Case Study: 2.4M kcal/h Thermal Oil Heater Solution for an Asphalt Plant in Southeast Asia
For asphalt and bitumen production plants, temperature instability directly translates into product inconsistency, blocked pipelines, delayed loading, and costly downtime.
A leading overseas road construction materials producer recently faced these exact challenges in its bitumen production facility.
Their legacy heating system struggled with:
- unstable bitumen temperature
- excessive preheating time
- high fuel consumption
- pipeline solidification during cold nights
- inconsistent PMB blending quality
- rising maintenance frequency
To support highway and municipal road supply contracts, the client needed a stable, low-pressure, high-temperature heating solution that could run continuously.
After technical consultation, a customized YY(Q)W series Thermal oil heater Solution was selected and successfully commissioned. The result was a major improvement in temperature stability, plant uptime, and fuel efficiency.
Project Background: The Bitumen Heating Challenge
Asphalt quality is highly sensitive to temperature. The client required a constant heat source between 180°C and 280°C for mixing and storage. Their legacy equipment suffered from slow heat-up times and high fuel costs, leading to inconsistent product quality.
To remain competitive in 2026, the client needed a modern system that could meet strict environmental standards while lowering operational expenses.
The client operates a bitumen production and asphalt mixing facility serving large infrastructure projects, including:
- highway resurfacing
- municipal road maintenance
- airport runway paving
- bridge waterproofing
- PMB supply contracts
The process required stable heat between 180°C and 280°C across multiple production stages.
Pain Points Before Upgrade of the Thermal oil heater Solution
The original system created several critical problems:
1) Pipeline Blockage
Temperature drops during low-load hours caused bitumen to thicken in transfer lines.
This led to:
- emergency reheating
- pump overload
- production delays
- manual cleaning risk
2) Slow Start-Up Time
Morning restart required long preheating cycles before the plant could reach production temperature.
This reduced:
- daily output
- truck loading speed
- batch consistency
3) High Fuel Consumption
The previous open-loop heating arrangement wasted heat through:
- poor insulation
- unstable burner cycling
- long idle periods
- uneven tank coil heating
This pushed operating costs significantly higher.

Engineering Design Highlights of the Thermal oil heater Solution
1) Multi-Tank Heating Loop Design
The client had:
- 2 bitumen storage tanks
- 1 PMB blending tank
- 1 loading manifold line
A multi-branch thermal oil manifold was designed to ensure every point maintained stable viscosity.
This prevented localized overheating and reduced coke formation risk.
2) Fast Heat-Up Burner Matching
To reduce start-up delays, the burner was matched for:
- rapid outlet oil temperature rise
- stable PID modulation
- low-load night holding mode
- reduced overshoot
This shortened preheating time significantly. Similar asphalt case studies also show that improved insulation and flue-gas heat recovery around thermal-fluid systems can materially reduce gas use.
3) PLC Precision Temperature Control
The PLC system monitored:
- outlet oil temperature
- return oil ΔT
- tank asphalt temperature
- low-flow alarm
- burner fault history
- expansion tank level
- emergency shutdown
This was critical for PMB viscosity consistency and safer unattended night operation.
