Electrically heated Ammonia Dissociator suitable for supplying up to 3000 CFH of atmosphere with a composition of 75% Hydrogen and 25% Nitrogen. This atmosphere is obtained by cracking anhydrous ammonia vapor in a catalyst filled vessel maintained at a temperature of 1700°F to 1850°F. Incoming ammonia pressure is reduced before retort entry. At the outlet of the retort the hot dissociated ammonia passes through a dry cooler where the gas is cooled to near room temperature. It then passes through a flowmeter and on to the consuming device. This dissociator includes a Sargeant &amp; Wilbur Ammonia vaporizer. This dissociator is provided with two (2)catalyst filled heat resisting alloy retorts. The retorts are mounted within the insulated dissociator heating chamber. The heating chamber consists of heavy Mullite T-Slot tiles. Retorts are heated with Sinuous-wound Nichrome Ribbon Heating elements which are mounted in the tile slots. The element tails and studs extend through the rear wall of the dissociator. Elements can be removed throught the rear wall without having to unpack furnace insulation etc. A step-down transformer (480V to 240V 112.5 KVA) is included. Manuals and drawings are also included. Very good condition.

1200 CFH Endothermic Generator

Description: Gas heated 2 retort generator. Refractory lined shell with vertically mounted retorts. Total of 5 Eclipse &quot;Thermjet&quot; spark ignited burners with UV scanner are mounted through the side of the refractory lined chamber for good uniform heating of the alloy retorts. The natural gas and air pass through a Waukee &quot;mixor&quot; valve then into the Waukee gas pump. Mixed gas enters the bottom of the retorts. The gas travels through the catalyst filled heated retorts and exits at the top. The exiting Endothermic gas passes through air cooled heat exchangers with cooling fans then through the Endothermic flow meters. Any excess exiting gas is burned off in flame rod monitored burn off
cans.
Controls: Honeywell UDC 3300 digital temperature controller. Honeywell UDC 2000 high limit and Honeywell UDC 5000 Dewpoint control along with all control switches and indicating lights are flush mounted in the control enclosure. Protection Controls 5 burner flame safety relay monitors all 5 burners. Two Honeywell flame safety relays monitor the 2 burn-off cans. Motor starters, fuses, timers, relays etc. are mounted inside the enclosure. Five (5) Waukee flow meters with pressure gauges are mounted to the front panel. 0-750 process gas, 0-100 addition gas, 0-2000 process air and (2) 0-2000 endothermic gas. Furnace Control Carbon probe.

This generator works well for commercial products that require a protective atmosphere. It produces a consistent endothermic gas and rarely needs to be adjusted. The owner is installing a generator with larger capacity so no longer needs this unit.
