Introduction
Thermal Oil Boiler uses thermal oil as the heat transfer medium, heating the thermal oil to high temperatures 200°C–350°C. Thermal oil boilers operate at low pressure while reaching high temperatures, ensuring both safety and energy efficiency.
Work mode : manual, automatic
Structure: vertical, horizontal
Combustion: diesel lpg gas hfo, electricity, solid fuel wood biomass coal
How It Works ?
1. Heating – The boiler burns fuel (natural gas, diesel, coal, or biomass) to heat the thermal oil.
2. Heat Transfer – Hot thermal oil circulates through pipes to equipment, transferring heat to the process.
3. Return Cycle – Cooled oil returns to the boiler to be reheated, creating a closed-loop system.
This system allows precise temperature control up to 200–350°C without the risks associated with high-pressure steam.

Boiler Features
Compace coil tube structure
Horizontal chamber combustion three coil structure, its body is composed of outer coil, middle coil, inner coil and rear coil.
Wet back sturcture
Unique design for heating surface in end of boiler, somke chamber wet back sturcuture, make lower heat loss, improve thermal efficiency 2%-3%.
External oil tank
The design of the external oil collecting tank prevents the slow flow of grease carbonization and avoids accidents.
100% safety runing & best insulation
Double layer 12cm aluminum silicate insulation. Sealed tightly to avoid air leaks. Over oil temperature/over smoke temperature/low flow alarm.Technical Parameter
