Indoor air quality is one of the most overlooked health risks present today. The WHO is calling indoor air pollution “the world’s largest single environmental health risk”. Americans spend over 90% of the time indoors in air that is 2-5 more polluted than the outside.

PCO is photocatalytic oxidation. This process occurs when a semiconductor in the form of a photocatalyst is activated by a light source powerful enough to excite an electron to a higher energy state. This promoted electron will then react with ambient oxygen and water vapor in the air to create the hydroxyl and superoxide radicals. These radicals will oxidize harmful pollutants, bacteria, and viruses in the air.

Every organic pollutant entering our PLAN HVAC and 350 unit is degraded into their smallest safe constituent by our photocatalyst’s hydroxyl and super oxide radicals. These radicals are generated by light activation from 5 UVC bulbs inside our PLANT HVAC unit, or 1 inside our 350 unit. No free radicals leave our unit, therefore preventing the release of additional irritants in the room.

Promethium has incorporated a record-setting photocatalytic blend into an optimized geometry for both an HVAC and a standalone unit. This industry-leading catalyst outperformed the market standard, TiO2, by over 80x. What it takes Promethium’s catalyst to do in a second, TiO2 takes a minute and a half. This leap in performance enabled Promethium’s systems to confidently tackle commercial amounts of air continuously 24/7.

C-Band Ultraviolet (UVC) solutions are useful against pathogens but require substantial dosage and exposure time to the light source to be efficacious. PLANT systems effectively target and destroy, on a commercial level, not just bacteria and viruses but also gaseous pollutants and particulates at the low energy consumption of 285 watts

Filtration media works well at capturing particulate matter and some viruses and bacteria, but not well against gaseous pollutants, unlike the PLANT systems. Highly rated filters when saturated will impede the air flow significantly, decrease ventilation, have a negative effect on the air handler and overall system efficiency over time. The PLANT systems specialize in breaking down gaseous pollutants and pathogens in the air, with a system longevity of 5 years, and a low system impact. PLANT systems can decrease energy consumption by allowing for increased HVAC recirculation.

Gaseous pollutants, bacteria, and viruses are not being effectively targeted on a commercial scale. The technology exists to rid the air of gaseous pollutants, viruses, and bacteria on a small scale, but when trying to scale to commercial HVAC systems, technologies fall short. Whether it be a UVC only system requiring the energy consumed by a small home to destroy bacteria/viruses in a commercial HVAC system or a device that ionizes particles in the air that, counterintuitively, can produce potentially harmful byproducts. Promethium separates itself from the rest by cleaning the air effectively, energy efficiently and safely.

It depends on the air handler. The PLANT HVAC is reliant on the air handler for supplying the flow through the system. If an air handler is treating multiple floors, then yes, Promethium’s system can treat multiple floors.

The PLANT is very efficient in eliminating odors, namely cigarette, food, smog and many more. The PLANT systems break down volatile organic compounds (VOCs) and hydrocarbons which are generally the chemicals in the air producing a smell. Additionally, the PLANT system can utilize an activated carbon filter for an increase in performance in odor reduction.

Promethium offers a top-of-the-line wall mounted air quality sensor to test everything from CO2 to VOC levels in the occupied space.

If no particulate filters are installed with the PLANT HVAC unit, the unit will see a slight reduction in longevity compared to if the recommended MERV 8 activated carbon filter is placed before the system. This reduction is very slight because in most pre-existing HVAC systems, there will be a filtration rack with a minimum of a MERV 11 to MERV 13 particulate filter to capture the larger particulates before the entire Promethium’s system that specializes in gaseous pollutants and bacteria and viruses.

5,000 CFM is the largest volumetric flow rate for maximum treatment efficiency with a single PLANT HVAC. The PLANT HVAC was designed to slot into a standard commercial square duct size generally used at 5,000 CFM. The technology is not limited to the 5,000 CFM, It can be scaled to higher flow speeds but will require more than one unit placed in series to treat the air.

Yes, the PLANT HVAC and PLANT 350 run on 120/277V/ and 120/240V, respectively.

The warranty is different for each of the parts. Please reach out to sales@promethiumltd.com to discuss the warranty further.

Our PLANT 350 only consumes 0.075 kWh and our PLANT HVAC 0.285 kWh. If the units were to operate full time over the course of a year it would cost 78 dollars for the PLANT 350 and 166 dollars for the PLANT HVAC, using Nevada’s energy costs.
