In 2026, a well-established plastic packaging manufacturer in Pakistan—active in the industry since 1991—launched a production upgrade project and introduced ZOZEN’s 3 million kcal/h gas and oil thermal oil boiler. In key processes such as melting, casting, stretching, drying, and heat setting of polypropylene and polyethylene materials, a stable and precisely controlled high-temperature heat source is essential for ensuring product quality and production capacity.

ZOZEN 3 million kcal/h gas and oil thermal oil boiler

Compared with conventional steam systems, thermal oil boilers offer:

uniform heat delivery across the heating system

precise temperature regulation over a wide range

relatively low operating pressure for given temperatures

suitability for continuous process production

For these reasons, a 3 million kcal/h gas and oil thermal oil boiler is particularly aligned with the needs of film, textile, chemical fiber, and plastic processing enterprises.

ZOZEN solution: tailored capacity and fuel flexibility

After a rigorous technical selection process, the Pakistani client introduced a YQW series dual-fuel thermal oil boiler from ZOZEN Boiler. The selected model provides a rated thermal power of about 3 million kcal/h, enabling stable supply of high-temperature heat transfer oil to multiple production lines simultaneously.This offers several advantages directly related to the customer’s real production needs:

1. Appropriate output

   The capacity of 3 million kcal/h delivers sufficient high-temperature medium for continuous operation, supporting large-scale plastic packaging production without thermal shortages.

2. High-temperature working performance

   The boiler is designed for operating temperatures up to around 320°C, with a working pressure up to 1.0 MPa, meeting the requirements of plastic processing stages that demand steady high heat.

3. Dual-fuel flexibility

   The boiler can burn natural gas or heavy oil and switch between them when needed. For enterprises exposed to variable fuel price trends or supply uncertainties, this 3 million kcal/h gas and oil thermal oil boiler provides strong operational resilience and economic initiative.

4. Industry applicability

   It is particularly suitable for chemicals, chemical fiber, plastics, textile and film production—industries that rely on continuous, precise high-temperature heat sources.

Supporting steady quality and efficient production

In daily operation, steady heat supply is fundamental to achieving stable product quality. By delivering continuous circulation of thermal oil with controlled temperature, the 3 million kcal/h gas and oil thermal oil boiler helps the client maintain consistent processing conditions.

This supports:

stable thickness of film materials

improved molding quality

reduction of scrap rates

smoother line operation

The dual-fuel feature not only enhances supply security, but also allows enterprises to select fuels based on local availability and economic considerations. For manufacturers facing complex market conditions, this capability makes the 3 million kcal/h gas and oil thermal oil boiler*both a production tool and a strategic asset.

Conclusion

The successful application of ZOZEN Boiler’s 3 million kcal/h gas and oil thermal oil boiler in the Pakistani plastic packaging industry shows how advanced thermal oil technology directly meets real manufacturing needs. With appropriate capacity, precise high-temperature performance, and flexible fuel options, this solution helps enterprises enhance operational stability, reduce energy costs, and strengthen long-term competitiveness while supporting efficient, safe, and high-quality production.
