High-Precision Stirred HTHP Fluid Loss Cell for Dynamic Cement Slurry Filtration Testing

Accurate filtration evaluation of oilwell cement slurries under downhole temperature and differential pressure conditions is vital for preventing gas migration, mud contamination, and formation damage. The Stirred HTHP Fluid Loss Cell (NFSQ Dynamic Series) delivers automated, reliable, and standardized dynamic filtration measurement in strict compliance with API Specification 10 standards.

Engineered with full stainless steel construction, an innovative non-paddle pressurization pathway, and built-in closed-loop oil cooling, the Nithons Stirred Fluid Loss Cell provides cementing laboratories with superior accuracy, reduced maintenance costs, and unmatched operational safety.

Next-Generation Engineering Advantages Over Traditional Fluid Loss Cells

1. Automated Pressure Regulation & Automatic Differential Lock

Unlike traditional dynamic filtration units requiring tedious manual valve adjustments, our system automatically sets and maintains the exact high/low pressure differentials according to pre-configured API temperature profiles. Operators set test parameters directly on the touchscreen, eliminating human error during pressure ramp-ups.

2. Innovative Non-Paddle Pressurization Channel

Conventional dynamic fluid loss cells pressurize directly through the stirring shaft passage, frequently causing cement slurry backflow, shaft blockage, and paddle seal damage. The Nithons Stirred Fluid Loss Cell isolates the pressurization channel from the paddle drive, completely resolving clogging issues and drastically extending paddle service life.

3. Integrated Oil Cooling System (No External Water Source Required)

Equipped with an internal cooling oil reservoir, dedicated circulation pump, and cast-aluminum cooler embedded with stainless steel coils. This closed-loop system delivers rapid post-test thermal dissipation without requiring external tap water lines, completely avoiding copper-pipe scaling, rust, and water pressure instability.

4. Durable Integrated Sintered Mesh Screen

Features an advanced dual-layer sintered screen combining a 325-mesh filtration surface with a 60-mesh high-strength backing screen. The sintered assembly is separate from the retaining ring, preventing screen tearing, lowering routine replacement costs, and making post-test cleanup fast and simple.

5. High-Capacity 450 mL Slurry Cup & Graphite Sealing

Designed with an enlarged 450 mL slurry chamber to minimize the risk of early gas breakthrough during high-volume filtration cycles, ensuring highly repeatable data for slurry research. The coupling head utilizes high-performance graphite seals for robust leak-free operation without frequent teardowns.

6. Ergonomic Bearing Tilt Mechanism with Electromagnetic Lock

The vessel tilting structure incorporates internal load-bearing assemblies and an automatic electromagnetic lock. Technicians can rotate and position the heavy pressure vessel effortlessly with one-touch button release or manual override, ensuring safe and comfortable lab operations.

Intuitive Touchscreen Data Management & Monitoring

The integrated full-color touchscreen interface displays real-time target temperature, ramp rates, pressure curves, heating duration, and filtration volumes at a glance. Multi-parameter alarm thresholds can be customized for time and thermal limits, providing pre-alarm warnings to ensure complete operational safety during unattended testing runs.
