I would jump on this if it weren’t for my experience with vacuum controllers in general.
Vacuum controllers malfunction over time. To me a $5000 instrument meant to make my life easier needs to be purpose built to handle normal operation.
Even small amounts of solvent contamination, in my experience, can result in a malfunction. Can this controller handle significant amounts of solvent vapor without malfunctioning?
While the Concerto and SNAP controllers have been extensively tested and originally built for Cannabis distillation and solvent recovery applications, you are absolutely correct that a significant amount of solvent will result in malfunction. We do publish cleaning procedures for VPC, SNAP, and Concerto for this purpose. In our experience, cleaning these controllers returns them to optimal performance in most cases.
One thing to consider is controller malfunction due to cannabis oil is a good indication that there is product loss in the system. This might be an opportunity to revisit SOPs and make sure that Cannabis oil does not reach the controller, rather it reaches the collection container it was intended for.
Even if issues do occur, we offer services to clean and repair, in addition to warranty our products. If something isn’t working right, let us know. We are both the American designers and manufacturers of our products. We can fix anything DigiVac.
The guys on the floor have suggested that it occasionally will choose to go full vac instead of to your new programmed value for no apparent reason. I’m not certain if this is a fat finger issue or not, but the interface certainly isn’t perfect.
At the price I paid, I like it.
Definitely would be much less happy at full price. Not entirely unhappy. But certainly not excited.
