The Quiet Revolution: How Next-Gen Silicone Fluid Cuts Fan Noise by 40% and Extends Service Life by 30%

As NVH (Noise, Vibration, and Harshness) standards for commercial vehicles become increasingly stringent, our lab's breakthrough NX-7 silicone fluid formula is redefining fan clutch performance benchmarks. This third-generation composite fluid technology not only reduces operational noise by 40% but also extends average service life to 240,000 km.

• Addition of nanoscale polymer microspheres reduces viscosity fluctuation under high-speed shear

• New oxidation stabilizers increase fluid temperature resistance from 180°C to 210°C

• Intelligent viscosity curve design enables smoother engagement, reducing impact noise

In comparative tests with Dongfeng Tianlong heavy-duty trucks (fully loaded at 49 tons, continuous hill climb conditions):

• Traditional product: In-cab noise peaked at 78 dB, with significant fluid degradation after 150,000 km

• NX-7 formula: Noise remained stable below 71 dB, with only 12% performance degradation after 200,000 km

Smoother engagement characteristics reduce engine power fluctuation by 3-5 HP, saving approximately 180 liters of fuel annually per vehicle. Furthermore, the extended replacement interval means 1.5 kg less waste silicone fluid requires disposal per vehicle each year.

This technology has already received OEM certification from FAW Jiefang and Sinotruk, with full aftermarket availability expected in the second half of 2024.
