Difference between Model L and Model R Acetylene Compressors:

There are several similarities as well as differences when considering which model to purchase for the first time or replace when upgrading. Here is how your partner at Rexarc can support the various challenges.

1. 1. Changing from Model R to Model L requires full replacement: There will always be a need for Model R compressors. Some Rexarc customers prefer the Model R for various reasons and they will want to replace them with the same in the future. Because of this, Rexarc will give you credit for your old Model R Acetylene Compressor towards a new Model L. Rexarc will pay for the cost of returning the unit to Rexarc for re-manufacturing in preparation to re-sell to those who prefer the Model R and need to replace it but not at the price of a brand new unit.

1. 1. Spare parts not readily available: At Rexarc, we believe that there’s always a better way. We are working closely with our internal teams to identify kits for the Model L Acetylene compressor which can be shipped in rapid order direct to your location should you go down. If you have parts that you would like us to assemble and stock for you, please contact us with your interest.

1. 1. Customers may have to stock two sets of parts if going through a transition upgrade from a Model L to a Model R: This may indeed be the case during a transition. What Rexarc will do is buy back existing re-sellable Model R inventory at 50% of our selling price plus bear the cost of shipping back to Rexarc. Rexarc can also work with customers to identify what timing would be best to begin to transition based on their spare parts inventory.

1. Model L parts are generally more expensive: This is true. However, the total cost of ownership is lower because of the robust nature of the Model L design. We have seen several cases where there has been little to no damage when water has entered the compressor. The user simply removed the head of each stage, empty the water, replace the head and continue production. This has yet to occur in the Model R. Most often, should water enter the compressor, the crank, rods, and pistons are damaged which results in extended production down time and more costly repairs.
