HIMA X-FAN 18 03 03993201813 Industrial Forced Air Cooling Fan Module

Product Brief Description

The HIMA X-FAN 18 03 (corresponding part number 03993201813, also referenced as 993201813) is an original German-manufactured industrial-grade forced air cooling fan purpose-built for the HIMA HIMax series 18-slot redundant power system baseplate X-Base Plate 18 01. As the core heat dissipation component of the HIMA safety control system, it maintains the long-term stable operating temperature for all high-power safety modules in the 18-slot rack, preventing performance degradation caused by overheating even in high-temperature heavy industrial environments, and ensuring the 24/7 uninterrupted operation of the safety instrumented system (SIS).

Core Technical Specifications

• Matching Platform: Dedicated for HIMA X-Base Plate 18 01 18-slot redundant power baseplate, 4 units are used in parallel in a single system rack to form a full-coverage heat dissipation airflow path
• Power Supply: 220V AC single-phase industrial power supply, fully compatible with standard industrial on-site power supply systems
• Air Volume: About 300 m³/h per unit, efficiently taking away the heat generated by 18 full-load working modules in the rack
• Noise Level: ≤ 45 dB(A), low-noise optimized design that will not cause noise interference to on-duty operators in the control room
• Protection Rating: IP54, with excellent dust-proof and splash-proof capability, adapting to harsh industrial sites with dust and water splash risks
• Structure Material: Corrosion-resistant metal housing, suitable for high-corrosion industrial environments in chemical, petrochemical and other industries

Key Product Features

• Adopts optimized high-efficiency fan blade design, which achieves excellent heat dissipation performance while significantly reducing operating noise, greatly improving the comfort of the on-duty operation environment in the control room
• Industrial-grade long-life bearing structure design, with a service life of up to 60,000 hours, supporting long-term uninterrupted operation of 7×24 hours
• Standard modular hot-swap design, supporting tool-free quick disassembly and replacement, allowing on-site maintenance without shutting down the running safety system
• Built-in fan working state detection function, which can upload operating status and fault alarm information to the HIMA Safety Suite system software in real time, supporting remote monitoring of heat dissipation system health
• Fully matches the installation size of the X-Base Plate 18 01 18-slot baseplate, no additional structural modification is required during installation, and it can be directly locked to the reserved fan installation position on the baseplate

Common Application Scenarios

• Heat dissipation support for ESD emergency shutdown systems in petrochemical refining facilities
• Temperature control for boiler MFT protection system racks in thermal power plants and nuclear power stations
• Heat dissipation management for HIPPS high integrity pressure protection systems of natural gas long-distance transmission pipelines
• Cooling support for F&G fire and gas monitoring system cabinets in hazardous chemical production workshops
• System supporting for new construction and renovation projects of HIMax 18-slot safety control racks in industries such as metallurgy, pharmaceutical manufacturing and rail transit signal control

Installation and Maintenance Guidelines

• Before installation, confirm that the fan rotation direction matches the airflow design requirements of the system rack, and the air inlet and outlet are not blocked by sundries to ensure smooth airflow
• Regularly clean the dust accumulated on the fan blades and filter screen, avoid long-term operation under high dust environment leading to reduced airflow and heat dissipation performance degradation
• Regularly check the fan operating status indicator lights in the system software, and replace the faulty unit in time when a fault alarm is triggered, and the other 3 fans can still maintain sufficient heat dissipation capacity in the short term
• The ambient temperature inside the control cabinet should be controlled below 40°C, to ensure that the fan can continuously and efficiently provide sufficient cooling air volume for the safety modules
