Sprinkler bulbs do not only contain a special filling liquid but also a small bubble. The size of this
bubble is decisive for the operating temperature. When the bulb is warmed up the filling liquid expands
and therefore reduces the bubble until it is completely gone into solution. Further warming leads to a
rapid increase in pressure inside the bulb which makes the bulb burst and thereby releases
the sprinkler mechanism.

The Response-Time-Index is the key figure for the reaction time of a sprinkler bulb. The lower the RTI
of the sprinkler bulb , the faster the response time of the bulb will be.
Assembled sprinkler bulbs have to resist high compression load for many years. The crush strength
of Geissler Sprinkler bulbs exceeds that load many times over. For applications with exceptionally
high requirements for crush strength, Geissler has developed the " GS-bulb.
