lwatani System maintains constant pressure as fuel is being consumed, providing the maximum and consistent output for the life of entire fuel canister. It also allows the stove to utilize the entire can of butane leaving no residual fuel, assuring greater economy and safety. The special inner flame burner head allows the flame/heat to be concentrated more in the center of the cookware as opposed to heating the outer and side portions of the pot or pan. This allows the stove to have the fuel usage of only 10,000 BTU/hr but perform like a 12,000 BTU/hr stove. The EcoPremium comes with a non-stick steel drip pan. This makes for easy cleanup of messy spills and helps to keep the EcoPremium looking like new. The burner head on the EcoPremium is located further away from the fuel compartment than traditional stoves while keeping its compact size. This special feature makes it possible to use 11.5" diameter cooking utensils without the utensil overhanging the fuel compartment which may cause the fuel canister to overheat. This lwatani System feature replaces locking levers. Simply push the fuel can onto the magnet and it locks in safely making it virtually impossible to load fuel can incorrectly.
