HZLX-96 ASTM D96 Crude Oil Centrifuge Tester
Product Overview
The HZLX-96 Oil Centrifuge Tester is a high-performance, microprocessor-controlled laboratory centrifuge engineered for the separation, purification, and analysis of transformer oil and other insulating liquids. Driven by a brushless DC motor and equipped with a swing-out rotor (4 × 100 mL capacity), the HZLX-96 delivers a maximum speed of 2,000 rpm and a maximum RCF of 957 × g, making it the ideal instrument for dissolved gas analysis (DGA) sample preparation, sediment separation, and quality control testing of dielectric fluids.
With a touch-sensitive LCD control panel, bilingual Chinese/English interface, 100 programmable presets, and a temperature-controlled chamber (ambient +10°C to 80°C), the HZLX-96 combines laboratory precision with industrial durability. Its integrated safety system - including overspeed protection, imbalance detection, door lock interlock, and automatic error diagnostics - ensures safe, worry-free operation in high-throughput testing environments.
Product Value
Accurate Oil Quality Assessment: Centrifugation is an essential pretreatment step in transformer oil testing - removing free water, sludge, and suspended particles before dielectric strength, interfacial tension, and dissolved gas analysis - ensuring downstream test results are not compromised by sample contamination.
Regulatory Compliance: Meets the sample preparation requirements of ASTM D3612 (DGA), IEC 60422 (oil maintenance guide), and GB/T 7595 (in-service transformer oil quality) for centrifuged oil samples.
Lab Efficiency: 100 user-programmable presets eliminate repetitive parameter entry; the memory function restores the last-used settings on power-up, and the automatic lid opening feature streamlines high-throughput workflows.
Built for Endurance: The 70 kg heavy-duty chassis, brushless motor (maintenance-free), and industrial-grade components ensure years of reliable service even in continuous-use testing labs.

FAQ
Q1: What is its purpose in oil testing? Pre-treats oil before BDV, DGA, moisture tests.
Q2: How to balance samples and save presets? Pairs ≤2g difference. Save up to 100 presets.
Q3: RPM vs RCF? Which timing mode to use? RPM = speed; RCF = g-force. Use Time at Set Speed.
Q4: What temperature for oil centrifugation? 20–40°C standard. 40–60°C for waxy oils. Max 80°C.
Q5: Common errors and maintenance tips? E9=imbalance. Clean & lube rotor. Call for E7/E14.
