Trace heating for storage tanks

The primary purpose of a storage tank trace heating system, is to avoid and compensate for heat loss certain liquids undergo during a production process.

Of utmost importance is that the fluid or product held in the tanks does not freeze, change viscosity, or harm the storage tank itself.

Of utmost importance is that the fluid or product held in the tanks does not freeze, change viscosity, or harm the storage tank itself.

Installation

To install the heating cable to the body of the storage tank, several methods may be used, the two most common options are:

• Tethered to guides.
  Two or more parallel guides are installed transversally on the side of the storage tank body, to hold the cable.
• Tethered to a mesh.
  A polyethylene mesh is affixed to the side of the storage tank body, to which the cable is held.

Installation example

Installation example of trace heating for storage tanks:

• Installing the tethering guides for the heating cable.
• Placing the heating cable circuit.
• Connection to the control and regulation box.

Heating cable

For storage tank heat tracing projects, we recommend constant power parallel heating cable, model CTCS.

The parallel heating cable has a constant lineal wattage even when it is cut to required length.

Its principal feature is the heating wire which is wound in a spiral around the parallel conductor, insulated from the conducting wire except at contact points set at one metre intervals, alternating between each of the active conductors. In this way, the heating cable forms a series of elements running in parallel all fed by the same power cable which acts as the body.

To choose the best solution for your project:

• See the Parallel heating cable of our website.
• Contact the Heating Cables catalogue.
• Contact our technical department

Materials estimate

To correctly design a heat tracing system for storage tank, it is important to know all the physical and electrical specifications of the system that requires tracing, which is why it is preferable to have all the plans and system flow diagrams.

Ask for a materials estimate for tracing for storage tanks using any of these options:

• Post, fax or email the plans of the tank and the product to be stored.
• Or contact our technical department.
