Melting and holding electric resistance stationary furnaces PT Mk.II

Furnace PT Mk.II

These furnaces are used as melting and holding furnaces for aluminum and its alloys. Maximum temperature in the furnace chamber is 1100°C (1050°C in crucible).

The PT Mk.II furnace is designed with focus on energy savings and is suitable even for foundries with limited installation space. The PT Mk.II’s high-tech insulating materials and new mounting system of heating coils allow for the smallest possible external furnace dimensions. The coils are placed in refractory castable shape grooves which prevent them from overheating. This placement also protects against splashing aluminum in the case of crucible breakage. The power consumption of the PT Mk.II is reduced to the minimum necessary. This low consumption, together with the furnace’s new insulation system, makes the PT Mk.II one of the most energy efficient devices for aluminum melting and holding on the market.
