A Packaging Company Purchases RTO for the Third Time
In May 2024, a packaging materials company in Kunshan, Jiangsu, made its third purchase of Yurcent's RTO, reinforcing its commitment to sustainable production after years of proven success.
Project Background
The Kunshan-based company, with 30+ years in flexible packaging printing, specializes in high-barrier, multi-functional films and materials. Its products—including plastic printed bags and films for food, daily goods, and pet food packaging—are exported to 100+ countries.
In 2019, to drive green transformation, the company partnered with Xi'an Yurcent Environment Technology Co., Ltd, to treat VOC emissions from its printing workshops using RTOs.
Key Results After 4 Years:
- Stable VOCs emissions ≤30 mg/m³ (real-time monitoring)
- Two-phase RTO installations (2019 & 2023)
- Third purchase in 2024, citing reliability and efficiency
Emission Sources & Composition
- Sources:7 printing machines + 2 laminators
- Total flow rate:100,000 m³/h
- Key solvents: Ethyl acetate (64%), propyl acetate (31%), isopropanol (5%)
- Ink solvents: Isopropanol, ethanol, butanone, PMA (~10%)
- Theoretical VOC concentration:2,500–4,000 mg/m³
Design Highlights
- Two 50,000 m³/h Rotary RTOs
- Phase I (2019) and Phase II (2023 "Jinding" series)
- Flexible operation: One or both RTOs can run based on production demand.
- Energy Recovery
- Waste heat generates steam for drying inks/films, cutting energy costs.
- Emission Control
- "Reduced airflow + increased concentration"retrofits optimize RTO efficiency.
Why the Client Chose Yurcent Again
✅ Proven stability: Phase I RTO ran 4+ years without downtime.
✅ Ultra-low emissions: Consistently ≤30 mg/m³, exceeding local standards.
✅ Energy savings: Steam reuse reduces 20%+ thermal energy costs.
✅ Compact & smart: 3rd-gen RTOs save space and integrate IoT monitoring.
Client Testimonial
"Yurcent’s RTOs solved our dual challenges—emission compliance and energy costs. Their reliability made the third purchase an easy decision."
