CARBON DIOXIDE (CO2)
Carbon dioxide is an effective fire suppression agent applicable to a wide range of fire hazards. Carbon dioxide works quickly, with no Residual clean-up associated with a system discharge which translates Into minimal business interruption.
AGENT – HEPTA FLUO ROPROPANE (FM-200(R))
The extinguishing agent used in Rotarex Pre-engineered Fire-Suppression systems Is Heptafluoropropane, more commonly known by its ASHRAE designation: FM-200®.FM-200® is a colorless, odorless, liquefied compressed gas.
(See the Physical Properties Table). It is stored as a liquid, but dispensed into the hazard As a colorless, electrically- nonconduotive, gaseous vapor due to it’s relatively low boiling point.
FM-200® has been tested and verified to be safe for use in occupied Spaces when used as specified in the U.S. EPA Significant New Alternative Policy (SNAP) rules. Tests have proven that exposure to FM-200® is safe and effective in extinguishing fires at low concentrations; most of which are well below the EPA’s Maximum exposure levels.
FM-200® is approved for use in occupied areas up to 10.5% concentration by volume with a mandated egress time of 5 minutes or less.

Thermo-Act
Thermo-act systems are the advanced technology of automatic fire suppression systems. The systems provide a self-activating suppression system that suppresses fires in seconds. They are simple design and installation with low maintenance, highly cost effective and reliable. The electrical or pneumatic sources shall not be required to our thermo-act systems. The systems can be used in the presence of an increased risk of fire. Thermo-act systems utilize fire flexible tube for fire detection. Thus, the fire detection and extinguishing system is not required to detect and discharge.Thermo-act systems can be designed with commercial available agents including clean agent, wet chemical, foam, and dry powder. The systems may be arranged as:
Direct System :
Thermo-act direct system for low pressure agent as shown below uses the flexible tube as both the detection device and extinguishing discharge system. In case of fire, the section of tube most exposed to heat will rupture forming a discharge nozzle. The suppressant agent is then completely released due to pressure drop in the tube.
Indirect System :
Thermo-act indirect system for low pressure agent as shown below uses the tube as a fire detection device only, the fire suppression agent is delivered through a special copper or stainless steel tubing system, once the tube ruptures due to heat exposure, the drop in pressure activates the indirect valve to direct the flow of suppression agent to diffuser nozzles via a fixed tubing system, this system is usually used in large areas.

Kitchenhood fire Suppression
WET CHEMICAL SYSTEMS
A wet chemical system is the most commonly used fire suppression system to extinguish cooking oil fires. It is the primary source of extinguishing kitchen fires. The wet chemicals suppress fire by a process called saponification. Saponification is a chemical reaction that occurs when a vegetable foil or animal fat is mixed with a strong alkali. Saponification value is a measure of the amount of potassium hydroxide needed to neutralize one gram of fat or oil. The most common types of cooking media, i.e., animal fats (or lard), vegetable oils, and peanut oils, have similar saponification values. Other fats, such as cocoa, have substantially higher saponification values and therefore are more difficult to extinguish.
DRY CHEMICAL SYSTEMS
A dry chemical system is primarily used to extinguish flammable liquid fires that are not of appreciable depth. Because it is non-conductive, it can also be used on flammable liquid fires involving live electrical equipment. Dry chemical interrupts the chemical reaction of fire by removing the oxygen from the source. When the multipurpose dry chemical is discharged into burning ordinary combustible, the decomposed monammonium phosphate leaves a sticky residue (metaphosphoric acid) on the burning material. This residue seals glowing material from the oxygen, thus helping extinguish the fire and prevent re-ignition.
