The HIMA K9202 is a high-performance integrated cabinet cooling fan designed specifically for safety-critical control systems in hazardous environments. As part of HIMA’s thermal management solutions, this ruggedized fan module ensures optimal operating temperatures for SIL3-certified safety controllers in the HIMax series. The K9202 features intelligent speed control with ±5% RPM accuracy, automatically adjusting airflow based on real-time cabinet temperature monitoring.
Engineered for continuous operation in demanding industrial settings, the K9202 maintains positive pressure in explosion-proof enclosures (Ex d IIB T4 certified) while consuming only 18W at full load. Its vibration-dampened design reduces acoustic noise to <35dB, making it suitable for noise-sensitive control rooms.

Key Features and Advantages:
Intelligent thermal management: The K9202’s embedded PID algorithm maintains cabinet temperature within ±1°C of setpoint, preventing component degradation. Its tachometer output provides real-time RPM monitoring for predictive maintenance.
Safety compliance: Explosion-proof construction meets ATEX/IECEx standards for Zone 1 hazardous areas. The brushless DC motor eliminates spark risk in petrochemical applications.
Durability: Military-grade bearings withstand 5G vibration (IEC 60068-2-6), ensuring reliability in offshore platforms. The corrosion-resistant housing survives salt spray tests per ISO 9227.
Application Areas:
- Oil & Gas: SIL3 safety systems in refinery process areas.
- Chemical: Batch reactor control cabinets.
- Power: Turbine emergency shutdown systems.
- Mining: Underground conveyor safety controls.
In pharmaceutical plants, the K9202’s stainless steel variants meet GMP cleanroom requirements.
