Daoyunai D919 UV CIPP Equipment All-in-One Integrated Design for Sewer Repair

Precision Below Ground: Integrated UV Curing System Ships to Global Partners

Six Daoyunai UV Curing Systems are on their way to our customers this month

We are thrilled to announce a significant milestone: the first six units of our Daoyunai UV Curing Systems will be manufactured, tested, and then shipped to our pioneering customers this month!

Unmatched Performance for D919 CIPP Lining Applications

The Daoyunai D919 is not a generic curing unit. It is a fully integrated, precision-engineered solution optimized for curing resin-saturated liners within a 200mm to 2000mm inner diameter, directly addressing the critical needs of the D919 standard.

Key Features & Technical Advantages:

Rapid, Uniform Curing: Our high-intensity, strategically positioned UV lamps ensure a complete and consistent cure throughout the liner in a single, continuous process. This eliminates cold spots and delivers a fully structural, monolithic new pipe with superior mechanical properties.

All-in-One Integrated Design: The system combines the power unit, winch, and curing frame into a single, robust platform. This streamlined setup drastically reduces deployment time, minimizes on-site equipment footprint, and simplifies operation in confined sewer environments.

Intelligent Process Control: An integrated PLC with a remote monitor provides real-time data on curing progress, UV intensity, and winch speed. This guarantees a verifiable, repeatable cure every time, ensuring compliance with project specifications.

Robust & Reliable for Demanding Sites: Built with hardened materials and sealed components, the D919 is engineered to withstand the harsh conditions of underground construction, including moisture, dust, and physical impact.

Enhanced Operational Safety: Features include automatic shutdown protocols, thermal overload protection, and emergency stop systems, prioritizing crew safety during critical curing operations.

This shipment is just the beginning. We ramp up production to meet the global demand.
