The heating of tanks is a common industrial practice in many applications. Heating may be required to maintain pumping viscosity of heavy oil or resins, to prevent crystalline precipitation (sodium hydroxide), to facilitate production processes, for freeze protection, and hundreds of other applications. MATRUSREE offers literally hundreds of ways of heating tanks of all sizes. Included in this guide is an overview of the types of tank heating approaches. The manual is not meant to be a complete guide to each of these heating methods, rather an overview of what is available. Once a specific method is selected, further investigation should be made into the suitability of the heater for the application. Finally, the manual is a detailed guide on sizing heaters for large tanks. This guide includes sizing details that are beyond the scope of the sizing guide presented in the general catalog.
  • Medium tanks 1500 Liters to 3000 Liters.
  • Large tanks of 3000 Liters to 30 thousand Liters.
  • Very large tanks 30 thousand Liters and over.
There are many approaches to heating tanks of these sizes. The many solutions that MATRUSREE offers are reviewed in the next section. In addition to storage tanks, many other tanks are employed in manufacturing processes, such as:
  • Finishing tanks
  • Wash and rinse tanks
  • Cooking vessels
Open top tanks used in these applications typically employ over-the-side heating assemblies as well as screw plug or flanged immersion assemblies. This manual may be used for sizing small open top tanks. Please note, however, that this manual includes much more detail than is typically required for sizing small process tanks. It is recommended that you consult the P120 or the P2000 for some additional examples. Finally, a computer based calculation tool is available that is designed specifically for rectangular open or closed top tanks used in the finishing industry.
