A German ferrous foundry ordered twin coreless induction furnaces plus a shared IGBT frequency inverter package, “to gain independence and flexibility” and contribute to climate protection.

Otto Junker GmbH reports it has a contract to install a new coreless induction furnace operation for Hydrotec Technologies AG, Wildeshausen, Germany. The family-run foundry produces manhole covers, drainage channels, surface boxes, and other cast products for gardening and landscaping.

The purpose of setting up a new iron foundry now in Europe is “to gain independence and flexibility,” and to contribute to climate protection, promote the local economy, and create jobs.  The order is for delivery, installation, and commissioning of a new Otto Junker Duomelt JupiterLine coreless induction furnace plant, with two, five-ton coreless induction furnaces to be supplied with electrical energy by IGBT PowerCube technology for power distribution.

As outlined by Otto Junker, its dual furnace systems with a shared IGBT frequency inverter uses optimizes electrical power consumption by delivering melting energy to one vessel while keeping the metal warm in the alternate unit.

Its JupterLine furnaces have a capacity for 2 to 8 metric tons of iron.

For the Hydrotec installation, the new equipment will have a communication interface to a large photovoltaic (solar energy) system via a higher-level energy management system. The glycol-free air/water recooler will be equipped with a heat recovery system that will supply heat to part of an attached building in a sustainable and environmentally friendly manner to an attached building. Excess heat will be be supplied to a district heating network.

Otto Junker noted that the new installation’s Industrie 4.0 standard will be complemented by a patented OCP+ coil monitoring system, promoting sustainability, energy efficiency and climate neutrality standards.
