more. Our Rubber compound is formulated with the utmost precision to make sure that our rubber compound has longevity, resilience, resistant to high temperature variations and good ability to bond with metals. Another important characteristic of our rubber compound is it's ability to dissipate hear when it is subjected to continuous vibrational forces.
-> Superior Vulcanization Techniques: Our Anti-Vibration mounts are made by vulcanizing the specially formulated rubber compound at high temperature and pressure. The vulcanized rubber molecules so formed have higher polysulphidic crosslinks which are much stronger. This vulcanization technique has been perfected over the years with our final moulded rubber products which are far stronger, last longer and provide the highest possible vibration absorption.
-> Metallic Bottom and Top Dome: Our EGA and EGA-MARINE series of AV mounts come with metallic plates on the top and bottom with a layer of rubber sandwiched in between to provide the vibration absorption. The metallic dome at the top prevents the rubber mounts from oil, water, dirt, ozone degradation and other harmful chemicals that the machine might be exposed to.
-> Fail-Safe Design: The EGA and EGA-MARINE series of Anti-vibration mounts are equipped with a metallic fail-safe. This fail-safe design ensures that the engine and the alternator are securely connected to the main assembly frame of the HVAC cabinet. This prevents the machinery parts from toppling over while transportation or in mobile installations.
-> Versatile and Compact Design: Our HVAC AV mounts can be mounted on both external and internal generator frames. The compact design of the av-mounts provide easy fitting below the pump and fans in the HVAC assembly. Our range of AV mounts are suitable for damping vibrations in HVAC systems weighing from 100 Kgs to 12,000 Kgs.
-> Premium Quality yet Economical: The HVAC AV mounts are manufactured in our highly efficient presses which churn out multiple mounts in a single run. This provides us the opportunity to provide our generator mounts with the highest quality yet in very economical prices. In most of the cases a complete set of our anti-vibration mounts for generators works out to less than 1% of the total cost but provides substantial advantages.
-> Product testing and quality certifications: We have extensive facilities and engineering resources to perform product, material and vibration damping tests under real-world conditions.

It’s important to keep in mind that picking the wrong Anti-Vibration mount for your HVAC system could actually make vibration worse than if there were no mount at all. We recommend consulting with a vibration control expert early in the product design process when selecting the materials and mounts for any HVAC system.

HVAC systems in UAE

There have been recent regulations in Dubai that have made the installation of additional power generators in huge buildings and landmark projects a must for any contractor or company. These backup power generators need to be fully functional meeting all essential services including elevators and emergency lights. Real estate developers will be installing additional power generators at projects under their portfolio within UAE. With these generators being installed in residential/commercial locations, it is imperative that they do not produce excessive noise and vibration. According to the buildings department of Dubai Municipality (DM) there are close to 26,000 buildings under construction as of June 2017. With each building project, as per the regulations back-up generators need to be installed - hence there is huge demand for generators within UAE.

Egana has been supplying their anti-vibration mounts to reputed generator manufacturers in UAE and Middle East. With the highest focus on quality products providing maximum vibration isolation, Egana's EGA mounts have been the first choice for all generators manufacturers and generator canopy manufacturers in the MENA region.
