    This must be a "Big box store" unit. Stores like Costco, Target, Walmart etc. I have worked on these units many times. In the 30 years of refrigeration, I had the experience of working on small self contained units, single compressor units, multiple compressor racks, ( I worked in a new Shop Rite supermarket that had a medium temp rack with 9 compressors and about 34 circuits. ) These days they usually use loop systems. Loop systems are just a main liquid line, main suction line, and some places a main hot gas line that goes around the store and the case circuits draw off of the loops. Have worked on CO2 racks, chillers, ( 134a, 22, ammonia, ) Of course water towers, with or without inverters, Regular condensers with or without inverters, self contained cases with R290, ( propane) Air conditioning units, window, split or ductless, roof top units from 1 horse power to units you walk into to service them, Fan units that are big enough to suck you into the blower wheel, water pumps, one I had the pleasure of working on, drew 985 amps while running, heat exchangers, both steam and cooling, motors from 1/20 hp to around 200 hp, compressors that were hermetic, semi hermetic, screw, scroll, Ice machines, cube, crushed, nugget, pneumatic controls, plc controls, and I am sure there is more. That is the good point of working for a company that services office buildings and supermarkets. Supermarkets have just about everything. They give you a great range of experience. The "on call " sucks, as some Ding – a – Ling will call in a case that has one nine watt motor out at 2 am and wants you to come out in the snow, on a 12 degree night to fix the freaking thing when it can wait to the normal starting time when the whole crew is in. This is one of, if not the best trade. I made a ton of money working in this trade, started my own business which is doing very well. You do have to be a person who is willing to hustle and work long hours for sure.
