    APC, Stulz, Data Aire... All are inferior to Liebert in my opinion.
    Also, in-row cooling designs are the way to go.
    LIEBERT IS THE CADILLAC OF CRITICAL ROOM COOLING!

    410a systems are even more prone to clogging LL driers.

    May have got away with it using 22, but never with 410 & POE oil. We fix a lot of these after poor install. Purge with nitro during all pipe work. Triple evac & use ACCURATE micron gauge.
    ONLY 2 things are meant to be in a working refrigeration system.....refrigerant & oil!
