Applications
Select an application to see how our process heaters address your specific metal industry heating needs.
Non-ferrous smelting — aluminium, zinc, copper, and lead — demands sustained, precise heat without direct flame impingement on the charge. Our indirect process heaters deliver 750–2,500 kW of controlled thermal output for pre-heat chambers and holding furnaces, reducing oxidation loss, minimising dross formation, and improving melt yield per tonne. No direct combustion contact with the melt, no thermal shock from uneven heating.

Key advantages of indirect process heaters for smelter, coating, and surface treatment operations.
No Direct Flame on Metal
Indirect heat exchange keeps combustion gases and direct flame away from your charge, melt, or coated part — eliminating oxidation loss, fish-eye defects, and solvent flash risk.
ATEX-Compatible Operation
Fully enclosed combustion with no open flame contact with solvent vapours — designed for use in or near ATEX Zone 1 and Zone 2 classified degreasing environments.
750 kW to 2500 kW Output
Single and double-burner configurations scale from small batch pre-heat chambers to continuous high-throughput powder coat lines and large industrial degreasing tanks.
±1–3°C Process Stability
Modulating burners maintain set-point across variable load — critical for consistent degreasing bath chemistry, uniform powder cure, and controlled melt temperature in holding furnaces.
20+ Year Service Life
Free-floating tube bundle accommodates thermal cycling in high-temperature metal applications without stress cracking — engineered for continuous 24/7 industrial operation.
Multi-Fuel Flexibility
Natural gas, LPG, or biogas. No burner modifications required to switch — match fuel supply to site infrastructure or energy contract changes.
Built to Fit
Your Operation
Drop-in heat source for your existing smelter pre-heat chamber, cure oven, or degreasing tank — standard connections, minimal downtime.
The Wrong Heat Source
Costs More Than Fuel.
Direct flame on a melt charge raises oxidation loss and dross formation. Combustion gas in a cure oven triggers fish-eye rework. Open-flame equipment on a degreasing line fails ATEX compliance. EcoHeat indirect heaters are engineered to remove heat as a process risk — sealed combustion, modulating control, and zero product contact with combustion gases, by design.
Indirect heat keeps combustion gases out of the pre-heat chamber, reducing the oxidising atmosphere around the charge — improving melt yield by 0.5–2% per tonne.
Zero combustion gas contact with oven recirculation air eliminates silicone contamination, delamination, and gloss deviation — no rework, no wasted coating.
Fully enclosed indirect combustion eliminates any open-flame contact with solvent vapour zones — meeting ATEX Zone 1/2 requirements for safe bath heating.
