PTPR melting gas stationary furnace with recuperation system up to 1200 °C

Recuperation to minimise your gas consumption

This furnace is used for melting metals at up toe 1200 °C (approx. 1100 °C in the crucible) and, if needed, subsequent pouring of the melting product over into a transport ladle or a transport holding furnace. In this it is then transported onwards for further processing. The furnace’s gas burner is equipped with a recuperator that preheats the air intended for use in combustion. Through this it reduces chimney losses and thus the furnace’s consumption. This in turn can give you gas savings of 25 to 30% compared to an ordinary gas furnace.

  • Easy to install, easy to control
  • Custom adjustments
  • 24-month warranty
  • Mechanical durability
  • High melting output
  • Long service life for crucible through the use of an alloy collar
  • Protection of the furnace against any damage to the crucible, in the form of a safety opening in the bottom of the furnace
  • Gas savings due to feeding the gas burner with preheated air from the recuperation system
  • The expected gas savings are 25 to 30% of the gas relative to ordinary gas furnaces
  • Minimal heat losses due to the use of top-quality insulation materials and a rotary lid
  • Quick crucible replacement thanks to the easy removal of the crucible lid
