The suit repairs unit is a block that is used to repair suit. It can be crafted, but it also can be found at the Observatory.
How it works
To use the Suit Repairs Unit, you will need a power source, the Generator for example. It will take a moment till it powers up, then you must right-click it. It will show you the player with the armor, the durability of the armor, the cost and your balance. If your suit is repaired already, it won't work, otherwise you can click the repair button and you suit will be undamaged again.
