Ceasefire UK Kitchen Systems

Domestic Kitchen ranges

These systems operate completely independent of any power source. They require no electrical connection to protect the cooking area.

Stored pressure Nitrogen pressurizes the container and fire fighting agent and is ready for use at any given point, the same as a portable fire extinguisher. The difference is that the system is activated by a small diameter tube that is sensitive to heat.

If a flame is present the tube will heat up and burst at the point where the fire is releasing pressure from the container. In turn, this allows the extinguishing agent to be sprayed from the nozzles directly at the cooker hood.

We have the option of two different extinguishing agents to suit all environments and situations.

Wet Chemical

This fire fighting fluid is a man-made chemical, extremely proficient at instantly knocking down flames and rapidly cooling the area. The Wet Chemical agent used also suffocates the fire through saponification. This chemical reaction of the fluid turns any oil it is in contact with into a foamy solution. Cutting off the oxygen to the fire and fuel supply whilst quickly cooling the temperature below the flashpoint.

How The Agent Works

The extinguishing chemical is a foaming agent that is ideal to fight Class A, B and F fires. It is also environmentally friendly as it’s more than 99% biodegradable (up to 72% within three days). The wet chemical extinguishing agent has a blanketing effect on the flames, which cools the oil to below its self-ignition point.

In contrast to normal Class B fires where temperatures in the range of 350 ̊C-380 ̊C are observed only in the burned fuel or their vapour, the oil used in cooking is itself at this high temperature. Being a de-greasing substance, the extinguishing agent ensures that the kitchen can be cleaned easily post a fire.

How the System Protects

The Wet Chemical Kitchen Suppression System incorporates both manual and automatic protection by a pneumatic detection and actuation technique. All sensitive areas susceptible to fire such as fire due to overheated cooking oil in vessels/deep fat fryer and oil residual deposits in the extraction system of kitchen hoods are covered by a pressurised heat sensing tube. The heat sensing tube is connected to the head of the indirect low-pressure valve mounted on the top of the pressurised agent container. In case of fire, the heat sensing tube punctures at a pre-determined temperature, releasing the pressure of the tube and activating the indirect valve. The extinguishing agent thus released is spread through distribution piping from the nozzle provided to cover the kitchen hood, vessels, plenum and duct.

  • LPCB Certified System
  • No flooding-related collateral damage
  • Fights Class A, C and F (oil) fires Uses biodegradable foam, which also acts as a cleaning agent
  • Its heat-sensitive tube offers superior uniform protection as compared to conventional PointDetector-based Systems

Pros of Wet Chemical System

  • Unparalleled firefighting potential
  • Immediate knockdown of flames
  • A smaller system is required
  • Wet Chem agent acts as a cleaning solution aiding in the clean-up post fire

Cons of a Wet Chemical system

  • Refilling post discharge is costly
  • Any food in the cooking area must be disposed of if contaminated with Wet Chemical agent
  • Clean up takes longer

Watermist

Watermist is quite simply, filtered clean tap water. It’s common knowledge that there is no extinguishing agent more potent than water. With its massive cooling power of 2.6 MW per litre per second, water kills even the largest of fires in minutes. But even fire’s worst adversary has its shortcomings. Using water on oil fires or an electrically started blaze can be a fatal mistake. What you need is cutting-edge technology that changes water’s natural physical form, so that it can fight kitchen fires without causing any collateral damage.

First, the Multi-Rotors and Nozzles located within the system turn water into droplets of 54 micron-size by mixing it with air in a pre-set proportion.

This makes it the only system of its kind that combines two revolutionary technologies–Watermistand stored pressure–into an extinguisher that can take down even the largest of fires, including oil and electrically started fires.

This produces Watermist, which increases the coverage area of water to fight fires many times over. The stored pressure technology is used to deliver Watermist with a kinetic force strong enough to overcome the fire’s own convection currents.

When Watermist falls on the fire, it rapidly brings down the temperature to below combustible levels, cuts o-the oxygen supply and kills the flames.

The huge benefit of Watermist is that it is an absolutely clean extinguishing agent. This means it doesn’t cause any damage; either to the expensive kitchen equipment or food items. Allowing the kitchen to get back into action without any significant downtime.

  • LPCB Certified System
  • No collateral damage and zero downtime due to contamination thanks to Watermist
  • An eco-friendly alternative to conventional extinguishing systems.
  • Works on class A, B, C, F (oil) fires and fires involving electrically charged devices.
  • Specially designed nozzles that use minimum water and give maximum extinguishing power.
  • Its heat-sensitive tube offers superior uniform protection as compared to conventional PointDetector-based Systems.

Pros of Watermist

  • Rapid cooling of the cooking area
  • Cheap to refill after a discharge
  • Easy to clean area after discharge
  • Little to zero collateral damage
  • Evironmentally friendly

Cons of a Watermist System

  • Slightly higher initial cost of the system due to larger capacity of cylinder and nozzles required
  • Slightly larger cylinder required

As somebody who feels that it should be a necessity for all properties to have fire sprinkler systems, I am a big fan of this company. I have used them numerous times to service my home system and they are very knowledgeable. I would highly recommend their service.
