Alfaa UV, one of the world leaders in UV technology offers a spectrum of UVGI solutions for HVAC applications, surfaces, and upper air. With more than two decades of expertise and experience, Alfaa UV has successfully implemented UVGI solutions in commercial, industrial, and municipal HVAC systems.

Over the years, Alfaa UV has discovered that many organizations still use outdated HVAC systems which cause a series of health problems for people. Let’s understand this in detail.

Why do You Need to Upgrade Your HVAC System in First Place?

An HVAC system is designed to filter and clean pollutants and contaminants from the air. Hence, they have proven effective to improve Indoor Air Quality (IAQ) in homes, hospitals, hotels, offices, shopping malls, and other commercial and industrial spaces.

However, HVAC is also prone to microbiological and biofilm growth. When the unit cools and heats, it leads to condensation which in turn results in wet patches of water. This water may seep into evaporator coils, causing the risk of spreading viruses and bacteria through air. Due to this reason, the use of HVAC became debatable after the onset of the COVID-19 pandemic.

What does Research Say?

A study by two professors at East Carolina University highlighted that coronavirus can be detected in HVAC systems. Another study published in the PLOS journal found that HVAC systems have the potential to transmit small aerosol particles, which are one of the reasons for the spread of SARS-CoV-2 in indoor spaces.

Traditional HVAC systems lack the efficiency to meet the demands of today’s IAQ and reduce the risk of coronavirus transmission. Even if you install add-ons such as ventilators or air purifiers, they lack compatibility. Hence, you need a powerful solution like UVGI to upgrade your HVAC system.

What is UVGI and How is it Beneficial For HVAC Systems?

Ultraviolet Germicidal Irradiation (UVGI) is a disinfection method for air, water, and surface. It is an electromagnetic radiation technique that inactivates and destroys viruses, bacteria, spores, molds, and other microorganisms by emitting UV-C rays at a wavelength of 200-280 nanometers.

In fact, a study conducted by Hiroshima University researchers discovered that UV-C light with a wavelength of 222 nanometers which is safe to use around humans kills SARS-CoV-2 effectively. One more scientific report also confirmed that UV-C light (222 nanometers) safely and inefficiently inactivates airborne human coronaviruses.

Even ASHRAE endorses the use of UVGI in HVAC systems to improve IAQ and reduce airborne diseases transmission. You should consider equipping HVAC units and air purifiers with UVGI for the following reasons:

  • Remove viruses, bacteria, mold, fungi, and microbes from the cooling coil and drain pan.
  • Curb the risk of disease transmission.
  • Eliminates Volatile Organic Compounds (VOCs).
  • Get higher energy efficiency.
  • Ease out allergy symptoms.
  • ‘Sick Building Syndrome’ (a condition in which building occupants suffer from acute health symptoms).
  • Reduce HVAC maintenance costs.
  • Promote health and safety.

Alfaa UV’s UVGI air disinfection for HVAC systems provides the much-needed protection to prevent the spread of bacterial and viral infections such as coronavirus. Apart from being a cost-effective and eco-friendly solution, it is also a safe mechanism to create a germ-free environment.

Alfaa UV offers two solutions for UVGI for HVAC systems:

  1. UltraCoil

This solution ensures the deep cleaning of coils in the safest and most eco-friendly way. The UltraCoil has a unique Parabolic Reflector System which proactively removes the biofilms (layer of slimy, sticky substance that houses the bacteria, viruses, mould, spores, etc.), thereby ensuring that the air does not get contaminated through the coil and drain pans.

  1. UltraDuct

This solution provides assured single pass disinfection of airborne bacteria and viruses. It is installed in supply or return ducts. The UltraDuct also increases the life of HEPA (High-Efficiency Particulate Air) by reducing the load of live organisms.
