Reactor Stove System

The MSR Reactor Stove System is an innovative, fast-boiling, fuel-efficient, windproof cooking system. Ultra-efficient, the radiant-heated Reactor Stove System boils a liter of water in just 3 minutes! This ground-breaking stove is coupled with an integrated cooking pot for use as a compact unit.

The Reactor Stove System's state-of-the-art burner utilizes two modes of heat transfer, convective and radiant, to ensure that maximum performance is achieved in varying conditions. The burner is enclosed in a heat exchanger, protecting it fully from the wind and positioning heat directly where you need it, underneath your cooking pot. As a result, heat loss is minimal and cooking time is greatly reduced. An internal pressure regulator equalizes fuel pressure and guarantees a consistent heat output in all temperatures. This frees you from worrying about poor performance in cold weather and makes certain that you are best able to take advantage of any and all fuel available in your fuel canister.

The aluminum cooking pot is designed to work hand-in-hand with the stove itself. It is compact and lightweight enough for solo trips, but large enough to boil water and cook for up to 3 people. The pot is also designed to hold and carry the entire Reactor Stove System as a single, compact unit. 

  • Integrated System: State-of-the-art stove and high-efficiency cookware are combined into a compact, self-contained and easy-to-use system.
  • Unrivaled Boil Time: Outperforms the competition in head-to-head lab tests—boiling .5 liter of water in just 1.5 minutes—with an even greater advantage out in the real world.
  • Unmatched Wind Protection: Heat exchanger completely encloses radiant burner head, virtually eliminating the effects of wind to maintain outstanding boil times and save fuel.
  • Compact Design: Conveniently packs the stove burner, 4 oz. (110g) IsoPro™ fuel canister (sold separately), folding canister stand, and PackTowl® inside the 1.0L Pot. Extra full-sized bowl snaps onto the outside.
  • Maximum Efficiency: Patent-pending radiant burner, heat exchanger and internal pressure regulator produce best-in-class, fuel-sipping efficiency in all conditions.

Complete Reactor Stove Systems are now available in three sizes:

1.0L System: For trips with 1-2 people, or anywhere weight and space are at a premium.

1.7L System: All-around performer with the capacity to boil water and melt snow fast for two or more.

2.5L System: Boils enough for five freeze dried meals at once, or make it an expedition snow-melting powerhouse for 2-3 people.

All Systems Include: Reactor Pot and Stove, BPA-Free Strainer Lid, PackTowl® Pot Protector, and folding/locking handle
