Thermal diffusion chamber with convection compressor

An apparatus comprising:

• a frame supporting a containment chamber;
• a sealed process chamber confined within the containment chamber;
• at least one fluid inlet vessel in fluidic communication with an exterior of the sealed process chamber, the fluid inlet vessel including at least a flow adjustment structure to control a fluid flow from a fluid source around the exterior of the sealed process chamber;
• an open loop fluid convection system in fluidic communication with an interior of the sealed process chamber, wherein the fluid convection system includes a rotary compressor assembly that extends into the sealed process chamber;
• a controller communicating with the flow adjustment structure;
• and
• a control signal buss communicating with at least the flow adjustment structure, and the controller, the control signal buss sends a control signal to the flow adjustment structure in response to a measured internal temperature value of an interior of said sealed process chamber, wherein the rotary compressor assembly includes a central shaft for rotation within the sealed process chamber.
