Why is a spark ex­tin­guish­ing sys­tem im­port­ant?

The Mini­fog Eco­n­Aqua water mist ex­tin­guish­ing sys­tem of­fers par­tic­u­larly ef­fi­cient build­ing pro­tec­tion through the use of in­nov­at­ive low-pres­sure water mist tech­no­logy. Com­pared to con­ven­tional sprink­ler sys­tems, the Eco­n­Aqua sys­tem uses up to 85 per­cent less ex­tin­guish­ing water, re­du­cing po­ten­tial water dam­age to a min­imum. The Eco­n­Aqua con­trol panel can also be de­signed much more com­pactly than a clas­sic sprink­ler sys­tem. This saves space and on-site costs and makes the Mini­fog Eco­n­Aqua water mist ex­tin­guish­ing sys­tem ideal for ret­ro­fit­ting in ex­ist­ing build­ings. A po­ten­tial dis­aster of this mag­nitude is best handled with pre­vent­at­ive meas­ures that are im­me­di­ate, ef­fect­ive and de­pend­able. With the Minimax sys­tem sparks can be de­tec­ted and ex­tin­guished prior to reach­ing the fil­ter or dust col­lector thereby pro­tect­ing all com­pany as­sets. Minimax is a pi­on­eer in the de­vel­op­ment of spark ex­tin­guish­ing sys­tems. Minimax of­fers spark sup­pres­sion sys­tems with VdS ap­proval. Its pro­tec­tion strategy has been suc­cess­fully tried and tested in thou­sands of ap­plic­a­tions world­wide.

Ad­vant­ages at a glance

Spark ex­tin­guish­ing sys­tems de­tect ini­tial ig­ni­tion in suc­tion and con­vey­ing sys­tems and pro­duce an in­stant water cur­tain via auto­matic ex­tin­guish­ing fea­ture in order to smother smol­der­ing particles. These sys­tems are re­com­men­ded for use in areas where com­bust­ible ma­ter­i­als are pneu­mat­ic­ally trans­por­ted and where there is a high risk of fires or dust ex­plo­sions due to spark­ing or smol­der­ing particles. As a rule, the ex­tin­guish­ing pro­cess oc­curs without in­ter­rupt­ing op­er­a­tions.

• Re­sponse time: There are just mil­li­seconds between spark de­tec­tion and es­tab­lish­ment of a com­plete water screen in the trans­port pipe. The re­sponse time is sig­ni­fic­antly re­duced com­pared to con­ven­tional spark sup­pres­sion sys­tems.
• Dis­tance between spark de­tector and ex­tin­guish­ing unit: Thanks to the rapid re­sponse time, the dis­tance re­quired between spark de­tector and ex­tin­guish­ing unit is sig­ni­fic­antly shortened. There­fore plant areas with short con­veyor dis­tances can also be pro­tec­ted with Minimax spark sup­pres­sion sys­tems.
• Vis­ib­il­ity mon­it­or­ing: This en­ables a tar­geted main­ten­ance of the sensors. By identi­fy­ing the level of pol­lu­tion, the risk in the rel­ev­ant pipe can be de­tec­ted in good time.
• In­stall­a­tion time: In order to min­im­ize in­stall­a­tion times, rapid as­sembly kits are used for the de­tect­ors and ex­tin­guish­ing nozzles.
• VdS- and FM-ap­proved sys­tem: Minimax of­fers spark sup­pres­sion sys­tems with VdS ap­proval and also with FM sys­tem ap­proval.

Func­tion

A fully auto­matic spark ex­tin­guish­ing sys­tem con­sists of spark de­tect­ors, a con­trol panel and an auto­matic ex­tin­guish­ing unit. Sparks trav­el­ling through the duct of the con­vey­ing sys­tem are in­stantly iden­ti­fied by the in­frared spark de­tect­ors moun­ted flush to the wall of the duct. The spark de­tector sends a sig­nal to the con­trol panel which then trig­gers the solen­oid valve of the auto­matic ex­tin­guish­ing unit, while sim­ul­tan­eously ac­tiv­at­ing an aud­ible alarm. The ex­tin­guish­ing water is re­leased after mil­li­seconds and in­jec­ted into the duct via the stra­tegic­ally placed and pat­en­ted flat spray nozzles cre­at­ing a wall of water cov­er­ing the en­tire cross sec­tion. The glow­ing particles are con­veyed into the water spray cur­tain. Im­me­di­ately af­ter­wards the solen­oid valve closes auto­mat­ic­ally. The com­plete de­tec­tion and ex­tin­guish­ing pro­cess nor­mally op­er­ates dur­ing pro­duc­tion in order to elim­in­ate ex­pens­ive down­times. De­pend­ing on the amount of po­ten­tial ig­ni­tion sources it is also pos­sible to have the con­vey­ing ma­chine auto­mat­ic­ally shut down.
