Vacuum Sealing Machines remove the air from a bag and sometimes replace it with inert Nitrogen gas then hermetically seal the package to give long-term oxygen free protection to the contents. Conservation By Design has been the leading supplier of Vacuum Sealing Machines and Barrier Products to the Conservation profession for many years. They are widely used for numerous applications as noted below. All of these machines are fitted with a unique exhaust that allows extraction of potentially dangerous mould spores when dealing with old or wet books and documents. PROTECTION High oxygen barrier enclosures like ArchiPress pouches give the conservator a new weapon in the struggle to resist the persistent decay caused by time, pests and disasters. The strong air and watertight pouches give additional protection against acidity, atmospheric pollution, floods, fire extinguishers, damp, mould, mildew, insects, vermin, careless handling and damage in transit. Anoxic enclosures are used for pest eradication, disaster recover and Squelch drying and to slow down oxidation and damage from UV light SPACE SAVING Compared to conventional envelope storage, vacuum storage has the advantage of saving between 40 to 50% of shelf space for the same volume of documents and could effectively double the capacity of an archive s shelving without the addition of a single extra shelf. SECURITY The special vacuum-sealed pouches protect their contents against unauthorised access to security documents. The opening of pouches cannot go unnoticed and requires the use of an ArchiPress machine to re-seal them. The pouches can also be printed with corporate logos and security or data retrieval information. In addition, coded seals can be supplied that fit in to the machines effectively branding information into the weld. Difference between vacuum impulse and chamber machines Vacuum Sealers Vacuum Chambers Medium Level of vacuum attainable (up to 70%) High level of vacuum attainable (approx 98.8%) Faster cycle time only the pouch is vacuumed Longer cycle time entire chamber is vacuumed Pouch size limited by seal bar length Pouch sized limited by chamber dimensions Horizontal and vertical sealing Horizontal or vertical sealing Double sided heating (bi-active) standard Double sided heating (bi-active) optional Uses Venturi or Busch (dry) pump Uses Busch (oil) pump

2 CXD Vacuum Chamber Machines A vacuum chamber removes the air out of a bag by use of a vacuum pump. On completion the bag is then sealed. Equipped with a clearly laid out and easy to program digital control panel, each machine features a 10-program memory. Additional filler plates are supplied in order that the working height inside the chamber can be adjusted for a variety of sizes of bag.

As a result the object is no longer under vacuum pressure. Oxygen levels can be further reduced by the inclusion of oxygen scavengers. Code Seal Text can be imprinted in the seal area that may be useful to impart a message or offer security. The advantage of text in the seal is that it remains intact until the bag is opened. Soft-air Soft-air is the ideal function to enable fragile items to be packed without damage. The air enters the vacuum chamber very gently after the sealing process giving the vacuum bag time to form around the fragile or sharp product. Sensor When it is important to obtain an exact vacuum or gas level we recommend a sensor. The standard machine normally relies on a time cycle for the vacuum and gas levels, which is accurate enough for most applications. However, when dealing with products that vary in volume or density, a built-in sensor ensures that each package is under the same level of vacuum to ensure consistency of pressure. Multi-cycles Occasionally it may be necessary to have a repeated sequence of vacuuming and gassing. The multi-cycles option makes this possible with up to 8 processes in one cycle. It is not possible to combine the multi-cycle with the sensor option.

3 CXD Vacuum Impulse Sealer The Vacuum Impulse sealer is a heavy-duty sealer for vacuum packaging and /or modified atmosphere (gas flush) packaging. The Vacuum Impulse sealer is easy to operate with nine different programmes built in as standard. Use the potentiometers to set the vacuum, gas, seal and cool time and press the foot pedal to start the vac/gas/sealing cycle. The pneumatic sealer requires a connection to a compressed air circuit with a pressure of 6 Bar (supplied). Both sealing bars are heated and can be positioned vertically and horizontally with four positions in between, to suit the working position. As standard the VI is supplied with a vacuum pump of 5m3/hr and a water discharge system. The machine is mounted on wheels for easy of maneuverability.

Press the foot pedal to close the sealing bars and the vacuum, gas flush and sealing cycle is automatically activated. After the last action has been carried out, the sealing bars open and the sealed bag can be removed.
