The 450XL compressor is so versatile it can handle almost any refrigeration system condition. The complete line of 450XL compressors is comprised of six models ranging from a nominal 25-ton 2-cylinder machine all the way to the 200-ton 16-cylinder model. Other offerings include 4, 6, 8 and 12-cylinder mid-size units. All 450XL compressors run at a maximum of 1200 RPM, and all are provided with built-in capacity reduction steps for economical operation at reduced loads.
Rated Conditions of 10F Evaporators and 95F CondensingVer característicasView Features
Top End
Suction and discharge porting achieves minimum pressure drop with valve plates
Spring loaded safety heads relieve internal cylinder pressure if subjected to an incompressible fluid
Three compression rings and a single, special oil scraper ring for keeping oil consumption to a minimum
Piston and Connecting Rod
Piston and connecting rod assembly allows for movement only between the connecting rod bushing and piston pin
