What is the difference between The Series 5, The Nano Star, The Red Giant?
A. The Nano Star is much smaller and can fit in more easily under bonnet spaces 2.0L Diesel, 3.0L Petrol and is designed to have the water resevior separately positioned to assist small space installation. The Red Giant has a much higher gas production output, so it will increase savings on the above sized engines and be more applicable where more gas is required on larger V8 and V6 engined vehicles, or vans that run at motorway speeds all day or use more heavy throttle due to payloads.
