Leybold Germany offers two ranges of their portable helium leak detectors, The cost effective PHOENIX Industrial and the higher end Phoenix 4 range. Both come in three variants:

 

Dry = Dry backing pump for oil free operation

Standard = Oil Sealed roughing pump for faster pump down on larger volumes

Vario = Maximum flexibility as the backing pump is external to the leak detector and can be freely selected.

Phoenix 4 Range

Helium leak detectors PHOENIX - Where precision meets speed

Often the success of any business depends on quality, and having the right tools and equipment is critical to ensuring top performance and output across R&D departments, as well as in fast-paced production and manufacturing facilities.

We also see applications becoming more specialized, processes being more demanding, yet time for analysis and testing becoming less.

When it comes to vacuum system leak detection you can rely on our PHOENIX leak detectors.

The product portfolio of the PHOENIX 4 family provides the perfect device for a variety of applications.

• The PHOENIX Quadro Dry Plus – all the benefits of dry, with the performance of wet. Dry premium leak detector with Leybold's SCROLLVAC 3 Plus backing up ensuring improved sensitivity.

• The PHOENIX Quadro – as a universal, portable helium leak detector − is the all-rounder in its class. For applications with larger test volumes, which require faster pump down or repeated measuring cycles from atmosphere to test pressure.

• PHOENIX Vario is fully flexible and compact. It knows to convince with its unique free selection of the backing pump that is to be connected.

All versions are suited for the use in vacuum as well as sniffer operation.

The PHOENIX Quadro is available with oil-sealed backing pumps while the PHOENIX Quadro Dry Plus has a dry-running backing pump. Both come in a variety of different voltage versions.

The PHOENIX 4 series offers all the necessary connections for accessories including the sniffer line or the partial flow system.

Furthermore, it has easily accessible USB ports and additional controlling interfaces. We offer a range of interface modules with suitable communication standards for different needs: you can choose between an I/O module, Profibus®, Profinet®, Devicenet® or Ethernet/IP. 

The PHOENIX line has an improved service and maintenance concept. The filter can be changed from the outside, without removing the cover, letting you save time and focus on your measurements! 

PHOENIX Quadro Dry Plus

High-performance dry helium leak detector

The PHOENIX Quadro Dry Plus is the latest addition to the PHOENIX leak detectors range, delivering significantly improved performance thanks to the Leybold's SCROLLVAC 3 Plus backing pump.

Built to eliminate helium accumulation, the PHOENIX Quadro Dry Plus ensures no background interference and enables faster, more accurate measurements. The resulting quick high-sensitivity measurement is what makes the PHOENIX Quadro Dry Plus a game changer in dry helium leak detection. 

After helium contamination, it rapidly re-establishes highest sensitivity, matching the performance of traditional wet leak detectors, without the drawbacks of oil-based systems.

Designed for accurate and reliable performance, PHOENIX Quadro Dry Plus is the go-to solution for applications that demand peak cleanliness, precision, and minimal downtime without compromising on speed.

PHOENIX Vario

Small and flexible leak detector

​

​

​

​

​

​

​

​

​

The PHOENIX Vario has no built-in backing pump, and therefore has the smallest installation space of all PHOENIX 4 products with maximum flexibility. The type and size of the backing pump can be chosen freely depending on applications and process requirements.

The PHOENIX Vario thus combines the excellent properties of the PHOENIX 4 series with the required pumping system. In that way both oil-sealed and dry backing pumps can be selected and the fore-vacuum suction capacity can be adapted perfectly to the target application.

Advantages to the user

• Application-optimized pumping speed

• Extremely small installation space

• Very light weight

• Highly reliable measuring system

• Simple, intuitive handling

• Very high detection sensitivity

• Convenient remote control via smartphone or tablet PC without software installation

• Configuration and control using LEYASSIST

• Variety of interfaces for optimal device communication

• Innovative color touch display

• Extremely short response times

• Internal data memory as well as simple data output via USB

Recommended backing pumps for PHOENIX vario

The PHOENIX Vario can be operated with any backing pump, allowing full flexibility for the fore vacuum suction capacity. We strongly recommend using our latest SCROLLVAC plus platform. Please have a closer look at SCROLLVAC 3 plus.

Fore vacuum pumps that are electrically controllable, can be operated directly via the PHOENIX Vario. A prerequisite for this is a minimum final vacuum pressure of 2 mbar and a maximum current of 12 A. Fore vacuum pumps that are not electrically controllable, require a separate power supply.
