What is a pressure regulator?

The pressure regulator is a system that regulates pressure of gas output under different environmental conditions.

Why include a pressure-regulator?

The pressure of the gas cartridge reduces when

1. In cold environments
2. Used in a continuous output longer than 3 minutes

As a result of weaker pressure, the burner flame becomes weaker. The pressure regulator solves this issue by maintaining a consistent output, resulting in a consistent burner flame.


How does the Fire Maple pressure-regulator work?

1. Flame regulator

2. A cabin
3. B pass
4. C cabin
5. Adjustable panels 
6. Gas cartridge

I. After opening the valve, gas flows to C cabin through B pass. Adjustable panels regulate the pressure of output via compressing (when the pressure becomes weaker) or enlarging space (when the pressure becomes stronger) in C cabin.

II. When the pressure inside of gas cartridge increases rapidly to a high level (for example, the gas cartridge is placed in strong sunlight or incorrectly placed near a heat source), B pass will be close automatically and the stove will stop working. This enables the pressure-regulator to also function as a safety device.

Due to the pressure regulator design, the Polaris is NOT recommended for use with any type of propane bottles other than standard threaded camping gas canisters. Use with adapters will result in poor performance. This includes 1-lb propane bottles, large thread propane tanks, etc.


TESTING: Polaris Remote pressure regulator gas stove VS Stove without pressure regulator

To test the effect of the pressure regulator, we did 2 sets of experiments to observe the boiling of 1L of water.

1. At room temperature: the Polaris stove with pressure regulator boiled 1L of water in 3 minutes and 33 seconds, the stove without pressure regulator took 4 minutes and 26 seconds.
With the help of the pressure regulator, 53 seconds were saved.

2. Low temperature environment (lower temperature environment by adding ice next to the gas tank): Polaris stove with pressure regulator boiled 1L in 4 minutes and 17 seconds, while the stove without pressure regulator took 5 minutes and 41 seconds.
With the pressure regulator, 84 seconds were saved

*The testing was carried out in Fire Maple lab:
room temperature 15℃/59℉;
Original water temperature 11℃/51.8℉;
Testing kettle: Fire Maple Feast T4;
Net weight of gas: 106g(full capacity 230g).

Why the new stove deserves to own:

1)Pressure regulator valve, maintains a consistent burner output under various environmental  conditions.
2) Compact folding design, saves space in your backpack.
2)Folding pot stands provide stability for various diameters of cookware
