Johns Manville, a Berkshire Hathaway Company, is a leading manufacturer and marketer of premium-quality building and specialty products, such as fibers, nonwovens and OEM insulation solutions, delivering thermic, acoustical and safety insulation to a multitude of applications. In business since 1858, the worldwide renowned Company has its headquarters in Denver (Colorado) and manufacturing facilities in North America, Europe and China. The nonwoven spunbond mat production line located in Luoyang (Henan province) in China was inaugurated in 2007, in order to support JM’s focus on the Asian, and particularly the Chinese Market.
After having successfully supplied back in 2001 two steam generators with a 87 BHP steam capacity each to the facility in Berlin, CERTUSS was contacted by JM Luoyang again in June 2016 in order to provide an offer for their planned new facility in Luoyang.
The equipment required should supply the production line in the summer months with 14-17 BHP steam 3times/day for ca.2,5 hours each. In the winter months though it should reach the full capacity on a 24/7 basis, as additionally it supplies the heaters with 7 BHP steam continuously. For the equipment a separate room in the facility was foreseen, right next to the heating room.
In addition to the Junior TC 350, CERTUSS supplied a pre-packaged CVE plant, equipped with feed water tank, mixing cooler, steam dryer, fully automatic time dependent electronically controlled softening plant and dosing instrument. Furthermore, Thermotimat TC Plus, LAN interface and message module are likewise fitted. Commissioning took place in February 2017.
Mr. Zhang Xiang Ying, Plant Manager of JM Luoyang:
“We are happy with having chosen CERTUSS for the technology offered, the high safety protection, the easy operation and the energy saving. The best thing is I can set it up for automatic start-up/shut down, automatic start drainage and automatic clarification without need of supervision. As soon as we are ready we will integrate the steam generator to our DCS (Distributed control system)”.
