are limited due to Covid-19 high demand
The BoiE HYDRA PRO
XL is the ultimate, multipurpose hydroxyl generator for challenging restoration projects including mold and sewage
remediation, water and fire damage restoration, and dust and odor control. The BoiE HYDRA PRO XL will break apart
odors from fire and smoke, category 2 & 3 water losses, chemical fumes, fuel oil and VOCs.
Designed for restoration service companies, the HYDRA PRO XL's combination of features make it unlike any other
hydroxyl generator on the market today. The unit combines the benefits of a portable HEPA air scrubber and a versatile
hydroxyl generator with four modes of operation, making the HYDRA PRO XL a unique solution for indoor air purification
or mold remediation projects.
The HYDRA PRO XL can be used in PhotoCatalytic Oxidation (PCO) mode with occupants present, or in Advanced Oxidation
Process (AOP) modes with monitoring and appropriate PPE when workers are present.* Both types of operation are
safe for plants and sensitive materials.
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 occupants or materials.
The HYDRA PRO XL attacks and instantly kills bacteria and viruses including corona-type viruses¹ but is completely
safe to operate continuously. A recent study shows that the novel coronavirus COVID-19 can circulate in the air
for up to three hours.² UV light alone will not destroy viruses circulating in the air because it takes 5-10
seconds of direct exposure to contaminants at close proximity to be effective. Air purifiers with HEPA filters
cannot trap something as small as a virus (.004 to 0.1 microns). For coronavirus safety at the jobsite, purchase
a HYDRA PRO XL hydroxyl generator, and wash your hands often.
Odors from flooding, mold spores, cigarette smoke, fire damage, sewage spills, off gassing, bacteria, body odor,
decomposition and airborne viruses are all safely broken down by a hydroxyl generator until all that remains is
carbon dioxide and water.
Since hydroxyls result from water vapor, any meaningful amount of hydroxyl generation requires significant relative
humidity in the air. The HYDRA PRO XL solves the low-humidity problem by generating and transferring water vapor
to a direct injection manifold inside the machine that evenly distributes the vapor over the optics to maximize
In addition to safe PCO mode, the HYDRA PRO XL's three AOP modes can double or triple hydroxyl production. These
options include low concentration Hydrogen Peroxide Vapor (HPV), low concentration UV Ozone (O3/UV) and a combination
In PCO mode (Safe Mode), the HYDRA PRO XL 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 or without the included water vapor injection system, depending on site conditions.
The resulting byproducts are harmless carbon dioxide and water.
PCO hydroxyl generation, originally developed by NASA, is ozone-free and safe to use indoors for continuous operation
in unventilated spaces for as long as it takes to remove odors and break down contaminants.
Contaminated air is drawn through an odor-neutralizing pre-filter and a HEPA filter to trap most particulates.
Next, the unit employs six germicidal (253-nm UVC) optics in a 2-layer crosshatch pattern along with 3 layers of
nano-catalyst to produce hydroxyls that break down volatile organic compounds (VOCs) and other contaminants that
pass through the unit's air flow. The machine's high static pressure centrifugal fan runs quietly, making it a
good choice for occupied areas such as a client's home.
In AOP Mode 1 (PCO / HPV + UV), hydrogen peroxide is used in the ULTRA's ultrasonic direct injection system
instead of pure water. The resulting low-concentration hydrogen peroxide vapor (HPV) vapor breaks down into hydroxyls
when exposed to the unit's germicidal UV light without requiring the catalyst. To initiate AOP Mode 1, you simply
add a commercially-available hydrogen peroxide solution to the unit's direct injection reservoir and run the Advance
in PCO mode. PhotoCatalytic reactions on the catalyst will occur simultaneously. No ozone is generated in Safe
Mode, however, HPV levels in the air must be monitored if workers are present. This AOP is the simplest method
to generate hydroxyls using UV light. Below is a simplified equation for this AOP where two hydroxyl radicals are
created from each hydrogen peroxide molecule:
Hydrogen Peroxide / UV Light:
H2O2 + UV 2 OH
In AOP Mode 2 (PCO / O3 + UV), the HYDRA PRO XL activates a seventh 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. The ULTRA's
ultrasonic direct injection system can be used to add water vapor if the humidity in the treatment area is too
low. Ozone levels in the air must be monitored if workers are present. Below is a simplified equation of this AOP:
In AOP Mode 3 (PCO / HPV + O3 + UV), the HYDRA PRO XL combines hydrogen peroxide vapor (refer to AOP Mode
1) and low concentration ozone (refer to AOP Mode 2). PCO mode continues to run simultaneously. As the ozone and
HPV form hydroxyls, the UV light exposure causes more direct and indirect oxidation reactions to occur. The result
is a greater conversion of intermediate reactants into hydroxyls (OH), e.g. more cleaning power. HPV and O3 levels
in the air must be monitored if workers are present.
In AOP modes the resulting reactions can double the unit's efficacy, increase the overall coverage area or shorten
the cleaning time. Since some ozone and/or hydrogen peroxide vapor off-gassing will occur, AOP modes require an
unoccupied area or proper worker protection, especially when there is little ventilation. Ozone and hydrogen peroxide
off-gas will each break down naturally into oxygen and oxygen/water, respectively, after a few hours.
All advanced oxidation processes used in the BoiE Advance hydroxyl generator are well-studied and have been used
for years in advanced water purification systems and medical sterilization equipment.
The standard PCO mode is most beneficial when the machine can be run for longer periods of time, with or without
occupants or workers present. The advanced oxidation process modes can increase the coverage area and decrease
the cleaning time, provided that the job site is either unoccupied or is monitored for worker safety.* Both modes
clean the air without causing damage to plants or sensitive materials. The HYDRA PRO XL includes a direct injection
version of BoiE's Ultrasonic Hydroxyl Accelerator accessory that turbocharges
the airflow with moisture to maximize hydroxyl production in dry conditions.
Like all BoiE products, the HYDRA PRO XL was designed by professionals for professionals to exceed, outlast
and outperform the competition!
