The Test Bed: Dongfang Turbine Opens a 50 MW Compressor Test Platform at Deyang
Dongfang Turbine's large compressor test platform entered service at Deyang on 15 October — a three-rig facility anchored by a 50 MW twin-drive open test bed, described as the country's first of its kind.
Lead
Dongfang Turbine Co., Ltd.'s large compressor comprehensive test platform entered service at Deyang, Sichuan, on 15 October 2026, Sichuan Daily's Chuanguan News (川观新闻) reported — a facility the developer describes as the country's first electric-motor twin-drive compressor test platform.
Facts
The facility. The platform combines three test rigs: a 50 MW twin-drive open test bed — described as the country's largest of its kind — able to test large axial compressors and gas-turbine compressors, with gearboxes on either side of the motor covering both high-speed/low-torque and low-speed/high-torque duties; a 10 MW test system aimed at natural-gas pipeline transmission, carbon capture and storage, and supercritical-CO₂ power applications; and a basic-research rig for impeller development. (Sources: Chuanguan News, 2026-10-17; the Deyang Daily's account carried by the developer's group.)
The stated role. The platform integrates basic research, prototype validation and factory acceptance testing in one site, and is described as closing the design–manufacture–test–validation loop for the developer's compressor line. Factory tests to international standards can be run on it before delivery. (Source: the same.)
A note on the superlatives. The developer's own account calls the 50 MW rig the country's largest electric-motor twin-drive test platform; the newspaper's report calls the platform the country's first electric twin-drive compressor test platform. We record both phrasings as published. (Sources: the same.)
The track record cited. The coverage lists the developer's compressor deliveries across five fields: a trunk-line unit at the Shangluo station of the West–East Gas Pipeline, a gas-turbine boosting unit at a Huaneng power plant, the Mulei compressed-CO₂ storage project, a thermal-battery storage design, and a steam-compression retrofit EPC.

Note on sourcing. This item reports government-media and developer accounts of an industrial facility entering service. We record the verifiable layer — the date, the rigs and their stated capabilities. Superlatives are reported as published, and we do not rank or recommend suppliers.
What the source does not state
The reports do not state the platform's construction cost or timeline, the test accuracy or instrument specification, whether it takes third-party test work, or which international test standards it will work to in practice.
