A key issue we stress to our customers to consider when buying a security x-ray machine is the power supply availability. It is imperative that the power going to the machine is stable / regulated and that when the power trips or goes off that there is a back-up (ups) to shut the machine down properly. Many of our call-outs and spare part replacements are power related. The most expensive part is the generator tank, this is the nucleus of the machine and can cost upwards of R100 000 to replace. Other common failures that are normally power related is the computer systems. To replace this can cost around R50 000. The values shown here are approximation and you should inquire to get a more fixed cost of repairs.
