pro5 300ltr second hand is worth about £600-£800, depending on product water quality and age. if its 3 years or over it might not be crash test standard which will need extra welding done by Ionics plus fitting costs. if its got clamps and is crash tested standard it might be worth a little bit more.
Check the water meter on the system, it will give you an idea of how much the machine has been worked.
Look under the R.O there should be a date,this might give you a more acurate age of the system.
If it has diagonal bars on the sides of frame it should be crash tested.
I just bought another pro5 650, two poles 54ft and 40ft £1500. Might sell the poles if anyones intrested?
