Frequently Asked Questions

What is the maximum power consumption of this unit?
The UltraMelt 4/5 has a maximum absorbed power of 5kW.

Is this a static or centrifugal melting system?
The UltraMelt is a static induction melting system.

What are the cooling water requirements?
To operate safely, the system requires a minimum water flow of 2.0 L/min (0.5 GPM). The cooling water must have a minimum differential pressure of 3 Bar (45 PSI) and a maximum input pressure of 6 Bar (90 PSI).

Can I monitor the temperature without touching the metal?
Yes. While the unit comes standard with a thermocouple probe, an infrared (IR) sensor is available as an optional upgrade for non-contact temperature monitoring.

What materials can I melt with this furnace?
These furnaces are designed for both precious and non-precious metals and alloys. Specific configurations are available for gold (up to 5kg) and platinum (up to 600g).

Customer Reviews (4.0 / 5 · 5 reviews)

Claire S. ★★★★★

Finally got this set up for melting scrap gold, and the induction coil melts a 5kg charge in minutes with zero fuss. The digital display is incredibly intuitive, making it easy to hold precise temperature for consistent pours.

Avery ★★★★★

The digital temperature control is spot-on—I set it to 1,150°C and it held steady the whole pour. Melting 5kg of gold scrap took just under an hour, and the crucible handled the heat without any cracking so far.

Abigail I. ★★★★☆

I’ve been using this for small platinum batches and it heats evenly without overheating the crucible. The digital interface is straightforward once you get past the initial setup. Just wish the crucible was included.
