1. An immersion cooling system for cooling servers, comprising:
an immersion enclosure having an immersion tank configured for immersing a plurality of servers in dielectric liquid;
a condenser arrangement situated remotely from the immersion enclosure, the condenser arrangement including a main condenser and an auxiliary condenser;
a vapor passageway configured for transporting vapor from the immersion tank to the main condenser of the condenser arrangement without transporting vapor from the immersion tank to the auxiliary condenser;
a containment passageway configured for transporting vapor from the immersion tank to the auxiliary condenser of the condenser arrangement independent of the vapor passageway; and
a resupply tank for receiving condensed liquid from the main condenser and the auxiliary condenser, the resupply tank having an inlet conduit for receiving condensed liquid from the main condenser and an outlet conduit for delivering the condensed liquid to the immersion tank.
