Hositrad Vacuum Technology

represent ColdEdge Technologies providing custom <4K to 1000K closed cycle cryostats with interfaces.

They provide GM & Pulse Tube technologies from SHI Cryogenics of America, Displex®, CTI Cryodyne, and other popular closed cycle coolers.


ColdEdge Technologies supply also open cycle flow cryostats that use liquid helium or LN2 as the cooling source

Without the pressure of having to sell our their cryocooler brand, Coldedge can work with the researcher to arrive at the best cryocooler solution for the researchers particular requirements and interface needs.

They supply complete systems with application specific and/or custom vacuum enclosures, radiation shields, sample holders, windows, temperature sensors, heaters, extra experimental wire leads and feedthroughs (UHV, SMA, coax & other), temperature controllers, vacuum pump systems, sample manipulation attachments, low vibration CCR interfaces and many other additional options. Interfaces with sample in vapor, sample in vacuum, UHV and custom interfaces are available.

Interface customization is their speciality - send us your sketch and we will work it into your design.       
ULV Benefits Nanometer displacement Ultra Low vibration Closed Cycle Cryocooler
The levels of vibration are inferred by feedback we get from our customers. For example, while using our ULV there is no line broadening during Mossbauer experiments, the system is used on SEM's and with <4K bolometer's so in order for these performance parameters to actually happen in these applications the vibration levels need to be below 10 to 15 nanometer's. This is how we have backed into our specifications.
