Applications
|
| |
 |
Large Vessels and Bioreactors
The PHD-4
offers unmatched accuracy and repeatability, presenting a unique solution that
it is cost effective and very well suited for the leak range specifications of
this application. Biotech and pharmaceutical industries used to rely on pressure
decay and bubble test methods for finding leaks in their large bioreactors. The
PHD-4 has established a new standard of quality, significantly increasing
production yields.
* Fermenters
* Sterilizers
* Freeze
Dryers
|
|
| |
 |
Underground Pipes and Storage Tanks
The
portability and light weight of the PHD-4 plays a major role in this
application. Underground pipes and storage tanks (UST) are slightly pressurized
with helium which, due to its high mobility, can escape through small leaks and
migrate to the surface, where it can be easily detected by the PHD-4. The
accuracy, portability and light weight of this unit greatly simplifies this
process, particularly in difficult construction sites or rough terrain.
*
Gas distribution lines
* Under and above ground containers and storage
tanks
* Telecommunication and high voltage underground cables
|
|
| |
 |
Water Heating and Cooling Pipes
The PHD-4
allows leak location without interruption of the normal operation, by mixing
helium with the water in the circuit. Until recently, the precise and rapid
location of leaks in buried pipes has been very difficult.In the event of a
leak, helium desorbs from the fluid and diffuses to the surface, where it is
easily detected. Leaks in pipeline systems such as district heating systems,
drinking or chilled water systems and steam pipe networks incur high costs due
to losses and corrosion damage.
* Heater exchangers and steam
condensation lines
* Water pipes
* Radiant heating systems
* Brine
pipes
|
|
| |
 |
Airplane Fuel Tanks and Lines
PHD-4
technology is approved worldwide by airplane manufacturers and operators as the
standard for the location of leaks in aircraft fuel tanks and in oxygen
distribution lines. For this purpose, helium is injected from the outside into
the tank to be checked and the helium probe is used inside the wings to locate
any leaks.
* Fuel tanks
* Oxygen distribution lines
|
|
| |
 |
Other Applications
The PHD-4 is in daily
use in many other applications. Virtually any object requiring any level of leak
tightness can be simply tested with this instrument. Here is a partial list of
other applications:
*Components and systems for the Chemical and
Petrochemical Industries
* Components for the Automotive industry
*
Process gas delivery lines in Semiconductor fabrication industry
