Mar 19, 2018 · Endothermic Gas Generator Added to Brazilian Fastener Heat Treatment System March 19, 2018 Featured News, Manufacturing Heat Treat, Manufacturing Heat Treat News A major fastener manufacturer in South America recently received delivery of an endothermic gas generator intended for heat treatment operations at the company's Brazilian plant.
The necessary gases are either injected directly into the furnace as a nitrogen and methanol (CH4) mixture or via an endothermic generator using propane or natural gas as the source for carbon. An endothermic atmosphere is produced by cracking methane into nitrogen, hydrogen, and carbon monoxide in a retort.
Lindberg HYEN Endothermic Generator Lindberg/MPH's HYEN generators provide protective atmosphere that is considerably less expensive than a nitrogen based atmosphere dur to the availability of natural gas or propane and the efficiency of Moldatherm insulation used in the generators.
Atmosphere Heat Treatment. Operating conditions: in an atmosphere of air, inert gases (nitrogen, argon, hydrogen), active atmospheres for carburizing, nitriding and other active diffusion atmospheres, in high temperature systems up to 1300°C, low vacuum in retort furnaces up to 10-2 mbar. Application: our solutions are used in a variety
Industrial Box Furnaces. Lindberg/MPH has long been a leader in the design and manufacture of thermal processing box furnaces. These heat treat furnaces save you money when treating large volumes of material per hour with exceptional uniformity and low maintenance. Industrial Box Furnace Specifications. Temperature Range: up to 2500°F.
AN OVERVIEW OF ENDOTHERMIC GENERATORS . Technical Data . The endothermic generator creates an atmosphere to provide a positive pressure in a heat treating furnace, and a platform on which a carburizing or decarburizing environment can be formulated, by addition of enriching gas or dilution air.

Endo Gas (endothermic gas) Generators Produce Endothermic Gas (mixer or CO, CO2, N2 and H2) by reaction of air and fuel nickel Catalysts at 1050°C temperature. Endothermic Gas Generators Principle: Endothermic Process requires external heat which is provided by electrical Heater of fuel burning
Endothermic Generator Operation Endothermic atmosphere is prepared by reacting a mixture of hydrocarbon gas, typically methane or propane and air, metered in a proportion such that there is just enough oxygen to form carbon monoxide and hydrogen without excess carbon dioxide or water vapor.
wise, an inert gas (vacuum) is selected. Endothermic Gas Atmospheres Endothermic gas generators are common equipment in the heat-treat shop. The main components of an endothermic gen-erator (Fig. 1) consist of: † Heated reaction retort with catalyst † Air-gas proportioning control compo-nents † Pump to pass the air-gas mixture through the retort
Endothermic gas (CO/H₂/N₂) is often used as a 'neutral' protective gas or carrier gas during heat treatment process. Monitoring and controlling the furnace gas composition is essential to ensure metallic products retain their desired properties.
See the Gas Summary Chart for specific gases and applications. General Applications: Endothermic Generator produces protective atmosphere for: Hardening of carbon and tool steels. Annealing and normalizing of carbon steels. Carburizing. Carbonitriding. Sintering.
Endothermic atmospheres used for heat treating. These gases are produced using either endothermic generators with natural gas or propane as the carbon source, or injection directly in the furnace using nitrogen and methanol mixtures. In this article, we are going to discuss the formation of endothermic atmospheres for the protection of parts during austenitization.

The Endothermic Gas Generator creates an atmosphere to provide a positive pressure in a heat treating furnace and a platform to formulate the carburising environment. Endothermic Gas Generators from HIGHTEMP feature a unique soot-free control system with an excellent reputation for trouble-free operation.
Endothermic gas compositions are one of the most popular atmospheres used for heat treatments and are often used as a 'neutral' hardening gas, or carrier gas for carbonitriding or carburizing. The production of endothermic gas mixtures is often produced by endogas generators that increase the temperature of natural gas and air with a catalyst present.
Endogas atmosphere generators produce an endothermic gas for many protective surface heat treating processes. The generators heat fuel gas and air under controlled conditions to provide either a rich or lean endother- mic gas containing hydrogen, carbon monoxide, and nitrogen.
Nitrogen Generator for Blanketing (Covering) Gas: A term used to describe an inert gas such as nitrogen or argon introduced into a furnace to prevent oxidation of the component parts being heat-treated. The flowrate and pressure of the atmosphere and the equipment type (i.e. gas-tight construction) must be sufficient to limit the influx of air.
The type of hydrogen used in heat treatment furnaces is referred to as dry hydrogen and is 98 – 99.9% pure. Endothermic Atmospheres The protective gases used in furnace atmospheres are usually a mixture of hydrogen, nitrogen, carbon dioxide (CO2), carbon monoxide (CO), and trace amounts of water.
