Hydroxyl Generator with Advanced Oxidation Process, Treats Up To 4,500 sq ft

BoiE Hydra Hydroxyl GeneratorsThe BoiE HYDRA PRO V2 is a PhotoCatalytic (PCO) hydroxyl generator with an Advanced Oxidation Process (AOP) mode for challenging restoration projects including water and fire damage restoration, mold remediation and odor control. The PRO V2 is a new version of BoiE's HYDRA Professional, a fanless model that used germicidal UVC optics shielded by an air mover purchased separately.

Like its predecessor, the HYDRA PRO V2 can attach to a standard air mover to utilize the air mover's high air changes per hour (ACH) to quickly clean contaminated air. Additionally, the PRO V2 has a built-in 500 CFM fan and a front germicidal UVC shield that allows the PRO V2 to operate as a stand-alone hydroxyl generator in occupied areas. When a separate air mover is added, the PRO V2's fan is switched off and the unit's UVC shield is replaced with an air mover connection flange.

Along with PCO (safe mode), the HYDRA PRO V2 offers an optional AOP mode to accelerate hydroxyl production in the presence of germicidal (UVC) light. The PRO V2 can be operated continuously in PCO mode with occupants present, or in AOP mode with monitoring and appropriate PPE.* Both modes are safe for plants and sensitive materials.

The HYDRA PRO V2 has an IPX7 certified enclosure designed for the harshest environments on the planet and can be opened for service and locked for safety. Includes a straight-blade power inlet that accepts standard extension cords for convenience and a GFCI outlet to daisy-chain units or connect accessories such as BoiE's Ultrasonic Hydroxyl Accelerator accessory.

How It Works:
Hydroxyls are highly-reactive (radical) molecules formed naturally when UV light from the sun splits apart water molecules in the air. The resulting hydroxyl radicals instantly oxidize pollutants nearby. Hydroxyls are nature's primary method of cleaning contaminants from the atmosphere using only sunlight and water vapor. Artificially-generated hydroxyls perform the same cleansing function on indoor air and cause no harm to people, pets, plants or materials.

Odors from flooding, mold spores, cigarette smoke, fire damage, sewage spills, off gassing, body odor and decomposition are all safely broken down by a hydroxyl generator until all that remains is carbon dioxide and water.

In PCO mode (safe mode), the HYDRA PRO V2 harnesses the power of water, UV light and a catalyst to safely generate hydroxyls that neutralize odors, break down bacterial spores and pathogens, and leave nothing but fresh, clean air. PCO mode can be used with BoiE's Ultrasonic Hydroxyl Accelerator to add water vapor if the humidity in the treatment area is too low. The resulting byproducts are harmless carbon dioxide and water.

PCO hydroxyl generation, originally developed by the National Aeronautics and Space Administration (NASA) to purify air onboard a space station, is ozone-free and safe to use indoors for continuous operation in unventilated spaces with workers and other occupants present for as long as it takes to remove odors and break down contaminants.

Contaminated air is drawn through an odor-neutralizing pre-filter to trap large particulates. Next, the unit employs four germicidal (253-nm UVC) optics in a linear pattern surrounded by nano-catalyst to produce hydroxyls that break down volatile organic compounds (VOCs) and other contaminants that pass through the unit's air flow. The design uses space-saving U-shaped optics (ca. 5 linear ft.) to pack the most power possible into a compact unit.

The HYDRA PRO V2 has a powerful 500 CFM (max) axial fan that draws air through its nano-catalyst reactor. The unit has the latest PCO technology including germicidal UVC lamps rated for 9,000-hours. BoiE's unique 360-surround permanent nano-anatase TiO2 reactor grid produces the highest levels of hydroxyls possible without restricting airflow.

In AOP Mode (PCO / O3 + UV), the HYDRA PRO V2 activates a fifth optic that generates low concentration ozone. In the presence of water vapor and germicidal UV light, the ozone breaks down into hydrogen peroxide vapor (HPV), then into hydroxyls without requiring the catalyst. PCO mode continues to run simultaneously. AOP mode can be used with BoiE's Ultrasonic Hydroxyl Accelerator accessory to add water vapor to the unit's air intake if the humidity in the treatment area is too low.

In AOP mode the resulting reactions can double the unit's efficacy, increase the overall coverage area or shorten the cleaning time. Since some ozone off-gassing will exit the machine, AOP mode requires an unoccupied area or proper monitoring of ozone parts per million (PPM), especially when there is little ventilation. Ozone will revert back to normal oxygen in 30-60 minutes depending on site conditions.

The AOP used in the BoiE PRO V2 hydroxyl generator is well-studied and has been used for years in advanced water purification systems and medical sterilization systems. Below is a simplified example of the reactions that produce hydroxyls (•OH) using the HYDRA PRO V2's AOP mode:

UV Light / Ozone:
O3 + H2O + UV —› O2 + H2O2 followed by 2 O3 + H2O2 —› 2 •OH + 3 O2

Bottom Line:
PCO mode (safe mode) is most beneficial when the machine can be run for longer periods of time, with or without occupants or workers present. The PRO V2 is great to run during and after a mold remediation project to kill mold spores and to help pass mold clearance testing. The AOP Mode can increase the coverage area and decrease the cleaning time, provided that the job site is either unoccupied or is monitored for safe ozone levels.* Either mode cleans the air without causing damage to plants or sensitive materials.The built-in 500 CFM fan strikes a good balance between air changes per hour (ACH) and fan noise. When attached to an optional air mover, HYDRA PRO V2 has an expanded reach or can clean the air thoroughly during the drying process.

Like all BoiE products, the HYDRA PRO V2 was designed by professionals for professionals to exceed, outlast and outperform the competition!
