Genuine Danfoss products and counterfeits may look alike on the outside, but inside the differences can be significant. All Danfoss products are built on an impressive platform of knowhow and experience which is why Danfoss products pass the highest quality standards and come with a multitude of international approvals. Counterfeits, on the other hand, are likely to have a number of shortcomings and these may interfere with the operation of an entire system.
