Thermal Oil Heater

Introduction

At NORDSTONE, we specialize in the design, engineering, manufacturing, and supply of high-efficiency Thermal Oil Heaters (Hot Oil Boilers) for a wide range of industrial applications across Oil & Gas, Petrochemical, Chemical, Food Processing, Textile, Power, and Infrastructure sectors.

Our thermal fluid heating systems are engineered to deliver precise temperature control up to 350°C without the need for high-pressure steam systems, ensuring safe, efficient, and cost-effective heat transfer solutions.

What is a Thermal Oil Heater?

A Thermal Oil Heater (also known as a Hot Oil Heater / Thermic Fluid Heater) is a closed-loop heating system that uses heat transfer oil as the medium instead of water or steam.

Operates at high temperatures with low pressure
Eliminates scaling, corrosion, and steam losses
Ensures uniform heat distribution
Ideal for continuous industrial processes
