In the high-pressure world of fire suppression, the trigger is only as effective as the force behind it. The 120043 provides the calibrated 240-gram charge of compressed nitrogen needed to physically drive the system's mechanical levers, open agent cylinder valves, and actuate gas shutoff devices.\u003c\/p\u003e\n        \u003cp\u003eManufactured to meet stringent DOT and NFPA pressure vessel standards, this cartridge is the essential power source for commercial kitchen hoods. Its high-tensile steel construction and specialized soft-seat puncture seal ensure that the internal 2,000+ PSI charge remains stable for years of standby service, but releases instantaneously the moment the UCH's puncture pin strikes. For fire protection professionals, the 120043 is a mandatory component for maintaining factory-listed performance.\u003c\/p\u003e\n\n        \u003ch3\u003e240g Precision Mass\u003c\/h3\u003e\n        \u003cp\u003eThe 240g refers to the mass of compressed nitrogen stored within the vessel. This specific volume is mathematically weighted to provide enough expanded gas to pressurize the actuation tubing while maintaining the residual force needed to open agent tanks. Using a non-OEM or incorrectly sized cartridge can result in a partial discharge where the agent is never released, a critical failure point noted in fire suppression system auditing.\u003c\/p\u003e\n\n        \u003ch3\u003eBoyle's Law in Suppression\u003c\/h3\u003e\n        \u003cp\u003eAs the compressed nitrogen leaves the small volume of the cartridge and enters the larger volume of the actuation piping, it undergoes rapid expansion. This expansion creates the kinetic energy required to overcome the heavy-duty return springs in commercial gas valves. The 120043 ensures this expansion surge is sufficient across the entire length of the system's listed piping limits.\u003c\/p\u003e\n\n        \u003ch3\u003eHermetic Soft-Seat Sealing\u003c\/h3\u003e\n        \u003cp\u003eThe puncture end features a specialized alloy seal engineered for a clean, non-fragmenting puncture. Unlike generic cartridges that can shred metal into the valve, the OEM Range Guard seal ensures no debris enters the sensitive UCH orifices, preventing clogs that could lead to system failure liability.\u003c\/p\u003e\n\n        \u003ch3\u003eUL and FM Global Listing Continuity\u003c\/h3\u003e\n        \u003cp\u003eRange Guard systems are UL listed and FM approved as a complete assembly. Using refilled or third-party cartridges is a direct violation of these listings. The 120043 ensures your facility remains compliant with fire safety codes, protecting you from denied insurance claims due to non-standard components.\u003c\/p\u003e\n\n        \u003ch3\u003eWeight-Based Verification\u003c\/h3\u003e\n        \u003cp\u003eThe cartridge is labeled with a Gross Weight and Minimum Weight stamp. During semi-annual fire inspections, a technician simply weighs the unit on a calibrated scale. This is the most reliable method of ensuring system readiness without needing to discharge the unit.\u003c\/p\u003e\n\n        \u003ch3\u003eTemperature Stability\u003c\/h3\u003e\n        \u003cp\u003eKitchen hoods experience extreme thermal fluctuations. The 120043 is rated to maintain its internal pressure across the full ambient temperature range, ensuring that a hot kitchen does not lead to dangerous over-pressurization or a cold start failure.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 2: Applications \u0026 Use Cases --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eApplications \u0026amp; Use Cases\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003cul\u003e\n          \u003cli\u003e\n\u003cstrong\u003eHigh-Volume Fryer Batteries:\u003c\/strong\u003e Providing the pneumatic force needed to discharge wet chemical agents over deep-seated grease fires.\u003c\/li\u003e\n          \u003cli\u003e\n\u003cstrong\u003eInstitutional Cafeterias:\u003c\/strong\u003e Ensuring code-compliant safety in hospitals where safety audits are rigorous and public record.\u003c\/li\u003e\n          \u003cli\u003e\n\u003cstrong\u003eIndustrial Food Processing:\u003c\/strong\u003e Protecting massive oil reservoirs where the agent volume requires a high-pressure nitrogen propellant.\u003c\/li\u003e\n          \u003cli\u003e\n\u003cstrong\u003eUCH Retrofits:\u003c\/strong\u003e The standard replacement part for technicians converting older systems to the modern Universal Control Head platform.\u003c\/li\u003e\n          \u003cli\u003e\n\u003cstrong\u003eMechanical Gas Valve Actuation:\u003c\/strong\u003e Ensuring that automatic gas shutoff valves have enough force to trip during a discharge.\u003c\/li\u003e\n        \u003c\/ul\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 3: Technical Specifications --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eTechnical Specifications\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003ctable class=\"specs-table\"\u003e\n          \u003cthead\u003e\n            \u003ctr\u003e\n              \u003cth\u003eFeature\u003c\/th\u003e\n              \u003cth\u003eDetails\u003c\/th\u003e\n            \u003c\/tr\u003e\n          \u003c\/thead\u003e\n          \u003ctbody\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eManufacturer\u003c\/td\u003e\n              \u003ctd\u003eRange Guard (A Badger Fire Protection Brand)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003ePart Number\u003c\/td\u003e\n              \u003ctd\u003e120043\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eCartridge Mass\u003c\/td\u003e\n              \u003ctd\u003e240 Grams (Nitrogen)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eMaterial\u003c\/td\u003e\n              \u003ctd\u003eHigh-Tensile Forged Steel\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n              \u003ctd\u003eRange Guard UCH\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eCertification\u003c\/td\u003e\n              \u003ctd\u003eDOT Compliant \/ UL Listed\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eInspection Method\u003c\/td\u003e\n              \u003ctd\u003eWeight-Based Verification\u003c\/td\u003e\n            \u003c\/tr\u003e\n          \u003c\/tbody\u003e\n        \u003c\/table\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 4: Maintenance \u0026 Compliance --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eMaintenance \u0026amp; Compliance\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003ch3\u003eSemi-Annual Weight Check\u003c\/h3\u003e\n        \u003cp\u003eDuring the mandatory 6-month check, the cartridge must be weighed.
