Energy Recovery Wheel 4” for High Performance ERV Systems

- Unbeatable advantages
  - Direct replacement of the most common industry-standard sizes.
  - Monolith wheels are made using patented foil forming technology that mechanically interlocks foil layers together without any segments.
  - The double peripheral sealing system ensures no bypass and thus creates around 2% higher energy recovery whilst maintaining very low leakage (EATR).
  - Available AC motors options: 208-230/380/460V/3, 575V/3, 230/400V/3
  - 3A molecular sieve coated.
  - Side by side solution up to SF-54

Boost Your AHU with Energy Recovery Wheel

Swiss Rotors energy recovery wheels (rotor) are regenerative air-to-air energy recovery parts of the air handling unit. The main function of regenerative air-to-air rotors is the transfer of sensible (temperature) and latent (humidity) energy between exhaust and supply airflows. Regenerative rotors are important for energy conservation in ventilation systems that treat outside air in order to ensure good, clean air in your internal environments.

- Technical data
  - Ultra-low pressure loss with optimal effectiveness (4” depth) makes it ideal wheel for most applications.
  - Ideal for rooftop application and comfort clima, due to low-pressure loss.
  - Direct replacement for most typically used polymer wheels.
  - Wheel diameters: 21”-83”.
  - Airflow ranges: from 230 – 18 000 CFM.
  - Only monolith aluminum wheel structures, without segments to ensure unconstrained airflow.

Sorption / total
Both foil layers desiccant coated, high latent recovery efficiency and hygienic quality of the device is ensured by sorption material (3A molecular sieve).
Enthalpy / Hygroscopic
Mixture of media types: one foil is desiccant coated and the other in standard aluminum providing moderate latent heat recovery at a cost-conscious price.
Condensation / non-hygroscopic
No desiccant to recover moisture from exhaust air (sensible heat recovery only).

- How it works
  
  In energy recovery wheels (rotors), exhaust air and supply air passes the wheel matrix in the opposite direction. The energy from the exhaust air is then transferred to the supply air through the wheel matrix. Thanks to the alternating airflow direction, the wheel is self-cleaning and frost resistant at low temperatures.
