Model & Technical Parameters
Standard models below. Capacity, power and frequency are matched to your alloy, output and grid at the quotation stage — non-standard ratings are built to order.
| Model | Capacity | Rated power | Frequency | Melting rate (Cu) |
|---|---|---|---|---|
| GWT-0.1 | 100 kg | 100 kW | 2,500 Hz | 0.20 t / h |
| GWT-0.25 | 250 kg | 160 kW | 1,000 Hz | 0.35 t / h |
| GWT-0.5 | 500 kg | 250 kW | 1,000 Hz | 0.60 t / h |
| GWT-1 | 1 t | 400 kW | 500 Hz | 1.00 t / h |
| GWT-3 | 3 t | 1,000 kW | 500 Hz | 2.40 t / h |
| GWT-5 | 5 t | 1,500 kW | 250 Hz | 3.60 t / h |
Technical values require confirmation against the final equipment configuration. Rates given for electrolytic copper cathode. Brass and bronze melt faster but require zinc-vapour extraction.
Product Details
Copper melting is a conductivity problem: copper couples well, so power density has to be controlled to avoid overheating the bath surface while the charge below is still solid. The GWT series uses a frequency and power profile matched to copper's resistivity, giving fast melt-down without localised superheat.
Brass and bronze release zinc vapour at melting temperature. We supply a hooded extraction canopy and, on request, a bag filter unit, so the workshop stays within occupational exposure limits and the zinc oxide is recovered rather than vented.
Typical duty is continuous casting of copper rod and billet, brass valve and fitting foundries, and bronze bushing production.
