When selecting UV equipment, focusing only on power and price is far from enough – the core value of the equipment lies in precise light distribution, stable light output, and engineering design suited to your operating conditions. Choosing the right type of supplier is more important than comparing parameters. Ergu Optoelectronics has focused on the UV optics field for fifteen years, positioning itself around four core capabilities: R&D, certification, case studies, and customization. We are not a simple equipment assembler, but a maker of UV optical equipment that solves real problems. From standardized models to on-demand customization, we match different process scenarios with professional optical capability.

With the acceleration of the renovation of 770,000 kilometers of underground pipeline networks in China, trenchless rehabilitation is embracing significant development opportunities. Industry competition is focusing on equipment reliability, ease of use, and timely maintenance. Leveraging fifteen years of UV technology expertise, Ergu Optoelectronics offers two flagship...

Introduction: No excavation, no road closures, no disruption – CIPP UV curing trenchless rehabilitation technology is becoming the mainstream choice for urban pipeline network renewal. Ergu Optoelectronics' trenchless UV curing system consists of four major modules working in coordination: the light chain, cable reel, intelligent control unit...

Thick coatings and dark adhesives/inks often suffer from "surface cured but interior uncured" – the surface is hard while the bottom layer remains tacky, resulting in poor adhesion and easy peeling. Ergu Optoelectronics' fifteen years of industry experience points out that the root cause lies in the exponential attenuation of UV light as it penetrates the coating. There are two types of solutions: multiple thin coats with layer-by-layer curing, which requires no equipment investment but lowers efficiency; or optimizing the light source configuration – for LED, long wavelengths (395 nm/405 nm) can enhance penetration, while mercury lamps, with their broad spectrum and high energy density, are also suitable for thick, dark systems. A mercury lamp + LED combination can leverage the advantages of both. We support sample testing with real measurements to determine the right solution based on data, rather than blindly increasing power.

The 2026 China-Europe Pipeline Engineering and Trenchless Rehabilitation Technology Academic Conference grandly opened in Shenyang. As a technical pioneer in the trenchless rehabilitation field, Dongguan Ergu Optoelectronics Technology Co., Ltd. (hereinafter referred to as "Ergu Optoelectronics") was invited to attend. The company showcased its two core products—the UV Curing System and the Thermal Curing Air Pressure Inversion Drum—gaining significant industry attention.
