LENTON Debinding furnaces

Debinder furnace range

• Range of 3 sizes
• Heated zone of 600mm long over a single zone to accept a retort of 600mm internal diameter with a capacity of 6 cu.ft
• Heated zone of 1250mm long over three zones to accept a retort of 600mm internal diameter with a capacity of 12 cu.ft
• Heated zone of 1850mm long over a single zone to accept a retort of 600mm internal diameter with a capacity of 18 cu.ft
• Maximum temperature 1000°C
• Resistance wire spiral elements located in grooves on 2 sides of the chamber
• Cylindrical stainless steel retort to contain controlled gas atmosphere
• Honeywell DCP300 or Eurotherm 2408 programmer
• Multiple control and overtemperature type N MI thermocouple options

Debinder furnace with cooling

• Designed to remove binder under controlled atmosphere conditions
• Gas flow into the base of retort is controlled by two gas meters and the gas outlet is at the top of the retort
• A cylindrical retort is used to ensure a high temperature seal
• The retort body and diffuser plate are made of 310 stainless steel, with ends of 304 grade
• The atmosphere seal is made within the hot zone
• No surfaces are water cooled, therefore wax deposition will not occur
• Removal of the retort is made easy by a linear actuator which opens the hinged furnace top to gain access
• The access lid is equipped with an electric lift mechanism to assist cooling by being opened progressively from 600°C for faster cooling, and fully opened at around 
  300°C

Debinder furnace with forced cooling

• Additional gas sealed heat exchanger option available
• Independently trolley mounted, it will force cool the gas within a sealed retort, without reducing the atmosphere quality within the retort chamber
• Exhaust gas heat exchanger allows hot gas to pass through the central body of the heat exchanger, which is cooled by re-circulating water
• The re-circulated water is supplied by an air blown water cooled heat exchanger
• An exhaust sealed suction fan pulls gas from the retort through the gas exhanger, through the fan and then back into the retort

Debinder furnace with afterburner

• The whole system is designed to remove binder under controlled atmosphere conditions andthen burn off the waste gases
• The electrical burn off system is a high temperature metal tube through which all the gases pass
• The 800°C operating temperature, length and diameter of this device have been designed to ensure an adequate dwell time to ensure burn off all binders
• It is mounted above the main debinder furnace and wax trap from where uncondensed vapours are fed in
