Induction Heating For Vessels / Batch Reactors

Induction Heating for Vessels and Batch Reactors

Batch reactor vessel heating by electric mains frequency induction heating is the most advanced precision heating method available to any fluid processing company.

Due to the heating system being inherently simple and very reliable, the choice of heating by induction should be regarded as the preferred choice.

Melting Solutions Ltd has over 30 years experience in induction heating and has delivered vessel/batch reactor heaters to many countries all over the world.

Varying sizes with differing heat up rates can be offered as each vessel heater is bespoke to the customers needs.


• No physical contact between induction coil and heated vessel wall.
• Rapid start-up and shut-down. No thermal inertia.
• Low heat loss
• Precision product and vessel wall temperature control allows for minimal overshoot.
• High energy input. Ideal for automatic or micro-processor control
• Safe hazard area or standard industrial operation at line voltage.
• Pollution free uniform heating at high efficiency.
• Low running costs.
• Low or high temperature working.
• Simple and flexible to operate.
• Minimum maintenance required.
• Consistent product quality.
• Heater self-contained on vessel, allowing minimal floor space requirement.

Induction heating coil designs are available to suit metallic vessels and tanks of most forms and shapes in current use ranging from a few centremetres to several metres diameter or length. Mild steel, clad mild steel, solid stainless steel or non ferrous vessels can be successfully heated. Generally a minimum wall thickness of 6mm is recommended.

Unit rating designs range from 1KW to 1500KW. With induction there is no limit on power density input. Any limitation that exists is imposed by the maximum heat absorption capacity of the product, process or metallurgical characteristics of the vessel wall material.

Induction heating embodies all the conveniences of electricity taken direct to the process and transformed to heat exactly where it is required.  Since the heating takes place direct in the vessel wall which is in contact with the product, and the heat losses are extremely low, the system is highly efficient (up to 90%).

Induction heating offers many benefits unobtainable by other means.  It gives improved plant production efficiency and better operating conditions, since there is no significant emission of heat to the surroundings.

Typical industries using induction process heating:

• Reactors and kettles
• Adhesive and special coatings
• Chemical, gas and oil
• Food processing
• Metallurgical and metal finishing
• Equipment for which induction heating is ideally suited include:
• Batch Reactors and Kettles, Autoclaves, Process Vessels, Storage and Settling Tanks, Baths, Vats and Still Pots, Pressure Vessels, Vapourisers and Superheaters, Heat Exchangers, Rotary Drums, Dual Fuel Heated Vessels.

Melting Solutions Ltds’ engineers have many years of experience evolving custom built induction heating systems for a wide range of applications in a wide range of industries.  Heaters are designed to suit the exact requirements of the process and are constructed for quick fitting onto the vessel either in our works or on site.
