Inductive fluid heaters - advantages over resistance

Advantages in using the inductive heater for fluids over conventional electrical resistance

Precise control of the working temperature, low maintenance cost and the possibility of heating any type of fluid to any temperature and pressure are some of the advantages presented by the Inductive Fluid Heater, manufactured by BRASCOELMA.

This equipment, developed in 1983 by the company, stood out as the most efficient electric energy conversion equipment currently in existence.

Using the principle of magnetic induction, in the Inductive Fluid Heater the heat is generated in the walls of a spiral of stainless steel tubes. The fluid that circulates through these tubes removes that heat, which is used in the process.

These characteristics, combined with a specific design for each customer and the unique durability properties of stainless steel, make the Inductive Fluid Heater practically maintenance-free, requiring no replacement of any heating element during its useful life. . The Inductive Fluid Heater allowed the realization of heating projects that were not viable by other electrical means or not, and hundreds of them are already in use.

The Inductive Heater advantage cycle over electrical resistors can be defined below:

• Tubular shape of the heating element, increasing the heat exchange area.
• High convection heat exchange coefficient.
• Better efficiency in thermal exchange.
• Low temperature of the heating element (pipe wall).
• Elimination of the cracking (burning) problem of some fluids (fuel oils, vegetable oils, thermal fluids, etc.).
• Elimination of the need to replace heating elements.
• Savings in maintenance and electricity consumption (10 to 30% gain, depending on the process).
