Methods and apparatus for processing a substrate are provided herein. For example, a cooling apparatus for use with a substrate support of a processing chamber comprises a heat exchanger, a manifold assembly comprising a first input configured to connect to an output of the heat exchanger, a second input configured to connect to a first coolant supply configured to supply a first coolant, a first output configured to connect to the substrate support of the processing chamber, and a second output configured to connect to an input of the heat exchanger, a gas input configured to connect to a second coolant supply that is configured to supply a second coolant that is different from the first coolant to the substrate support, a first three-way valve connected between the first output of the manifold assembly and the substrate support and connected between the gas input and the substrate support, and a controller configured to control supplying one of the first coolant or the second coolant during operation.
