The Role of Air Handling Units in Hospitals

At Ductbusters’, we can apply the use of our air handling units in hospitals.

AHU can help to circulate around your buildings ventilation system.

How do Air Handling Units (AHU) work?

AHU works by taking fresh air and treating it. The treatment can be through changing the air temperature or cleaning the air.

There are many different components in the unit.

For example, some of these components include:

  • Heating and cooling elements
  • Filtration racks
  • Dampers and fans

Each of these components work together to supply clean air through your buildings’ ductwork. Furthermore, our AHU can recirculate air that has already passed through the unit. This is commonly known as recirc air.

The air handling unit introduces recirc air to fresh air. Additionally, the air handling unit pushes it back through the system. This process limits the amount of air conditioning your building requires.


The role of Air Handling Units in hospitals

AHU can help you ensure that the air in your hospital is clean and purified. AHU achieves this by pushing the air through different layers of filtration. Filtration helps to remove natural and man-made substance particles from the air. For example, some of these substances include:

  • Air pollution
  • Dust
  • Smoke
  • Toxins produced by the local environment inclusive of petrol and diesel emissions.

This system can help your hospital to provide a safer environment for patients. Our system reduces the risk of patients contracting illnesses while recovering.

Similar to ventilation systems, AHU can reduce cross-contamination of the hospitals air supply. Also, AHU controls the direction of air flow throughout your building. This helps to ensure that the air moves through clean areas and then to contaminated areas.


How we can help you maintain your Air Handling Unit

You should adequately and regularly maintain your AHU. This maintenance involves cleaning, regular filter changes and servicing. If you do not perform proper maintenance, dirt and debris can build up on the inside of the temperature coil. Also, it can build up in the internal structures of the AHU – for example, chambers, fan blades.

Furthermore, if you do not clean the AHU properly, it can disperse dirt through your ventilation system. With the air handling unit, it’s not only the dirt and debris which can affect the function of the unit. Condensation also poses a risk to air handling units. Where condensation is present in the AHU, it can cause corrosion on the floor or drip trays. To prevent this, we can apply coating to the areas exposed to condensation. This coating can help you avoid replacing a whole unit.
