Equipment is singular. It refers to a “set of things”. “All new equipment” refers to a single collection of things, not to more than one equipment.

If someone only needs a hammer, then one says, “Please bring a hammer.” However, if someone is going to need a hammer, saw, square and chisel to complete a task, and everyone knows what is required, it’s simpler to say, “Please bring the equipment.”

These are correct, depending on the subject:
“A worker needs equipment.” (subject = worker)
“The workers need equipment.” (subject = workers)
“The equipment needs cool air.” (subject = equipment)

Thanks a lot, Aaron! Truly appreciate your feedback. I guess it boils down to the context we are referring. In this case, “all new equipment” implies that there is more than one equipment involved, but I can’t put an “s” because equipment does not have a plural form. So, it is still correct to use “need”. If I am referring to one equipment, then it is correct to use “needs”, i.e. …the new equipment needs to be configured for…
