• Designed for various risks of kitchen fires
• Akronex?s fire suppression systems into kitchen hood and fire extinguishing agents of Akronex are designed and manufactured, according to UL standards
• Easy to clean and to refill after fire

APPLICATION
Akronex?s liquid agent is designed to use in fire fighting systems into hoods and K class extinguishers. This liquid agent is effective against fire caused by oils that accumulate onto kitchen equipments and ventilation systems. Do not use at fires arising from the electrical circuits.
DESCRIPTION
Akronex?s liquid is a specially designed chemical inorganic salt solution. The agent is pre-mixed, therefore eliminating necessity of distillation before system?s filling. When used as fire extinguisher the agent doesn?t reveal any toxic substances.
PROPERTIES OF AGENT
Appearance ???????????????????? : Pure, clear liquid
Expiration date????????????????????? : 12 years
Refractive index???????? : 1,39-1,41
Freezing point???????????? : -40C
Specific weight ?????????????? : 1,32-1,52
Kinematic viscosity : 3,2cs @ 25C
pH :12,5-13,5
WARNING: Be careful when using the agent. In case of contact with eyes or skin should be rinsed with water within 15 minutes. In case of absorption of agent, drink milk or water and immediately seek medical advice.

PERFORMANCE
Application of Akronex?s wet agent with Akronex?s fire suppression systems inside hood or Akronex?s extinguishers is more effective in fire fighting into ventilation systems (exhaust, chimney, etc.) and stoves (deep fryers, cookers, wok, grill etc.) Acceptable environmental temperature is 49oC. The fire extinguisher reaches the burning surface of kitchen equipment, cooling them and reacts with hot fat (saponification reaction), forming a soap suds layer on the fat?s surface. This layer performs the function of insulation between the hot fatty film and atmosphere, preventing the release of flammable vapors and oxygen supply, thereby eliminating the risk of reigniting.

TECHNICAL SPECIFICATION OF FIRE SUPPRESSION SYSTEM IN HOOD

1. SUBJECT:
1.1 1.1 This specification presents the technical characteristics of fire fighting systems consisting of detection and automatic extinguishing of a possible fire on kitchen equipments with high fire risk: chimney, hoods, filters, stoves, ovens, grills and other similar items for cooking.
2. SCOPE:
2.1 2.1 This specification includes a wet chemical agent, applied for kitchen hood systems; storage cylinders of fire extinguishers, fire detection and mechanical discharge units, discharge nozzles and other developed materials of auxiliary equipments; and installation manual.
3. MAIN CHARACTERISTICS:
3.1 Each system integrally with each other makes a single unit, and all items will be product of the same manufacturer.
3.2 Design of hood systems, scale drawing of kitchen layout is based on the norms of NFPA (96 and 17A) and UL300 standards.
3.3 The system is activated by detectors inside hood or by manual activation button, installed on the evacuation routes, and extinguishes the fire discharging the wet chemical extinguishing agent that does not harm the environment where were discharged.
3.4 All units used in the system approved by UL300. The company will specify this fact in the quotation.
3.5 For each group of devices and hoods, which are the subject of risk will be applied a single system.

4. TECHNICAL CHARACTERISTICS:
4.1 DESIGNING
4.1.1 System design is carried out, by the scale drawings of kitchen layout provided by administrator or by results of Contractor?s calculation after studying of kitchen layout, according to norms of NFPA (96 or 17A) and UL300.
4.1.2 The company will provide administrator with draft decisions, main criteria for designing, method of payment in quotation, referring to the relevant items of the relevant standards, together with scale drawings.

4.2 MATERIALS
4.2.1 Wet chemical agent: Wet chemical agent based on potassium with low level of pH is effective solution, which rapidly extinguishes fire, don?t making adverse effect to environment of discharge
4.2.2 Storage cylinder of wet chemical fire extinguishing agent: cylinders should be made of stainless steel. According to working pressure 20?? DE 175 PSL, it pressurized by dry nitrogen. Operating status of cylinder can be controlled through the manometer. The valves on the cylinders shall be made of brass. Cylinders are red painted by RAL 3000.
4.2.3 Device of mechanical discharge: mechanical discharge device is a box made of stainless steel with a fixed cap on the front side, which pushes the moving gas into cylinder of fire extinguisher by spring, pneumatic and mechanical way. On the cover will be plate, indicating the device status (ready/active). Attached manual start contact, providing manual activation of system, operation of which is blocked under normal conditions by disk.
4.2.4 Nozzles: Every used type of nozzles will be tested and approved for application in special restaurant systems. Nozzles are made of brass of chrome finish. On the spraying part on chrome finish are labeled form and flow rate of spray. Supplied with filter preventing clogging of nozzle. In addition, there is a plastic cover opening during discharging.
4.2.5 Detection system: there is mounted detector with metal insurance (activates at 182oC), which detects the heat rising from fire inside hood or on the stove and metal insurance is disconnecting in result of melting. Detection wire made of solid steel material is mounted and taut between detector and mechanical discharge device. Principe of operation: Due to high temperature during the fire till 182oC DE detector with metal insurance is melted and disconnected, fire detection wire is weaken and thus mechanism of discharge is started.
4.2.6 The line of discharge: the discharge line is made of seamless stainless steel pipes. Galvanized pipe and galvanized fittings are strictly not used. Pipe joints are not flexible and on bends it is necessary to use fittings. Will be used teflon seal for hermeticity. Out surface of the joints and pipes will be cleaned from dirt, grease and rust. Pipes are mounted in such way that can withstand to vibration and impacts.
4.2.7 Manual start button: two wires sensitive against fire, one passing through a line from mechanism and the other through a separate line are connected to the device. When you press the button, these wires are stretched, thereby activating the mechanism.
4.2.8 Key contact: Key contact with one out will be used to send a signal into existing alarm system mounted inside discharge device, open and close the electric stoves and other devices running on electricity.
