Batch Type Pit Retort Furnace

Pit retort furnaces are designed for use at moderate pressure upto 600 mm WC and are heated by wire coils placed outside an alloy retort. Steam is superheated and recirculated. A heat exchanged condenses exhaust oil vapour & steam and a burn off is provided for oil mist and hydrogen. The system design ensures a high degree of temperature uniformity and the availability to load oily parts without pre-cleaning. 

  • Fluidtherm Pit type steam treatment furnaces are equipped with a retort and a (sealed) lid that houses a powerful circulation fan

  • Designed to work at higher than normal pressure (typ. upto 600mm ( 24²) WG.) the furnace is equipped with an off gas condenser which periodically discharges condensed steam & oil and burns off hydrogen and oil vapour

  • This facility enables the charging of oily parts without pre-cleaning.

  • The high degree of temperature uniformity caused by intensive recirculation of steam (preheated within a coil) and thyristorised heating control ensures a high degree of quality consistency.


A combined steam treatment and nitriding process to obtain a uniform nitrided depth on porous parts.
