Primus Ulti Stove System 1.7

Ulti Stove System 1.7L is our most windproof and high-performance gas stove, built to handle demanding conditions—from high-altitude mountains to desert expeditions. Despite its compact and lightweight design, the reliable 3,000W burner efficiently melts snow and boils water for 2–3 people.

Reliable performance in extreme environments
Melt snow, boil water, or heat food in the harshest conditions – Ulti’s innovative burner has no blue flame that can be extinguished. Its compact design makes it easy to operate while wearing gloves, and the three sturdy legs and low center of gravity provide stability on any surface. Simply lock the handle in the open position, place the integrated heat exchanger pot on the burner, and you’re ready to boil water. In extreme cold or when the gas canister pressure is low, you can invert the stove for improved fuel flow—but always ignite the stove in the upright position and preheat for at least one minute before inverting. Always follow the instructions for safe handling and proper fuel supply.

Compact expedition stove with a pot
Ulti Stove System 1.7L is an all-in-one stove kit that includes everything you need to prepare a hot meal, no matter where you are. The set consists of a wind-resistant burner with sturdy legs, a pressure regulator, and a remote-canister hose system. It also comes with a 1.7-litre pot with a spout and integrated heat exchanger, a lid—both made from hard-anodized aluminum—and a mesh storage bag for the burner. Gas is not included—purchase Primus Power Gas, Summer Gas, or Winter Gas separately.

Innovative burner with no flame
Ulti is our most windproof stove, featuring a flameless burner that combines catalytic combustion and infrared radiation, eliminating the risk of flames being blown out. The 3,000W burner boils 1 liter of water in just 3.5 minutes, with a pressure regulator ensuring consistent and high heat output. Always use the gas canister in the upright position. In extreme cold or low-pressure conditions, you can invert the fuel canister for better performance but always ignite the stove in an upright position and preheat for at least one minute before inverting. Always follow the instructions for safe handling and correct fuel supply.

Maximize your Ulti stove
Ulti Stove System 1.7L is a complete stove and pot kit, but you can enhance it with the PowerLighter, which works in all weather conditions. For different meal sizes, add the Ulti Pot 1.0L for 1–2 people or the Ulti Pot 2.5L for 2–5 people.
