Material thickness: 3 mm
Material: Galvanised steel sheet
Profile structure: U-channel body with a pressed-on toothed profile
Surface finish: Hot-dip galvanised — resistant to moisture and outdoor conditions
Installation: Perforated mounting points for fixing to the curtain shaft
Application: Greenhouse thermal curtain (thermal screen) systems, energy curtain drive lines
This rack is the transmission element of the gear-rack set that facilitates power transmission in the motorised drive mechanism of heat curtain (thermal screen) systems, which are used to reduce heat loss in greenhouse operations. The 3mm material thickness, which is thicker than that of standard ventilation racks, provides additional strength against the higher tensile loads encountered in heat curtain systems. The hot-dip galvanised coating provides long-lasting protection against humidity and condensation in the greenhouse environment. The U-channel housing design offers ease of installation, whilst the precision-engineered tooth geometry ensures smooth, low-wear operation with the drive pinion. It is a reliable drive component for modern greenhouse facilities designed to maximise energy efficiency.
