Flameproof Motor Package for PDH Unit at a Petrochemical Base in East China

Background: A large East-China petrochemical enterprise built a new propane dehydrogenation (PDH) unit where process media are flammable/explosive, so every driven device must meet strict flameproof and continuous-operation requirements.

Challenge: Compressors and pumps face complex duties—motors need Ex d flameproof protection and VFD speed control to match process flow, while minimizing energy use and lifecycle maintenance cost.

Solution: XIMA supplied YBX5 flameproof ultra-high-efficiency motors for standard pumps and YBBP flameproof VFD motors for compressors; units comply with GB3836 and Ex d certification at IP55/IP56.

Engineering & service: XIMA’s team performed on-site duty surveys and selection calculations, offered prototype tests and batch delivery, and committed to 24/7 full-process accompaniment to shorten commissioning.

Outcome: After commissioning, system efficiency rose ~12% vs the prior scheme with significant annual electricity savings and long-term "zero-fault" operation—solid backing for the client’s safe, low-carbon production.
