The revised EN 13053:2019 introduced a new rule for construction and cleaning requirements of plate heat exchangers. Members of the Eurovent Product Groups ‘Energy Recovery Components’ are of the opinion that the new rule might be misleading and constrain application of plate exchangers. With this position paper addressed to members of the Eurovent Product ‘Air Handling Units’ and experts of CEN TC 156 WG 5, manufactures of heat exchangers intend to provide an explanatory note on correct interpretation of new requirements.
