New Range of Package Leak Testing Vacuum Chambers
Chambers within our ACBXX-PT-SS range were designed for package testing within the food and medical industries. For instance, each package leak testing chamber comes with a submerge plate, vacuum regulator and drainage valve. Additionally, these chambers are often situated in moist environments hence they are fitted with a corrosion resistant vacuum manifold, which is comprised of a vacuum isolation valve, air admittance valve and an AVE vacuum display gauge. The set up makes them perfect for water submersion bubble leak testing which determines leaks in flexible packaging.
To evacuate our ACBXX-PT-V systems, a 28.0” Hg Venturi Pump is used. These pumps take advantage of the venturi effect—as a stream of compressed air exits a constricted orifice the resulting pressure drop draws air through a vacuum port. Moreover, since they require no oil or electricity, the resulting vacuum (up to 29.5″ Hg) is clean and efficient. They are intrinsically safe due to possessing no moving parts or electrical hazards.
Our ACB chambers are compliant with ASTM D3078-02 and ISO 20484 testing standards and are tested to a vacuum of 5×10-2mbar, and helium leak tested.

At AVE, we take pride in our diverse range of acrylic chambers and custom design service.
Among our recent projects, this pair of cylindrical chambers has been delivered for research within the aerospace industry.
These chambers were supplied with a complete manifold comprising of a vacuum isolation valve, an air admittance valve, and an AVE vacuum display gauge. The client also requested additional ports to accommodate the introduction of various gasses and sensory equipment.
To ensure the vessel was maintained at a safe pressure during gas introduction, a pressure relief valve was incorporated. During experimental procedures the chambers are strapped to a centrifugal plate. Grooves machined into the chambers ensure this is a secure and user friendly mounting mechanism.
After months of collaboration with our custom design service, the client was exceptionally happy with the product. In testimony to this, an additional eight units are in production and are set to further expand research capabilities.
All of our acrylic chambers are compliant with ASTM D3078-02 and ISO 20484 testing standards, they are tested to a vacuum of 5×10-2mbar, and helium leak tested. This makes them ideal for a wide range of experimental purposes.

This custom mild steel vacuum chamber was purposefully designed for testing packaging at altitude during aerial transportation. The advanced vacuum controller allows the 800mm3 internal volume to be evacuated gradually over a specified period. It can then be maintained at the desired vacuum level before smoothly returning to atmospheric pressure.
Positioned on the right-hand side of the door, the control panel allows the operator complete freedom to set up personal recipes and adjust the evacuation characteristics within the chamber.
The chambers design includes an aluminium door mounted via heavy-duty hinges to the powder coated mild steel framework. To ensure structural integrity our design team conducted Finite Element Analysis and applied appropriate, yet non-invasive bracing. Every member of the AVE team had a part to play in the successful development and delivery of this project. As it leaves the shop floor, we take pride in our latest achievement.

This 64 litre package testing chamber is to be used in a clean environment so the customer wanted an oil free solution, hence the Venturi vacuum generator and then all of the fittings across the chamber were upgraded to stainless steel for a food safe contaminant free solution as well.
The Venturi is capable of producing a vacuum of around 50mbar so the regulator on this system is set to maintain a pressure of around 300mbar. More than adequate for package testing with the bubble leak detection method.

This fully customised Bell Jar Vacuum System has had a heat plate installed along with a separate control panel to monitor, as well as control the temperature of the plate inside.
For safety reasons the system was fitted with a vacuum switch so that the heater wouldn’t turn on until it was under vacuum. The bell jar was also fitted with some temperature sensitive stickers to indicate what temperature the glass is.

This nice little system is using two of our motorised stirrers in two DP27 and DP76 vacuum chambers to degas various oil mixtures in the smaller tank and remove air from the pellets in the larger tank before using pressure differential to pull the liquid into the larger tank and fully infuse the pellets with oil.
This rule in physics allows many applications to take advantage of pressure differential and apply it to their processes, this is just one single example but is used all the time wherever there is fluid flow.
This vacuum system is a very smart piece of tech. even if we say so ourselves.
With a vacuum chamber capable of 2 x 10-8 mbar and a smart PLC system fully automating the process this customer can now ditch their old Edwards 306 Autocoaters and process their filaments in record time. The old coaters were taking around 40 mins per cycle of 1 -2 filament trays, but thanks to the Agilent scroll pump and Leybold TurboVac our system can complete a cycle of up to 4 filament trays in just 10 minutes with a single press of a button! (well a finger tap on the integrated touchscreen anyway)
The chamber is fully electropolished stainless steel with a sliding shelf for easy loading, again with fully electropolished tray and stainless steel sliders.

Sometimes things don’t quite go to plan or plans change, but that is the best thing about engineering, you find a way to make things work and learn from mistakes.
Originally this acrylic vacuum chamber was supposed to be working not much below atmospheric pressure and had gloves in to allow the user the ability to manipulate their product inside. However after a lot of changes and different pressure requirements (and a lot of broken gloves) it was decided the only way to achieve the desired manipulation inside the chamber was equalize the pressure inside and backfill with an inert gas, however they needed a specific value for absolute pressure so it wasn’t really an option. Instead we filled the holes in and they manufactured a clever little system of actuators to manipulate their cartridge under vacuum.
The final chamber is a bit of a Frankenstein box, but that’s okay, we live and learn and it does exactly what is needed of it, plus the 240V electrical power, 2 x USB and ethernet feedthroughs all work perfectly adding really nice functionality to this vacuum chamber.
This HUGE tank was sent on its way recently to be used in degassing large transformers. The vacuum chamber was so large we decided to have some metal pallets made up and mounted it on top for ease of manoeuvrability around the customers facility, plus they look rather striking.
This vacuum chamber has a lid made from polished aluminium rather than our usual acrylic lids, due to its sheer size and has lifting eyes to help lift on and off the chamber during use.
Below is the 42Ltr version of our new AVE-STIR-20 variable speed controlled motorised vacuum stirrer. We have these available as an add on for our DP42, DP76 and DP118 vacuum degassing chambers.
