About Hammer Gas Engineering
Hammer Gas Engineering GmbH, based in Dreieich, is a supplier of gas technology systems and gas analysers. The company develops, manufactures and maintains systems for the generation of protective and reaction gases, including endogas systems (ENDOGEN type), exogas and monogas generators (EXO 1-3, MONOGEN CHN 4), ammonia cracker systems (HYNIGEN), methanol reforming systems (METHYGEN) and nitrogen generators (INERTOR). The portfolio is complemented by gas purification systems (OX-EX 1-4, S-EX), gas drying systems (SEC 1/SEC 2) and analysers for water traces (EL-HY4) and thermal conductivity gases (CALVID), including analyser cabinets with sample gas conditioning. The range of services covers consulting, development, commissioning and service throughout the entire life cycle of the systems as well as retrofit solutions. The systems are delivered worldwide and serve, among other things, as carrier, inert and reaction gases for process atmospheres in heat treatment, metallurgy, chemistry and the glass industry. In 2025, the optimised endogas process ENDOGEN+GreenRetort was filed for patent.

Gases and Processes
Endogas generation (ENDOGEN / ENDOGEN+GreenRetort)
Generation of endogas from natural gas or propane as a reaction/carrier gas for heat treatment and chemical processes.
Exogas generation (EXO 1-3)
Generation of protective or reaction gas atmospheres from gaseous or liquid fuels.
Monogas generation (MONOGEN CHN 4)
Generation of monogas from natural gas, propane or propane/butane for metallurgical and chemical processes.
Ammonia cracking (HYNIGEN)
Production of hydrogen/nitrogen mixtures from ammonia, optionally with downstream purification and drying.
Methanol reforming (METHYGEN)
Generation of hydrogen/carbon monoxide mixtures from methanol.
Nitrogen generation (INERTOR)
Generation of nitrogen from air, optionally with downstream purification to increase gas quality.
Gas purification (OX-EX 1-4)
Catalytic and adsorptive purification of argon, nitrogen, hydrogen and gas mixtures, also as recovery systems with loss-free regeneration.
Sulphur removal (S-EX / S-EX Duplex)
Adsorptive removal of sulphur and sulphur compounds from fuel gases such as natural gas.
Gas drying (SEC 1 / SEC 2)
Drying of industrial gases by refrigeration drying or adsorption drying with different dew points, also as recovery systems.
Water trace measuring device (EL-HY4)
Trace analysis of water contents in industrial gases for monitoring plant equipment.
Thermal conductivity gas analyser (CALVID)
Qualitative monitoring and control of plant processes by means of thermal conductivity measurement.
