We present the design and performance of a compact, fully cryogen-free cooling platform as a technology demonstrator for quantum hardware applications. The system leverages a four-stage continuous adiabatic demagnetization refrigerator (cADR) to achieve continuous cooling below 30 mK without the use of helium-3. Integrated mechanical and superconducting heat switches enable efficient thermal cycling, while high-density radio frequency (RF) wiring provides the infrastructure required for control and readout of a five-qubit superconducting quantum processor. Housed in a single rack with a spacious, accessible sample stage, the platform demonstrates that cADR technology can be realized in a compact form factor and provides a basis for future quantum hardware platforms operating under stringent space and infrastructure constraints.
