BKG® Screen Changers (formerly Xaloy®)


Contamination of the melt steam by metal, wood, paper or internally generated black specks yields products that are unacceptable in appearance and/or performance. We supply a range of screen changers - manual, hydraulic and continuous - ensuring a clean melt stream.


BKG® NorCon™ EM / EMR Manual Screen Changers

BKG NorCon EM35

From the worldwide leader in filtration equipment, Nordson offers the BKG® NorCon™ EM / EMR (standard) as well as the BKG® NorCon™ XM / XMR (metric) manual screen changers.

Contamination of the melt stream by metal, wood, paper or internally generated black specks yields products that are unacceptable in appearance and/or performance. Manual screen changers are the least expensive and most suitable option for processes that require infrequent changes. Manual screen changers minimize costly downtime for screen replacement. With a simple swing of the handle lever during routine shutdown, clean screens are quickly brought on-line. No line disconnection occurs, and full production is re-established. The EM/EMR can easily be retrofitted with a ratchet that is mounted to the top.
