Applications
Select an application to see how our process heaters address your specific transport infrastructure heating needs.
Asphalt mix quality is set in the drum dryer. Moisture left in the aggregate causes foaming at the pugmill and premature stripping on the road surface. Temperature overshoot oxidises the binder and produces brittle pavement that cracks within two winters. Our indirect process heaters deliver 750–2,500 kW of precise, modulating thermal output to rotary drum dryers and parallel-flow mixing drums — holding aggregate discharge temperature within ±3°C of target across variable feed moisture and gradation.

Key advantages of indirect process heaters for asphalt production and bitumen handling operations.

No Direct Flame on Binder
Indirect heat exchange keeps combustion gases and open flame away from bitumen — eliminating coking, oxidation, and fire risk at the tank or drum.
Precise Aggregate Temperature
Modulating burners hold drum dryer discharge within ±3°C of target — preventing moisture retention, binder stripping, and brittle mix from overheated aggregate.
750 kW to 2500 kW Output
Single and double-burner EcoHeat configurations scale from small batch plants to continuous high-throughput drum mixing operations producing 300+ t/h.
Multi-Fuel Flexibility
Natural gas, LPG, or biogas — switch fuel source to match site infrastructure. No burner modifications required, reducing operational costs and carbon footprint.
20+ Year Service Life
Free-floating tube bundle absorbs continuous thermal cycling without stress cracking — engineered for the harsh, dusty, 24/7 environment of asphalt production.
Rapid Startup & Load Response
Cold to full output in ~30 minutes. Modulating controls respond in seconds to feed moisture and gradation changes — no production gaps between loads.

Ripped-Up Road.
Aggregate discharged too cold traps moisture — the mix foams at the pugmill and strips on the road within one winter. Too hot, and the binder oxidises into a brittle film that cracks under traffic loading. At the tank, a 10°C overshoot cokes bitumen onto the heating surface and degrades the polymer modifier. EcoHeat indirect heaters hold every temperature set-point within specification — from drum discharge to tank storage — with zero direct flame on the product.
Modulating heat output ensures aggregate reaches target discharge temperature every time — driving off residual moisture before it reaches the pugmill.
Indirect heating eliminates local hot spots on tank shells and coils — maintaining binder viscosity and polymer properties without coking or fume generation.
Fast-responding modulating controls compensate for feed moisture and gradation changes in seconds — delivering consistent mix temperature to the truck, load after load.
