The new aobaosi.tech: from the right spear to safe removal
We have rebuilt our website from the ground up. It is designed to make daily work easier for buyers, breweries and workshops: finding the right spear, determining the right length and removing and installing spears safely.
Anyone ordering a keg spear usually has very specific questions. Which system do my kegs use? How long does the spear have to be? Which coupler fits? And how do I remove the spear without anyone getting hurt? The old website showed our products but hardly answered these questions. The new one does exactly that.
It is based on the documents our plant works with: the STEP files of the spears, the assembly drawings, the manuals and the test certificates. Everything on the site can be traced back to these sources.
Finding the right spear
Each of the five systems A, S, D, G and M has its own product page with the same structure: a 3D view that breaks down into its components with a slider, a top view, technical data, an assembly drawing with parts list and the matching documents. This makes it easy to compare the types.
The compatibility table shows which spear fits which keg neck, keg and coupler. On top of that there are 32 keg couplers for all five systems and our stainless steel 304 keg necks with 2″–14 TPI thread to BS 84.
The right length, in seconds
A spear that is too long sits on the sump, one that is too short leaves beer behind in every keg. From the keg’s H3 dimension the calculator works out the overall length TL, which is used for ordering, and the length to the seal SL. For DIN, Euro and Slim kegs, or with your own dimension.
What a wrong length does inside the keg is shown by the 3D simulator “Keg in cross-section”: cleaning and dispensing with a correct, too long and too short down tube, for all systems.
Working safely on the spear
A spear is under pressure. That is why five animations, created directly from our STEP data, show every step: venting, removing and installing type A, removing and installing type S. Plus the right tools, the tightening torque of 80 ± 5 Nm, retightening empty returned kegs to 60 Nm and the note that the body seal is replaced every time the spear is removed.
If something is still wrong, the troubleshooting guide helps to find the cause. Spare parts are listed with article numbers, and the glossary explains every technical term with its German, Dutch and French equivalent.
Everything documented, in six languages
The download area contains the DGUV Test certificates with SK marking, ISO 9001 and FSSC 22000, the test reports from SGS and Intertek, and manuals and product sheets, each with its validity.
The website is fully available in German, English, Dutch, French, Spanish and Portuguese. It detects the browser language, and the language selector is at the top right of every page. Fonts and 3D libraries are hosted on our own server.
