Pioneer Cryogenics can refurbish your old vessels to bring them up to current standards or even make them like new. From simple valve kit replacements, to complete pipework replacement, painting, and vacuum repairs, whatever your requirements are, we can meet them.

We also have extensive capabilities in making modifications such as adding additional pipes (either externally or internally), thermosiphon boots, access manways, internal recondensing systems for CO2, Nitrous Oxide, and Argon, reinforcement of legs and supports for increased wind and seismic loadings, major change of service (eg. Inert to Flammable), and any other modification or upgrade that you may require.
