Products for the Hygiene industry
Firefly generally uses the following products in a system designed for the Diaper industry:
DETECTION
EXTINGUISHING
CONTROL
Open Area Detector (OAD2)
The OAD detector detects flames in open areas. By combining ultraviolet (UV) and infrared (IR) wavelengths, this detector will efficiently recognise flames. At the same time, other energy sources such as lamps, sunlight or even arc welding are discriminated.
Water Mist nozzle
This water nozzle sprays fine water particles. Its capacity is 10 litres/minute and it has a 180° spraying angle at 6 bar.
Control Unit (CUE)
Each protection zone is controlled by a control unit type CUE. The CUE has a self-diagnostic function, battery backup, flexibility and is user friendly.
Flame Detector (FD)
The FD detector is designed for flame detection in enclosed volumes.
Water Spray nozzle
Water nozzle of full cone type. This nozzles capacity is 90 litres/minute and it has a 110° spraying angle at 6 bar.
Glow Detector (GD)
The GD 400 detector can be used for monitoring pneumatic conveyer systems and chutes. For protection of risk zones where material occurs in dust clouds, e.g. filters. This detector recognises sparks, hot particles and flames from 400°C (752°F).
Isolation valve (GIV)
The GIV valve has a guillotine design and is intended for installation on pneumatic transport systems. The valve is available in different dimensions up to Ø600 mm. The GIV valve is often used for lean phase processes.
Trend Detector (TD)
The TD 250 detector can be used for monitoring pneumatic conveyer systems and chutes. For protection of risk zones where material occurs in layers (e.g. storage silos) and also where material has fairly low ignition temperature. This detector recognises sparks, hot particles and flames from 250°C (482°F).
Isolation Valve (FIV)
The FIV valve has a guillotine design and is intended for installation on pneumatic transport systems. The valve is available in different designs and dimensions up to Ø300 mm. The FIV valve is often used in dense phase environments.
Isolation Valve (BIV)
The BIV valve has a throttle design with a spring tensioned controller that is electrically controlled. It is ideal for installation in piping where finely distributed material is transported. The BIV valve is available in different dimensions up to Ø600 mm.
Isolation Valve (DIV)
The Firefly valve type DIV is a fast acting valve intended for applications where extinguishing with water or gas is unsuitable due to process conditions. The valve is fitted with a spring tensioned pneumatic controller and is available in dimensions up to 500x500 mm. The valve fully diverts in less than 300 ms.
CO2
Carbon dioxide as an extinguishing method is efficient, especially for enclosed volumes. The CO2 will displace the oxygen and thereby suffocate the fire. The CO2 is contained in bottles and is released by a solenoid valve.
