We had a pleasant cooperation with ZOZEN. From the design of the boiler system to the manufacturing, installation and commissioning of the boiler, everything was going well. Hope ZOZEN could design and manufacture more boilers with higher efficiency and better performance on environmental protection.
— Libbey (China) Co., Ltd.
Founded in 1818, Libbey Inc. is a large manufacturer of glassware and it is also the standard maker of catering glassware industry in North American. With over 1 billion annual output value, Libbey operates 6 glass manufacturing factories in 5 countries on 3 continents. Libbey (China) Co., Ltd. was set up to develop the Asia-Pacific market. The glass tableware factory located in Langfang Hebei Economic and Technological Development Zone was put into production in early 2007. Its production capacity was up to 100 million per year. As a global company adhering to sustainable development, Libbey decided to update the existing gas-fired boilers to achieve low NOx emissions.
The two sides reached an agreement on boiler selection and cooperation details quickly during the negotiation. Libbey had a deep understanding of the excellent performance of ZOZEN after conducting a field inspection to ZOZEN project site in Hebei. Finally, Libbey purchased the WNS series gas-fired boiler from ZOZEN. Equipped with an advanced low NOx burner, WNS series gas-fired boiler realizes the ultra-low emissions of NOx through smoke recycling technology, which can help Libbey pass the environmental acceptance easily. Meanwhile, the energy-saving devices are equipped at the tail of the flue to reduce exhaust temperature to 60 degrees and improve the thermal efficiency to over 98%.
