Fuel Savings

(Applicable to Diesel Vehicles Only) (Note: Fuel savings are dependent on various factors and cannot be rigidly fixed to any one specific number. For Petrol vehicles, no specific testing has been conducted yet, hence savings data or the amount of Hydrogen needed for savings is yet to be determined.)

• Highway Driven Vehicles: Up to 32%     ( test reports in a 27 tonne 7.2 L  2022 truck-  see webpage)
• City Driven Vehicles: Up to 32%       ( test reports in a 27 tonne 7.2 L  2022 truck-  see webpage)
• Off Highway: Up to 32%       ( test reports in a 27 tonne 7.2 L  2022 truck-  see webpage)
• Static: Up to 32%         ( test reports in a 27 tonne 7.2 L  2022 truck-  see webpage)

Emission Reduction

• CO2 Savings: Up to 57% reduction in net CO2 addition.  ( test reports in a 27 tonne 7.2 L  2022 truck-  see webpage)

Voltage Requirements for 24V Vehicles

• Gen 20 units have standard 12V fitment and cannot be used for 24V Vehicles. Use K40 if your vehicle has 24V power supply.
• 24 V vehicles can use a Redarc 24V/12V converter

System Servicing

• The first service is required after 3 months of use. Subsequent servicing is recommended every 6 months

System Life

• Although not fully tested, the expected lifespan of the system is projected to be more than 5 years.

System Physical Dimensions – Mounted into Welded Steel,  Aluminum enclosure box or Dewalt ToughBox 2 (53 cm x 35 cm x 35 cm)

• Width: 30 cm
• Length: 43 cm
• Height: 35 cm

System Weight

• Empty System: 16kg
• Fully Filled System: 22kg

Latest developments for these systems include the  use of new Resin filter system to increase the purity of the water electrolyte .  This development removes impurities from the water to produce Chemistry laboratory grade distilled to produce a purity of 52ppm from tap-water (800pm) or ground water 1500 ppm.

Removing impurities prevents any unwanted oxidation of the anode of an electrolysis unit , producing more gas for the electrical energy input and wasting much less energy as heat.

The Resin filter capsule is able to produce 50,000 litres of pure water and has a lifespan of 5000 hours.  The Capsule is easily replaced / serviced with a new filter module.  Contact Gavan on 0403177183 for more information of this produce.   Photos of the resin filter is seen on the “Shop” on this site.
