Thermic Fluid Oil Heater

A Hot Thermic Fluid Heater (thermal oil heater) is an industrial heating system that circulates a specialized heat-transfer fluid at high temperatures under low operating pressures. Unlike steam boilers that require high pressure to reach high temperatures, thermic fluid heaters can operate up to 300°C to 350°C at near-atmospheric pressure, drastically reducing explosive risks and structural costs.

Efficient, Uniform Thermal Energy

A Hot Thermic Fluid Heater (also known as a thermal oil heater) is an industrial heating system that circulates a specialized heat-transfer fluid at high temperatures under low operating pressures. Unlike steam boilers that require high pressure to reach high temperatures, thermic fluid heaters can operate up to 300°C to 350°C at near-atmospheric pressure, drastically reducing explosive risks and structural costs.

The Atlas Thermic Fluid Oil Heater utilizes advanced combustion technology and a multi-pass heat exchanger design, delivering exceptional thermal efficiency of 88% to 92% (with air pre-heaters or economizers). The fully automatic PLC control system monitors and adjusts temperature, fuel flow, and combustion parameters for optimal performance.

settings Key Components & Design Features

  • check_circle
    Double Jacket Concentric Coil: The heater core consists of precisely wound multi-start helical coils. The thermic fluid flows through these coils, absorbing radiant and convective heat from the burner flame.
  • check_circle
    Circulating Pump: A high-temperature, centrifugal pump (often with a water-cooled or air-cooled mechanical seal) that maintains a turbulent flow inside the coils to prevent the oil from overheating and cracking.
  • check_circle
    Expansion & Deaerator Tank: An overhead tank that accommodates the thermal expansion of the oil (which expands by ~7% per 100°C rise) and vents out trapped gasses or moisture.
  • check_circle
    De-Asphalting / Strainer System: Inline high-mesh filters that trap carbon sludge or degraded fluid particles, preventing scale buildup inside the heater tubes.

flowchart System Layout and Flow Mechanics

The thermal fluid follows a closed-loop cycle. The basic loop configuration is:

Heater → Process Equipment (Tanks / Mills) → Return → Pump → Heater

The fluid is heated in the heater, circulated through the process equipment (tanks, mills, or other heat exchangers), and returned to the heater for reheating in a continuous closed-loop cycle.
