What preventative maintenance should I be performing on my generator?

Preventative maintenance is critical to ensuring that your generator operates reliably throughout it's lifetime. A maintenance table which includes the recommended preventative maintenance schedule for your generator can be found in the back of the user or maintenance manual for your generator. if you require a copy of your generator's manual, please send a request to techsupport@protononsite.com and include your generator serial number. 

What water quality do I need?

The water needs to be Deionized and is required at minimum ASTM Type II (>1 MegOhm-cm) or recommended at ASTM Type I (>10 MegOhm-cm).  Water quality should also be measured in Total Silica, Total Organics, and Total Carbon for proper application assessment.   


Do I need a DI water system?

All Proton hydrogen generators require DI Water to properly operate.  If it is not readily available, Proton can provide an appropriate water system to accommodate the hydrogen generator(s).


Why switch from helium to hydrogen?

Laboratory practitioners need a carrier gas they can count on. But helium – traditionally used as a gas chromatography (GC) carrier gas – supplies are dwindling, forcing laboratories to pay more and accept a higher risk of supply. Laboratories are increasingly looking for a more reliable and less expensive solution than helium gas. The only carrier gas that can offer higher reliability and lower cost – plus faster results – is hydrogen, made on-site. A PEM electrolysis hydrogen generator safely and reliably produces a limitless supply of ultra-pure hydrogen at a fraction of the cost of delivered helium. 

What is PSA?

PSA (Pressure swing adsorption) technology separates nitrogen molecules from the other gas molecules by the carbon molecular sieves (CMS). Alternating between both CMS columns, firstly O2, moisture, hydrocarbons, CO2, and other “contaminants” are absorbed, allowing the nitrogen to flow into an accumulation tank. From the accumulation tank the nitrogen is pressurized and delivered to the generator outlet for use.

Energy Storage

Are on-site gas generators sustainable/green?

At Proton Onsite,  Yes.  In comparison to other hydrogen-generating electrolysis technology, there is no KOH required to operate Proton's generators. Also, there is no CO2 byproducts in the production of our hydrogen.  Our process consists of splitting hydrogen and oxygen via PEM electrolysis.
