The MSR Reactor range system pairs a canister range with a radiant burner head, a proprietary 1.7 L hard-anodized aluminum pot with heat-exchange fins, and a plastic lid with colander holes. It’s designed to be a near-windproof, high-efficiency cooking system for quick boiling and snow-melting in backcountry circumstances, however may also be used to simmer meals with somewhat apply. The identical range may also be used with a number of completely different pot sizes along with the 1.7L model reviewed right here, together with 1.0L and a couple of.5L reactor-specific pots.
- Weight: 17.6 oz (contains range, pot, and lid)
- Gas: Isobutane Canister w/screw-on Lindal valve
- Regulated Range: sure (guide ignition)
- Boil time: 3 to three:half-hour/liter (relying on water and air temperature)
- Means to pack 4 oz. gas canister and range head inside pot for transport.
The way it works
The Reactor makes use of a radiant burner, a flame-free warmth supply, that appears just like the floor of the solar. It’s paired with an anodized aluminum cookpot with a flat backside, heat-exchange fins, and air vents that sits immediately on the burner for superior wind resistance. Gas from a threaded isobutane canister is delivered to the burner by a precision-valved regulator and inner strain system that maintains a gentle move. The Reactor’s closed design reduces warmth loss to wind and improves gas effectivity in contrast with open burners, together with Jetboil stoves. The pot doesn’t lock to the burner meeting like a Jetboil, nevertheless, so it’s important to be very cautious to not topple the pot and spill sizzling liquid into your lap.
Boiling instances
Boil instances are impressively quick. MSR advertises about 3 minutes to boil 1 liter of water below superb circumstances. In real-world use, anticipate roughly 3-3.5 minutes for 1 liter relying on altitude and ambient temperature. The Reactor’s windproof and enclosed design makes its efficiency much more constant than typical canister stoves; in chilly or windy climate, it suffers little or no efficiency loss.
gentle it
Lighting the Reactor is simple, however guide. I take advantage of a lighter though a hearth metal additionally works.
- Connect the gas canister to the range’s valve by screwing it in till comfortable (comply with MSR’s directions and verify for leaks).
- Open the valve barely to permit fuel move.
- Use a lighter or a match to ignite the burner on the high of the range. The Reactor’s burner is enclosed, so ignite fastidiously and from the facet if wanted to succeed in the flame.
- Regulate the flame with the valve to succeed in the specified output; the built-in regulator offers a gentle flame at the same time as canister strain adjustments. Like all canister stoves, gentle it on steady, stage floor, preserve pot handles safe, and comply with the included security directions.
Snow-melting use
The Reactor is superb for melting snow. Its excessive warmth switch effectivity and regular output make it efficient at melting snow shortly and with comparatively low gas use. To keep away from scorching the cook dinner pot, break up the snow and add small quantities of liquid earlier than lighting the range. As a result of the Reactor is designed to work with upright canisters, excessive chilly can scale back canister strain, so preserve the canister heat earlier than use (retailer inside a jacket), use a gas combine with the next propane content material for higher cold-weather efficiency, or place the canister in a bowl and add sizzling water to it periodically to assist the fuel inside vaporize.
Simmering
Are you able to cook dinner with the Reactor Range? Sure, with apply and a fragile contact. Whereas the pot’s form is geared towards environment friendly boiling, the warmth exchanger makes simmering potential however requires apply to handle low fuel outputs exactly. It’s glorious for dehydrated meals, pasta, soups, and simmered stews. Frying or meals requiring a large, flat pan are much less superb as a result of the pot is deep and warmth is concentrated.
Reactor 1.7L vs JetBoil Flash 1.8
In contrast with the brand new 18.8 oz Jetboil Flash 1.8L (see the SectionHiker evaluation), the MSR Reactor 1.7L continues to be the extra weather-tolerant and versatile system, however the variations shift barely as a result of weight isn’t a transparent benefit for the Flash 1.8. The Flash delivers very quick boils and is optimized for single-pot cooking in regular circumstances, and its built-in cup/burner nesting makes it handy. Nevertheless, the Reactor handles wind and colder temperatures higher, and its cookware system presents broader floor contact for extra environment friendly heating with a wider vary of pots (1.0L and a couple of.5L, bought individually). For those who prioritize the very best efficiency in uncovered or chilly environments and need steadier output and better pot compatibility, the Reactor is the stronger alternative. For those who choose the Flash’s particular pot/burner comfort and largely cook dinner in gentle circumstances, it stays an inexpensive various, even when it doesn’t save weight, particularly since it’s so a lot cheaper than the Reactor.
Backside line
The MSR Reactor with the 1.7 L pot is a best choice for quick, wind-resistant boiling and environment friendly snow melting. It’s user-friendly to gentle and delivers constant boil instances in various circumstances, whereas additionally serving properly for a lot of one-pot cooking duties, although not for severe frying or multi-course camp cooking. It’s deal although for solo or small-group backcountry journeys the place velocity, gas effectivity, and reliability matter.
