• Frequency: 25-32 Mc/s
• Application: General-purpose heating, suitable for small-scale operations

The radio heater was designed with safety features for use by unskilled operators, fully enclosed, and simple to operate. It offered significant advantages in industrial processes:

1. Uniform heating: Ensured thorough heating of plastic preforms, resulting in consistent insulation quality regardless of thickness.
2. Efficiency: Typically, reduced production time by over 50%.
3. Versatility: Applications included plastic moulding, glue setting, hardening of small steel parts, and drying of low thermal conductivity materials.

Rediffusion also developed specialised electrode systems and heating chambers, improving the industrial appearance and functionality of their equipment. Notable applications included:

• Continuous drying conveyor for thick fabrics and paper board, using staggered transverse electrodes.
• Glue setting jigs for rescue dinghy paddles and desk assembly.
• The rapid concentration of heat-sensitive chemical liquids in a vacuum.
• Welding of PVC using an "electronic sewing machine".
• Curing of rubber samples.

The radio heater represented a significant advancement in industrial heating technology, offering precise control, efficiency, and versatility across various manufacturing processes.
