It is extremely volatile, boiling at 12.5° C. (54.5° F.), and is therefore a gas at ordinary room temperatures; it is stored in glass tubes fitted with screwcapped nozzles.
The four exhaust nozzles are attached to the engine via four circular cutouts in the fuselage side.
HB Series band heaters are used to heat the barrels and nozzles of plastic injection molders and extruders.
Once the heated air leaves the turbines it passes into a bifurcated duct which has a further pair of lateral vectoring nozzles.
Watch out for signs of inefficient printing, and then clean the nozzles in the approved way.
