What are the types of AHU?

 AHU or Air Handling Unit or Air Handler handles the air to be supplied through the ventilation ducts into the building and return it to the AHU. Basically, to ensure that air is delivered with thermal efficiency. The AHU treats the air by filtering, cooling, and / or heating, humidifying or dehumidifying. Air handling units are important part of HVAC systems, both in residential and commercial areas.

An AHU is a metal box having multiple components, channel racks / chambers and dampers which can have design variation as per requirement. Air Handling Units (AHU) with double skin panel construction are Hygienic.

Trosten is one of the best AHU manufacturer in the UAE and their AHUs are certified by TUV Nord, Germany.

We can classify the AHUs as per their usage.

• Terminal Units are small AHUs for local use. They may have only an air filter, coil and a blower.
• Makeup Air Units are large Air Handling Units that condition the outdoor air 100%. They do not circulate the air again.
• Packaged unit is also known as Rooftop Unit (RTU) is designed for outdoors, like roofs.

Let us look at the components of Double Skin Air Handling Units.

• Blower: One of the most important components of the Double Skin AHU, it helps recycle air in a building. The air inside a blower is properly conditioned.
• Filter: Filters help to remove the dust and other contaminating particles.
• Conditioning elements: They help heat or cool the air, as per the requirement.
• Humidifier: This help maintain the air quality in cold climatic conditions.

Regardless of the kind of AHU, regular maintenance and servicing is an absolute must. This ensures an increase in the durability, functioning and longevity of the Air Handlers.

Trosten manufactures AHU with both direct expansion and chilled water system, after thoroughly understanding the need of the market. The capacity of the Trosten Double Skin AHU varies from 600 CFM to 80,000 CFM, thus making them an ideal choice for big HVAC systems as well.

Trosten has ensured that there is the least chance of microbial growth in its HVAC units installed with its double skin AHU. These AHUs are energy efficient.

Trosten ensures best product quality and customer service.

All about Eurovent certified Air Handling Units

 

Eurovent classification is a new classification specified in the rating standards from 1st January 2016. As per the standards certain critical parameters are taken in to account to determine and efficiency of the air handling units. Eurovent certified air handling units consists of a fan or other accessories to perform the functions like circulating, heating, filtrating, humidifying, heat recovery etc. They are suitable to be used in the duct works. Air handling units are available in different sizes and units of same sizes are grouped under the same designation by using the similar selection procedures.

Air handing units are useful in establishing mechanical, thermal and acoustic performance according to manufacturer’s specifications. Eurovent certified air handling units offer several certified mechanical and performance characteristics like heating capacity, cooling capacity, heat recovery, static pressure, acoustic insulation of casing etc. A unit classified under ‘A’ category as per Eurovent clarification represents at least 28% more efficiency than the units formerly classified under ‘A’ category.

 Trosten Industries supplies certified centralized air conditioning and kitchen ventilation equipment for residential, commercial and industrial applications. They are considered to be among the top Eurovent certified AHU manufacturers in the GCC region. The Company offer services to the customers by offering high ecological returns.

Differences between regular AHU and Hygienic AHU

Commonly called an AHU, an air handling unit has now become essential in many residential and commercial areas like data centers, hospitals, laboratories, offices etc to cool the indoor environments. It consists of a large metal box containing a blower, heating or cooling elements, dampers, sound absorbers and filter racks. Trosten specializes in manufacturing hygiene units with different configurations built to promote higher levels of hygiene in hospital environments all across the GCC region.

 So, what are the differences between regular AHU and Hygienic AHU?

 An air handling unit (AHU) filters and controls air quality in the indoor space with its air purification filter. These filters are intended for spaces where natural ventilation is limited and there is a crowd of people walking in and out of the premises. These AHU’s collect air from outside, which is treated and distributed throughout the rooms after being recycled.

 It regulates the air conditioning and conditions the temperature so that the environment is set to a comfortable temperature.

It monitors the humidity levels and with heat recovery units AHUs can reduce the consumption of energy needed in an air conditioner. The indoor and outdoor air is mixed so that when the air comes in contact with the coil the temperature contrast is lower making the climate contribution also lower. Some components of an AHU are

 ●      Filter: It purifies the air and can be adjusted according to the air purity requirements to filter out bacteria, air pollutants and viruses.

●      Fan: This electromechanical system powers the air to expel unhygienic air from the AHU to the ducts.

●      Heat exchangers: These devices transfer temperature between two fluids - the coolant and the air which is then separated by a solid barrier. 

Hygienic Air Handling Units or Hygienic AHUs are used in industries that need to give importance to maintaining a sensitive sterile environment and maximise hygienic conditions. They are used in pharmaceutical and medical industries, operating theaters and food industries.

It provides greater efficiency than a regular AHU in terms of filtration and is installed to better manage the indoor environment while reducing energy consumption and avoiding the spread of bacteria. Its hygienic sound absorbers are placed in the AHU to reduce the dust particles in the ductwork.

Hygienic Air Handling Units are coated with stainless steel and are covered with special joining pieces and sheets to prevent water accumulations and present a straight and smooth surface.

Trosten offers high quality air handling units that elevate the performance of centralized heating, ventilation and air conditioning equipment for various industries.
