Most Common FAQs
A thermic fluid heater, also known as a thermic oil heater, is an industrial heating system that uses thermal oil or heat transfer fluid to provide indirect heat to processes. It circulates hot oil in a closed-loop system, offering precise and consistent temperature control without high-pressure risks.
Thermic fluid heaters operate at high temperatures without pressurization, unlike steam boilers. They offer better energy efficiency, lower maintenance, no water treatment issues, and longer equipment life, making them ideal for continuous heating applications.
Industries like textile, chemical, pharmaceuticals, food processing, plywood, oil & gas, and packaging frequently use thermic fluid heaters for controlled heating and drying operations. They’re preferred where precise temperature control is essential.
High-quality thermic oil heaters can reach up to 300°C to 400°C, depending on the design and type of heat transfer fluid used. The exact range depends on your application’s process and fluid specifications.
You should consider factors like required heat load, temperature range, fuel type (solid, gas, oil, or electric), application type, and space availability. Consulting with an expert manufacturer like AS Engineers helps you select the right configuration.
