The LZH-Condensator works like the RSH-Condensator but can cool up to 100'000 Heat.
It can also be repaired with Lapis Lazuli (Dye Only) for 40'000 (2.5 for full repair) or Redstone Dust for 5'000 (20 for full repair).
If you want to fully repair a LZH-Condensator you should use 2 Lapis Lazuli Dye and 4 Redstone Dust
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.
It is also repairable with an reactor coolant injector just fill the lapis-lazuli in the coolant injector and it will be automaticly refilled if you are using a "reactor containment field projector".
