 MOSAFE HFC-227ea Engineered Fire Extinguishing System MOSAFE HFC-227ea is a clean,safe fire-fighting agent for use in total flooding automatic extinguishing systems. MOSAFE HFC-227ea is rated as Zero Ozone Depletion(ODP),is electrically non-conductive,clean,and leaves no residue. MOSAFE HFC-227ea extinguishing systems are "engieered". Engineered systems for example can consist of several HFC-227ea containers,manifolded together and connected viaa pipe net work to a number of discharge nozzles. System may be activated mechanically or electrically.Mechanical manual actuation is via a handle attahced to the container valve.Electrical actuation is via a removable solenoid actuator.The solenoid actuator can be energised automatically by a signal from a fire detection and alarm control panel. Approvals And Standards MOSAFE manufactured clean agent system equipments and the HFC-227ea agent,have acquired comprehensive approvals and listing s providing futher support to the overall product. HFC-227ea Agent. Underwriters Laboratories Inc. (UL) Recognised Component NFPA 2001 Clean Agent Fire Extinguishing System(Listed Alternative) MOSAFE Manufactured Systems Underwriters Laboratories Inc. (UL Listed) MOSAFE HFC-227ea Extinguishing Systems are to be designed,installed,inspected,maintained,tested and recharged by qualified,trained personnel in accordance with NFPA2001,Standard on Clean Agent Fire Extinguishing Systems,and to be used in accordance with Environmental Protection Agency(EPA) Significant New Alternatives Program (SNAP) HFC-227ea Agent Characteristics HFC-227ea is a clean,gaseous agent containing no particles or oily residues. It is produced under ISO9002 guidelines to strict manufacturing specifications ensuring product purity.HFC-227ea leaves no residue or oily deposits on delicate electronic equipment,and can be removed from the protected space by ventilation. HFC-227ea is thermally and chemically stable,but without the extremely long atmospheric lifetimes associated with other proposed halon replacements. HFC-227ea systems are suitable for us in normal commercial and industrial environment.Typical areas that can be protected by an HFC-227ea system are detailed below;the list is by no means exhaustive. ◇Bank Vaults ◇Libraries ◇Rare Book Stores ◇Electronic Data Processing ◇Telephone Exchanges Studios ◇Commumnication Centre ◇Transformer and Switch rooms ◇Control Rooms ◇Test Laboratories ◇Flammable Liquid Stores Complete suppression using HFC-227ea has the following advantages: The low concentration of HFC-227ea required means less visual obscurity and minimal risk to personnel. The small quantity of agent discharged minimised over-pressurisation of the protected area. Maximum safety for personnel due to low toxicity. Most effective when used with automatic detection to introduce HFC-227ea with a 10 second discharge. The ability to prevent re-ianition as long as concentration levels are maintained. Two kinds of working pressure system are available(25bar/360psi and 42bar/600psi),make the system has superior economy. MOSAFE System Component  A typical manifold system of MOSAFE HFC-227ea gas fire extinguishing system includes the cylinder kit,manual release device,pilot hose,discharge hose,check valve,manifold,relief device of distributor manifold,direction valve,pressure operating switch,pipe ware and nozzle which connected to the automatic fire alarm system. Some items are optional depending on the application Technical Information The 40,50,60,70,80,90,100,120,150 and 180L containers are manufactured in accordance with TPED  HFC-227ea Container The agent storage vessel consists of a container fitted with a valve and internal syphon tube,factory filled with HFC-227ea,and super-pressurised with dry nitroen to 25bar @ 21℃（360psi @ 70°F）and 42bar @ 21℃（600psi @ 70°F）. Containers sharing the same manifold shall be equal in size and fill density. Containers are finished in red and are available in various sizes. A nameplate is adhered to the container displaying the agent weight,tare weight,gross weight,fill density and charge date. Container Details   System Design Procedure The following procedure must be followed when designing HFC-227ea system. Determine hazard material and required design concentration. Identify individual enclosure volumes and deduct any impermeable volumes where Appropriate Determine hazaed altitude and correction factor. Calculate quantity of HFC-227ea per enclosure,at minimum design temperature. Determine container size and fill density. Select nozzle type and location Design pipe network. Calculate quantity of HFC-227ea per nozzle. Check percentage agent split at tee's. Identify all pipe lengths,rises,falls and nozzle reference numbers. Engineered Systems Flow Calculation MOSAFE Engineered systems are based on special hydraulic flow program-MOSAFE Protection Flow Calculation Software.The sofeware predicts the two phase flow of HFC-227ea and nitrogen through a pipe net work.Information detailing the enclosure is entered and the program calculated the required pipe sizes,nozle drill sizes,average nozzle pressures and discarge time.The software calculation results are in accordance with the actual situation. As system design calculations are critical to the success of the extinguishing system,only MOSAFE trained personnel are permitted to perform system calculations. If in the future,companies other than MOSAFE wish to use the program,represnetatives will be required to attend a formal training session.All system calculations are conducted either"in house" by MOSAFE or authorised suppliers.
