20KW Electromagnetic Induction Heater with Water Cooled Induction Coil for Melting

Testing Model No. ZG-EH20 Cabinet type Electromagnetic Induction Heater

Input Power: 380V-3P

Main Control Cooling Mode: air cooled

Induction Coil (Melting Furnace Part): water cooled

Here we’ve used 20KW air cooled induction heater controller with water cooled induction coil. The induction coil must be cooled by water calculating flowing before the machine begin to work because the heating temperature can reach very high to 1100 degrees and rised very quickly. We tested the temperature rise to high around 2-3minutes. The induction coil can be made as a furnace with insulation mud and wool. We need to pay attention the melting pot, we also called crucible must be pure graphite one, if we use it for for melting gold, silver, copper, etc. And the melting speed can be very quick! But for melting we need to match a proper melting volume according to the melting speed you need. For example, 20kw for melting around 20KGs aluminium with a melting speed of 15-20mintues. It can also be used for melting other metals, but the melting point must lower than 1100C degrees.
