Does anyone have experience installing a heat detector in a cold environment (~ -40 degrees C or F)?
I'm thinking a rate-of-rise detector would probably be the right type based on what I've read but having problems finding a cut-sheet that supports that operating environment. Normally this type of space would get a dry sprinkler but some things have led to trying to think "outside the box" for this project. Thanks in advance. Sent in anonymously for discussion.

Protectowire has a UL and FM linear heat detector that's rated to -40F. System Sensor has their FAAST remote aspirating smoke detector.

Depending on what the extreme low temperature you need, I belive that Fenwal "Detect-A-Fire" might work.

Be careful with detection device (same possible issue with sprinkler heads): if you have some moisture in the air, it may collect at the device location and create an "ice crust" around the device that may prevent its quick and normal operation.

If spot is desired, I would suggest the "302" series by Edward. They are non-intelligent and rated down to -40F. Same concerns as raised by others regarding how linear/ASSD type detection would be acceptable (with ASSD be sure to run the pipe in a warm area with condensate consideration.)

Just to clarify the temperature is -40 F (worst case). I had Celsius in the question by mistake. Thanks for the suggestions everyone!

I had to look twice when reviewing the question today... I believe -40 C / - 40 F is where the two temperature scales meet. I learn something new everyday.
