Dry System features ①. Dry system, water in the pipe network after the alarm valve, it is possible to avoid the danger of freezing and moisture constraints from the ambient temperature can be used in some places can not use a wet system. ②. Higher than the wet system investments. Inflatable because of the need to increase the set of inflatable equipment and increase the system cost. ③. Construction and maintenance management dry system is more complex, fm certification fire sprinklers, air tightness of the pipeline have more stringent requirements, usually pipe pressure should be maintained at a certain range, Hunan fm certified fire sprinklers, when the pressure drops to a certain value, Shandong fm certified fire sprinklers, we need to be inflated. ④. Sprinkler slower than a wet system, because the nozzle heating is turned on, first to exhaust the gas pipeline, Chongqing fm certified fire sprinklers, and then the water, which delayed the time. To fire sprinkler systems in a thermally sensitive element sensitivity of rapid response in the initial fire started just few heads, it is possible to have enough water to extinguish the fire quickly action or inhibit the spread of fire sprinklers, fast thermal response time, spray water flow characteristics, mainly for heat-sensitive element overhead warehouse and logistics company warehouse sprinkler system. fm certification Fire sprinklers | Year Anyuan Electromechanical | Hunan fm certified fire sprinklers by the Hubei Chong Anyuan Electrical Equipment Co., Ltd. to provide. fm certification Fire sprinklers | Year Anyuan Electromechanical | fm certified fire sprinklers Hunan, Hubei Chong Anyuan Electrical Equipment Co., Ltd. (www.hbcay119.com) (www.hbcay119.com) this year introduced a new upgrade, the above picture is for reference Please call the telephone or pictures on this page, for the latest information, contact: Liu law.
