ABOUT OUR CAPSULES
All of our time capsules are made from 304 grade stainless steel. 304 is proven to be resistant to oxidation, corrosion and is extremely durable. Tungsten inert gas welding is the only welding process we use on our time capsules.
Prior to completion are capsules are hydrostically or pressure tested to ensure complete sealing.
Once you have filled your capsule, you might choose to have it argon-charged. The process of argon charging the packed capsule, removes the air and leaves a completely inert atmosphere in which mould cannot survive and oxidation within the capsule is not possible. If you are storing your capsule for more than 15 years we recommend Argon charging. The process can be completed by maintenance workers, engineering workshops or refrigeration specialists. Instructions are supplied with your capsule.
PACKING & SEALING
All capsules come complete with a neoprene seal, top bolts, dome nuts (304 grade), lubricant and simple instructions to seal your capsule once your contents are packed. If you are placing documents into your capsule we recommend printing on acid free paper. Which is readily available at stationary shops.
