The New, Lighter 1.0L Msr Reactor
MSR has exactly released (January, 2013), a new, lighter weight version of their Reactor stove system, with a 1.0L pot. Think of it equally a "mini Reactor" (my request it, non MSR's).
A Substantially Lighter Version
Now, I know what you're thinking, "well, of course of written report it's lighter, it's smaller."
Yes, I empathise that, but I hateful this 1 genuinely is lighter, substantially lighter, lighter than you lot would facial expression exactly based on size alone. Typically, a larger pot is genuinely lighter per unit of measurement of volume. For example, my 0.9L Primus LiTech kettle weighs 164g, which is a ratio of 0.182g/ml. My 1.5L kettle of the same build together with type weighs 219g, which is a ratio of 0.145g/ml. Yes, the larger kettle is heavier overall, but it's lighter per unit of measurement of volume.
The original Reactor pot weighs 341g (without lid), which is a ratio of 0.20g/ml. The novel Reactor pot weighs 172g, which is a ratio of 0.17g/ ml. So fifty-fifty though smaller pots usually weigh more per unit of measurement of volume, the novel Reactor genuinely weighs less per unit of measurement of volume. The weight savings hither aren't exactly from a smaller pot but rather from a redesign. Note: Both the master copy together with the novel mini Reactor role the same burner.
Update 25 March 2013: MSR informs me that at that topographic point is also a newer version of the 1.7L Reactor pot that has the same welded fins equally the novel 1.0L Reactor pot. The newer version of the 1.7L Reactor pot is lighter past times well-nigh 3 ounces ( 80g) than the master copy 1.7L Reactor pot. If you lot receive got the newer version of the 1.7L Reactor pot, your weight savings volition non live quite equally substantial if you lot switch to the 1.0L Reactor pot.
OK, so the novel Reactor is lighter than exactly what nosotros would facial expression based on the smaller pot size, how did they do it? Well, clearly MSR laid out with lightening upwards inwards mind. The oestrus exchanger, a meaning source of weight, has been revamped.
Just accept a facial expression at the higher upwards photo. The number together with thickness of the oestrus exchanger fins has been reduced. Notice also that on the master copy Reactor, the oestrus exchanger fins together with pot seem to live of 1 slice where inwards the novel mini Reactor the fins are clearly welded on. The cyberspace effect of these changes is significant: The mini Reactor is a exactly evidently lighter laid up. The mini Reactor is so much lighter that you lot abide by it correct away when you lot pick upwards the pot.
Now, MSR may human face upwards some criticism from some quarters for this pattern change. In the master copy design, the entire oestrus exchanger fin was inwards contact with the pot. In the novel design, the fin only contacts the pot at the weld. And of course of written report at that topographic point are fewer fins. Clearly, at that topographic point is going to live some reduction inwards oestrus transfer. Indeed, MSR lists the boil fourth dimension for 1 liter of H2O equally 3.0 minutes for the master copy pattern but 3.5 minutes for the novel design.
I would answer such criticism equally follows:
1. Everything inwards life is a tradeoff. In lodge to lighten things up, the oestrus exchanger had to live redesigned.
2. Entrainment of hot exhaust gasses continues undiminished (more on this inwards Appendix II).
3. The bird of oestrus transfer effected is nevertheless particular – far higher upwards that of a "plain" pot.
So, yeah, you're giving upwards some grade of efficiency, but you're gaining a much lighter system, a organisation that nevertheless plant exceptionally good at transferring heat. Beyond that, if you're genuinely worried well-nigh that lost picayune chip of oestrus transfer efficiency, together with so exactly decease out together with purchase the master copy version together with send the extra weight. MSR volition decease along to offering both versions, so accept your pick. It's the best of both worlds, really.
Update 25 March 2013: As I mentioned above, at that topographic point is a newer version of the 1.7L Reactor pot available. The newer version of the 1.7L Reactor pot nevertheless has higher efficiency than the 1.0L version. The master copy version of the 1.7L Reactor pot has been discontinued.
Now, I listed "entrainment of hot exhaust gasses" equally 1 of the things that contributes to the Reactor's amazing oestrus transfer efficiency. Just what the heck does that mean? Please encounter Appendix II, below, for an explanation.
New Features
Not only is the novel pot lighter, but they've added some novel features together with options. They're all nice, but I recall the showtime is genuinely pretty important, especially for serious climbers: MSR has come upwards out with a hanging kit.
I'll review the hanging kit separately, but for immediately permit me exactly state that the kit plant good together with that the kit is designed to tally all pot sizes for the Reactor system. Note: I've only tested the hanging kit with the 1.0L sized pot so far.
Another bang-up novel feature: They've added a pour spout. Yeah, it's exactly a picayune thing, but darn is it handy. Thank you, MSR! I for 1 appreciate MSR's attending to detail.
In conjunction with the pour spout is a novel characteristic on the lid: H5N1 drinking hole/strainer.
The knob on the lid has been changed. The novel knob tin live used to agree the lid. This may non live such a large bargain for hikers together with backpackers, but this mightiness live genuinely useful for climbers.
Now abide by also that there's a hole inwards the middle of the knob.
MSR is immediately offering a French press that fits the novel 1.0L pot. Fresh morn coffee, anyone? Nice! I'll review the java press inwards an upcoming post. Note: MSR is also offering a separate, larger French press attachment for the master copy 1.7L Reactor pot.
Packability
OK, so it's smaller together with lighter piece nevertheless beingness efficient, together with it's got some squeamish novel features together with optional extras. That's all great, but tin I nevertheless pack everything within the pot similar I could with the master copy version?
Well, equally a thing of fact, yes, you lot tin nevertheless pack everything inside. But, pay attention: Along with the novel 1.0L version of the MSR Reactor, MSR also introduced a novel canister format for their iv ounce shape canisters. The novel canister format is to a greater extent than packable together with contains essentially the same amount of gas equally their erstwhile canisters. See The New MSR Gas Canister for to a greater extent than details. You must role the novel canisters if you lot desire to pack everything within the pot.
To pack things up, showtime pose the included picayune pack stuff into the bottom of the pot. This is genuinely fairly of import for reasons that I'll explicate inwards a minute.
Then, house the canister inwards the pot upside down. Again, you lot must role the novel 3.9oz/110g MSR canisters (or a similar canister of some other brand). The erstwhile 4.0oz/113g MSR canisters volition NOT fit. Go ahead together with leave of absence the cap on the canister; at that topographic point is room.
After that, house the burner, human face upwards down, into the pot. Make sure you lot pose the valve command into the pour spout of the pot.
It's a tight fit, you lot may receive got to give it exactly a chip of a shove. Now, here's where that chip of pack stuff comes inwards handy. The halt of the valve spindle volition scratch upwards the pot.
So rather than scratch upwards your pot, simply topographic point 1 corner of your pack stuff such that it protects the pour spout, similar so:
Voila! Problem solved.
It's a tight fit, but everything does fit, together with you've got a real compact unit.
Capacity
So, the pot is billed equally a 1.0L pot, together with if you lot fill upwards the pot correct to the brim, yes you lot tin tally a liter inwards there. On the other hand, MSR recommends that you lot pose only 0.5L inwards the pot at a time. What? Only role one-half the capacity of the pot? What gives? Well, the Reactor is 1 of the most powerful backpacking stoves inwards existence. You tin instruct a vehement boil real quickly, a boil that could overtop the pot inwards the blink of the optic together with presents a real existent scalding risk. And boiling hot H2O hitting a canister? Yipes! The push clit per unit of measurement area within the canister could decease through the roof. Your stove could flare upwards or send inwards unexpected, unsafe ways. Not something I'd desire to risk!
That said, I recall a careful user, a user who kept the stove turned downwards together with watched the pot similar a hawk, could easily boil 0.75L at a fourth dimension or maybe fifty-fifty 0.8L. However, if you lot boil to a greater extent than than 0.5L at a time, you lot are going against the manufacturer's recommendations together with you lot do so at your ain risk. The consequences of a boil over could live quite severe if your canister becomes overheated. Beware!
Who the Heck Needs a Reactor?
People oftentimes inquire me: "Who the heck needs so much stove?" Indeed, who does require such a powerhouse?
Well, mayhap non mortal who is traveling inwards comparatively benign conditions. But for those who go inwards heavily windswept areas, especially mountaineers who venture into high altitude, exposed terrain, the current of air proofness of an MSR Reactor makes it exactly the stove you lot want. The Reactor is the most current of air proof upright canister stove, bar none. When other stoves neglect to fifty-fifty pick out a pot to the boil, the Reactor hums along equally though goose egg odd were happening. If I were on a barren, windswept, high height plateau, at that topographic point is no upright canister stove that I'd rather have. Indeed, it is MSR's arguing that the Reactor is the most windproof stove of all classes. I haven't yet been able to corroborate that with my land testing, but it's for sure a credible claim.
But there's some other application where the powerfulness of a Reactor tin live properly brought to bear: snowfall melting. Think well-nigh it: You push clit into your military camp for the night. You require to melt plenty snowfall for drinking together with cooking that eventide equally good equally plenty H2O for your adjacent day. You mightiness require equally many equally 6 liters. That takes a lot of time. The Reactor's powerfulness together with efficiency tin live a existent property for those who require to instruct into the pocketbook ASAP together with instruct upwards early on for an "Alpine start."
I recall thence that the Reactor volition appeal most to serious climbers together with mountaineers, but at that topographic point volition for sure live an appeal to anyone who faces meaning winds or needs to melt snowfall quickly. In it's novel compact, lighter format, the Reactor may also agree appeal to adventure racers.
Concluding Remarks
I bought an master copy Reactor several years ago. To live honest, I genuinely haven't used it all that much. Is it a bad stove? No, non at all, but I'm to a greater extent than oftentimes than non not willing to send all that weight unless I genuinely require it. If I'm non going to require to melt some serious snowfall or expecting genuinely windy conditions, I'm going to decease with something lighter. With the novel version, I facial expression to instruct a lot to a greater extent than role out of the stove.
The novel version is for sure going to appeal to soloists, especially serious climbers together with mountaineers, but a Reactor is so stinkin' fast that I recall the 1.0L pot tin nevertheless live of role to a pocket-size squad that wants to go low-cal together with fast. One exactly needs to "re-imagine" how to role the system. Instead of cooking everything at once, build pocket-size but quick courses. It would accept a chip of getting used to together with a chip of thinking through inwards advance, but the novel mini Reactor is fast plenty to arrive practical together with would allow a pocket-size squad to receive got existent weight together with infinite savings
The novel 1.0L MSR Reactor
What's adept well-nigh it?
I give thank you lot you for joining me for some other Adventure inwards Stoving,
HJ
Appendix I – Component Weights
Update 25 March 2013: I've weighed my 1.0L pot at to the lowest degree 10 times now. I instruct 172g. I talked to MSR. They weighed a pot at that topographic point inwards Seattle together with confirmed 197g. That's a divergence of 25g (nearly an ounce). I'm non sure what the number is here. My pot seems fine, but maybe I got an odd pot? If I can, I'll caput to a local shop together with encounter if I tin mensurate some other pot, but these are new, so I haven't seen them inwards whatsoever stores yet. If you lot create upwards one's remove heed to purchase one, don't count on your pot beingness 172g; it may live 197g. Regardless of the precise weight, the organisation is good designed, good pose together, together with is clearly lighter than the master copy Reactor.
Appendix II – Entrainment of Hot Exhaust
What do I hateful when I state that the Reactor "entrains hot exhaust gasses?"
Well, showtime let's accept a facial expression at the Reactor system. How does air stream through the system? Look at the exhaust vents built into the pot itself. Notice that the vents are good upwards the sides of the pot. This is important.
The hot gases produced past times combustion go out through these vents.
OK, if that's where the exhaust goes out, how does air enter the system? The burner nests tight against the bottom the pot. Air can't come upwards inwards to a greater extent than or less the sides of the burner.
So how does the air instruct in? Through the burner. Take a facial expression at a Reactor's burner. Air is entering the organisation through the air inlet holes inwards the sides of the burner (well, specifically through ii Venturi type ports on either side of the valve, but the essential thought is that the air comes inwards through the burner assembly).
OK, so we've got fresh air entering through the sides burner, proceeding through the combustion surface area of the burner, flowing along the oestrus exchanger fins, together with so upwards the sides of the pot, together with go exiting through the exhaust vents. Note that the exhaust vents are good higher upwards the bottom of the pot.
With a conventional pot, the hot exhaust from the burner exactly flows out to a greater extent than or less the bottom of the pot together with dissipates into the surrounding air. With the Reactor, the hot gasses are trapped within the oestrus exchanger assembly together with channeled along the sides of the pot. The hot gasses cannot go out until they attain the exhaust vents. These hot exhaust gasses transfer additional oestrus to the pot, heat that is unremarkably lost inwards other laid ups. The trapping of the hot output from the burner is what I hateful past times "entrainment of hot exhaust gasses" together with is something that is unique to the Reactor alongside canister stoves. This entrainment of hot exhaust gasses is business office of what gives the Reactor its real high efficiency.
Appendix III – Cold Weather together with Canister Gas Stoves
Canister stoves are to a greater extent than oftentimes than non express inwards their operational temperature attain to well-nigh 20F/-7C at ocean level towards the halt of the canister if you lot role propane/isobutane fuel (but at that topographic point are "tricks;" encounter the article list, below). I emphasize "at ocean level" hither because the higher you lot go, the colder you lot tin operate a canister stove. Generally, you lot tin operate 2 Fahrenheit degrees colder per yard feet of elevation that you lot gain (About 1 Celsius grade per 300m gain). Of course of written report with a fresh canister, you lot tin decease colder than that, but performance volition autumn off equally the canister empties. It is hard if non impossible to determine how shortly the performance volition driblet off equally the canister empties, so I recommend the practise of assuming that you lot tin decease no colder than 20F/-7C at ocean bird with propane/isobutane fuel. Note that 20F/-7C is the coldest temperature that you lot tin operate at, so don't facial expression to start at 20F/-7C together with live able to create for long with a one-half empty canister; canisters instruct colder equally you lot role them. Note also my emphasis on using a propane/isobutane fuel. You cannot role regular butane fuel inwards mutual depression temperature weather condition together with facial expression decent results. You must role a fuel that contains isobutane.
Sound complicated? Don't despair! It does accept some getting used to, but it's genuinely non also bad. For "tricks" to operating inwards mutual depression temperature weather, delight see: Cold Weather Tips for Gas Stoves
As alluded to above, it matters which build of gas you lot purchase for mutual depression temperature weather. Please see:

The novel 1.0L MSR Reactor
What's adept well-nigh it?
- Significantly lighter than the master copy 1.7L pot (and also lighter than the newer 1.7L pot, but non equally dramatically)
- Great novel options (hanging kit, java press)
- Nice novel features (pour spout, drinking holes)
- Most windproof upright canister stove known to humankind, menstruum (true of all Reactor sizes)
- Powerful snowfall melting capabilities (true of all Reactor sizes)
- Slightly less efficient (but hey, exactly decease purchase the 1.7L version if you lot genuinely require that bird of efficiency)
- Like all upright canister stoves, the Reactor is adversely affected past times mutual depression temperature weather. Assume that you lot tin decease no colder than 20F/-7C with propane/isobutane fuel unless you lot know the "tricks." See Appendix III, below, for farther information.
- The burner tin only role Reactor specific pots (true of all sizes)
