Job Thermo Bulbs GmbH

Product Description

JOB THERMO BULBS are thermally actuated release elements for automatic sprinklers, smoke vents, fire dampers and other release devices. A hermetically sealed liquid (G or F-type) in the glass bulbs expands with rising temperatures breaking the bulbs into small fragments at a predetermined release tem- perature. The unique bone shape design of JOB THERMO BULBS (US Patent No. 4,796,710 and other international patents) combined with the special liquid (F-type; US Patent No. 4,938,294) are decisive factors for the outstanding thermal response perfor- mance and strength of the glass bulbs. All the main features of JOB THERMO BULBS can be taken from the above chart.

The Latest Generation of Glass Bulbs

The latest developments in sprinkler design require glass bulbs having extremely low Response Times and very high strength characteristics. JOB has established a development team that continuously improve the quality and the characteristics of JOB THERMO BULBS in order to fulfill the needs for high quality and leading technology for life safety products.

JOB Thermo Bulbs

With their unique bone shape design rein- forced ends are used to absorb loads from the mounting supports and to introduce these axially into a shaft of reduced diameter thus avoiding unfavourable shearing and bending stresses in the glass. Furthermore the out- standing tension condition allows a low mass structure, which, combined with the special filling liquid, provides very low Response Times. Because of these characteristics JOB is the world-wide leading company for the supply of glass bulbs with superior thermal response and strength.
