Looks like this is a "done deal" for you - the correct way is to consult with quality before such purchases are made to ensure expensive mistakes are not made & if this isn't already within your quality procedures it might be an idea to add this requirement it so decision makers are aware that they should consult before purchases are made?
However as long as
the equipment contains no chemicals that should not be in contact with food (supplier should be able to provide this information)
the equipment is easily cleanable/sterilised and can be swabbed to show this
the equipment condition is monitored so that any damage doesn't contaminate food
I can't see an auditor raising objections (as you'll have proof that equipment is suitable?)
