Background information

Hebei Hanlan Environmental Technology Co., Ltd. successfully exported 88 dedicated Low-Noise Muffler for MTU 16V 2000 Series diesel generator sets to Republic of Cuba with each unit supporting up to 2500kW, for the important peak regulation power plant construction project in the country. This project is a customized noise control solution for high-power MTU units, demonstrating the strength of Chinese manufacturing in international high-end power equipment supporting sectors.

Low-Noise Muffler Core Parameters
▸ For: MTU 16V 2000 Series
▸ Unit Power: 2500kW (Aggregate: 220MW for 88 units)
▸ Speed: 1800rpm
▸ Displacement: 76.3L
▸ Exhaust Temp. Range: 400-750°C

Project Highlights
1.Outstanding Noise Reduction Performance
▸ Utilizing absorber and reflector combined silencer technology, achieving 27dB theoretical noise attenuation (exceeding the 25dB contractual requirement), effectively reducing noise impact on surrounding environments.
▸ The absorber section consumes sound energy via the friction of porous absorber, while the reflector section reflects sound waves through impedance mismatches in ducts, utilizing dual-mechanism to ensure noise control effect.
2.High-Reliability Design
▸ Material: 316/316L stainless steel for the main part, with high-temperature resistance (400-750°C) and corrosion resilience performance, adjusted to Cuba’s tropical rainforest climate.
▸ Structure: With reinforced ribs, wind-resistant anti-tear brackets (60mm×60mm square tubing), and flared end caps for stress reduction, ensuring a long-service stability for container rooftop-mounted.
▸ Process: Double-sided welding with consistent bead control, compliant with JB/T9869-1999 and some other industry standards.
3.Customized Solution
▸ 1-to-1 matched to MTU 16V diesel generator set (1800rpm, 76.3L displacement), strictly keeping backpressure <3kPa to preserve power efficiency.
▸ Designed with backpressure monitoring ports, drain ports and perforated silencing baffles (1.5mm thickness, 2mm aperture) for operation and maintenance needs.
4.Scalable Delivery Capability
▸ Efficient production and on-time delivery of 88 mufflers, demonstrating Hanlan’ s large-scale customized supply ability.

Customer Value
▸ Environmental Compliance: Reducing noise pollution significantly, assistanting the power plant passes the international environmental standards.
▸ Operational Efficiency & Stability: Low-backpressure design minimizes the affect on generator performance, extending serve lives of equipments.
▸ Full Lifecycle Support: 12-month warranty with installation guidance and technical support, ensuring risk-free operation and maintenance.
