What is the ASTM D4991?
Ensure safe transport of hazardous materials by air with ASTM D4991 - the standard test method for leakage testing of empty rigid containers.
What does DVACI mean?
DVACI comes from Spanish "Cámara De Vacío" which means "Vacuum Chamber" in English. The initial idea was to call the brand DEVACI, but the ".com" domain name was already taken, so we opted to drop the E and stick with a short 5-letter domain name "dvaci.com". We were lucky as 5 character domain names [...]
Can I add options after purchase?
No, this is not possible. All options must be ordered at the time of purchase.
Which safety regulations do your CDV comply with?
Our CDV Vacuum chambers comply with the European directives on which they are based, i.e. EN 61326-1:2013 electromagnetic compatibility EN 61010-1:2011 / A1:2020 electrical safety. These two directives lead to the CE marking of the device. These 2 directives have been verified by the Spanish laboratory: APPLUS located in Barcelona.
Do your CDV vacuum chambers meet USP 1207 CCIT standard?
Our CDVs equipped with Orion (PLC version) or Pharmaceutical CDVs comply with USP chapter〈1207.2〉 Container Leakage Testing Technologies - Probabilistic Leakage Testing Technologies: Bubble Emission and Liquid Tracer.
Why do my products inflate during the flight?
Due to the depressurization that occurs in the cabin / hold of the aircraft. In fact, airlines reduce the pressure by about -250mBar during air transportation. This is to minimize the cost of pressurizing the aircraft and to reduce mechanical stress on the aircraft. The same thing happens in the cabin where you travel. [...]
Why do my products that contain liquid have to be tested dry?
In order to be able to see the flow of liquid in the chamber it is best to test products containing liquid dry in our chambers. Products containing liquids often need to be tested "upside down" to ensure that any air remaining in the container does not escape first... The entire part of the [...]
Can rigid products (e.g. glass) be tested in DVACI chambers?
Yes, there is no problem to test the rigid containers, the stresses will be even higher in the sealing part. The difference in pressure between the inside and outside of the container will allow the test to be carried out with very good results.
What are the differences between the AUTO and PLC control versions?
In fact, these two versions are very similar and the differences are not obvious. The PLC version, which is the highest range, has a complete "ORION OS" operating system that allows you to install applications to control the products in different ways, such as on a smartphone. This version also includes a multi-user system [...]
What is the opening/closing mechanism of the CDV vacuum chambers?
All our units are supplied with a cover system guided by 2 hydraulic cylinders to facilitate opening and closing. These cylinders act as shock absorbers. This system prevents possible injuries that could result from handling a conventional bonnet without these "shock absorbers".
