Model GOX 50

We know and appreciate the simple medium Internet -


we will need a signed and sealed LOI with bank-information by fax before we send hardcopies, pictures, etc.



CONDITION OF THE EQUIPMENT: Used for 9 years (half-load)

600 L/day (510 cubic meters per 24 hours) or 25 L/hour of pure (99.8 %) liquid Oxygen (O2), is able to produce Hydrogen (H2) as well.



The air separation plant is constructed and designed for unattended operation. Only occasional inspections are necessary.

Operating changes with longer periods of time will be controlled manually, i. e. start-up, shutdown or deriming of the cold box. The plant consists of several units (packaged). These units, including all operation devices and all control devices, are designed for outdoor and are provided with noise- and weather protection. 1 air compression and purification unit ACP 1 oxygen and nitrogen generating box ONP Main advantages of this plant conception are workshop-mounted units, no bulding requirements, simple foundation work, short time and therfore low as well as civil work costs.

Constructional premises are a well-prepared site including approach roads, foundations for all units and compressors, utility supply and drainage.




INSTALLATION CREW: 3-4 technicians, available by seller

PRICE: 530,000 USD FOB Middle East

The price includes:

- Spare parts (95% of the complete set - new set costs $ 400,000)

- installation and launching

The similar plants now cost approx. 2,200,000 USD.

6. Complete set of spare parts

7. NOTE: Liquid storage tank for storage of cold liquid gases and filling liquid gas into other vessels of piping systems IS NOT INCLUDED and should be purchased separately - approx. market price 55,000 USD.


BASIC DATA FOR DESIGN AND ACCEPTANCE: Barometric pressure: 1,013 bar Air temperature: 35C Relative humidity: 0-100% Air condition: Normal industrial air, free of dust, oil, abnormal contents of hydrocarbons and other corrosive elements as well as other components as normally. Carbon dioxide content 300 ppm. Cooling water temperature: max. 10C Normal chemical composition of water for industrial purposes with a total hardness of under 18 dH (German degrees of hardness), free of algae and iron compounds. Cooling water pressure: min. 6 bar abs. Compressor delivery pressure: 14 bar bas. Electricity supply: 400 V, 3 phase, 50 HzFor actual operation of the plant under tropical conditions, the plant design shell allows a certain variation of the basic data as given above (i. e. concerning temperatures of cooling water and air temperature and humidity). Such deviations at the time of acceptance shall be taken into account using acknowledged technical rules. The design of the plant allows full flexibility between the production of gaseous oxygen and gaseous nitrogen.


Energy consumption:

(measured at motor shaft rsp. heaters at terminal with a tolerance of +/- % without liquid storage and product handling equipment)

Air compressor incl. Cooling fan: 118 kW Molecular sieve unit (average): 5 kW Others: 5 kW Total approx. 128 kW Cooling water requirement: Cooling water requirement approx. 4m3/h Regeneration gas: For regeneration of molecular sieves waste nitrogen will be used from the process unit. Deriming gas: For total deriming of the unit, air from the air compressor will be used.


Time required for deriming approx.: 12 hours

Time for cooling down process unit after total derimng approx.: 15 hours
