hv uhv Unusual characteristics of vacuum are increasingly used in industry, research or technology. Vacuum due to the fact that there is a state of high gas thinning is an ideal environment for research. The use of vacuum is very broad and it is safe to say that many processes and technologies could not exist without it. Different processes use different ranges of underpressures, such as:
- low vacuum
- average vacuum
- high vacuum (HV)
- ultra high vacuum (UHV)
Thanks to many years of experience, our company specializes in supplying Vacuum Chambers (HV and UHV), Vacuum Components and Valves, and is engaged in providing services in the areas of: leak detection, vacuuming, customization of vacuum systems.


FRAKO-TERM supplies customized vacuum chambers in almost any shape, diferent materials and numbers of connections. Our biggest advantage is the ability to deliver large-sized chambers with a diameter of over 5 meters and a length of more than 15 meters. Each chamber performed by us is precisely measured and tested with helium leak detector. We do installations according to customer projects but we also have our own design office which can support the customer..


box valvesOur company has been supplying proven and safe components and vacuum fittings for years, including vacuum valves, vacuum couplings, vacuum flanges, vacuum rings, centering rings, vacuum clamps, vacuum adapters, vacuum pumps, etc. We also offer individual HV and UHV solutions. As a result, we help our customers create higher-end processes and lower operating costs by using high-quality materials.

Leak Detection

One of the most important feature of the vacuum system is the tightness of all components so that the system can work properly and achieve the required parameters for a given vacuum process. But not always, all elements are perfectly tight, so our company is concerned with determining the level and location of leakage of a particular system by helium detection.

To find leaks our company offers customer access or research in our laboratory, thanks to the experience and efficiency of our teams we are able to quickly determine the location and level of leaks.

Checking the tightness of the tested systems is based on the use of a helium detector that can be used in various ways. In the case of vacuum systems, the helium detector is connected directly to the test system in which the vacuum is produced. From the outside of the system - to all potentially leaking elements of the system - helium is sprayed. If at any point the helium enters the vacuum system it is signaled by a helium detector. This method allows you to determine the location of the leak and its intensity. In other cases, filling the test system or object with helium is used, and then "sniffing" outwardly the defective components with the help of a probe.
