Crude Oil Testing Centrifuge DOC-401

It is designed for water and deposit determining in crude oil. It meets the requirements of standard, and makes use of centrifugal separation to determine the water and deposit in crude oil. It is ideal equipment for moisture determining in oil exploration and researching institute.

LED display (by user’s choice) which to show rotor No., speed, time, temperature, RCF, Acc and Dec curve, and trouble information/error code.
Circular heater for fast heating and temperature uniformity realizes the functions of temperature controlling and temperature holding, which meet the requirements for oil industry.
Frequency-conversion motor with high torque is characterized by stable and fast Acc and Dec as well as long service life, maintenance free, low noise for stable operation.
The tube is manufactured by special process, which won’t be broken so easily during operation is widely used in Daqing Oilfield.
Self-diagnosis system can automatically detect the faults of over speed, over temperature, imbalance and door lid interlock, and display the error code on the display screen to improve safety performance.
Simple operation Microprocessor control and touch panel, the speed, RCF, temperature, time and Acc/Dec curve can be set freely. The parameters can be revised during a run for convenient use.

Accurate BS&W Analysis with the Crude Oil Testing Centrifuge DOC-401

Ensure precise determination of Basic Sediment and Water (BS&W) in crude oil with the Crude Oil Testing Centrifuge DOC-401—a rugged, high-speed centrifuge engineered specifically for petroleum laboratories, oil terminals, and upstream production facilities. Compliant with ASTM D96, API MPMS Ch. 10.4, and ISO 9029, the DOC-401 delivers rapid, repeatable separation of water and sediment from crude oil samples for quality control, custody transfer, and pipeline compliance.

Engineered for Petroleum Industry Demands

The DOC-401 Crude Oil Testing Centrifuge features a robust, explosion-proof motor (optional for hazardous areas) and a precision-balanced rotor designed to hold standard 10 mL or 50 mL centrifuge tubes used in BS&W testing. With a maximum speed of 3,000–3,600 RPM (adjustable), it achieves full separation in 10–15 minutes, allowing operators to visually read water and sediment volumes directly from calibrated tubes—per industry-standard procedures.

Compliant with ASTM D96 & API MPMS 10.4 – Validated method for BS&W in crude oil.
High-Speed, Balanced Rotor System – Ensures stable operation and consistent separation at 3,600 RPM.
Explosion-Proof Option Available – Certified for use in Class I, Division 2 hazardous locations (optional).
Digital Timer & Speed Control – Set exact run time (0–30 min) and RPM for method reproducibility.
Stainless Steel Chamber & Safety Interlock – Auto-shutoff if lid is opened during operation.
Compact, Benchtop Design – Fits in field labs, well sites, and refinery QC stations.

Trusted for Custody Transfer and Quality Assurance

BS&W content directly impacts crude oil valuation, pipeline tariffs, and refining efficiency. Even small amounts of water or sediment can cause corrosion, catalyst poisoning, or contract penalties. The DOC-401 enables field and lab personnel to quickly verify oil quality before shipment or processing—ensuring compliance with buyer specifications and regulatory limits (typically <0.5% BS&W).

Built for durability, safety, and ease of use, the Crude Oil Testing Centrifuge DOC-401 is the go-to solution for accurate, on-site crude oil analysis—where every drop counts.

Separate with confidence. Measure with precision. Transfer with trust.
