Customer Reviews

Metallurgy Factory Manager :

We purchased 4 sets of large-flow oil regeneration systems from Beijing Shiyi for our steel rolling hydraulic stations. The equipment runs stably 24 hours a day, keeps hydraulic oil above NAS 7 grade, and our new oil purchase cost has dropped by over 60%. Their engineers offered remote operation training patiently, after-sales response is fast and reliable. Highly recommended long-term supplier.

Heat Treatment Plant Procurement :

Our quenching oil used to get contaminated with carbon black and sludge quickly, causing high workpiece rejection. Shiyi’s mobile oil purifiers and matched filter elements solved this problem perfectly. The filter cartridges have long service life with low replacement cost, and they can customize sizes to fit our old equipment. Professional, trustworthy manufacturer.

Power Plant Engineer:

We ordered vacuum oil purifiers for turbine oil treatment. The whole machine is fully automatic with real-time cleanliness monitoring, easy to operate for our workers. The factory provided detailed installation drawings and lifelong technical guidance. All products passed CE inspection, delivery cycle was much shorter than other Chinese suppliers we contacted before.
