The new Kidde 400 Series cylinder valve provides both flow and pressure control at the valve, allowing Schedule 40 piping to be used throughout the system. This allows for overall savings in installation costs. The Kidde 400 Series valves also utilises quick connect steel braided pilot lines which allows quick connection between cylinders. Again, offering a reduction in installation time and overall costs.
Inert gas systems that use IG01, IG55, IG541 and IG100 have been in the market for many years. These systems are well recognised by the fire industry as an effective solution in protecting high-value assets such as data centres. Taking into account the potential environmental impact, this system also has a positive impact on the environment as the agent has zero ozone depletion and global warming potential.
There are inert gas systems in the market with flow and pressure control valves that allow the use of lower schedule pipe, Sch40 for example, which results in easier installation due to the lower weight of the piping network. Installation, commissioning and maintenance of a big bank of 100 plus cylinders is still a labour intensive process; consider the labour and cost involved in connecting actuation hoses between cylinders, having them torqued to manufacturer’s specification. Some systems also require a separate device to perform pilot line test during commissioning which means another added cost. In addition, there have been instances where discharge of an inert gas system has lead to damage to mechanical hard drives due to high sound pressure generated as the gas exits the nozzles. One of the key advantages of the new Kidde 400 series system is its quick connection of the pilot line and the valve cap also serves as discharge indicator during pilot line test.
In addition to the common 360-degree nozzles, also available are 180-degree discharge nozzles that provide designers flexibility in placing nozzles in tight areas.
Also introduced for the first time, nozzle silencers are now available for applications that involve acoustic sensitive equipment, such as mechanical hard drives in data centre. The nozzle silencers can also be retrofitted to existing Kidde “469” 300bar and C60 systems without any system modification required. The silencer can reduce sound pressure level to below 100dB dependent on flow rate.
- Reduced pressure 55 bar to manifold
- Schedule 40 pipe can be used throughout instead of Sch80 and Sch160, reduce installation cost.
- Quick connect actuation hoses provide ease of installation, especially for big cylinder bank.
- Nozzle noise reduction down to < 100dB, dependent on flow rate
