DIS specialises in wiring & building PPU flight cases at our workshop. Over the years we have built many PPU systems and are familiar with installing as much equipment in to each system as possible. We understand the more flight cases in a system the more it costs for shipping. We have the experience of getting as much equipment as possible in to the rack and cabling the system very neat/tidy and maintainable. DIS welcomes any of their customers to do off-site testing and commissioning at our workshop.
