Product Center-Changzhou Dinglong Environmental Protection Equipment Co., Ltd.

Providing energy-efficient, environmentally friendly equipment and integrated solutions.

Product Line

The equipment operates at high speed and with exceptional stability, supporting a wide range of coating processes, including solid-color, metallic, and wood-grain finishes. Color-coated steel sheets are extensively used in architectural exterior walls, roofing, appliance panels, and interior decoration. Production trials conducted by customers in more than 20 countries worldwide have validated the equipment’s reliability and durability.

Building materials and home appliance color-coated production lines

Employing advanced galvanizing technology, the equipment delivers outstanding corrosion resistance of the base material with uniform treatment, providing high-quality base materials for building structures, automotive components, and general machinery. The equipment is energy-efficient and environmentally friendly, with low operating costs, thereby meeting the requirements of modern green manufacturing.

Galvanizing Production Line

Utilizing precision roll-coating technology, this equipment delivers highly accurate coating-thickness control and is well-suited for applications such as tinplate coating, electronic-component enclosures, and gift packaging. The system is compatible with a wide range of coating processes, operates with exceptional stability, enables rapid color changes, and can meet the demands of multi-variety, small-batch production—having already been extensively validated in the packaging and printing industry.

Tinplate and Aluminum Sheet Coating Production Line

Specializing in interior coating and drying of can bodies, our system achieves 100% coating coverage with no dead zones, ensuring the safety of the contents. Paired with a highly efficient, energy-saving drying system that delivers precise temperature control, it meets the stringent requirements of food and beverage cans as well as chemical containers. Our equipment has been deployed by renowned can-manufacturing companies both domestically and internationally, earning market recognition for its stable performance and reliable quality.

Two-piece and three-piece can internal coating and drying production line

This system employs a three-bed regenerative thermal oxidation technology, achieving VOC removal efficiencies of over 99% while delivering stable and reliable operation. It is ideally suited for treating medium- to high-concentration exhaust gases in industries such as petrochemicals, packaging and printing, pharmaceuticals, and automotive coatings. With its high heat recovery efficiency, the equipment significantly reduces operating costs, enabling customers to simultaneously meet environmental compliance requirements and achieve economic benefits.

Three-bed RTO

Test Information

Innovative rotary valve design features a compact structure, minimal footprint, and heat recovery efficiency exceeding 95%. It is ideally suited for large-scale continuous-production facilities in industries such as surface coating, packaging printing, and automotive painting. The equipment operates smoothly, requires simple maintenance, and represents the optimal solution for treating high-volume exhaust gases.

Regenerative Thermal Oxidizer (RTO)

Specifically designed for 24-hour continuous production industries, this system employs multi-chamber continuous switching technology to ensure uninterrupted exhaust gas treatment. With a thermal efficiency exceeding 96%, it delivers stable and reliable operation, meeting the stringent standards of high-demand sectors such as chemicals, pharmaceuticals, and petrochemicals. The equipment features comprehensive safety protection and is capable of handling industrially complex exhaust gases with diverse compositional profiles.

Continuous RTO

The preferred solution for large-volume, low-concentration exhaust gases. A zeolite rotary concentrator first concentrates the low-concentration exhaust into a high-concentration, small-volume stream, which is then fed into an RTO for efficient oxidation, significantly reducing operating energy consumption. This technology is widely used in workshops for home appliance coating, automotive painting, and electronic manufacturing, making it a cost-effective and efficient environmental control solution.
