PTE Mk.II holding electric stationary furnace up to 900 °C

Low operating costs and minimal structural dimensions

When we designed the PTE Mk.II melting and holding furnace for a variety of metal alloys, we emphasised energy savings, and it was also our goal to reduce these facilities’ dimensions. We have succeeded, so PTE Mk.II furnaces will find their application even in foundries with limited space for furnace installation. We have achieved the smallest possible dimensions thanks to our use of the latest insulation materials and a new system for mounting the heating spirals. We placed them in the grooves of refractory castable shaped blocks, preventing them from overheating and protecting them from molten aluminium if the crucible should happen to crack.

The PTE Mk.II furnaces belong among the most effective and energy-efficient facilities on the market for holding aluminium. And this is not only because we have reduced their power needs to a minimum, but also thanks to their new insulation system.
The PTE Mk.II even won an award in the “Golden Medal” contest at the MSV 2012 engineering trade fair in the “Best Innovative Exhibit – Energy Efficient Product” category.
