Specialty Gas Distribution Equipment for Springfield

Specialty gases really aren’t any more usable than the devices tasked to distribute them. The purity and precision these gases offer may well be diluted without adequate pressure and flow control and without the provisions to corroborate gas use.

While the general consensus is that compressed gases, by virtue of their prevalent characteristics,should be delivered in high-pressure gas cylinders, regulating that pressure in typical use is frequently treated as a matter of secondary importance. There are major distinctions between cylinder regulators created for oxy-fuel cutting and welding, typical purge gas applications, and specialty gas use.

The PurityPlus® gas pressure-reducing regulators and flowmeters available from ILMO Products Company give you a level of quality in materials, design, and assembly that distinguishes them from standard industrial gas equipment. Though costing more, this equipment generally provides a value that far exceeds its price. PurityPlus® regulators, for instance, generally have diaphragms made of stainless steel, not rubber. Rubber diaphragms tend to absorb moisture and impurities, then off-gas these contaminants as the cylinder supply pressure dips. This can have a negative effect on carrier gas flow and instrument response.

Just as disconcerting is the matter of crawl. As the pressure in a gas cylinder is lowered, the pressure on the diaphragm is also reduced, and the outlet pressure can increase. To offset this action and tamp down its effects, it is heartily recommended that a two-stage PurityPlus® regulator be applied. The manufacturer presets the first-stage pressure reduction, generally around 300-500 psig, while the user is allowed to  control the final outlet pressure in the second stage. Setting an intermediate pressure reduces the crawl effect by the second stage so  it’s pretty much gone until the cylinder pressure falls below 150-200 psig.

Compare this to an industrial gas single-stage regulator. As a result of the single-stage design, the single diaphragm sees a unbroken lessening of supply pressure as well as an unhurried but uninterrupted rise in outlet pressure that can vary as much as 10-15 psig.

These are only a couple of examples showing why the right gas also requires the right gas equipment. Contact us online or call us, ILMO Products Company, at (217) 245-2183.
