THE BENEFITS
Delta 3000 has been designed from the ground up with usability and reliability as cornerstones of the design. The result is a quality tester offering fast, flexible testing, translating to tangible benefits for the user.
- Increased Throughput
The Delta 3000 optimises the test time by maintaining the Actual Pressure to within +/- 1% (full scale) of Set pressure at every stage of the pressure curve and ensuring that the Set Point is reached before proceeding to the next step on the profile. - Decreased Downtime
The Delta 3000 has been engineered for reliability and consistency. Through ground up engineering design and the use of high quality components from the world's leading manufacturers SOMEX has set a new standard in reliability for beverage test equipment. - Simplicity of Operation
Process automation coupled with the clear and intuitive user-interface minimise setup times and operator training requirements. - Standard Compressed Air Connection
The Delta 3000's unique design removes the need for specialised high-pressure gas or air supply by utilising a standard 100-psi industrial compressed air connection. No more ordering, changing or storing high-pressure gas bottles. - Timesaving Accuracy
The Delta 3000's 1% full-scale accuracy throughout the pressure ramp ensures relative expansion results are true and eliminates any "false pass" results. - Compliance with test standards
Compliance of Delta 3000 with requirements of relevant test standards: The standards most commonly used for performing Glass and PET burst tests are:
Glass
ASTM Standard C147-86 (Internal Pressure Resistance (Hydrostatic): Glass)
PET
ISBT (International Society of Beverage Technologists) -
Voluntary Standard Test Methods for PET Bottles)
The Delta 3000 complies with all requirements of the standards

Description
The Delta 3000 is designed to pressure test Glass or PET bottles. Typically used in package testing laboratories, bottling plants or at a Glass bottle or PET bottle blowing facilities.
The Delta uses precise state of the art measuring and control systems to reflect accurately the actual pressure in the case of glass specimens or pressure and expansion in the case of PET specimens. Various ramp and dwell profiles can be created and stored in the machine memory.
The control system also holds a calibration routine for both pressure and volume.
This can be used for periodic machine calibration and is easily done by the user.
To change from testing a Glass bottle to a PET bottle requires only a program change; the tooling is universal across all bottle types. The Delta 3000 operates from a standard 100psi compressed air connection, it does not require connection to a high pressure gas bottle or air intensifier.
Technical Details
4 x Ramp/Dwell/Hold points.
Large memory for storing test profiles
PET
0 to 300 PSI (20 Bar) test range
Volume measurement with % expansion calculation for PET test
Holds up to 3 Liter bottles
Glass
0 to 1000PSI (68 Bar) test range
Holds up to 1 Liter bottles
Accuracy
A typical pressure profile consists of RAMP (psi/sec), PRESSURE SET POINT (psi), HOLD (sec.) - repeat.
Close monitoring by the control system ensures the actual pressure follows the set pressure profile to +/- 1% of full scale. Furthermore the controller will not progress to the next set point until the previous set point has been reached.
Note: it is important feature of pressure testing equipment to ensure the PRESSURE SET POINTS are being reached before beginning HOLD. If during a test the intended pressure was not being reached, before HOLD begins, a PET bottle is given more time to expand and as a result will burst at a lower pressure, additionally the PET bottle may be accepted as a "pass" without ever having reached the intended pressure.

Safety
Safety Circuit
There are several features to ensure access is denied to a specimen under pressure. The pressure chamber door is constructed from Polycarbonate of sufficient dimensions to withstand continual impact from bursting bottles
The pressure chamber is vented to ensure quick release of residual pressure from a failed bottle. The neck seal is interlocked, once engaged with a bottle to create a sealed circuit the chamber door cannot be opened.
The door is double interlocked to ensure the cycle cannot begin with the door in the open position. The double interlock also ensures the latch on the door is not released until the pressure head is in "home" position.
