Sold similar units to the power companies in GA called EMC. Units worked well (biggest complaint - the are too quiet for NASCAR country) - the Linde unit and I assume the unit you sold were set up for working in the rain as standard - sealed this & that's water gutters, etc.
Our EMC's are sort of like electrical power co-ops. They are in the business to promote "buying electricity" over natural gas so they need to practice what the preach - I weaved that thought into to my sales pitch (less direct than stated above of course).
Just make certain your service folks are trained on the units & have more than one set of service software to take care of the units. At the time these units were sold the service department was armed with one laptop load with software & one trained tech - a road tech. This caused some issues as you might imagine.
