Controlled Atmosphere Attachment

Controlled Atmosphere Attachment - for testing specimens in low oxygen atmospheres  (0-21%) that may be found in well developed fires, or for studying the effects of gaseous suppressants or other dynamic controlled atmosphere environments. The cone assembly is located on top of the enclosure with exhaust gas exiting only through the cone only. The cabinet replaces the conventional cone assembly but uses the same controllers as the normal cone operation. There is a door on the front of the assembly with a viewing window. Changing between the standard fire model and this unit is very simple and takes approximately 10 minutes. The Cone Calorimeter is fitted with a gas mixing attachment to mix air and nitrogen which can be supplied at flows between 0 - 280 l/min to the chamber. The gas supply lines are fitted with flow meters and flowstat flow controllers and a mixing chamber. These are external to the enclosure chamber and housed on the main Cone Calorimeter chassis.
