Curious, Here in the USA most markets use Hussmann, Tyler and Hill for market equipment. Everything from racks to singles from evap towers to air cooled condensers. compressors are Copeland and caryle. We use E-2s,Comtrol Rdm and Danfoss for controlers. Refrigerant is 404a, 507 and r22. I see that some countries are going to co2 as a refrigerant. Any issues with those high pressures? As far as a/c goes 410 is the new one with 407c as the new 22.
