O2 generator/chemical candle temp query

[No_Speed_Restriction]

Apart from the warm oxygen delivery temperature I was just wondering to what temperature can one expect the O2 unit in the PSU to get up to?

The hair spray-size generators produce oxygen by heating chemicals at close to 1,200 degrees Fahrenheit. They are activated when the firing pin is pulled, usually when a passenger pulls the mask from an overhead compartment.


Once installed, the canisters are heavily insulated to protect the plane from damage or fire, but the surfaces of some models can reach temperatures as high as 500 degrees
