Most engineers don't think about a fan until it fails. And when it does - in the middle of a heatwave, on a rooftop unit running 24/7, or inside a cooling system where downtime costs thousands per hour - the spec sheet they chose from suddenly matters a lot. That's the problem we set out to solve at Hidria. Not just build a bigger fan. Build one smart enough to tell you when something's wrong before it fails, quiet enough not to fight your acoustic specs, and efficient enough to justify the upgrade on energy costs alone. The all-new 860mm and 960mm are the result of that thinking.

And if you're already running 800mm or 910mm units: the 860mm and 960mm keep the same mounting footprint. More airflow, more efficiency - no redesign on your end. What sets BIG-R apart isn't just raw performance. It's the modular electronics design that allows on-site component replacement without pulling the fan from the system - reducing maintenance costs by up to 90%. There's also a 3-axis accelerometer built in. It detects resonance peaks during operation and automatically bypasses critical speeds. Less mechanical stress. Lower noise. Longer life. We've already deployed this in an EV production facility running 38 fans, with live Grafana monitoring across all axes. This is what 26 years of fan engineering looks like when you stop iterating and start building the platform you actually want. Curious what the 860 or 960 would do in your application?
