Complete Coating Lines
Overview
Thermal Energy System covers the pretreatment, curing, thermal or heat-recovery stage of a coating line: Natural gas / biomass pellet / infrared radiation. Selected by part material, film thickness, output and local energy mix, and interlocked with the booth and conveyor on the same cycle.
Key Features
Natural gas heating system
Clean and efficient with low running cost, suited to sites with gas supply.
Biomass pellet heating system
Eco-friendly and energy-saving, using biomass pellets — suited to sites without gas supply.
Infrared radiation heating system
Fast heating and uniform temperature for processes with strict ramp requirements.
Ensures the furnace temperature curve
The thermal system supplies heat inside the line furnaces using diesel, gas, electricity, coal or biomass pellets, working with hot-air circulation to ensure the temperature curve.
Applications
- New powder or e-coating lines
- Capacity expansion and re-balancing of an existing line
- Emission compliance and energy-consumption upgrades
- Heat recovery and secondary-combustion retrofits
How It Works
A line is organised in four stages — pretreatment, spraying, curing, thermal. Pretreatment is chosen by part: spray, dip or tank immersion; the curing oven by site: straight-through, semi-bridge, bridge, conveyor or batch oven.
Thermal and heat recovery: natural gas, biomass pellets or infrared depending on local energy; the recovery stage uses secondary combustion and a heat exchanger to return oven exhaust heat to pretreatment drying.

FAQ
How is the capacity of a coating line determined?
Back-calculated from hanger density, conveyor speed and oven length. Pretreatment, booth and oven must share the same cycle, otherwise the oven becomes the bottleneck.
Which applications is the Thermal Energy System suitable for?
Natural gas / biomass pellet / infrared radiation. Suitable for complete lines combining pretreatment, coating, curing and thermal systems.
How long does customisation and delivery take?
Typically 25–40 days for a single machine and 60–90 days for a complete line, counted from process confirmation and sample approval.
