PTP melting gas stationary furnace up to 1200 °C

A furnace that will save you money on operating costs

The PTP melting and holding furnaces are used for the alloys of a variety of metals (tin, zinc, lead, aluminium, silver, gold). Thanks to the gas burner used, this furnace has a high melting output. We have achieved minimal heat losses, and thus operating cost savings for you, by using top-quality insulation materials and a rotary lid. The alloy collar, meanwhile, ensures a long life for the crucible.

* Stated furnace width is inclusive of the burner inlet.
* Stated furnace height is inclusive of the closed lid.
** The melting output values specified in the table are maximum ones. They are achievable if the conditions mentioned below are complied with. Approximately 80% of the maximum value of melting output is achieved during real operation.
