Top 5 Signs That You Should Service or Replace Your Gas Generator

The alarms for leak detection are either not going off when there is a leak or are constantly going off even when there are no leaks.
You are moving into new applications and your current gas generator does not produce the gas or gases you need or isn’t sized right for the systems you need to generate gas for.
The air filter in the zero-air gas generator is clogged.
The noise from the gas generator’s integrated compressor is too loud.
Your current gas generator doesn’t have all the features you need, such as the ability to capture performance data ,etc.

Maintenance Tips: For certain hydrogen gas generators, vendors recommend charging the device with deionized water and replacing an ion exchange “scrubber” every six months. For zero-air gas generators, the air filter should be replaced once a year.

Top 6 Questions That You Should Ask When Buying a Gas Generator

What application do you need a supply of gas for? Depending on the experiment or application you may need one or more hydrogen, nitrogen or a zero-air gas generators.
How many systems will your gas generator supply? There are a number of sizes of gas generator that will service one or many systems for a number of applications
If you need to supply gas to more than one system, are you planning on having a central source of gas? The number of labs you need to supply will determine whether you opt for a larger, central generator or numerous, smaller generators.
Is space an issue in your lab? It may be that you need a smaller, standalone generator that can be stored or stacked away to save space.
What are the safety parameters that you must adhere to when using gases? A generator significantly reduces the hazardous risk that comes with on-site gas supplies, but it’s good to discuss your gas options with your safety representative.
What service proposition comes with the gas generator? There are a number of options when managing a generator, whether that’s getting an education in self-maintenance, knowing a service representative will be able to maintain the unit regularly or having the ability to send a unit back to the manufacturer.
