Rotary Retort
/ Factory Built – All equipment is completely factory assembled, piped, wired and mechanically tested before shipment to minimize installation time and expense. Fast connection to utilities is assured.
/ Hopper/Loader – The hopper/loader is designed to charge a predetermined load of parts into the furnace on each revolution of the retort. Parts stored in the hopper are automatically transferred into the load bucket upon its arrival at the bottom position of the elevator. The loaded basket is then elevated and the parts are automatically deposited into the furnace.
/ Carbonitriding,
/ Hardening,
/ Carburizing.
/ Standard Equipment – Furnace lines are pre-engineered in standard sizes with rated capacities from 500 LB (225 KG) to 1,000 LB (450 KG). They can be manufactured, delivered and installed quickly. Custom engineered systems have been provided up to 4,000 LB (1,800 KG) per hour.
/ Electric Design – The electrically heated design features bayonet heating elements that can easily be replaced from outside of the furnace.
/ Gas Design – The gas fired design is equipped with centrifugally cast alloy radiant tubes and complete combustion system.
/ Retort – The cantilevered, one piece cast retort is supported at one end and sealed at the charge end of the furnace. There are no seals or bearings in hot areas or at the discharge end.
/ Rotary Mechanism – Auger flights convey the parts smoothly and quietly through the furnace. Rotation of the retort has a wide range of speed adjustments to provide complete fl exibility of time processing cycles.

/ Nuts,
/ Bolts,
/ Nails,
/ Washers and coins.
