Active Airflow UV-C Fixture
Research indicates that most viruses and bacteria are spread by breathing airborne particles. Studies conclusively show that ultraviolet light (UV), particularly UV-C spectrum (265-280nm) is especially effective in eliminating these pathogens.
What is UV-C Light?
• Ultraviolet Light is between 100nm and 400nm
• The wavelengths between 222nm and 275nm are the most effective for germicidal eradication effectiveness.
How Does UV-C Work?
UV-C is a very powerful Ultraviolet light wavelength, and it covers a region where viruses and other pathogens are most susceptible.
We call this the Germicidal Effective range, and it peaks around 268nm – 270nm.
When bacteria, germs or viruses are exposed to a full DOSAGE of UV-C in this range, it damages the DNA, leaving it unable to function or reproduce.
How Does Energy Harness UV-C Work?
The Energy Harness UV-C technology uses
precise 265nm and 275nm high powered LED chips to eradicate the pathogens while the airflow is passing through the fixture.
Designed to be effective and safe, the UV-C Active Airflow fixture circulates room air many times per hour through its encapsulated UV-C
light, eliminating virus pathogens while keeping humans safe.
Built with the most advanced solid state LED technology, it delivers precise UV-C dosages for effective, quiet and reliable operation.
What is UV-C Dosage?
Precise dosage delivery is controlled by using high powered UV-C LED chips (265nm and 275nm wavelength) for a predetermined exposure period.
Each different type of microorganism will require different dosage amounts to sufficiently damage the pathogen.
*Nominal Ultraviolet dosage (mWSec/cm²) necessary to inactivate better than 99% of specific micro-organism / microbe.

Frequently Asked Questions & Answers
Can this device or technology kill the Covid-19 virus?
The use of UV-C in eradicating pathogens is highly effective but requires that a proper UV-C dosage be delivered with the following combination: 1) the wavelength of the UV-C must be in the germicidal effective range (approximately 268nm peak), 2) the intensity must be high enough to irradiate the space, 3) the duration must be long enough to affect the organism. (Wavelength Intensity * Duration) = dosage delivered.
The Active Airflow UV-C Fixture delivers all three of these required parts to deliver a high level or calculated and tunable UV-C dosage.
What is the maximum room size/area that the unit covers? Is it possible to install in locker rooms, weight rooms, band rooms, nurse’s offices, etc.?
The fixture can circulate the air in a 16ft x 16ft room with 9-foot ceiling. Multiple fixtures can be used in the same room. The fixture can be placed into a standard drop ceiling grid, or for higher ceilings, it can be hung by suspended chain and lowered to the proper height. It can also be wall mounted or surface mounted on solid ceilings. The fixture can be mounted in any orientation, vertical or horizontal, so that it works as well on the ceiling, wall, or on a stand.
What type places are interested using this technology, and where is it being installed specifically?
There are many school systems (private and public) and school administrative offices, as well as hospitals, medical outpatient buildings, waiting rooms, exam rooms, and dental offices using this technology. In addition to regular office buildings and suites, post offices, city hall administrators, fire departments with living quarters, police departments, DMVs, tax collector offices, permit offices and Emergency Operations Centers are also utilizing it. These fixtures are also appropriate for airports, supermarkets, gas stations, shelters, restaurants, processing facilities, churches, gyms, and other highly trafficked public spaces.
Do we have any case studies of where this technology has been applied?
Yes, studies on the germicidal effect of ultraviolet light and its effects on microorganisms have been published as far back as 1877. This UV-C technology has been used for over a hundred years, and the technology has continued to improve since that time. Philips is a major contributor with a recent study using Boston University and Covid-19. UVC sterilization has been a standard protocol for hospitals and laboratories for many years. The LED solid state device has advanced the UV-C by providing a stable LED chip that can deliver precise high dosages of UVC with a specific nanometer range. The Energy Harness website will continue to provide an extensive library of published UV research and answers.
What certifications do we have for this product/solution?
Our product and technology are Patent Pending with the US Patent Office. The products are going through UL certification for all safety aspects. We are partnering with universities to provide ongoing LED and UVC technology studies. The products are being tested by biotechnologies testing laboratories for airborne pathogen effectiveness.
When will this product line reach full production capacity?
Medium production runs are currently underway with large-scale production achieved early in the fourth quarter of 2020.
What is the warranty and maintenance plan?
The Fixture is covered by a three-year warranty on the chassis, electronics, and fans. The LED modules (UV-C 265nm and 275nm chips) have a 3000-hour warranty (8.2 hrs./day/1 year).
For most customers this is a module that is replaced once per year. The LED modules are fully “plug and play” replaceable and are designed to last one year at 8-hrs use per day.
How loud are the fans inside of this product?
The current fixture design utilizes a single 34 or 36dB low noise fan module. There are no other parts of the fixture that create sound.
Is there a risk of danger for UV exposure if the fixture becomes damaged or is opened while in use?
The UV-C light source is located inside of sealed chambers, and under normal operation, there is no danger. The fixture is designed so that it cannot be opened if the power is still connected.
The fixture should not be powered on or operated in any way if it is damaged or disassembled. The UV-C light is dangerous to humans and can cause damage to the skin and eyes. Please call your sales representative for repair or replacement.
Where do you install these fixtures inside the room to get the best results?
Every room or area will have different airflow characteristics, and it is important to use the rising or circulating airstreams to feed the fixture input. The output side of the fixture can be directed towards people normally located in the room or toward calm spots that the HVAC system does not move or stir.
Wall mounted fixtures can be used to further circulate or clean the air in areas of high human traffic or constant human interaction.
Does the product maintenance have to be performed by a qualified electrician?
Periodic maintenance will be to clean or change the air filters. This can be performed by any maintenance personnel.
The annual or semi-annual maintenance (depending upon hours/day used) can be performed by an Energy Harness technician, site maintenance staff, or by trained personnel. This work is normally performed on a ladder if the fixture is ceiling mounted and should be performed by qualified personnel only.
