 KITCHENShield

Electric and Gas-operated cooking appliances in the kitchen use large amounts of flammable ingredients and are in particularly high danger of ignition and fire outbreak.

The system caters to the needs of both small and large kitchens such as those in hotels, restaurants, hospitals and public institutions.

Features and Benefits

  • Fast detection – quickly detects fires to minimize damage and injuries.
  • Stainless Steel friendly – The extinguishing liquid has a low acid level (below pH:9) and protecting stainless surfaces
  • Dual Action – Simultaneously extinguishes the fire while interrupting the energy supply.
  • Environmentally friendly – water-based agent not harmful to the envireonment.
  • Custom made solutions – Custom designing, modeling testing, and manufacturing of fire suppression systems to meet customer’s diverse requirements.
  • Proprietary Technology
  • Fast installation
  • Flexible mounting of the discharge piping distribution
  • Simple design of the discharge piping distribution, flexible mounting of the manual pull station and gas valve.
  • Mechanical system – Does not require N2 or CO2 cylinder to operate the dry chemical agent.
  • Multiple cylinder – Largest amount of cylinders (up to 6 unites) and longest distance between them in one system in the market.
  • No crimping needed inside the MR

Kitchen Fire Suppression System

Simple and easy to maintain system effectively protects kitchens in hotels, restaurants, and public institutions with a high risk of fire.

The system protects the duct, hood, and cooking appliance areas using a continuous cable that connects all cooking devices with stragically placed detectors.  Each detector is comprmised of four parts: detectors, a bracket, two “S” links, and a fusible link.

As the heat builds the fusible link will separate at a predetermined tempereature relieving tension on the cable and activating the system.

  • The system is operated automatically or manually according to customer requirements.
  • Temperature detection levels can be adjusted to suit the application.
  • Heat detectors are installed within the plenum and are triggered only during fire, while nozzles are arranged to offer maximum extinguishing coverage of all cooking appliances.
  • A manual pull station allows immediate response capabilities backing up the automatic suppression system.
  • The system distributes the extinguishing agent all over protected areas, while interrupting the energy supply of gas and electricity of maximum protection against pre-ignition.
  • Potassium hydroxide phosphate is used to extinguish cooking oil/grease fires. Upon contact with the oil, the liquid creates foam, preventing oxygen from reaching the fire and cooling area.
  • All system parts are attractively styles, so as not to detract from the look of the kitchen, while the design ensures that kitchen workspace is not disrupted.
  • After system operation, the kitchen can be ready to be re-utilized within minutes.
  • The system can be recharged and ready to work in a very short period of time after discharge.

Fusible link: Melted by heat, the two halves of the link will separate operating the extinguishing agent.
Detector bracket: Supporting the fusible link and the continuous cable under tension.
Mechanical release module (MRM) Accomplished when a fusible link separates in a fire condition and releases tension on the cable causing a spring-loaded trigger to activate the cylinder discharge valve.
Nozzles: Liquid agent stored under pressure when activated is transmitted through supply lines and discharged through nozzles.
Manual Pull Station: Each Lehavot WCK system is equipped with at least one manual pull station providing a means of activating the system manually if required.
Extinguishing Agent: The Lehavot extinguishing agent is based on a potassium compound that extinguishes cooking oil fires by means of cooling and saponification.
