Thermal Fluid Heaters

Introduction

Babcock Wanson Thermal Fluid Heaters with integrated gas, oil or dual fuel burner meet the needs of modern industry. With thermal fluid as the heat transfer medium, users are not confronted with the well-known problems of pressure, scale formation, corrosion or frost.

The extensive range of Babcock Wanson references in Thermal Fluid Heating emphasises the quality of our equipment and our ability to find the optimum solution for each application.

Thermal Fluid Heating systems have revolutionised process heating, making large, energy hungry and heavily manned plant rooms a thing of the past for the majority of industries. Thermal fluid heating systems are compact, easy to use and offer a saving in overall energy demand that is hard to beat.

Unlike a steam system, there is no change of state of the fluid with Thermal Fluid Heaters, so no condensate and therefore no flash steam losses, no blow down losses or make up water demand, there is no effluent discharge and the systems are completely corrosion free without the need for expensive chemical treatment. It all adds up to substantial savings for the operator.

Operating Principle

Thermal Fluid Heating is based on a similar principle to a simple hot water system. It consists of a heater connected to carbon steel flow and return pipework which can provide heat to one or more users or systems. Instead of water running through that pipework, a thermal fluid – typically specialist mineral oils or synthetic based fluids are suitable – is used as the heat transfer medium. Different fluids can be used to meet specific process heating requirements, making it a very flexible system.

What are Thermal Fluid Heaters Best Suited to?

Thermal fluid heaters typically operate at up to 350°C at atmospheric pressure and remain pumpable down to minus 20°C and lower with special fluids, which makes it a solution suitable for a multitude of applications.

Advantages of Thermal Fluid Heaters

  • Easy Operation
  • No freezing hazard
  • No liquid effluent produced
  • No water treatment or chemicals required
  • Very low maintenance and very long plant life
  • Corrosion free
  • Closed circuit operation – no loss system
  • High combustion and plant efficiency
  • 20% to 50% less energy consumed to transfer the same amount of heat compared with steam
  • Lower total exhaust emissions
  • Very safe
  • Compact and requires no specialist site work, so can be sited close to the user, meaning substantial savings in specialist plant rooms and distribution pipe work
  • Ability to maintain constant temperature control
  • Ability to work at high temperatures (up to 350°C in standard form) in a simple closed loop
  • Cost effective
