Induction Heating Equipment - Stationary Tank Application


Further to your request to design an induction heating system for your 1,000 barrel stationary oil storage tank at the Andora Energy Sawn Lake site, we developed the following proposal to heat the heavy oil product to 50-80 C (120-180 F).

The proposed induction heating system will use three phase power with helical coils around the exterior circumference of the tank.  The three coils will be located near the bottom, where the primary heating will take place. Convection will heat the upper section of the tank.  This induction heating system design allows the tank to be nearly empty and still heated, similar to systems seen with steam heating coils. The power from your electrical supply is 600 volt, 400 (425?) ams.

This is an installed turn-key system.  We will provide the necessary personnel at your site to install and commission the system.   


POWER SUPPLY – 600 volts, 425 amp

The undiluted heavy oil product to be heated is represented by the assay provided, supplemented with a detailed assay prepared by Alberta Energy for Peace River in-situ oil.

For the system electrical requirement, 600 volt, 425 amp supply for the induction generator is capable of providing sufficient energy to heat the heavy oil product in a full  insulated tank from delivery temp (___ C) to desired temperature (___ C) in (____ hours) based on typical “winter” conditions. Extreme cold will extend the heating time by ___ %).   Warmer ambient conditions will reduce heating times.

The heating system unit is complete with a line disconnect switch, power components, solid-state controls, and all operator controls and safety devices.


Temperature sensors allow the power supply to operate as needed, minimizing electrical consumption when set temperatures are achieved.


The installation of the tank heating system includes the stripping of the existing insulation from the coil installation area, installing the coils, configuring and installing the power supply, and replacing the insulation.  

The plan for this tank coil installation includes:

  1. Remove 6’ of insulation and covering, revealing steel surface
  2. Install insulative underlayment prior to coil installation
  3. Install coils (three coils, each with 100 turns)
  4. Install insulative overlayment, on top of the coils
  5. Cover all back to match with secure watertight insulating covering (e.g. Polyurea).
