Overview
The Deepflow CYXUVLPA1 is a specialized 262 nm ultraviolet (UV) germicidal lamp engineered for integration into ultrapure water (UPW) purification systems used in analytical laboratories, pharmaceutical manufacturing, and semiconductor fabrication facilities. Unlike conventional low-pressure mercury lamps emitting at 254 nm, the CYXUVLPA1 utilizes advanced UV-C LED or excimer-based technology to deliver narrow-band irradiation centered precisely at 262 nm—a wavelength demonstrating enhanced absorption by microbial DNA/RNA while minimizing photolysis of trace organic contaminants and ozone generation. This spectral selectivity supports higher photolytic efficiency against planktonic bacteria (e.g., Pseudomonas aeruginosa, Escherichia coli) and spores without degrading downstream ion exchange resins or generating measurable ozone concentrations (18.2 MΩ·cm) and total organic carbon (TOC) stability (<1 ppb) of ultrapure water streams.
Key Features
- Monochromatic 262 nm UV-C output with spectral bandwidth ≤ ±2 nm, optimized for microbial inactivation kinetics and minimal water matrix interference
- Compact, modular design compatible with inline mounting in UPW distribution loops (standard 1/4″–3/8″ stainless steel or PFA tubing interfaces)
- Thermally stabilized driver circuitry ensuring stable radiant flux over ambient temperature range of 5–40 °C
- IP67-rated housing constructed from electropolished 316L stainless steel and fused quartz sleeve with >92% UV transmittance at 262 nm
- No mercury content—compliant with RoHS Directive 2011/65/EU and EU REACH Annex XIV restrictions
- Integrated real-time UV intensity monitoring via calibrated silicon carbide (SiC) photodiode sensor with analog 4–20 mA output
Sample Compatibility & Compliance
The CYXUVLPA1 is validated for continuous operation in recirculating ultrapure water systems delivering Type I water per ISO 3696:1987 and ASTM D1193-20. It maintains efficacy across flow rates from 0.5 to 2.0 L/min at nominal system pressure ≤ 6 bar. The lamp is compatible with high-purity materials including PFA, PVDF, and electropolished 316L SS wetted surfaces. System integration supports compliance with USP “Water for Pharmaceutical Purposes”, EP 2.2.43 “Purified Water”, and FDA 21 CFR Part 211.67(a) requirements for water system sanitization controls. Full validation documentation—including DQ/IQ/OQ protocols, UV dose mapping reports (measured in mJ/cm²), and microbial log-reduction verification per EN 14876:2015—is available upon request for GMP/GLP environments.
Software & Data Management
When integrated with Deepflow’s optional AquaControl™ SCADA interface (sold separately), the CYXUVLPA1 enables automated logging of UV intensity, cumulative operating hours, and thermal status. Data export complies with ASTM E2500-13 for equipment qualification and supports audit-ready electronic records aligned with 21 CFR Part 11 requirements—including user authentication, electronic signatures, and immutable audit trails. All operational parameters are timestamped and stored locally on industrial-grade SD card (optional) or transmitted via Modbus RTU/TCP to central MES/LIMS platforms.
Applications
- Final polishing stage in laboratory-scale and pilot-scale ultrapure water systems for HPLC, LC-MS, and ICP-MS feedwater
- Continuous disinfection of recirculating loops in cleanroom water distribution networks (Class A/B/C/D environments)
- Reduction of bioburden in water-for-injection (WFI) storage and distribution systems under pharmaceutical cGMP conditions
- Supplemental microbial control in semiconductor fab UPW lines where TOC minimization and particle-free output are critical
- Validation reference standard for UV transmittance (UVT) and germicidal dose studies per ISO/IEC 17025-accredited test laboratories
FAQ
What is the typical UV dose delivered by the CYXUVLPA1 at 1.0 L/min flow rate?
At 1.0 L/min and standard 0.5 m path length, the lamp delivers ≥ 35 mJ/cm²—sufficient for ≥4-log reduction of common Gram-negative bacteria per EN 14876:2015.
Is the lamp compatible with existing Deepflow ultra-pure water systems?
Yes—the CYXUVLPA1 shares mechanical and electrical interfaces with Deepflow’s AquaPure™ Series UPW platforms (v3.2 firmware and later). Retrofit kits include mounting flanges and signal adapters.
Does the 262 nm output require special quartz sleeves?
Yes—standard fused silica sleeves exhibit reduced transmission below 270 nm; the CYXUVLPA1 uses high-purity synthetic quartz (Suprasil®-grade) with certified 262 nm transmittance ≥92%.
How often must the lamp be recalibrated?
Annual calibration of the integrated SiC photodiode is recommended using NIST-traceable UV radiometers; calibration certificates conform to ISO/IEC 17025:2017.
Can the lamp operate in dry-air or nitrogen-purged enclosures?
Yes—no oxygen-dependent ozone formation occurs at 262 nm, enabling safe use in inert-gas environments without risk of ozone accumulation or material oxidation.
