Local company popularises electrical heat tracing

Amid escalating costs of heating containers using traditional methods, such as steam or gas, a more cost-effective, efficient and controlled method of ensuring the constant heating of containers is electrical heat tracing (EHT), says eltherm South Africa MD Peter Stone. EHT specialist eltherm regularly supplies EHT systems for storage tanks and tank containers, or tanktainers, most notably tanktainers and road tankers. An electrical heating element runs the length of a pipe. The EHT system is then used to maintain temperature. EHT systems offer a broad range of temperature options as well. It can be designed for applications with low-freeze points, up to 1 000 °C process maintenance temperatures. In addition, EHT can be installed on short or long pipelines, making it ideal for large, concentrated solar power farms, as well as petrochemical plants.
