Product Overview
According to published performance data that is independently certified in accordance with ASHRAE 84-78P, the SEMCO True 3 Angstrom (True 3Å) total energy recovery wheel is far superior to all other air-to-air energy recovery systems. Its unique flute design coupled with numerous other design innovations provides for the highest possible heat transfer characteristics while simultaneously reducing pressure loss parameters. These combined features optimize the “sensible” (temperature) recovery portion of the wheel’s performance.
The True 3Å (TE3) molecular sieve desiccant coating provides “latent” (moisture) recovery efficiencies that match the improved sensible values. The transfer surface provides a rate of adsorption that is more than double that of other desiccants. The result is effective moisture transfer from the high velocity airstreams, which is essential to energy-recovery applications.
Key Features and Benefits
- Independently certified wheel performance: Equal latent and sensible heat transfer
- Laminar flow flute design: Low pressure drop with added benefit of being “self-cleaning”
- Split-frame options: Ensure even the biggest wheels can be shipped and installed when space restrictions exist
- Non-contact labyrinth seals: Indefinite life since the seals never actually touch the rotating surface
- Long-life, external, pillow block bearings: Can be maintained or replaced without removal of the rotor
- Multiple control options: Tailored controls for specific climate demands to maximize energy savings
- VFD-ready drive motor with integrated gearbox: Low operating cost with seamless integration to site’s building management system
- 13 standard sizes with custom, aftermarket size capabilities: Standard sizes to fit most new builds; retrofit options for existing unit upgrades
