With the improvement of people's consciousness of environmental protection, the "Green Revolution" has become a global trend. The pharmaceutical industry, a big discharger of pollution, has become the focus again and again, environmental issues have become the tough challenges that most pharmaceutical enterprises must face. Pharmaceutical enterprises have accelerated their green transformation and upgrading to response to the international call of energy conservation, emission reduction and clean production.Steam is an indispensable production condition in pharmaceutical industry, which is mainly used in heating products and sterilizing equipments, thus, steam boilers play an important role in pharmaceutical industry. Obviously, traditional coal-fired boilers are no longer suitable for the green transformation of pharmaceutical companies. Therefore, using environment-friendly boilers has become an important condition for following the path of energy conservation and environmental protection.With the excellent environmental performance and product superiority, the gas-fired (oil-fired) boiler, developed and produced by ZOZEN, has spread its wings in all walks of life, and has become a powerful roll booster for green transformation in pharmaceutical industry.The ZOZEN steam boilers fall into two main categories: WNS series gas-fired fire tube boilers and SZS series gas-fired water tube boilers. Both of these two gas-fired boilers are star products of ZOZEN energy-saving series. Both are equipped with a large volume furnace and an advanced NOx burner imported from Europe to effectively reduce the NOx emission, so the NOx emission can reduce to 80mg, and the NOx emission can even be reduced to 30mg if flue gas recirculation is added. Obviously, the environmental protection effect is very significant.As a boiler manufacturer serving customers with whole heart, ZOZEN also installed air pre-heater, economizer and condenser on the tails of the gas-fired boiler according to the customer's actual situation, which will effectively reduce the exhaust gas temperature below 60℃ and improve thermal efficiency up to 98%.In recent years, ZOZEN gas-fired boilers are exported to over 100 countries and regions all over the world including Vietnam, Thailand, Australia, Russia, Indonesia, etc., and have been highly praised by many enterprises. At the same time, ZOZEN boilers have promoted brand awareness in food, electron, papermaking, tobacco, construction industry and many other industries with excellent product quality and service.Nowadays, vigorously developing environmental protection is both an opportunity and a challenge for ZOZEN. The general manager of ZOZEN expressed that as a leader in Asian boiler industry; ZOZEN would adhere to the innovation and development and make more contributions to the environmental career.
