Facing the long and severe winter climate in Northern China, the reliability and energy efficiency of heating systems are crucial. This gallery showcases several central heating project sites in Northern China, all of which have selected the SZS series gas-fired hot water boilers manufactured by ZOZEN Boiler as their core heat source. As a key product of ZOZEN Boiler, the SZS series features a double-drum longitudinal layout and a large furnace design, combined with low-nitrogen combustion technology. This not only effectively reduces NOx emissions but also ensures high-efficiency conversion of thermal energy. With excellent product quality and comprehensive after-sales service, ZOZEN Boiler delivers continuous and stable warmth to thousands of households during the cold winter, becoming a trusted partner for many heating enterprises.
ZOZEN Boiler recently supplied three sets of 70MW hot water boilers for a large-scale central heating project. Utilizing cutting-edge technology, these boilers aim to provide efficient and consistent heating for a widespread residential area. The successful implementation of this project has not only enhanced the quality of life for residents but has also cemented ZOZEN Boiler's reputation for expertise in delivering large-scale heating solutions.
Thermal oil heaters are widely used in chemical industry, printing and dyeing, edible oil processing and other industries because of their low pressure, high temperature and precise temperature control. ZOZEN gas-fired thermal oil heater adopts multi-loop round coil structure, with large heat exchange area, high thermal efficiency and fully automatic and safe operation.
Shenyang Third Thermal Heating Co., Ltd. is one of the largest companies of the central heating industry in Shenyang. The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency.
Relying on the industry-university-research cooperation and large-scale production, ZOZEN has manufactured more than 400 varieties of specifications of industrial boilers including gas-fired boilers, coal-fired boilers, biomass-fired boilers and thermal oil heaters.Develop up to now, the annual production scale of ZOZEN has exceeded 2,000 sets and 25,000 tph.
