Advantages
Why the 5L-45 works well for smaller matched dryer applications.
Compact matched solution
The source materials position the 5L-45 as the matched pellet furnace for Tongtai’s 35-ton newly developed batch dryer.
Clean indirect heating
Indirect hot-air heating helps support grain drying applications that need cleaner hot air and more stable temperature control.
Renewable pellet fuel
Biomass pellets support renewable and lower-carbon heating while keeping daily operation practical for small projects.
Key Features
Built for stable hot-air supply and practical operation in smaller drying projects.
Automatic Feeding
Automatic feeding supports easier daily operation and more stable fuel supply.
Intelligent Temperature Control
The control system adjusts operation to maintain the target hot-air temperature.
Indirect Hot-Air Delivery
The heat-exchange structure heats clean air before it is sent to the dryer or drying room.
Automatic Cleaning Support
Automatic cleaning with manual assistance helps improve routine operating convenience.
Pellet Fuel Compatibility
Suitable for biomass pellets including wood-based and husk-based pellets according to the source set.
Basic Safety Protection
The documented safety package includes over-temperature protection, leakage protection, and fault alarm.
Applications
Typical project scenarios where the 5L-45 is a practical fit.
Small Grain Dryers
Suitable for smaller matched dryer applications that need compact indirect-heating support.
Drying Rooms
Can be used for drying-room heating where clean hot air and practical automation are needed.
Paddy and Other Grains
Positioned for paddy and other grain drying projects requiring stable renewable-fuel hot air.
Smaller Rural Projects
Practical for customers who need a compact furnace without moving to a larger industrial configuration.
