6 AUTONOMY AND POWER
For information, the autonomy of
PYROS 3
is about 58 min using industrial gas cylinder without
flow limiter.
However, the power and autonomy of
PYROS 3
depend on the gas cylinders flow.
The flow of a gas cylinder varies according to two factors:
1. Ambient temperature: The higher it is, the more the rate will be important.
2. The duration of use: The longer it is, the more the possible flow will have to be low.
Number of achievable burns with 2 Propane gas cylinder 13 kg:
This table is estimated. The values are approximate and for an ambient temperature of 15°C.
