Are EC motors compatible with hydrocarbon (R290) refrigerants?

Not all EC motors are compatible with hydrocarbon refrigerants. Unada offers "HC compatible" versions of our UC refrigeration fan motors. Per UL requirements, these are “non-sparking,” and approved for use with hydrocarbon refrigerant charges up to 150gm. We also offer ATEX certified (EEx nA IIA T5) versions of UC motors for more safety-critical applications. For help selecting the best motor for your hydrocarbon application, please contact us.
