ZOZEN WNS series steam boiler builds health and safety defense line for Hydron Contact Lens

After more than 30 years of development, Wuxi Zozen Boilers Co., Ltd. has made outstanding achievements in various industries. Recently, the ZOZEN WNS series gas-fired steam boiler has established a high-temperature sterilization safety line for the production of contact lenses, which has promoted the healthy development of the entire industry.

Contact lenses are lenses that are worn on the cornea of the eye to correct vision or protect the eyes. The production of contact lenses mainly uses polymer monomer injection mold filling. After a series of production processes such as mold clamping, curing molding, demolding and hydration, qualified products will enter the product packaging line and then be subjected to high temperature sterilization. The steam boiler plays an irreplaceable role in this link.

In 1995, Gingco International Gropu acquired Hydron Company and obtained professional technology and equipment, and officially established Hydron Contact Lens Co., Ltd., which is mainly engaged in the production and processing of contact lens and care solutions. Facing the growing market demand, Hydron made an important decision to introduce multiple contact lens production lines. At the same time, the introduction of steam boilers with excellent energy saving and environmental protection performance was also included in the procurement plan.

ZOZEN achieved cooperation with Hydron Contact Lens Co., Ltd.

After rigorous market research and analysis, Hydron Contact Lens chose ZOZEN as its heat source equipment supplier to provide sufficient high-temperature steam for the high-temperature sterilization process in the production of contact lenses. According to the actual demand of Hydron, ZOZEN technical team designed the efficient WNS series gas-fired steam boiler system for it.

The large-diameter corrugated furnace of ZOZEN WNS series gas-fired steam boiler not only eliminates the influence of thermal stress on the furnace body, but also ensures the full combustion of fuel. With advanced low NOx burners, NOx emissions can be as low as 30mg/Nm³, which is a typical energy-saving and environmentally friendly product of ZOZEN.

At the same time, in order to reduce the loss of exhaust gas and make full use of the latent heat of vaporization of the flue gas, ZOZEN also equipped energy-saving devices such as the  condenser at the end of the flue to reduce the exhaust temperature to 60℃ and increase the boiler thermal efficiency to over 98 %.

In order to make Hydron's production line more intelligent and efficient, ZOZEN adopts PLC intelligent control system. The various protection functions such as over-temperature, over-pressure, water shortage, leak detection, flameout, etc., ensure the secure and stable operation of the boiler.
