Complete Coating Lines
Overview
Waste Heat Utilization System covers the pretreatment, curing, thermal or heat-recovery stage of a coating line: Lower emissions · heat recovery · secondary combustion. Selected by part material, film thickness, output and local energy mix, and interlocked with the booth and conveyor on the same cycle.
Key Features
Reduces flue gas emission
Reduces the emission of flue gas and hot air into the atmosphere.
Effective heat recovery
Effectively collects waste heat for full utilization.
Secondary combustion
Secondary combustion technology achieves emission reduction and energy saving.
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 Waste Heat Utilization System suitable for?
Lower emissions · heat recovery · secondary combustion. 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.
