Now that's precision. Do you laypeople wonder why some parts cost a million dollars or more? It's not the cost of the material, it is the incredible engineering, the very expensive CNC machines, and extremely smart and talented engineers involved, to make that part what it is. I was engaged in the installation, maintenance and repair of screw compressors, but I have never seen the current size as in the video at 2:23 and did not even think that there are current sizes, like it. We installed 6. 120 ton 134a screw machines at Radford studios in 1999 - 2001. Incredible machines but had to be in biomass to avoid huge start up tax during the day. in order to cycle the machines and never shut down had they built a capacitive reactive unit.To avoid the tax on start up was not cost effective. I wonder how they feel about that now 2 decades later?
