Seven Factors to Determining the Right Vacuum Chamber
If you are shopping for a vacuum chamber, then the odds are that you have a specific application in mind. That is good, because a large number of your decisions have already been made for you. High quality vacuum systems are integral in many applications, ranging from industrial production to scientific experimentation. Even commercial kitchens frequently employ this technology. In order to make sure you get a vacuum chamber that meets your need. Here are the seven most important things to keep in mind while shopping around:
Vacuum chambers have a wide range of functions. In general, the material base of the chamber will be necessitated by the materials you need to put in it. This means that some of the biggest cost factors will be predetermined by the purpose of the chamber. Simulators and testers will hold wildly different items than food sealers. If you are using the chamber for manufacturing, then you need a chamber that can handle the molds, resins and production chemicals. The first step in shopping for vacuum chambers is determining exactly what you need it to do.
Once you identify the chambers that best suits your needs, you’ll need to consider pumps. Pumps and chambers are not universally interchangeable. One of the easiest ways to avoid compatibility issues is to look into vacuum chamber with pump packages. If that does not meet your needs for any reason, then you will need to research the pumps as well as your application requirements. Pump rate, micron pull, pressure ranges, durability and warranty are the biggest considerations when looking at pumps specifically.
You may have already determined how you need your vacuum chambers to be made, but you can typically choose from a range of sizes. Obviously you need a chamber that is large enough to perform your tests or handle your materials, but size affects more than just what goes in the chamber. Pairing with pump selection, the size of the chamber will significantly affect the time it takes to achieve the vacuum levels that you need. This will also impact the number of uses you can expect to get out of your pump. You need a chamber that is large enough for your work, but investing in too large of a system will cost you both time and money.
This will tie closely with function. If you need special seals, bags or tools, then you need to ensure there will not be chemical incompatibility. A full vacuum chamber kit can often supply you with all of the accessories for a specific test, but on a commercial level you will need a supplier that can keep up with your demand. From sous vide bags to molds, you need a chamber that can handle your extra tools and access to enough of them.
Most vacuum chambers are rated for either hours of operation or number of times a vacuum is created. As these devices are made with precision, they usually have costs that reflect the expertise put into their design and production. Making sure your chambers are backed by an acceptable warranty and service plan is usually in your best interest. Uncertified repairs will likely lead to expensive equipment failure, so enlist a provider who can take care of your tools when you need it.
This is determined mostly by function. Material production and manufacturing uses often require chambers that can handle high heat. Cryogenic vacuum chambers will expect the opposite. If you are performing tests or experiments, you may need to handle extreme hots and colds. Besides just choosing a chamber with a material that can deal with your thermal expectations, you can look into chambers that are treated for specific temperature ranges. You should also consider the conductivity of your chamber, as heating or cooling costs can be significant in some applications.
7. Pressure Capacity
This may be the very most important factor when shopping for vacuum chambers kit. What is the pressure rating? You absolutely need to know what pressure ranges your application requires before you select your vacuum system. This is true for the chamber, pump and accessories. If you need a single chamber to handle a wide range of settings, you can expect to pay more. If you need to perform mass production under specific conditions, you can save on cost by purchasing chambers that are less versatile. For the most part, this is a factor that is going to severely limit your options.
