Air Cooling Induction Heating Machine
The LZF series cools the main power parts with air instead of a water circuit. That cuts the pump, the tower and the leak points when the job is low-temperature metal heating rather than a large melt. Catalogue models are 10, 20, 30, 40 and 60 kW on 380 V, 50/60 Hz, with 100 percent duty and a note that the machine can run continuously. The catalogue lists use on aluminum, zinc alloy and tin, on heat-conducting oil tubes, and on plastic-machine barrels such as injection, pelletizer and extruder heaters. It also lists induction melting of those low-melting metals.
What to check before you enquire
- No water on the main power components.
- 10–60 kW, 100 percent duty in the table.
- Low-melting metals and barrel heating.
- Continuous running is stated in the catalogue.
Typical applications
- Aluminum and zinc
- Barrel heating
- Oil-tube heating
- Low-temperature melts

Figures are taken from the LZ catalogue. Final power, frequency and capacity depend on the metal, coil, lining, duty cycle and your mains voltage. Ask for a technical proposal before you order. Figures in parentheses are US units (pounds, inches, feet, °F, psi).
