Shengyan SCQ-Filtration Cartridge Ultrasonic Cleaner

Overview

The Shengyan SCQ-Filtration Cartridge Ultrasonic Cleaner is an industrial-grade, application-specific ultrasonic cleaning system engineered for the rigorous decontamination of filtration media—including pleated polypropylene, PTFE, stainless-steel sintered, and titanium filter cartridges—commonly used in pharmaceutical, biotechnology, food & beverage, and fine chemical manufacturing. It operates on the principle of acoustic cavitation: a 28 kHz high-power ultrasonic generator drives piezoelectric transducers bonded to the tank base, inducing controlled cavitation in aqueous or solvent-based cleaning solutions. This generates transient micro-jets and localized shockwaves (>1000 atm) capable of dislodging sub-micron particulates, biofilm residues, organic fouling, and inorganic scale from complex geometries—including blind holes, pleat crevices, and tapered end caps—without mechanical abrasion or dimensional alteration. Unlike general-purpose cleaners, the SCQ series integrates dual-phase process logic (cleaning + reverse-flush cycling), enabling automated, repeatable regeneration of critical filtration components per validated cleaning protocols.

Key Features

• High-intensity 2500 W ultrasonic output at 28 kHz—optimized for low-frequency penetration into dense, high-aspect-ratio filter structures
• Electropolished SUS316L stainless-steel tank interior—resistant to corrosion from aggressive cleaning agents (e.g., alkaline detergents, citric acid, hydrogen peroxide)
• Precision digital controller with independent parameter memory: ultrasonic power (%), temperature setpoint (°C), and total cycle time (min)
• Dual-mode timer: single-stage duration or programmable alternating cleaning/reverse-flush sequences with audible completion alert
• Integrated 3000 W SUS304 heating system with PID-regulated temperature stability (±1.5 °C) across 0–80 °C range
• Comprehensive safety protection: over-temperature, over-current, over-voltage, and low-water-level interlocks with LED status indicators
• Sound-dampening hinged lid with gasket seal—reduces ambient noise to ≤65 dB(A) during operation
• Manual inlet/outlet valves compatible with standard 1/2″ NPT fittings for integration into closed-loop rinse systems

Sample Compatibility & Compliance

The SCQ-Filtration Cartridge cleaner accommodates cylindrical filtration elements up to 20 inches (508 mm) in length and standard threaded end fittings (e.g., 222, 226, DOE). It supports filter media with nominal pore ratings from 0.01 µm to 50 µm—including depth filters, membrane filters, and sintered metal cartridges. The system meets structural and material requirements outlined in ISO 13485 for medical device reprocessing equipment and aligns with Good Manufacturing Practice (GMP) Annex 15 validation principles for cleaning process qualification. While not inherently FDA 21 CFR Part 11 compliant (as it lacks electronic audit trail functionality), its operational parameters are fully documentable via external data loggers for IQ/OQ/PQ execution. All wetted surfaces comply with USP Class VI biocompatibility standards for stainless-steel alloys.

Software & Data Management

The SCQ series employs embedded microcontroller firmware—not PC-based software—ensuring deterministic real-time control and immunity to OS-level vulnerabilities. All operational parameters (power %, temperature setpoint, elapsed time, fault codes) are displayed on a high-contrast 4-digit LED interface with non-volatile memory retention. For traceability, users may record batch-specific settings manually or integrate optional RS-485/Modbus RTU output (available upon request) to connect to SCADA or MES platforms for centralized logging. Process documentation complies with GLP and ISO/IEC 17025 requirements when paired with calibrated external thermometers and power analyzers.

Applications

This system is routinely deployed in regulated environments for: pre-use sterilization assurance of vent filters; post-process cleaning validation of bioreactor air/gas filters; recovery of high-value ceramic crossflow membranes; and routine maintenance of HVAC HEPA pre-filters in cleanrooms. Additional applications include degassing of viscous polymer solutions prior to casting, dispersion of nanomaterials in suspension media, and cell lysis in preparative microbiology workflows. Its 112 L capacity enables simultaneous processing of multiple large-diameter cartridges (e.g., 10″ × 40″ housings), reducing turnaround time versus benchtop units.

FAQ

What filter lengths and connection types does the SCQ-Filtration Cartridge model support?

It accommodates cartridges up to 508 mm (20 inches) in length with standard 222 or 226 sanitary thread connections.

Is the 28 kHz frequency fixed, or can it be adjusted?

The operating frequency is fixed at 28 kHz—selected for optimal energy transfer into high-mass, low-porosity filtration substrates.

Can this unit be integrated into an automated clean-in-place (CIP) skid?

Yes—manual inlet/outlet valves allow connection to external pumps and fluid handling systems; optional analog I/O modules support PLC interfacing.

Does the unit include validation documentation or IQ/OQ templates?

Factory calibration certificates are provided; site-specific IQ/OQ protocols must be developed per user’s quality system requirements.

What cleaning solutions are recommended for pharmaceutical-grade filter regeneration?

Validated formulations include 1–2% w/v sodium hydroxide (for organic removal), 0.5–1% w/v citric acid (for inorganic scale), or 3–5% v/v hydrogen peroxide (for microbial load reduction)—all compatible with SUS316L construction.
