  1. HYDROGEN GENERATORS FOR METEOROLOGY AND INDUSTRY

  2. HYDROGEN GENERATORTYPE GIP™ 3 • Independent • Chemical process very easily used • Gas reserve possible • Especially adapted to isolated areas • Reliable

  3. DESCRIPTION Chemical hydrogen generator GIP™ 3 • Set of accessories: • 1 bucket13 litres • 1 Straight funnel • 1 bent funnel • 1 silicon basket3 m3 • 1 shovel • 1 poker • 1 brass brush • 1 spanner12” • 1 neoprene protective gloves • 1 protective goggle • 1 earthing device Closing assembly And draw off valve

  4. OPERATING PRINCIPLE • The process of hydrogen production with the GIP™ 3 generators is based on the attack of silicon by the caustic soda in aqueous solution under pressure and high temperature. • Its production per cartridge is 3 m3 of hydrogen (measured in conditions at 15 °C and 760 mm of mercury). • The caustic soda undergoes the action of pure silicon in autoclave. • Pressure is produced by the reaction itself, which is not reversible. • A local rise in temperature enables the liquid to reach a temperature high enough to compensate fully the retarding action of the pressure and to insure that the pure silicon is completely attacked. • The hydrogen is stored into the cylinder at high pressure.

  6. GIP™ REACTIVE CARTRIDGE • The GIP™ 3 type hydrogen generator cartridges are stored in waterproof metal boxes made of quantitative dosage of: • alkaline cartridge, • priming cartridge, • granulated silicon cartridge. • A manipulation allows the generation of 3 Nm3 of hydrogen volume within 30 minutes.

  8. MAINS ADVANTAGES • 3 m3 of hydrogen produced in less than 10 minutes • No electricity required • No specific quality of water required • Very few solid residues after the reaction • Low and easy maintenance • Life time of the cylinder up to 30 years • Equipment in accordance with the European regulations in force

  9. ELECTROLYZER TYPE BP-MP Independent Noiseless Automatic Safe Reliable

  10. H2 GENERATOR TYPE BPMP • The hydrogen and oxygen are produced at atmospheric pressure by one or several electrolysis cell serial connected • Each electrolysis cell is made of one anode electrode (oxygen production), one cathode electrode (hydrogen production) and one diaphragm (separation of oxygen and hydrogen). • The oxygen produced is directly evacuated into the atmosphere. • The hydrogen is stored at 5 millibars in the movable bell of the gasholder which is filled when gas is produced. • When the bell is full, the hydrogen is transferred from the gasholder to a storage tank by means of a hydrogen compressor. • The compressor automatically stops as soon as the gasholder bell is empty. • The compressor automatically re-starts when the gasholder bell is full and then stops; the same operating principle occurs until the complete filling of the storage tank. • The system will restart automatically after the filling of a second balloon in order to maintain full the hydrogen tank. • A water treatment system including a 20-liter demineralized water tank allows to make the periodical electrolyte level in the electrolysis cells.

  17. H2 GENERATOR TYPE MP8 • The hydrogen and oxygen are produced at atmospheric pressure directly under pressure by two electrolysis cells serial connected. • The electrolysis cell is made of one anode electrode (oxygen production), one cathode electrode (hydrogen production) and one diaphragm (separation of oxygen and hydrogen). • The hydrogen and oxygen produced are directly steered to a pressure balancer. • The pressure balancer has 4 level control probes, each of them having a role: • Safety by oxygen overpressure  sign of leak in the hydrogen circuit • Safety by hydrogen overpressure  sign of leak in the oxygen circuit • Oxygen / hydrogen pressure relief  necessary for the automatic recovery of the electrolyte levels inside the cells • Level control  cyclic extraction of the oxygen into the atmosphere • The hydrogen produced is directly transferred towards the storage tank through a weir and a sized hole allowing a flexible and homogenous filling. • The equipment automatically starts again after the filling of a second balloon so as to fill again the storage tank. • The periodical electrolyte level in the cells is automatically restored by adjunction of demineralized water.
