Take your beer on the go and leave the glass at home! These large 32 oz crowlers are a great replacement for heavy, fragile glass growlers. Fully compatible with the Cannular Pro Can Seamer when used with the Chuck Adapter for Ball 300 Ends.

Aluminum cans offer 100% protection from UV and other wavelengths of light that are harmful to beer. There’s still great debate surrounding whether cans or bottles are better at keeping beer fresh, but if done correctly, cans are theoretically the superior option. When a crown cap is crimped onto a bottle, the lining of the cap can form an imperfect seal on the bottle, allowing small amounts of oxygen in, as well as small amounts of CO2 out. Over time this can result in oxidation of the beer and lost carbonation. Seamed cans form a much better seal, which can prevent these issues

Aside from better protection, aluminum cans are undoubtedly the safest option for sharing and enjoying your homebrew. Bring your canned creations tailgating, camping, boating, or crack a few open poolside without the worry of broken glass!

To use these cans with the Cannular Pro Can Seamer you will also need the CAN112 chuck adapter.

32 oz / 946 mL aluminum crowlers
Each case contains 149 cans and lids
300/307 x 710 Crowler
One case is enough for roughly seven 5-gallon batches of beer
Compatible with the Cannular Pro Can Seamer when used with Ball 300 Chuck Adapter (CAN112)
Water-based polymer interior coating
Please note that empty aluminum cans are very delicate, and up to 5% of the cans are likely to be dented or damaged in transit. If the cans were packed in a more protective (more expensive) cardboard box, the cost per can would be more expensive than simply having some dented/sacrificial cans arrive.

The Cannular Pro is a semi-automatic can seamer that is easy to use, reliable, and beautifully simple.

Whether you’re a brewery looking to offer canned beer to go or a homebrewer wanting to keep your creations fresh and fully protected from light, the Cannular is the answer. This bench top unit is one of the most compact and easy to use can seamers you’ll find. The Cannular only requires one person to operate, and each can takes roughly 3 seconds to seam. With a two-person team, one filling and one seaming, the Cannular becomes a suitable option for nano breweries doing small canning production runs.

Cannular Pro vs. Manual Unit
This new Semi-Auto Pro model will guarantee you get a consistent seaming process every time. Unlike the less expensive manual can seamer, this machine has no lever for the seaming operation, meaning it’s even easier for the operator to seam the can consistently and will not vary on how hard the operator is pulling the lever.

Another major difference is that the Cannular’s Pro table spacer is specially designed to work with both 500ml (16.9 oz) and 330ml (11.2 oz) Can Fresh Aluminum Cans right out of the box. Unlike the manual model that requires a secondary table spacer for use with 330ml cans, the Pro model features an adjustable platform, allowing you to raise or lower the table spacer depending on what size can you’re seaming. We have tested standard 202 cans and have been able to achieve good seals with proper adjustments. It is necessary to adjust the table height to ensure you have the appropriate amount of pressure applied when the can lift is raised.

Operation:
The beauty of the Cannular lies in how truly simple it is to operate, and the semi-automatic pro model makes canning beer even easier. With only three points of operation, it only takes a few minutes to familiarize yourself with the machine. The seaming process is as follows:

• Place lid atop the can and place the can on the table spacer
• Turn the platform lever clockwise to raise the can to the seamer
• Press the seaming operation button then wait for the can to stop spinning
• Turn the platform lever counterclockwise to lower the can
• That’s all there is to it!

Construction:
The Cannular was designed to be compact, durable, and safe to operate in a wet environment. The platform assembly is made from 304 grade stainless steel, so no matter how messy your canning gets, there’s no need to worry about rusting or degradation. The body of the unit is made from hammered sheet metal and fastened together with stainless steel screws. Rubber feet help keep the unit from slipping and sliding while in use. In addition, the Cannular features built-in brackets near the feet so you have the option to mount the machine to your counter or benchtop. The Cannular runs off of 24V DC power via the Anderson socket located on the back. This lower voltage was chosen specifically to make the unit as safe to use in a wet environment as possible.

Power:
As noted above, the Cannular comes with a 24V DC Anderson socket located on the back of the unit. It does not, however, include a cord and plug. When purchasing the unit, you have the option of pairing it with either a power supply with 110V plug (CAN101), or with a 6 ft. long cord with Anderson plug and alligator clips (CAN102). The power supply is straight forward, and allows you to plug the unit into a standard 110V power socket. The alligator clips give you the option to power the unit from a battery, and can even be used with an 18V cordless power drill battery. This is certainly the most affordable option for powering the Cannular, and we’ve found that upwards of 200 cans can be seamed on a single battery charge.

Why Cans?
So why can when you can bottle? There’s no doubt that canning has become a more and more popular format for packaging beer among craft breweries over the last several years, and with good reason. Aluminum cans aren’t just more environmentally friendly than bottles, since cans require less energy to transport and recycle, they’re also much better at protecting the quality of the beer. Whereas bottles allow in light, which leads to skunking, aluminum cans offer 100% protection from UV and other wavelengths of light that are harmful to beer. There’s still great debate surrounding whether cans or bottles are better at keeping beer fresh, but if done correctly, cans are theoretically the superior option. When a crown cap is crimped onto a bottle, the lining of the cap can form an imperfect seal on the bottle, allowing small amounts of oxygen in, as well as small amounts of CO2 out. Over time this can result in oxidation of the beer and lost carbonation. Seamed cans, on the other hand, form a much better seal that can prevent these issues. Of course, it’s important to make sure that the can is purged of oxygen before being filled, and that the can lid is sealed atop foam to eliminate oxygen from the headspace. Aside from all the “sciency stuff”, cans are just plain safer. Take your beer backpacking, camping, or poolside and rest assured that broken glass won’t ruin your day!

Please note: When you receive your cannular the rollers have been set and tested at the factory. They should not need adjustment for 100,000 cans. The table, however, comes unadjusted and getting it set up correctly is very important to getting a proper seal. Cannular’s test show that a .4mm (.015″) actual overlap is all that is needed to seal to 90 PSI. The proper table tension takes a little practice and expect to waste a few cans getting it dialed in. Once you learn the proper tension re-adjusting it is very quick and easy. You want the tension to be tight but not so tight as to dent the can. Use cans at your fill height with water for proper tension adjustment.
