Dissociated Ammonia Atmosphere Generator

Abbott Furnace’s Dissociated Ammonia Atmosphere Generators are designed to provide an economical source of pure, dry, highly reducing atmosphere. The dissociating process produces an atmosphere gas that consists of 25% nitrogen and 75% hydrogen. 

This gas can be used in many thermal processing applications where high hydrogen content is necessary in the furnace atmosphere. Dissociated Ammonia provides a dry hydrogen/nitrogen mixture that is produced by passing ammonia through a heated retort that contains a nickel catalyst.

Abbott’s line of Dissociated Ammonia Atmosphere Generators uses a vertical retort configuration with silicon carbide heating elements and are available in sizes ranging from 100 – 6000 cubic feet per hour. These generators are based on the historically robust Drever designs dating back to 1939. 

Abbott has added all of the improvements you would expect to see in new equipment today including state of the art controls with several PLC/HMI combinations, data logging, digital power controllers, and updated gas safety systems.

Nitrogen Bubbler By Abbott Furnace


The F.A.S.T. Moisture Control System (FMCS) is a hydration system designed to remove the high carbonaceous vapors emitted during lubricant removal from the preheat zone of a continuous belt furnace using steam injection, allowing the customer to regulate and maintain a constant Dew Point. The FMCS has also been shown to reduce stack emission particulate.

Abbott Furnace Methanol Control System


Abbott Furnace Company’s Methanol Control System, the MCS100, is designed to inject a constant stream of blended nitrogen/methanol into continuous belt furnaces. The nitrogen/methanol blend creates a process atmosphere that can contain up to 10% hydrogen by volume.
