Technical Parameters and Structural Design
Fan Configuration: Equipped with 2 axial fans and adopting a redundant power supply design, it ensures the heat dissipation function remains operational even when a single power supply path fails. This prevents heat dissipation breakdown caused by power interruption, and keeps the operating temperature of core system components (such as CPU modules and I/O modules) within a safe range.
Monitoring Function: Integrated with voltage monitoring and fan operation status monitoring functions, it can provide real-time feedback on power supply stability and fan working conditions. This enables operation and maintenance personnel to detect abnormalities promptly, reduces the risk of system shutdown caused by heat dissipation failures, and meets the core requirement for monitorability of industrial safety systems.
System Compatibility: As a dedicated accessory for the HIQuad X system, it is fully compatible with the system’s F-BASE RACK series racks (including 19-inch standard base racks and expansion racks). It can be seamlessly integrated into the overall architecture of the HIQuad X safety control system without the need for additional adaptation or modification.
Product Correlation and Certification Compliance
Product Code Correspondence: The product code specified in the document is K9202B, which is an alternative identification form for the model 996920261. Both refer to this 2-axial-fan redundant heat dissipation unit. Its technical specifications are identical to those of the K9203A (3-axial-fan version) except for the number of fans, with differences only in heat dissipation power and the intensity of heat dissipation requirements for applicable scenarios. Users can select the appropriate model flexibly based on the module density of the rack.
Certification Standards: It has obtained certification in accordance with the DNV GL Classification Rules along with the HIQuad X system, complying with the installation requirements for ships, offshore installations, and high-speed lightweight craft. It is suitable for temperature class B (0°C and above), and meets specific humidity, vibration, and Electromagnetic Compatibility (EMC) standards. Installation must comply with the protection level requirements specified in the DNV rules.
Application Restrictions: It must be used in conjunction with other certified components of the HIQuad X system, and is only applicable for internal heat dissipation of system racks. It shall not be used in other non-certified systems or scenarios. In addition, the installation environment must meet the stringent requirements of industrial-grade safety control scenarios to avoid the impact of extreme environments on the operational stability of the fans.
Application Scenarios and Core Value
Application Scenarios: It is mainly used for heat dissipation of HIQuad X safety system racks. This system is widely applied in safety-critical control and critical control applications (such as ship power system control, offshore platform safety monitoring, etc.). The K9202B fan ensures the performance stability of the system under high-load and long-term operation through stable heat dissipation, and indirectly supports the realization of SIL 3 safety-related functions.
Core Value: The combination of industrial-grade redundant design and monitoring functions endows it with strong anti-interference capability in harsh environments such as marine and offshore engineering (high vibration, humidity fluctuation, unstable power supply). It can effectively extend the service life of the HIQuad X system, reduce the probability of module failures caused by overheating, provide continuous and reliable heat dissipation guarantee for safety-critical control scenarios, and serve as an important auxiliary component for the long-term stable operation of the system.
Installation and Operation Requirements
Installation must strictly comply with the rack assembly specifications of the HIQuad X system to ensure mechanical compatibility with the rack and stability of electrical connections. Redundant power supply circuits shall be deployed in accordance with the system wiring standards to prevent improper wiring from affecting monitoring functions and redundant performance.
In conjunction with the periodic assessment requirements of the system, the product shall undergo factory sample random inspection as well as production and inspection process audit during the periodic assessments conducted every 2 years and 3.5 years. This is to ensure that there are no changes in product design, materials and performance, and to maintain certification compliance.
No additional software configuration is required, but its operation status monitoring data can be viewed via SILworX (Version 12.28 and compatible versions), the programming and configuration tool of the HIQuad X system, facilitating integration into the overall system operation and maintenance management system.
