The panel door system is mounted inside of cooling pad opening. It’s closed for heat preserving in winter and opened to adjust the ventilation opening amount and fresh air flow in hot seasons during tunnel ventilation.
Benefits:
- Better control the fresh air flow direction
- Clear the ventilation dead angle around the cooling pad during tunnel ventilation
- 3 layer insulation panels (FRP+PS+FRP), nice heat insulation effect
- Continuous EPDM foam sealing strip, strong sealing performance
- Specially designed reinforcing ribs to prevent panel door from deformation and bad sealing caused by it.
- Each reinforcing rib is mounted with an adjustable pull arm, which serves to shut the panel door tightly with only a little strength.
- The opening amount can be easily adjusted by the climate controller
- Insulation performance is 8 times of the regular rolling curtain when completely closed in winter, saving 15% of the heating costs compared with a regular rolling curtain.
