ALL TYPES OF AUTOMATIC \ MANUALLY OPERATED HEAT \ SMOKE \ GAS DETECTION AND FIRE EXTINGUISHING SYSTEMS
Vimal Fire Controls is a Pioneer in providing world Class Fire Safety and Protection products/solutions. One of the products in their portfolio is Foam Flooding System. The Foam Flooding Systems are similar to Water Mist fire suppression systems but use an expanding foam solution mixed with water to extinguish the fire.
There are three types of Foam Flooding Systems: Low / Medium / High Expansion Foam Flooding System. Low Expansion, where the bubble expansion ratio is small (less than 20:1) and the bubble contains a high water content.
Medium and High Expansion, where the expansion ratios are greater from 20: 1 & up to 1,000: 1 respectively. At these expansion ratios, the bubble water content is low and the bubble is relatively light. The foam bubbles are made by mixing a foam concentrate with water to make a foam solution. The foam solution is then mechanically agitated to form bubbles.
Foam suppression systems are useful alternative to tank and pump system based sprinklers. It is particularly useful when there is a particularly high risk of high flammable liquid which may need cover.
Automatic or manual fire detection can be used to release a foam and water mixture which will expand on release of the agent and give a large fire rating cover without the need for large storage or pump tanks.
Features and Benefits:
This System is intended to prevent or extinguish fires automatically within seconds, where there is electrical or sensitive electronic equipment serving a critical operation, the loss of which would not only be the value of the equipment but also the cost of business interruption such as caused by damage to Server Room, Data storage room.
FM-200 or HFC-227ea is chemically known as Heptafluoropropane or Clean Agent Fire Suppression System, which is a fire suppression agent. HFC-227ea Fire Suppression System offered by us is internationally accepted as providing an ideal fire protection solution for people, property and the environment. Electrically non-conductive, its primary action is through cooling the fire and removing heat energy so that the combustion process cannot be sustained. The molecules absorb heat so that the temperature of the flame falls to a point below which it cannot propagate, and the fire is extinguished. The oxygen depleting effect is minimal as only small quantities of the gas are used.
These fire suppression systems can protect Class A, B and C type fires and has zero ozone depletion potential. It has a zero effect on the earth's stratospheric ozone layer and has a minimal impact on the environment in comparison to the impact of a catastrophic fire.
We also have solution for Novec 1230 in both Cylinder and Cylinderless Option.
Features & Benefits:
The extinguishing powders used in powder extinguishing systems are highly efficient, quick-acting extinguish agents. The sudden extinguishing effect of the powder cloud is caused by the suffocation effect and the anti-catalytic effect, a chemical intervention into the combustion process. Extinguishing powders mainly consist of non-poisonous inorganic salts mixed with waterproofing and pouring agents. They are used for fires with solid, liquid or gaseous substances and for metal fires, thus, they are used for fire classification A, B, C and D.
DCP can be used in various applications areas like: chemical works, petrol dumps, compressor and pump stations, utilities substations for oil and gas, gas burner stations at boiler plants, oil cellars, rolling mills, test stands, hydraulic systems, aircraft hangars, LNG, LPG and chemical tankers, laboratory rooms and equipment, hazardous waste systems.
Features & Benefits:
Carbon dioxide (CO2) flooding system. A fixed installation designed to displace the oxygen in the protected space and thus extinguish the fire, usually used to fight fires in engine rooms, boiler rooms, pump rooms and holds. The system normally consists of a series of large CO2 cylinders. CO2 at atmospheric pressure is a colourless, odourless and electrically Non-Conductive inert gas. It has high expansion ratio, which facilities rapid discharge and allows three dimensional quick penetration in the entire hazard area.
Features & Benefits:
The foam pourer is designed to discharge fully aspirated foam directly to the annular seal area of the open top floating roof storage tanks for fire or vapour suppression. Fully aspirated foam provides the most effective performance for all types of foam concentrates.
The cover of the unit, opposite of the foam solution inlet, is designed for removal to allow for internal inspection. The unit can be mounted on the top flange of the fuel storage tank utilizing the mounting holes located in the base of the rim seal foam pourer or by the use of clamps.
A screened air inlet, conforming to the cylindrical body, allows uniform air distribution into the foam solution stream to generate expanded foam. This design also helps prevent damage and inhibits the entrance of foreign materials.
Application:
Fire hydrant pump systems (also known as fire pumps, hydrant boosters, fire water pumps) are high pressure water pumps designed to increase the fire fighting capacity of a building by boosting the pressure in the hydrant service when mains is not enough, or when tank fed.
Fire Hydrant Systems forms the basis, of Fire Protection Systems, without Fire Hydrant System a Fire Protection System cannot be called a Fire Protection System. It will be a superficial system. Fire Hydrant Systems are very strong and can be used from medium to large sized fires. Fire Hydrant Systems, have a long range. Since the Fire Hydrant System is spread out, the fire hydrant can attack fire from different angles. This entire systems requires low maintenance and virtually, does not leak water. Besides this, Fire Hydrant Systems have a long life.
The hydrant vertical post and hydrant arms is made up of seamless black steel tube of heavy duty conforming to IS: 1239. Each assembly is hydro-tested to a pressure of 15 kg/cm2 to check for flanged joint leaks. Each Hydrant post is painted with Fire Red colour paint and supplied along with all required accessories.
It is virtually used in all major Industries including, Oil & Gas.
A Water Spray System, for Fire Protection a different variant of Fire Sprinkler System. Such a system is used in places where fire is likely to rapidly spread out of control, within a short duration. Examples of such places, where Water Spray System, for Fire Protection are required are; Transformers, LPG bullets and Combustible fuels.
When the fire take place, the detector ring detects this; and gives the signal to the deluge valve or all the sprinkler surrounding the transformer to start all at once. Hence the entire transformer is flushed with water, to cool it down.
There are two main variants of Water Spray System, for Fire Protection:
Water Spray System comprises of complete set of pumps-motors, isolation valves, control valves, flow meters, pressure measurement and spray nozzles along with other necessary instruments & all relevant accessories, assembled into one compact unit easy to install and operate.

Medium velocity spray system is water spray of finely divided droplets at medium velocity. They are ideal for protecting hazards involving light oils where emulsification from high velocity sprayers is not possible. The fine spray has a high heat absorption rate so medium velocity sprayers are an effective method of protecting adjacent plant and structures from heat during a fire by providing a continuous cooling spray over the exposed surfaces. Keeping nearby equipment cool minimises damage and reduces the risk of explosion.
Medium velocity water spray system is designed to control fires involving the lighter oils, liquefied petroleum gases and other flammable liquids with flash points below 650 C.
Cooling smothering and dilution play apart in varying degrees with such a system. This type of system utilizes sprayers which produce a medium velocity water discharged with directional properties operating at a minimum water pressure of approximate 20 P.S.I. sprayers can be arranged for individual automatic operation or for automatic and manual operation in groups to command the plant or fire area concerned. Here again, the essence of the design is proper discharged pattern, careful hydraulic calculation and balance of flow and pressures. All systems are fitted with alarm equipment and monitoring devices as required.
Medium velocity water spray system has been developed and extensively installed for the following applications.
For fire risks involving the lighter oils, liquefied petroleum gases, and other inflammable liquids, where it may not be possible or desirable to extinguish the fire completely.
For the protection of vessels, plant, and structures exposed to heat from adjacent and surrounding fires
A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. This type of equipment is used to detect a gas leak or other emissions and can interface with a control system so a process can be automatically shut down. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion. This type of device is used widely in industry and can be found in locations, such as on oil rigs, to monitor manufacture processes and emerging technologies such as photovoltaic which can be used in firefighting.
Gas detectors can be classified according to the operation mechanism (semiconductors, oxidation, catalytic, photoionization, infrared, etc.). Gas detectors come packaged into two main form factors: portable devices and fixed gas detectors.
Portable detectors are used to monitor the atmosphere around personnel and are either hand-held or worn on clothing or on a belt/harness. These gas detectors are usually battery operated. They transmit warnings via audible and visible signals, such as alarms and flashing lights, when dangerous levels of gas vapours are detected.
Fixed type gas detectors may be used for detection of one or more gas types. Fixed type detectors are generally mounted near the process area of a plant or control room, or an area to be protected, such as a residential bedroom. Generally, industrial sensors are installed on fixed type mild steel structures and a cable connects the detectors to a SCADA system for continuous monitoring. A tripping interlock can be activated for an emergency situation.
Advantages:-
The Gas Monitoring System (GMS) is designed to work with two LPG sensors. This allows a greater coverage of gas detection. The GMS is also supplied with a solenoid valve which is installed in your gas supply. Your gas supply will then be controlled by the GMS which has a button to open/close the valve. In the event of an alarm, the GMS will automatically close the valve to switch off the gas supply
The power supply will be either 12v or 24v. The power supply must come from the vessel's Master Switch in order to activate the Gas Monitoring System whenever the power is on.
The main unit should be in a location where the alarm is audible and the LEDs can be seen. It must be in a location that is protected from the elements and the ventilation holes should not be covered up. The gas detectors should be mounted in the lowest possible position where they will remain dry. The most suitable location for the detector is near any gas appliance at floor level or just under the floorboards. There are four holes in the bottom of the case for routing the supply, detector, and valve cables. There is also a larger hole in the back of the system if needed. The solenoid valve should be connected downstream of the regulator and as close to it as possible.
