How does this effect me?
In an effort to reduce confusion surrounding safety devices for HHO systems, we have developed an internal rating system for our equipment. All our equipment is plainly labeled with this Safety Rating System (or SRS) certification. We hope that our efforts to test and rate our safety devices will help you better determine which device will best suit your individual setup.

Some background...
In our past studies, we found that a safety device may operate well within it's design specs as long as no pressure was applied during its operation. A device deemed safe after testing at a set level of HHO output could unexpectedly fail at a critical moment with the same HHO output and only a slight increase in pressure occurred. In an effort to reduce this confusion we began testing our devices with both HHO Output and Pressure in mind.

Our Safety Rating System (SRS) consists of ratings for two types of HHO Systems, On Demand Systems and Under Pressure Systems. Under this SRS a device may be given a success rating, a failure rating or both.

On Demand Systems

The HHOG Labs OD certification refers to a device that is rated for HHO systems that produce NO MORE THAN 1-PSI back pressure when in use. This is considered an On Demand system, and will receive the OD certification. Unfortunately, many of the devices (like flash Arrestors) on the market today fall under this category. For instance, compressed bronze wool Arrestors may work well, provided the HHO production is kept relatively low and the pressure remains less than 1 to 2-PSI. The danger lies in the misconception that this same device will continue to provide the same level of safety with equal amounts of HHO output even if back pressure is allowed to build. This just isn't the case.

An example of how the OD certification is applied is simple. A device that is tested and certified under the following circumstances would receive an OD rating of OD5:
1) The test was performed under NO MORE than 1-PSI
2) The test was performed with NO LESS than 5 LPM output.
This device would be considered safe under any circumstance below it's certification level.

Under Pressure Systems

The HHOG Labs UP certification refers to a device that is rated for HHO systems that produce MORE THAN 1-PSI back pressure when in use. This is considered an Under Pressure system, and will receive the UP certification. Sometimes circumstances arise when a system designer intends for pressure to play a role in his HHO setup. This is prominently found in HHO torch systems. We have found that the danger level rises exponentially with increased pressure. Any device with a UP certification is considered to have a heightened level of safety.

An example of how the UP certification is applied is a little more complex, in that a more in-depth test procedure is required. A device that is tested and certified under the following circumstances would receive an UP rating of 5UP15:
1) The test was performed under NO LESS than 5-PSI
2) The test was performed with NO LESS than 15 LPM output.
This device would be considered safe under any circumstance below it's certification level.
