Cool For Progress
The horizontal model LH is a low-height, compact and truly horizontal dilution refrigerator measurement system capable of operation under different tilt angles. It is ideal for beamline, telescope or detector experiments.
All line-of-sight ports reach from room temperature to mixing chamber.
The Bluefors Temperature Controller enhance 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.
Fully automated fast warm-up option, which allows overnight warm-up for our standard LD systems.
Service Packages and Extended Warranty are available upon request
Note: Cooling power is measured on experimental flange outside MXC.

Above is a cool-down curve for a configuration of LH horizontal dilution refrigerator measurement system measured with a calibrated resistance thermometer.
Pulse pre-cooling sequence (see spots 2 and 3) is one of the key points in reducing the cool-down time. Because we do not use exchange gas some parts of the dilution refrigerator unit stay ‘hot’ on cool down, which prevents condensation of the mixture. By repeatedly admitting the mixture from the tanks through the low impedance still side of the dilution refrigerator and then pumping it out again, these hot spots are effectively cooled down.
The basic requirements are 3-phase electricity, cooling water, compressed air. The full list of requirements and specification details can be found in the Pre-Installation Guide, please contact our sales team for a copy.
