Dilution Refrigerator Measurement Systems

Bluefors cryogen-free Dilution Refrigerator Measurement Systems are the global benchmark for ultra-low temperature cooling systems.

Contact Sales

Bluefors cryogen-free Dilution Refrigerator Measurement Systems are industry-leading, top-of-the-line cooling systems. They provide continuous cooling at ultra-low temperatures through the dilution process of helium-3–helium-4 mixture in a closed-loop environment.

The cooldown from room temperature is initiated at the push of a button, and systems can be operated and controlled fully remotely.

Product Highlights

Dilution Refrigerator Measurement Systems

Products

Fully Automated Operation

Fully automated cooldown sequence from room to base temperature, initiated with a single push of a button.

Superior Performance

Low base temperatures with superior cooling power, and fast cooldown times.

See specification comparison of the systems.

Reliable

Not a single soft solder joint in the dilution refrigerator cooling units, and a fully welded main heat exchanger.

Extensive Options and Integrated Products

Bluefors Systems have extensive additional options available to create an optimal system configuration based on experiment needs. Systems can also include measurement infrastructure and superconducting magnets, depending on your needs.

Temperature Controller

The Bluefors Temperature Controller enhances the user experience of our cryogenic systems. With a modern and intuitive user interface, you gain direct control and overview of the system’s temperature status.

The Bluefors Temperature Controller is fully integrated to all dilution refrigerator measurement systems.

Low Total Cost of Ownership

Oil-free pumps and compressors in the Gas Handling System guarantee minimal maintenance requirements, with a service interval up to 3 years. The systems contain only high-quality components such as Pfeiffer Vacuum pumps and pressure sensors, VAT vacuum valves and bellows.
