Water spray systems Safe for certain.
WATER SPRAY EXTINGUISHING SYSTEMS
Every year, fires cause hugedamage and cost the economybillions of Euro.A special fire hazard is causedby substances that are highlyflammable which are likely to cause a very quick firespreading. In such cases, con-ventional sprinkler systemsmay not be activated quicklyenough to provide adequateprotection.
Minimax has therefore de-veloped water spray systemswhere all nozzles in the affected area are openedsimultaneously covering thearea with a water spray. Alarge volume of water is thusreleased and sprayed evenlyover an extended area withina very short period of time.This approach ensures thatfires in rooms with flammablegoods can be extinguishedquickly and with minimumdamage.
Minimax water spray systemsare designed according to theindividual needs of our cus-tomers and the fire protectionrequirements at the site,taking into account the ac-tual fire load, structure of the building or the protectedobject.
Generally, the costs of a waterspray system amount only to a fraction of the overall con-struction costs of the buildingespecially, if the extinguishingsystem is incorporated intothe building project duringthe planning phase. Thanks toits many years of experienceMinimax can further offerwater spray systems for re-trofit installation at a verycompetitive price.
Minimax water spray systemsprotect your company againstthe devastating effects of afire, as such events generallylead to a long standstill. Byinstalling a well-designed andeffective fire protection sys-tem, you let your customersknow that reliability andsafety are among your top priorities.
Minimax has over 100 years ofexperience in the development,production, installation and main-tenance of fire protection solutions.Its high-quality products are beingcontinuously developed and improved to suit customers needs.
PRODUCTI EXTINGUISHING WITH WATER SPRAY.
Minimax water spray systemsare used to protect rooms andobjects and are suitable forindoor and outdoor installati-on. Water spray systems arethe preferred solution for theprotection of objects requiring
preventive cooling or quickfire suppression, such as:
Oil refineriesFuel tanksTransformersFacades
Cable channelsRecycling plants Waste incineratorsPaint shopsTheatres
The profound knowledge andcorrect application of relevantguidelines, the use of theapproved products as well asqualified personell for designand installation guaranteeyour safety.
APPLICATIONFAST RESPONSE EFFECTIVE FIRE FIGHTING.
Minimax water spray systemshave a number of distinctadvantages:
Extinguishes fires quicklyand prevents fires fromspreading over a largearea.Minimises the damage caused by fire and reducesdowntimes, protects thefuture of your business.
Reduces fumes and bindscontaminants in the waterspray. Allows large open areasand thus a more flexibleuse of the premises.Uses water, a natural fire-extinguishing agent that isavailable in unlimitedquantities at a very lowprice.
After a fire, the Minimaxwater spray system isquickly restored to readymode.

All sections of the buildingthat are to be protected areequipped with a pipe systemwith open extinguishing noz-zles. In ready mode, all pipingup to the deluge valve is filled with water. The systemincludes fire detectors ele-ments which, depending onthe site conditions and the
risk, are operated electrically,pneumatically, hydraulically ormanually. As soon as a fire isdetected, the deluge valves areopened. The water is sprayedonto the area from all noz-zles, extinguishing flames andabsorbing heat and coolingthe material on fire. Minimaxwater spray systems with
electronic control can be stopped manually by means of remote control (optional)so that the water flow can bestopped as soon a the fire isextinguished, preventingunnecessary damage.

FUNCTIONI WATER SPRAY EXTINGUISHING SYSTEMS
Deluge valve sets are used in extin-guishing systems where pipeworkswith open nozzles are a must. Theiruse is always advisable where waterneeds to be discharged in largerareas via an appropriate number ofnozzles.
Simultaneously for activation, an acoustic alarm is set off by ahydraulically operated alarm gong,and an electric alarm is transmittedto a permanently manned location(e.g. fire brigade). The deluge valveset can be activated either electri-cally, pneumatically or hydraulically.An additional manual release is also provided.
+ Pre-assembled trimming guarantees fast installation
+ Low weight
+ Compact design reduces the space required
+ Corrosion-resistant internal parts
+ High permissible operating pressure: 16 bar
+ Reduced pressure loss
+ No water hammer due to a cushioned closing action
+ Suitable for high flow rates
+ Functional and pressure tests of the valve set conducted by the manufacturer
+ Remote panel for the manual controlof the deluge valve set with electricrelease available
+ Optionally available external ope rat ing unit for manual remote-controlled re-setting of the delugevalve set with electric activation.
+ VdS-Approval
+ FM-Approval

Technical data
Electric activation with impulse valveThe electric activation of the deluge valve set is accom-plished by means of a detection system, which triggersthe solenoid valve in the event of fire. The solenoid valveopens, the pressure in the deluge valve control chamberdrops and the nozzle pipe work will be flooded.
In the event of fire, an electric alarm is released andtransmitted to a permanently manned location. In additi-on an acoustic alarm is released by means of an alarmgong. This applies to all activation modes.
In addition, Minimax offers an external panel that enables the manual activation of the Minimax delugevalve set from a remote location.
It can be used for the following tasks:
• Activation of the extinguishing process
• Minimisation of water damage through interruption of the water supply
• Easy and repeated reactivation if required
• Recommissioning of the deluge valve set which guarantees continuous protection
Hydraulic activationAs far as the hydraulic activation is concerned, the pilotline is directly connected to the control chamber of thedeluge valve. The system pressure of the water supply ispermanently applied to the pilot line. Should a pilotsprinkler release, the pressure in the control chamberdrops and the deluge valve opens.
Pneumatic activationThe pneumatic activation of the deluge valve set isaccomplished via a pilot line filled with compressed airand equipped with sprinklers or special heat sensors. In order to avoid a nuisance activation, the pilot lineoperating pressure is maintained by means of an auto-matic compressed air replenishment system. A diaphragmvalve is positioned between the pneumatic pilot line andthe control chamber of the deluge valve. If one of thesprinklers or heat sensors release, the pressure in thepilot line drops and opens the diaphragm valve. This cau-ses a pressure release in the deluge valve control cham-ber, the valve opens and water flows into the nozzle pipe work.
The deluge valve set with pneumatic activation is par ticularly suitable for areas exposed to frost.
