Are you holding molten metal in a cast house, foundry, or aluminum recycling? With TP® heater, be prepared to save energy and time while improving your metal quality and productivity. The aluminum immersion heater TP® heater is an electrical heating system, uniquely designed to hold and raise non-ferrous metals. It is intended to be directly immersed in liquid metal. The thermal power is directly brought to the heart of molten metal through conduction.

Thermal Power heater for aluminium immersion heating

Why you should use our aluminum immersion heating system?

We offer this technology to high-pressure die casting, low-pressure die casting, gravity die casting, cast house, and recycling industries. Our core and historical know-how are the immersion heaters. This technology has been developed to boost molten aluminum heating efficiency. Studies show that heating through an immersion heater is by far the most effective solution. Using our immersion heater can optimize your:

  • Energy saving
  • Metal quality
  • Productivity

Energy saving thanks to the immersion heating device

Because the immersion heater directly heats the heart of the bath, there is no heat loss. With a more efficient aluminum heating method, it enables you to save more energy. With our aluminum immersion heater‘s technology, you can reach your targeted temperature with lower time and energy compared to other technologies.

Technical characteristics

Our aluminum immersion heater is the combination of two advanced materials:

A silicon nitride sheath with the following technical qualities:

  • No sensitivity to thermal shocks
  • High mechanical resistance
  • Excellent thermal conductivity
  • Optimum resistance to corrosion

A high watt density electrical heating resistance embedded in a highly performing isolating material, providing both electrical isolation and heat transfer, standard dimensions:

  • Sheath diameter: 32, 55, or 75 mm
  • Length under flange from 500 to 1450 mm
  • Immersed length can reach 1000+ mm when allowed by the bath’s depth and work capacity
  • The connecting voltage from 36 to 600 V, mono/three-phase, delivering up to 50kW
