Low Frequency Heating Systems

IROSS™ Line Frequency Systems provide unique benefits over other types of induction heating units. Because the IROSS™ systems use low frequency induction (60hZ), they can be used to heat large and irregularly shaped workpieces for a variety of applications. These systems are generally used to achieve temperatures of 120 to 1600 Fahrenheit within a short amount of time, which makes it an attractive alternative to furnace/oven heating. Utilizing a low frequency allows for the heating of a large area as the depth of penetration depth is greater than that of a higher frequency induction system.

Some applications include:

  • Shrink fitting
  • Mold preheating
  • Stress relieving
  • Curing of rubber
