Hi, everyone!

How to understand ladder equipment? Does it mean a series of equipment?

(The above sentence is extracted from preface of a book about cooling.)

Thank you!

Perhaps a better way to punctuate it:
You have studied the fundamentals and commercial refrigeration system.This final volume deals with another phase of your career ladder – equipment cooling.

The dash keeps "ladder" and "equipment" from being confusingly bolted together by that hyphen. So you end up with the easier "equipment cooling."

The "career ladder" is the imaginary ladder you climb throughout your career, to reach greater responsibility and reward, presumably.

Hm, makes much more sense, Copyright.

Oh, I SEE.

Thank you

You're welcome -- they could just as easily have left "ladder" out of the sentence.

... another phase in your career.
... another step in your career ladder.
