Hangzhou Derunbao Lubricant Co., Ltd., founded in 1999, is a high-tech enterprise specializing in the research and production of specialty lubricants. During its recent production line expansion, the company faced dual challenges: limited plant space and increasingly stringent energy efficiency standards in Zhejiang Province. To meet these requirements, Derunbao turned to ZOZEN Boiler, which delivered a tailor-made solution—the 4 Million Kcal Gas Fired Thermal Oil Heater from the YQW series. This customized heater not only optimized floor space utilization but also ensured compliance with upgraded Level 2 provincial energy efficiency standards, aligning with the company’s commitment to sustainable development.

ZOZEN 4 Million Kcal Gas Fired Thermal Oil Heater

The 4 Million Kcal Gas Fired Thermal Oil Heater designed by ZOZEN was engineered with Derunbao’s specific site limitations in mind. To maximize space utilization, the ZOZEN team innovatively positioned the air preheater on top of the boiler rather than beside it. This vertical arrangement significantly reduced the system’s footprint, allowing for easier integration into the company’s existing layout while maintaining full functionality. For a growing enterprise with limited plant area, this innovative design addressed one of the most pressing constraints in industrial boiler installation.

Beyond space efficiency, the 4 Million Kcal Gas Fired Thermal Oil Heater delivers outstanding thermal performance. Its advanced two- or three-pass coil structure ensures excellent heat transfer, while the optimized flue gas flow path reduces energy loss. With a thermal efficiency reaching up to 94%, the heater helps Derunbao lower fuel consumption and operating costs. This efficiency not only translates into tangible economic benefits but also supports broader goals of energy conservation and emission reduction, making the equipment a long-term investment in sustainable operations.

Safety and reliability are also central to the design of the 4 Million Kcal Gas Fired Thermal Oil Heater. The system is equipped with multiple protection devices, including flame detection, high and low oil temperature alarms, overpressure safeguards, and emergency shutdown mechanisms. High-quality insulation materials such as aluminum silicate fiber further minimize heat loss while maintaining surface safety. The robust steel frame design ensures stable operation without heat transfer to external support structures, extending service life and reducing maintenance requirements.

Intelligent control further enhances the practicality of the 4 Million Kcal Gas Fired Thermal Oil Heater. With an advanced automation system, operators can monitor and adjust operating parameters such as temperature and pressure in real time. One-button start and stop functions simplify operation, while smart regulation ensures steady output, meeting the precise heating requirements of specialty lubricant production. This high level of automation reduces human error and improves overall safety and efficiency.

Equally important, ZOZEN Boiler backs its products with comprehensive service support. From project planning and solution customization to on-site installation, commissioning, operator training, and long-term maintenance, ZOZEN ensures that the 4 Million Kcal Gas Fired Thermal Oil Heater continues to perform optimally throughout its lifecycle. Rapid response from the after-sales team minimizes downtime, providing client with reliable assurance for uninterrupted production.

In summary, Hangzhou Derunbao Lubricant’s adoption of ZOZEN’s 4 Million Kcal Gas Fired Thermal Oil Heater reflects a forward-looking approach to balancing limited space with high performance and energy efficiency. With its compact design, superior thermal efficiency, advanced safety features, and intelligent control, the heater fully supports the company’s expansion goals and sustainability vision. Backed by ZOZEN’s professional service system, the solution provides not just reliable heat supply but also a foundation for continued innovation and growth in the specialty lubricant industry.
