Electrical Heat Treatment
At LD Heat Services UK LTD, we provide expert electrical resistance heating solutions designed to meet the specific demands of industrial applications across the UK. This process uses electrical current to generate heat directly within metal components, delivering precise temperature control without the hazards of open flames. The result is a clean, efficient, and reliable method that improves the quality and longevity of your materials.
How Electrical Resistance Heating Works
Electrical resistance heating involves passing an electric current through a conductive material or specially designed heating elements. As electricity encounters resistance, heat is generated internally and transferred evenly throughout the component. This targeted heating method allows us to avoid overheating, reduce thermal stress, and achieve consistent temperature control, making it ideal for applications where precision is critical.
Resistance heating utilises direct contact and heat radiation to raise metal temperatures up to 1200°C. Our flexible ceramic heating elements are compatible with all types of metal, ensuring versatility across projects. The compact and mobile nature of our equipment allows easy relocation around site, offering excellent operational flexibility.
Equipment and Capabilities
Our standard machines deliver power outputs of 50 kVA, suitable for most applications, with 70 kVA and 100kVA units available for larger or more demanding jobs. Each unit can control up to six thermocouples, allowing precise monitoring and regulation of temperature during both pre-heating and post-weld heat treatment processes.
Inverters
We also utilise practical handheld inverter units designed for fast-service applications and locations with limited access. Weighing just 17 kg, these lightweight devices are ideal for smaller, cost-effective jobs, capable of performing both pre-heating and post-weld heat treatment (PWHT) with ease and precision.
