PTSPR melting gas tilting furnace with recuperation system up to 1200 °C

An efficient furnace for easy pouring of melting products

This tilting gas furnace with recuperation can help you to save 25-30% of gas when compared with standard gas furnaces. We have furnished our gas burner with a recuperator, which preheats the air intended for use in combustion. Through this it reduces chimney losses and thus reduces the furnace’s consumption. 

This furnace is used for melting metals at up to 1,200 °C (in a furnace chamber; approximately 1,100 °C in the furnace’s crucible) with the option to transfer the melting product into a transport ladle or a transport holding furnace.

A melting gas tilting furnace with a PTSPR recuperation system save 25–30 % of gas when compared with standard gas furnaces

We have furnished our gas burner with a recuperator, which preheats air intended for use at combustion. Using this method, chimney losses are reduced which results also in furnace’s power consumption reduction. Furnace has minimal heat losses due to the use of topquality insulation materials and a rotary lid - a compact octagonal configuration of the furnace designed to reduce the dimensions of the unit and heated furnace chamber.


As an example, we present the PTSPR 1000/09 furnace consumption measurement when melting 1,000 kg of aluminium when compared with a standard available melting gas furnace:
