ZOZEN fully considered the effects of altitude and atmospheric pressure on gas-fired steam boilers when designing the boiler system solution. On the one hand, owing to the decrease of atmospheric pressure, the combustion speed of fuel slowed down. The designers of ZOZEN properly increased the furnace volume and the convective heating surface area to ensure the heat transfer effect. On the other hand, the air volume and pressure should be modified when selecting a burner, which can ensure the boiler output and the thermal efficiency of the entire boiler system.
The three northeast provinces of China are known as the "cradle of industry", and they are also the important market for ZOZEN to cover the whole country. Over the years, ZOZEN has won the recognition and trust of many enterprises in the region with its excellent product quality, excellent boiler performance and perfect after-sales service. The ZOZEN "Quality Miles" return visit of Heilongjiang Station, the service staff would provide after-sales service for Feihe Dairy, Maple Town Hot Spring Resort, Veolia Thermal Power, Coslight Storage Battery and other enterprises.
Feihe (Gannan) Dairy Co., Ltd., located in Qiqihar, purchased several sets of SZS series steam boilers from ZOZEN in 2017,which have been running stably on the production line of Feihe Dairy. The ZOZEN service personnel quickly and efficiently started the work in the boiler room.
Steam boilers, as the essential equipments in the production process of major enterprises, provide heat energy for drying, disinfection, sterilization, distillation and other production processes, and have extensive applications in various industries such as food, papermaking, chemical, tobacco, and construction and so on. A high quality steam boiler has a direct impact on efficient production of enterprise.
ESK Group, one of Indonesia’s biggest paper producers, had cooperated with ZOZEN in 2007, ordering 2 sets of 20 tph coal-fired steam boilers.
On 3rd August 2018, the representative of ESK Group visited our company again. General Manager Mr. Zhang Guoping extended to him a warm welcome on behalf of ZOZEN. The ESK Group representative was coming for negotiation of second cooperation with us. ESK Group needs a 35 tph steam boiler in order to expand their capacity. The ESK Group representative said that they were really satisfied with the first cooperation. Both ZOZEN’s professional pre-sales guidance and devoted customer service have deepened their trust. After many years of operation, the boilers provided by ZOZEN are proved to feature sufficient output, high thermal efficiency and high level of automation, which help ESK Group save their running costs.
