Trangia is a registered trademark of Trangia AB , a Swedish company that has been manufacturing alcohol stoves since 1925 . The company's headquarters are in Trångsviken in the municipality of Krokom in the province of Jämtlands län .
Company history
Trangia was founded in 1925 by John E. Jonsson and his father-in-law. The company was a leader in the manufacture of storm-resistant cooking appliances in Sweden for more than half a century.
The company gained fame above all for the Trangia stove, an outdoor spirit stove that has been manufactured since 1950. The cooker set produced in Sweden made Trangia one of the most successful cooker manufacturers on the market.
Trangia is distributed outside of Sweden through twenty license dealers worldwide. The license dealers are located in Australia, Denmark, Germany, France, Finland, Estonia, Great Britain, Ireland, Hong Kong, Holland, Israel, Italy, Japan, Latvia, New Zealand, Norway, Switzerland, Spain, Turkey, the Czech Republic and the USA .
Products
Trangia products are mainly aimed at hikers , especially friends of the "light-weight" movement. Trangia stoves are characterized by a long service life and are designed with a simple design.
Trangia burner
The patented Trangia burner forms the heart of the storm cooker. The three-component burner is made of brass . It is provided with a screw cap with a rubber sealing ring and the so-called sparring (a well-closing regulation ring), which can also be used as an extinguisher. The burner is similar to a rechaud , but also has an inner cylinder that almost reaches the bottom. When filling, fuel also gets into the cavity between the inner and outer cylinder, which is provided with 23 or 24 small nozzles on the top. At least newer specimens seem to have a kind of “wick” that lies between the cylinders and extends all the way to the nozzles.
The functional principle:
- The fuel that was poured into the inner cylinder (center) before igniting will burn there first. At temperatures below 10 ° C ( flash point of ethanol 13 ° C) it can be difficult or even impossible to ignite the burner; it must then be preheated (see below).
- The flames in the inner cylinder heat the inner sheet metal jacket until the fuel boils in the cavity between the cylinders. The duration of this heating phase depends on the outside temperature, wind strength and level.
- The spirit that then escapes in gaseous form from the nozzles ignites and burns there comparatively efficiently. The construction has no moving parts and is therefore very reliable.
By putting on the sparring and with the sliding cover attached to the sparring, it is possible to regulate the flame. If the cover is closed completely, the flame extinguishes completely in the absence of air.
If you close the burner with the screw cap, fuel can be carried in the burner. The rubber seal prevents the fuel from leaking. The screw cap is protected against inadvertent unscrewing by the sparring that is pushed over and pressed into place. The escape of vapors is prevented by a tear-resistant polyethylene (low density) protective bag. A plastic bag is also important for transport in order to prevent a short circuit and thus corrosion between the materials used, brass and aluminum. Before closing, the burner should be allowed to cool down, otherwise negative pressure will develop, which will make the next opening difficult. Should this happen, the gripper pliers supplied with the system can be pushed with the back under the edge of the lid and air can be let into the burner with a careful turn. The cover can then be unscrewed as usual.
For operation at low temperatures, a so-called preheating claw is available, which is clamped under the burner and has a hollow with a wick-like glass fiber fabric at the bottom. A few drops of alcohol can be easily ignited there and then heat the fuel in the burner beyond the fire point . It is also possible to carry the burner filled with alcohol with you until you use it on your body (trouser pocket, etc.) in order to keep the fuel at an ignitable temperature. There is no risk of alcohol escaping if the burner is correctly closed.
The Trangia burner has an impressive performance for an alcohol burner: 50 milliliters of denatured alcohol boil one liter of water within 10 to 15 minutes, which corresponds to a net output of around 300 watts. One filling of the alcohol burner is enough for a burning time of around 25 minutes.
Trangia system
The system consists of a draft shield, two pots, a frying pan that doubles as a lid, a kettle (not on all models) and the actual burner. There are also grip pliers and a packing strap, which enables quiet transport in hiking luggage. All individual parts can be stowed together for transport to save space. To protect against dirt and damage, the cooker set can be stored in a perfectly fitting orange packing bag with a drawstring.
The standard cooker sets are available in four series with up to eight models:
- Series 27 , suitable for 1–2 people
- Series 25 , suitable for 3–4 people
- Series 35 , identical to series 25, but entirely in black
- Mini Trangia , (sometimes referred to as Series 28 ), suitable for one person; only includes a burner, a base frame, a 0.7 liter pot (aluminum), a lid or pan (non-stick aluminum) and a pair of tongs.
materials
The aluminum series, previously marketed as a standard version, were replaced in 2007 by the stoves made of "Ultralight Aluminum", an alloy that, according to the manufacturer, is harder and therefore allows the use of lower material thicknesses. According to Trangia, this reduces the weight of the stove by 22-25%. The "Ultralight Hardanodized Aluminum" version, which is also available, consists of the same material, but which has been given an extremely hard and scratch-resistant surface finish through hard anodization . This is also characterized by easier cleaning and less pronounced sticking in the frying pan. It replaces the titanium versions that are no longer produced (particularly light). All series are optionally available with a non-stick frying pan. Since January 2018, Duossal, a laminate made of stainless steel (food-safe and scratch-resistant) and aluminum (very good thermal conductivity), has been available again in the Trangia range.
Alternative lighting
In addition to the alcohol burner, burners for other fuels such as petrol , kerosene , gas or solid fuels can also be used in the windshield of the system .
