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 PLC + HMI package automates process control & data acquisition.
