Claim:
1. A cooling system comprising: a first cooling module, the first cooling module including a first condenser receiving refrigerant from an evaporator, the first cooling module having a first pumping unit including a first variable speed pump and a second variable speed pump, the first pumping unit circulating refrigerant through the evaporator, the first cooling module defining a circuit having fluid flowing from the evaporator toward the first condenser then toward the first variable speed pump; and a second cooling module, the second cooling module including a second condenser receiving the refrigerant from the evaporator, the second cooling module having a second pumping unit including a first variable speed pump and a second variable speed pump, the second pumping unit circulating refrigerant through the evaporator, the second cooling module defining a circuit having fluid flowing from the evaporator toward the second condenser then toward the second variable speed pump, wherein the first and second pumping units are configured to operate at less than full capacity, and when one of the first cooling module or the second cooling module cannot sufficiently circulate refrigerant through the evaporator, the output of the pumping unit of the other of the first or second cooling modules is increased to compensate for the one cooling module.
