DAOU ventilation heat exchanger DO7500 is used to discharge the exhaust air in the chick farm and keep the heat from loss at the same time.

    It can provide cleaner air for poultry houses and chick farms.

    The heat recovery rate can reach 60%~80%.

    The ventilation volume is 7500m³/h.

DO7500 Air Exchanger Functions

  1. Energy-saving
    This air exchanger uses advanced EC fans, which only consume small electricity.
  2. Average ventilation
    Through windbags, the exchanged new air could go inside every corner of chick farms.
  3. Avoid cold stimulation
    The exchanger could keep the heated temperature of new air and reduce the possibility of diseases.
  4. Improving production
    The heat exchanger could increase the temperature by 5~10℃ on the farm, making it easier to keep warm, and improving egg production.

Advantages of exchanger

  • Heat conduct principle

It exchanges the new air of low temperature, with the exhaust air of high temperature. So the new air goes inside farms with heat kept.

  • Heat exchange core

The equipment works with high efficient exchange core, which is a patent of DAOU company.

  • France technology support
  • DO2000 environmental controller
