為了百份百確保品質，每個爐子在發貨前都經過明火測試。如果它造”大”了，火焰會燃燒出綠色，如果燃油不足，則趨向黃色。只有剛好正確 - 精準的 0.37mm (如果你想知道) - 火焰會處於最佳的橙色。
That up there is a drill so fine that the gas jet on the left spins rather than the drill-bit. The point is that for Swedish stove specialist Primus, precision matters. Make the hole just microscopically too large and the flame will burn slightly too rich wasting precious fuel, make it too small and it won’t burn hot enough. Just one hundredth of a mm can make a difference.
And to make sure nothing’s left to chance, each stove is test-fired before being shipped. If it’s oversized, the flame burns green, if it’s under-fuelled, it tends towards yellow. Get it just right – 0.37mm if you were wondering – and the flame is an optimal orange.
這有什麼關係？最佳的燃油效率意味著最好的功率水平，對於 LITE+ 爐具所針對的輕量級背包客來說，效率最高。或者換句話說，每罐燃氣可享受更多杯的茶。
Why does it matter? Optimal fuelling means both the best level of power and, just importantly for the lightweight backpackers the LITE+ is aimed at, the best possible efficiency. Or, to put it another way, more mugs of tea per gas canister.
可以說，Primus 一直至今都在製造爐具。在1892年品牌推出第一個國內用的 soot-free kerosene 無菸煤油爐（paraffin 石蠟），已超過100年，公司的工廠一直在瑞典斯德哥爾摩。
多年來，這個品牌從原來的家用爐灶市場轉移到了一般的野營產品，然後進入更專業的戶外裝備應用。Primus具有真正歷史遺產，不少探險/登山界猛人如 Hillary 及 Tenzing (1953年新西蘭探險家／登山家Edmund Hillary及尼泊爾Sherpa雪巴人Tenzing Norgay 成為首批登上 Mt. Everest登山者)，挪威極地探險家 Roald Amundsen( 於1911年Roald領導的探險隊為第一支到達南極的探險隊 ）和 瑞典探險家及登山家 Göran Kropp (1966年 Göran 以無氧氣筒及Sherpa協助下獨自攀登 Mt. Everest）等等都是用 Primus 爐具烹茶煮食。
而且英國不少年輕的戶外人也用過Primus的經典的黃銅石蠟火爐 - 市場上另一個爐具品牌是Optimus，是瑞士品牌。現在最新的Primus爐具套件，已銷往世界各地50多個國家，當中包括出了名嚴格管制的日本市場，在那裹嚴酷的測試意味著一些競爭對手不敢涉足...
Over the years the brand’s moved from its original domestic stove market, first into general camping and then into more specialist outdoor applications. It has genuine heritage with the likes of Hillary and Tenzing, Roald Amundsen and Goran Kropp having cooked their tea on Primus stoves.
And a fair number of young Brits cut their outdoor teeth on the brand’s classic brass paraffin burners too – the other big name in the market, Optimus, by the way, is Swiss owned. These days Primus stoves are cutting edge kit and sold in more than 50 countries around the world including the notoriously strictly regulated Japanese market, where draconian testing means some rivals fear to tread…
In other words, Primus has been around for longer than most, but one thing comes over loud and clear. It’s certainly not resting on its laurels. The brand’s Stockholm HQ is in an unremarkable modern office building in Stockholm, but tucked away in the basement is the top secret research and development facility known as ‘The Basement’.
Think of it as where Primus’s very own Q and his development team work on future projects and you won’t go far wrong. Tucked away behind an unremarkable industrial door in the corner of the building’s basement car park, it’s a delightfully random mix of the past and the present, traditional and modern, analogue and digital.

That's what we call a drill... precision industrial machinery from the last century was saved from the original factory and is still going strong... image: Jon
Meet ‘Q’… Or Should That Be ‘P’?
Primus地下室有種很超現實的感覺。看看這個1962年由伊利諾伊州 Des Plaines 的 DoALL 公司製造的精密銑床或德國慕尼黑 Friedrich Deckel 生產的大規模工業鑽機。 如果這些機械可以說話一定很有趣...
There’s something of the surreal about the Primus basement. Check out the precision milling machine made in 1962 by the DoALL Company of Des Plaines, Illinois or the massive industrial drill produced by Friedrich Deckel of Munich. If machinery could talk…
所有設計也經過現場測試，在生產前 prototypes 原模型都會在惡劣的環境中實地使用，由概念之始以至設計過程對測試的關注令人印象深刻。
Designs are field tested too with prototypes being used in hostile environments before production is finalised, but the attention that goes into the initial design process is impressively thorough.
A little sadly those vintage but still functioning machines are all that’s left of the original Primus factory in Stockholm, but the brand’s stoves are still made, or more accurately ‘assembled’ in Europe, just across the Baltic in Estonia.
It’s there that a workforce of 22 skilled operators methodically piece together precision-made stove components from the far east to create around 400 stoves per day and some 200,000 units a year including lanterns.
Each stove takes approximately five minutes to assemble, with different stations tackling each stage of the assembly work. It’s an impressive operation, not so much in terms of the heritage or amazing machinery, more that unrelenting precision and attention to detail that culminates in every single Primus stove being hand tested before it leaves the factory. Impressive.
To get you in the industrial mood, here are a few snaps of the factory, more about the assembly process in a moment.
看似是 Primus 估算中但輕率的一個決定，我們居然被允許組裝自己的 LITE+ 爐頭，這是品牌把煮食系統cooking system 加入個人化的新選項。目的是樣人了解整個過程是如何組裝成，讓人驚嘆於Primus團隊的靈巧性，他們比我們更有能力。
爐頭的核心是我們進來時的精密鑽機。每個單獨加工至精確度為0.37mm，準確度為+或 - 0.01mm。 鑽機嘴太幼細，變成噴嘴組件旋轉而不是鑽頭。 這是個令人印象深刻的過程，是爐頭能正確地燃燒的關鍵。
In a move of calculated recklessness by Primus, we were allowed to assemble our own LITE+ stove, the brand’s updated personal cooking system option. The idea was to get an idea of how things go together and allow is to marvel at the dexterity of the Primus workforce who were somewhat more capable than us…
The heart of the stove is that precision drilled jet we came in on. Each is machined individually to an exact 0.37mm with a precision of + or – 0.01mm. The drill is so thin that the jet spins rather than the bit. It’s an impressive process, that’s crucial to the correct burning of the stove.
Next the multiple parts that make the slot-on burner unit are bolted together with a mechanical wrench before the gas connector and jet are screwed into place. It’s like a sophisticated Meccano set, but with better tool and greater precision.
You’ll be glad to know there’s a hammer involved too, or at least a soft-faced mallet. You can’t make anything worthwhile without a hammer…
Next the screw-on valve / and piezo electric unit plus burner are added, again with the aid of a powered driver leaving the bulk of the burner unit complete and ready to go.
最後，固定線安裝在鍋架上，下一部是到熱轉換器ETA鍋側的配件。 這很簡單，只是添加隔熱鍋套和三個螺絲鍋手把的問題，再加上一個“Exploration Ready” 吊牌來說明爐子已被測試過…
At this point, the burner unit is hooked up to an internal gas supply – no canisters harmed – and test fired to make sure that the piezo unit works and the flame is burning at just the right colour to show that the jet is within tolerance.
Finally a retainer wire is fitted to the pot holding plate and it’s time to move onto the heat exchanger ETA pot side of things. This is simple, just a question of adding the insulated sleeve and the three screw-in pot supports, an Exploration Ready tag is added to explain that the stove has been test-fired…
Finally the stove’s are boxed up and ready to roll in search of a thousand adventures – or something like that. Except for this one, produced personally by Primus UK’s Andy Brown and destined to return to the UK with him. Or rather with me. Rather slowly, sorry about that Andy…
除了工廠真的視覺上很酷的地方，請看看下面的圖片畫廊 - 製作頂級規格的戶外爐灶都是關於沒完沒了的小配件。令我們印象深刻的是在斯德哥爾摩R&D研發部門地下室和愛沙尼亞工廠看到對細節度堅韌不懈的專注。
我們喜愛Primus花時間來明火測試每一個製造的爐灶，以確保它在離開工廠之前如常運作。 而且我們喜愛品牌心思細密的設計 - 我們認為這是整潔爐灶整合的王國，伴隨著自身悠久傳統的意識。
有些人可能會認為這些爐具現今並不在瑞典生產很遺憾，但其實 Primus 的重點是不論原產地而採購最好的組件，在愛沙尼亞“製造”中的爐頭，事前均由Primus採購來自於全世界各地最精密的零件，再由熟練的技術人員結合及組裝成最終的完成品。
Apart from factories being really cool places visually – check out the gallery below – making top spec outdoor stoves is all about getting the small things bang on. We were properly impressed by the relentless attention to detail both at the Stockholm R&B basement and in the Estonian factory.
We love that Primus takes the time to test fire every single stove that it manufactures to make sure it works as it should before it leaves the factory. And we love the brand’s thoughtful design – we reckon it’s the king of neat stove integration – along with its awareness of its own heritage.
Some might think that it’s a shame that the stoves aren’t produced in Sweden these days, but Primus are all about sourcing the best components regardless of origin, and while the stoves are ‘made’ in Estonia, Primus sources precision parts are sourced all over the world before being united and assembled by the skilled workforce into the finished product.
最後，工廠所在的 Tartu 塔爾圖是一個很酷，非常友好的城市，擁有一個比你預期的更華麗和更大的大學中心。
Speaking of which bolting together stoves isn’t quite as easy as you might think, particularly at any sort of speed, just saying…
Finally, Tartu, where the factory is based, is a very cool, very friendly city complete with a university centre that’s rather grander and larger than you’d expect.
