Refridgerated Warehousing - Cold Stores
Warehouses - by their very nature, are large volume open areas with high roofs in order to maximise on storage capacity. In some cases, the buildings remain large shells into which items may be stored in bulk. In others, roll cages and multi-level racking is installed to assist with product identification and selection for onward transportation/distribution.
It is essential to continuously monitor, rapidly detect and onward signal to authorised personnel or a central system control panel, any abnormal temperature rise - which may be associated with an overheat or fire situation. Point type detection devices are not suitable for installation within warehouses for a number of reasons:
- Their roof mounted installation relies upon favourable airflows** to enable detection
- Exhaust fumes from vehicle loading bays repeatedly generate false alarm signals
- They require high levels of annual maintenance
- Their continuous uninterrupted operation is affected by condensation
- Many are not suitable for continuous exposure to sub-zero temperatures
** Typical adverse airflows found within warehouses (for rapid overheat/fire detection) are air turbulence from evaporator fans, hot lighting and drafts from loading/unloading bays.
The PROLINE TH DIGITAL LINEAR HEAT DETECTION system is a continuous detector and cable in one - FM APPROVED AND UL LISTED - which can be installed very easily and cost effectively at the exact point of risk and able to signal a pre-determined alarm temperature - regardless of whether 1% or 100% of its installed length is exposed.
Installation and continuous un-interrupted operation of the TH sensing cable is unaffected by dirty, damp, corrosive environments, areas of limited access and surveillance and sub-zero ambient temperatures (UL listing tests to -30C/-22F, F.M approval and manufacturer tests to -40C/-40F). Low maintenance requirements further support the TH sensor cable product specification and selection.
Individual single zone lengths of 2000metres/6500 feet - or even 10,000metres / 32,800 feet where required - may be installed with identification of the point of alarm available from the sensor cable's associated optional ZI interface unit.
