STOVE TECH: A LEGACY OF INNOVATION

Every MSR ® stove ever built has come to fruition with a singular purpose—to solve real word problems. Our forward-thinking innovations have led the industry and broken down barriers to what could be accomplished outdoors. Whether your goal is reaching the world’s farthest corners or laying out a feast for friends on a weekend close to home, you can trust MSR to lead the way.

Problem: High Altitude Dehydration

MSR Innovation: Remote Burner Stoves

Introduced in 1973, the Model 9 stove was the first to separate burner and fuel source, allowing the use of a windscreen to significantly boost all-condition performance. In addition, the remotely pressurized fuel tank, crude, multi-fuel capabilities and a myriad of overall design improvements boosted function and efficiency far beyond anything else available. It remains the basis of all liquid fuel designs to this day.

Problem: Fuel Availability/Clogged Stoves

MSR Innovation: Fuel-Specific Shaker Jets

The jet, where pressurized fuel escapes the stove to create a flame, was the Achilles heel of early liquid fuel stoves, especially with unpredictable international fuel sources. Our two-fold solution began with the first field-replaceable jets, sized to match the viscosity and carbon-collecting tendencies of fuels ranging from highly refined white gas to rough-burning diesel fuels. Adding a floating pin inside the jet came next, allowing the stove’s jet to be purged of obstructions with a simple shake.

Problem: Reliability

MSR Innovation: Field-Serviceable Stoves

Reliability is the cornerstone of every MSR product, but we also know that people lean hard on our gear in remote places. If something breaks north of the Artic Circle, it needs to get fixed. That’s why we’ve engineered our liquid-fuel stoves to be virtually resurrect-able from the ground up, with a simple, all-in-one tool and a basic maintenance kit. From cleaning a fuel line in the field to a complete refurbishment on the workbench at home, MSR stoves are built like no others, for generations of reliable performance.

Problem: Stove Efficiency in Windy Conditions

MSR Innovation: Primary Air Combustion

We didn’t invent primary air combustion, but we were first to bring it into the backcountry. Typical combustion requires oxygen (secondary air) around and above the flame, as well as from below (primary air). 100% primary air combustion draws all the air needed from below, allowing a completely enclosed flame, significantly boosting the efficiency of combustion. The clear benefits of needing less fuel overall are amplified by the all-condition reliability of a flame impervious to wind, making our Reactor ® and WindBurner ® stove systems unrivaled in real-world performance.

Problem: Excess Fuel Demands/Heavy Packs

MSR Innovation: Hyper-Efficient Cookware

The efficiency of MSR stove systems would not be possible without cookware engineered to make the most of it. Fully enclosing the burner, our advanced Reactor and WindBurner cook pots are built to not only block wind, but also to maximize heat transfer by trapping hot combustion gases around the pot for longer, and boosting the surface area where that transfer takes place. Like the rest of our cookware, we do it all with the best materials for the job at hand to ensure you can tune your kit to the priorities of any trip.

Problem: Consistent Canister Performance

MSR Innovation: Pressure-Regulated Stoves

Canister stoves rely on the low boiling point of fuel to generate pressure through vaporization inside of the canister. However, internal canister pressure can range from 70 psi in summer to just a few psi in cold temps, with low fuel levels, or during long stove runs. We’ve optimized our pressure-regulated stoves to operate optimally at low pressures, assuring consistent performance in the widest range of temperatures possible and minimizing wasted fuel.
