The RL3000-CHI Rapid Auto Roll Door from DMF International is engineered for coolrooms, chillers, and temperature-controlled environments where energy efficiency and climate stability are essential. Designed to minimise refrigerated air loss, this high-speed insulated door helps maintain internal temperatures while supporting efficient workflow and operational safety. 

With opening speeds of up to 1.5 metres per second, the RL3000-CHI enables fast access for warehouses, food processing facilities, and cold storage operations. The system is powered by DMF International’s advanced control platform featuring an easy-to-use LCD display interface. The controller is compatible with multiple activation methods, including motion sensors, floor induction loops, and remote-control access systems.

Built to perform reliably in demanding cold-room conditions, the RL3000-CHI incorporates a durable Polyskin insulated curtain with integrated foam to improve thermal retention and reduce energy costs. Reinforced aluminium wind bars enhance structural strength and stability, while an optional full-width clear vision panel improves visibility and supports safer two-way traffic movement. 

Developed from the proven RL3000 high-speed door platform, the CHILL Series delivers enhanced insulation performance together with improved noise reduction, making it an effective solution for temperature-sensitive industrial applications.
