UVGI For HVAC

UV-C Air Sanitisation Equipment

The UVC-19 Compact Ultra-Violet Sterilisation Unit has been designed to fit all standard ceiling cassette air conditioning units.

UVGI is a proven method for removing volatile organic compounds(VOCs) and for killing or deactivating bacteria, viruses, mould spores and other pathogenic microorganisms that may be present in room air.

Why does UV-C work?

UV-C is already commonly used in hospitals air and water systems, including microbiology labs etc. UV-C is one of the most effective ways of killing germs and viruses quickly without the need for strong chemicals and without leaving any residue.

High strength UV-C, measured in wave lengths of between 100 nanometre (nm) to 280 nm, emits highly effective sterilisation power. Our equipment uses UV-C lamps  set at around the 254nm which provides the most effective sterilisation killing both air bourne and surface microorganisms and viruses. UV-C rays in the 254 nm wavelength attack the DNA and paralyze all cellular functions in bacteria, viruses and even antibiotic-resistant superbugs leaving them unable to multiply and therefore considered inactive or dead. SARS-CoV-2, the virus responsible for Covid-19, can be inactivated by exposure to UV-C.

CALMEC’s Range of UV-C units have been specifically designed to fit the different types of ventilation and air conditioning systems commonly used in commercial buildings. CALMEC has extensive experience in the design, supply and install of ventilation and air conditioning systems and will be able to recommend the most effective units for your existing or new ventilation systems. We also have a team of installation engineers covering most of the UK if required.

Allowing reopening of offices and factories with recirculating ventilation and air conditioning systems.

The install of CALMEC UV-C units to existing building ventilation systems will give the owner, building manager and their employees the added confidence, along with all the added measures already in place, to return to work during this coronavirus outbreak, allowing the heating and cooling ventilation systems to be used safely.

One of the main benefits of our duct mounted systems is that they add virtually no additional resistance to an already installed system and therefore no fan upgrades will be required. They use very little power and would not normally require a new power supply. They also require little maintenance unlike filter systems.

Application Areas

Hospitals

UltraCoil & UltraDuct systems destroy high levels of airborne and surface bio-contaminants. Infections Acquired in Hospitals (HAI) can be a significant cost for the healthcare industry and is considered a preventable injury. Ultra IAQ systems are the ideal tool to help reduce nosocomial infections.

Pharmaceutical, Food Processing And Produce

Air quality and the risk of surface contamination play a vital role in pharma clean rooms, and in the production & packaging of food products. UV Sterilization of both air and/or surface of product or packaging by UltraHVAC UV systems can dramatically reduce the possibility of contamination.
In fruit/vegetable markets it can extend the life of the produce by destroying the off-gassing (i.e ethylene) which cause faster ageing.

Commercial Spaces, IT Parks and Schools

A WHO report suggested up to 30% of new and remodeled buildings worldwide may be subject to complaints related to poor indoor air quality, the leading cause of “Sick Building Syndrome.” According to the EPA, poor indoor air quality can directly affect the health of students, staff, employees, which in turn affect attendance and performance. Using UltraHVAC UV systems significantly improves air quality resulting in lower absenteeism and higher efficiency.

Hotels and Leisure

CALMEC can provide solutions for most environments and can include a complete mechanical maintenance package of all HVAC and Mechanical plant and equipment.

When you need flexibility

UV Light

The twin rack lamp arrangement has been positioned to create the most comprehensive microbiological destruction zone possible, with the internal reflective surfaces adding further to the unit’s formidable single-pass performance. Ideal for high risk medical situations or exacting commercial applications.

To maximise flexibility, this model is designed to allow multi-assembly of units to accommodate any given air volume or required plant position.

Manufactured to exacting standards, the outer case is fabricated from 1.0mm thick galvanised sheet steel, epoxy polyester treated with aluminum anacoil internal liner and stainless-steel lamp racks.

UVG 2000 – In-Duct Single Rack Unit.

The UVG 2000 unit is one of the most powerful and efficient air sterilisation unit of its type. The twinrack lamp arrangement has been positioned to create the most comprehensive microbiological destruction zone possible, with the internal reflective surfaces adding further to the unit’s formidable single-pass performance.

The Performance is backed by extensive scientific testing with verifiable results and is Ideal for high risk medical situations or exacting commercial applications.

Manufactured to exacting standards, the outer case is fabricated from 1.0mm thick galvanised sheet steel, epoxy polyester treated with aluminum anacoil internal liner and stainless-steel lamp racks.

For total peace of mind, the unit comes with a unique visual lamp monitoring system to facilitate easy identification and replacement of individual faulty lamps. A dedicated volt-free plug is provided to allow connection to an external monitoring circuit.
