LCCM Conversion- NOT

The photo above shows a modification done to a cryogenic liquid cylinder to convert from an LCCM pressure building/ economizer regulator to a more common style regulator.

This is not a manufacturer's approved modification and is a case where the possible risks likely outweigh any gain. Some of these risks include:

- the refusal of some or all repair centers (except the modifiying vendor's) to work on liquid cylinders that have been substantively altered from their original design. The potential liability resulting from the failure of a modified vessel is just not worth the minimal profit that might be made from rehab work.

- the possibility that knowledgeable end users might also consider these conversions to be unacceptable.

- the fact that liquid cylinders that are modified in this manner can never be returned to their original LCCM operation.

LCCM regulators are indeed expensive to replace, but most can be rebuilt. And- trying to convert to a less expensive regulator by substantially modifying an original manufacturer's design of a DOT vessel can have the appearance of a dime getting in the way of a dollar........
