Testing under atmospheric pressure
With atmospheric test chambers it is not necessary to evacuate air before the test process.
Test chambers of this construction type can be manufactured at significantly lower cost with a significantly larger volume than vacuum chambers. We build these chambers with a chamber volume of up to 50 m³ as standard. This allows for reliable testing of even larger units and assemblies.
However, we also recommend atmospheric testing when delicate, vacuum-sensitive components such as devices with touch screens need to be tested for their leak tightness.
This system configuration also allows the filling of the test objects with SF6 gas in the test chamber and subsequent recovery of the gas. However, with atmospheric pressure, the test duration is on average 10 - 30 times longer as the increase in concentration for atmospheric pressure is significantly lower.call for prices

DILO couplings allow a connection to be made by simply screwing the two coupling parts together. Before the metal to metal seal closes the pressure and vacuum tight coupling is sealed inside by means of an O-ring. When loosening the coupling parts again, the same O-ring prevents gas loss whilst the self seal valves close.call for prices
Dilo-SF6Vacuum testing of smaller components (without gas handling) This model range with a chamber volume of approx. 50 - 500 l is the ideal solution for testing smaller components where gas handling can take place outside the test chamber.call for pricescall for prices
For reliable refilling of SF6 gas by overpressure
3-393-R001 Portable with rubber hose and coupling DN8 and DN20
3-393-R002 Portable in a case with rubber hose and couplings DN8 and DN20The handy devices allow filling of electrical equipment with SF6 gas directly from the bottle by overpressure. The primary gauge of the pressure reducer displays the bottle pressure in bar, the secondary gauge indicates the desired filling pressure to be set easily by means of the handle. The bottle pressure can be reduced to the desired filling pressure by the integrated pressure reducer. Other features:

- Self-closing couplings for emission-free gas handling
- Available as accessories for the world's most commonly used bottle connections
3-001-R021 Mobile as cylinder cart with wire braided hoses Refilling device as cylinder cart for comfortable on board carrying of a gas bottle. The primary gauge of the pressure reducer displays the bottle pressure in bar, psi and kPa. The secondary gauge indicates the desired filling pressure to be set easily by means of the handle. The bottle pressure can be reduced to the desired filling pressure by the integrated pressure reducer.
The weight of the gas to be refilled can be registered easily by means of integrated weighing scales. The weight is indicated on the illuminated display which switches off automatically if the scales are not used for a certain time. Thanks to the tare function high precision quantification of gas inputs and outputs is possible.call for prices

B195R01 With thermal transfer label printer
B195R02 Without thermal transfer label printer
This weighing unit is a useful tool for the SF6 gas bottle management in connection with the „SF6 Monitoring Manager“, a specially developed database software. The quantity of SF6 stored in gas bottles is precisely determined by means of electronic scales, incoming and outgoing gas vessels are identified by means of the integrated barcode scanner. The required bar code labels can be printed on site with the optional label printer (only B195R01).
Gas quantities being filled or withdrawn are registered by the weighing unit and are allocated to the corresponding storage location or customer location via the computer tablet. This unit also enables the registration of the gas quality (e. g. new gas or reuse gas). In filling mode any gas quantities can be withdrawn from the bottle and transferred to other gas vessels. Its difference is immediately registered in the database.call for prices
