MK 15Fire Protection System

fire protection systemsa next generation technology

Nonpolluting AgentIn ZEROFIRE fire protection devices only Novec™ 1230 by3M™ is employed as extinguishing agent to providemaximum environmental tolerance.Due to its minimal toxicity it is a perfect substitute for Halonagents. Novec™ 1230 by 3M™is suitable as extinguishingagent for rooms occupied by human beings.

Plug and playEmployment of a ZEROFIRE fire protection system is kept assimple as can be. Easy installation is facilitated in directvicinity of the object to be protected. Optionally, the MK 15can be parameterized and monitored by our free of chargesoftware package ZEROFIRE Remote.

DependabilityFire protection systems by ZEROFIRE are flexible by designallowing the use of any smoke detection system available.The Extinguishing agent capacity is sufficient to givemaximum protection for objects up to 1,5m³.The patented deployment system vaporizes the agent andpermeates the object to be protected in shortest periods oftime.

CompactnessThe fire extinguishing system MK 15 by ZEROFIRE is anindependent, compact extinction device for fire fighting inclosed control cabinets, cabinet networks or 19” racks.Mounting options at the door or vertical surface reducingspace requirement to a minimum.

ScalabilitySpace requirements of electrical systems or 19” racks arediverse like their configurations. ZEROFIRE systems areperfectly adaptable providing unlimited scalability.Communication of all extinguishing agents in the network isestablished via a loop wiring system. Each device controlsand monitors all other devices alternatively.
