SpecAir started it all.
Right now Portagas and Gasco are the reusable portable cylinder kings right behind the giant Calgaz which company dominates the world of portable cylinders like a colossus. Calgaz, has, as they say, the money keep that profile for a while to come.
While the debate continues as to whether disposable portable cylinders or re-fillable portable cylinders has the better carbon footprint (kind of like discussing organic foods in a room half full of vegetarians and half full of barbecue black belts) it's interesting to ignore the zealots and take a look at the company that really broke in the ideas. In this case, it all unfolded at a company named SpecAir- they did it first.
SpecAir came out with refillable portable cylinders with the same CGA valve interface that disposable cylinders were using- they did this over thirty years ago and Called their product Enviro-Cyl. They took the lead and kept going before the other disposable calibration gas companies even considered the idea.
Here's how they describe their offering:
The SpecAir Speciality Gases product line offers a refillable, portable calibration gas cylinder as an alternative to standard disposable cylinders. The Enviro-Cyl product calibration gas cylinder offers many advantages over disposables. They are:
• Portable, light weight and refillable aluminum cylinders
• Economical 50-100% more capacity than disposables
• No cylinders to dispose of...simply return for refill
• Eliminates disposal fees and regulatory paperwork
• No more problems with landfills or recycling
• Cost efficient; no deposits or rental fees
Enviro-Cyl cylinders all come with a brass or stainless steel valve, safety on cylinder valve, and a 5 year DOT stamp.
Nice idea when they came out with it. Still a great idea pushed by a great company.
Hats off to SpecAir.
