Applications for the Series C include after cooling, dehumidifying and heating rotary-lobe and multistage centrifugal blowers used in air separation and printing systems. The modular heat exchanger has removable cores via the front and back sides of the pressure housing without disassembly of the gas line. Pressure tests from a full vacuum to 50 PSIG are available. Heat exchanger housings can be built to contain several cores with separate or shared access panels. Mist eliminators also can be built into a housing to prevent condensed moisture from carrying downstream.
