Bearings for Heat Recovery Units (Rotary Heat Exchangers)
Industrial heat recovery units, especially those equipped with rotary heat exchangers (also called rotary wheels or thermal wheels), rely on high-quality bearings to ensure continuous, efficient, and silent operation. These systems work in demanding environments where durability, precision and resistance to temperature fluctuations are essential.
Why bearings in heat recovery units are critical
The rotary wheel inside the recovery unit rotates at a steady speed, often operating 24/7. Any failure in the bearing assembly leads to increased energy consumption, uneven rotation, noise, vibration, and in many cases a complete system shutdown. This makes the correct choice of bearings a key factor in system reliability.
Typical bearing types used
- Deep groove ball bearings – for stable, low-noise rotation.
- Sealed bearings (2RS / 2Z) – protection against dust and humidity.
- High-temperature bearings – when the exchanger runs in elevated thermal conditions.
- Corrosion-resistant bearings – stainless steel variants for humid or chemically exposed environments.
- Custom bearing units and housings – for large industrial systems.
Main advantages of proper bearing selection
- Longer service life of the rotary wheel
- Smoother and quieter operation of the HVAC system
- Lower energy consumption
- Reduced downtime and maintenance costs
- Higher overall efficiency of the heat recovery process
