How to Choose the Right Cabinet-Type Heptafluoropropane System

　　Today, we'll show you how to distinguish between cabinet-type heptafluoropropane systems, along with the different styles of cabinet-type heptafluoropropane and the appropriate locations for their use.

　　The cabinet-type heptafluoropropane fire suppression system integrates components such as the extinguishing agent storage container assembly, jet piping, nozzles, and electromagnetic actuation devices. It is connected to an automatic fire alarm control panel, enabling autonomous detection and immediate fire suppression. Since the extinguishing agent cylinders are housed within the cabinet, different single-cylinder units of varying capacities can be selected to suit small-scale protection zones of different sizes, thereby minimizing the floor space required. Additionally, the nozzles feature a multi-orifice design, ensuring that the extinguishing agent rapidly and evenly fills the entire protected area. Like suspended fire suppression systems, this device also boasts convenient installation, simple construction, and low project investment—factors that make it highly popular among customers in practical applications.

　　We know that different protected areas require varying design concentrations. For instance, in archival spaces, the concentration is set at 10%, meaning 0.81 kg of HFC-227ea agent is needed per square meter. In addition to this, it’s also essential to calculate an appropriate reserve quantity. Some customers first determine the total agent dosage based on the volume of the protected area and then independently select the most suitable equipment. However, this process can sometimes lead to "choice paralysis," especially when considering cabinet-type HFC-227ea fire suppression systems, which come in four distinct configurations: single-cabinet with one nozzle, single-cabinet with two nozzles, dual-cabinet with one nozzle, and dual-cabinet with two nozzles. Meanwhile, the cylinder capacities themselves are available in seven standard sizes: 40L, 70L, 90L, 100L, 120L, 150L, and 180L.

　　All four plans can meet the total dosage requirement for the protected area, but selecting the most suitable one requires considering the specific conditions within the protected zone.

　　For example, in areas with many protected devices where space for cabinet-type heptafluoropropane fire suppression systems is limited, choosing a solution that uses fewer fire suppression units would clearly be more suitable. Conversely, if there are fewer devices—though they’re spread out more widely—opting for multiple fire suppression units would better ensure the safety of the equipment.

　　Additionally, the cabinet-type heptafluoropropane fire suppression system has a required safety distance for its operating surface—specifically, the distance from the operating surface to the wall or between two operating surfaces should not be less than 1 meter. Therefore, this is also an important factor to consider when selecting a solution.
