“Exceptional industrial screw compressor! The CSH7553 triple-cylinder design is noticeably more efficient than standard models. We replaced 4 old compressors with 2 units of CSH7553-70-40P and our energy bills dropped significantly. AIWEI provided excellent technical support throughout the project. Shipping to UK in 23 days. Will definitely order again!”

“The Bitzer CSH7553-70-40P is the best industrial compressor we have ever used! The triple-cylinder configuration runs incredibly smooth and quiet. Installed 2 units in our central refrigeration plant room. Energy savings of 28% compared to our old reciprocating compressors. AIWEI’s price was outstanding — saved over $10,000 vs local distributors. Highly recommended!”
