TUNNEL
DRIERS

Tunnel Driers manufactured by us are Counter current, Pressurised and High Production systems. Developed in late 2005, these have been the bedrock for many a industries.

Hot Air Tunnel Drier Working Concept

The Tunnel driers are designed as Counter Current - Step and Repeat Drying systems. The hot air and the wet material move counter-current resulting in the desired quality product in much lesser time and at relatively lower costs as compared to other drying systems.

Tunnel Drier Salient Features

  • High Production Drying systems with Step and Repeat movement inside the Tunnel.
  • Counter Current direction of material movement and air flow enable much higher efficiencies ensuring our Tunnel Drier exhaust is not more than 4-5deg C above ambient.
  • Uniform drying due to movement of material from high moisture to very low moisture zones.
  • Fully automated system with PLC based controls, VFD controlled motors, Sensors and controllers to ensure appropriate functioning of the system.
  • Touchscreen HMI for operation control also aids in fault diagnostics thus making it simple and easy to operate.
  • High Production, Next to zero maintenance and ease of operations is what makes our Tunnel Drier a necessary Production Equipment in many an Industry.
