Commercial hubs usually operate between 0°C to 40°C. Industrial hubs often go to 55°C. Our Wide Temperature hubs are rated for -40°C to 85°C, using specialized components that won’t crack in extreme cold or leak in extreme heat.

Wide temperature USB hubs are built using automotive- and industrial-grade components rated for extreme operating environments. These parts are more costly to source and require additional design validation and testing to ensure long-term reliability.

No. Coolgear Wide Temp hubs use rugged metal chassis + an additional aluminum heat sink is mounted to the side of the hub, allowing for fanless operation which increases reliability in dusty or vibrating industrial settings.

Yes. All components are rated for immediate power-up at the lowest rated temperature without needing a pre-warming period.

Extreme heat can cause thermal throttling in consumer electronics. Our hubs are engineered with high-tolerance chipsets to maintain consistent 5Gbps or 10Gbps throughput even at the top of the temperature range.
