An RSH-Condensator has the capacity of eliminating up to 20'000 Heat instantly. It will not break or overheat, but it will stay in the Reactor with 1 use left. It can the be "repaired" with redstone dust for 10'000 each. (2 Redstone for full Repair)
THE LZH AND RSH CONDENSATORS SHOULD NEVER BE USED ALONE WITHOUT USING A REACTOR COOLANT INJECTOR. Not doing so will result in meltdown, even with a single cell.
