COOLPOWER i 系列冷冻机/冷头是基于热力循环运行以产生低温的制冷机。COOLPOWER i 冷头是 COOLVAC i 系列低温泵的关键部件。 

制冷机基于热力循环(卡诺)运行以产生低温 (T ≤ 120 K) 。

莱宝基于 Gifford/McMahon 原理运行的制冷机成功地应用于低温泵和低温应用。


根据工作条件和型号,冷头的第一级冷却至约 45 K 至 80 K,第二级的工作温度可降至 4 K。两级均由具有高热导率的铜制成,以充分利用制冷能力。



单级和双级 COOLPOWER i 系列冷头产品可满足多种应用需求。莱宝单级冷头 80 K 制冷功率 20 W 至 250 W ,双级冷头的二级20K制冷功率25 W 至 20 W 。

COOLPAK i 系列的氦气压缩机用于变频驱动 COOLPOWER i 系列的冷头,提高制冷能力。除了标准产品外,莱宝还可以根据客户要求提供定制冷头。


Easy maintenance

Owing to the simple design of the pneumatically driven built-in cold heads, maintenance is easy. It can be performed in place without detaching the cold head from the vacuum chamber. Maintenance for the mechanically driven cold heads is easy as well. It can take place at the place of use and can be carried out without impacting the surrounding infrastructure, in particular with no breaking of the chamber’s vacuum by the service personnel. Their eco mode is set for long term operation and lifetime energy saving.

High reliability and resistance

Our cold heads are used in applications which place particularly high demands on reliability, such as magnetic resonance imaging in medical technology, the cooling of low and high temperature superconductors, and the cooling of detectors in telescopes for astronomy. Their high refrigerating capacity as well as their high cooling performance with a sophisticated stepper motor concept make the COOLPOWER cold heads very reliable. Additionally they come with variable motor speed by adaption from the compressor unit, have a boost mode operation for increased cooling performance and fast and short cooldown times. Our Cold Heads have a lead-free regenerator and don't require liquid helium or liquid nitrogen. The COOLPOWER Cold Heads are RoHS compatible and have very low vibration levels.


Operation of the COOLPOWER cold heads is made simple by a simple key-press. The cold head can be operated in basically every orientation. They have easy process control and temperature control via an internet control unit.


With a small footprint and the option to operate the compressor and the cold head apart you will have near to no space problems.
