Thermal oil boilers

A thermal oil boiler heats thermal oil instead of water, delivering high process temperatures at low operating pressure.

Thermal oil boilers serve process heating in industrial plants that need high and stable operating temperatures. Thermal oil is the heat transfer medium, allowing efficient and reliable energy transfer without water or steam as the working fluid. They can be designed for solid fuel and biomass, liquid and gaseous fuel, or with electric heating.

Frequently asked questions

When should I choose a thermal oil boiler instead of steam?

When the process needs high, precisely controlled temperatures without high-pressure operation: thermal oil carries heat at high temperature and low pressure, with no evaporation or water treatment.

Which heat transfer fluid to choose: water or thermal oil?

The choice depends on the required operating temperature and the process requirements. Water is the right choice for heating systems and processes at lower temperatures. Thermal oil is chosen when the process needs higher, stable temperatures, precise control and heat transfer without the high pressures typical of water systems at a comparable temperature level. The final solution is defined by the required capacity, operating temperature, pressure and plant operating conditions.

Which fuels does a thermal oil boiler use?

Liquid and gaseous fuels (model TKT-TU), solid fuels and biomass, or electricity (model VAT-V-TU) where no flue gases or burners are wanted.

In which industries are thermal oil boilers used?

Chemical and petrochemical, food, textile, pharmaceutical and wood industries, asphalt plants and building materials, plastics and rubber.

What makes up a thermal oil system?

The boiler, circulation pumps, expansion and collecting vessel, safety and control fittings, automation with oil temperature and flow control, and an economiser where required.

How is a thermal oil boiler maintained?

By regular checks of thermal oil quality, cleaning of heating surfaces and inspection of fittings; TIPO Kotlogradnja offers preventive maintenance and overhaul of thermal oil systems.
