If the product is intended to be used/marketed solely to operate as a comfort chiller, it is in the scope of Regulation (EU) 2016/2281.
If the product is intended to be used/marketed solely to operate as a high temperature process chiller, it is not in scope of Regulation (EU) 2016/2281 (exempted by Art 1.2(l).
If the product is intended to be used/marketed for dual use i.e. either comfort chilling or high temperature process chilling, it is still a comfort chiller according to Regulation (EU) 2016/2281 and therefore in scope for the requirements related to comfort chillers.
