Our customer wanted us to make a heat exchanger to cool down a Variable Speed Drive 4500 520kVA NEMA type 4 enclosure. This heat exchanger will be enclosed to the enclosure. My question is as this heat exchanger is out of enclosure system, does it need to be NEMA type 4 certified? is there any UL requirement for this kind of product?
or as long as the inlet and outlet of heat exchanger to enclosure properly sealed that is sufficient.
Thank you
