Core Products
Perseus delivers high-performance cooling fans, intelligent fan-drive/control electronics, integrated thermal management modules, and rugged retention hardware. We provide drop-in replacement review and structural-thermal solutions to optimize SWaP in severe defense environments.
High-Performance Fans
Covering 30mm to 210mm in axial and centrifugal configurations, Our fans span an extensive standard range — with full custom engineering capability for platform-specific requirements. Every unit is designed for continuous operation from -55°C to +85°C and validated to MIL-STD-810 and MIL-STD-461.
Retention Hardware
3-segment and 5-segment wedge lock components for PCB module retention in defense chassis. The hardware combines thermal contact, repeatable locking force, and shock/vibration resistance for rugged electronics packaging.
Thermal Management Modules
Developed to ATR and MCU military standards in 3U and 6U form factors, supporting VPX, CPCI, and VME backplane configurations. Precision-engineered for conduction and convection cooling in high-stress environments.
Motors & Drives
Rugged fan-drive and control electronics for regulated airflow, telemetry, protection logic, and platform-defined power architectures. Developed for defense equipment and other demanding industrial applications where reliability and integration discipline matter.
Industry Solutions
Proven thermal management architectures for multi-domain defense platforms. We secure the operational reliability of advanced electronics against extreme altitude, temperature, and corrosive stress.
Military Aircraft Avionics Cooling
Engineered for the physics of flight. Our fans maintain consistent P-Q performance from sea level to 50,000+ feet. Validated for Rapid Decompression, Thermal Shock, and Acceleration (High-G) to ensure mission-critical reliability for avionics and UAV payloads.
