Torpedo targets ducted system safety

Following concerns surrounding recirculating air in buildings, JenAct says its UV Torpedo in-duct air disinfection units can keep ducted air conditioning systems 99.99% SARS-Cov-2 free and operational.

The UK’s Health & Safety Executive has said that the risk of air conditioning spreading coronavirus in the workplace is extremely low “as long as there is an adequate supply of fresh air and ventilation” but adds: “... if you use a centralised ventilation system that removes and circulates air to different rooms, it is recommended that you turn off recirculation and use a fresh air supply.”

JenAct, part of the Jenton Group, says its UV Torpedo systems are suitable for installation into HVAC systems and existing ducting, as well as for irradiation and cleaning of chiller coils. 

“The recent concerns about recirculating HVAC systems mean that many businesses have their air conditioning turned off,” said Dr Jarek Bilek, JenAct’s Technical Director. “However, our UV Torpedo disinfection units can be retrofitted to many systems to allow them to be turned on again and actually improve air quality by disinfection from viruses of all the air passing through.”  

The UV Torpedo system provides UVC disinfection energy, which destroys microbial, biological and chemical contaminants as they pass through the duct, drastically improving the air quality.

The UV module consists of high output UVC lamps mounted on the custom-designed polished aluminium reflector. The UV Torpedo is mounted parallel to the air stream in order to maximise the contact time of the contaminants with the UVC energy, cleaning the air as it flows past the UVC lamps.

JenAct’s proprietary UVC modelling software, developed over many years, allows UV systems to be accurately sized depending on air flow and duct dimensions. 

JenAct is a participating member of the International Ultraviolet Association and holds a number of granted patents in UV generation and application. The company has been based in Whitchurch, Hampshire since 1996 and says it is actively designing, developing and manufacturing solutions for the current Covid-19 situation.
