Overview
The Deepflow CYASMUVA1 is a dedicated 262 nm ultraviolet (UV-C) lamp module engineered for integration into ultra-pure water (UPW) distribution loops and point-of-use purification systems. Unlike conventional 254 nm low-pressure mercury lamps, the CYASMUVA1 utilizes advanced UV-C LED or excimer-based emission technology to deliver narrowband irradiation centered precisely at 262 nm — a wavelength demonstrating enhanced germicidal efficacy against resistant microorganisms, including adenoviruses and spore-forming bacteria, while minimizing photolytic degradation of critical UPW matrix components such as dissolved silica and trace organic compounds. This spectral specificity supports compliance with stringent semiconductor-grade water standards (e.g., SEMI F63, ASTM D5127) and pharmaceutical water specifications (USP , EP 2.2.43), where residual bioburden control must occur without introducing oxidative by-products or altering resistivity.
Key Features
- Targeted 262 nm UV-C output optimized for high quantum yield microbial inactivation without significant ozone generation or hydroxyl radical formation
- Compact, modular design compatible with standard 1/2″–3/4″ sanitary tubing interfaces (ISO 2852, DIN 11851) for seamless retrofitting into existing UPW recirculation manifolds
- Thermally stabilized optical housing with integrated temperature monitoring to maintain consistent irradiance output across ambient operating ranges (5–40 °C)
- IP65-rated enclosure with stainless-steel 316L wetted surfaces suitable for cleanroom environments (ISO Class 5–7) and GMP-compliant water systems
- Real-time UV intensity feedback via calibrated photodiode sensor, supporting automated dose validation per USP and EU GMP Annex 1 requirements
- Low power consumption (8,000 hours L70) under continuous duty cycling
Sample Compatibility & Compliance
The CYASMUVA1 is validated for use with Type I ultrapure water (resistivity ≥18.2 MΩ·cm at 25 °C, TOC <1 ppb, bacterial count <0.1 CFU/mL) in both laboratory-scale and pilot-scale purification platforms. It meets mechanical and electrical safety requirements per IEC 61000-6-3 (EMC) and IEC 61000-6-4, and its UV emission profile conforms to ISO 15714:2019 for UV disinfection system performance testing. When deployed within a full ultra-pure water system architecture—including pretreatment (RO/EDI), storage (nitrogen-purged tanks), and distribution (polished stainless-steel loop)—the module contributes to achieving FDA 21 CFR Part 11–compliant audit trails when paired with compatible SCADA-level controllers.
Software & Data Management
While the CYASMUVA1 operates as a standalone hardware module, it supports analog 4–20 mA and digital Modbus RTU (RS-485) outputs for integration into centralized water quality monitoring platforms. These interfaces enable continuous logging of UV intensity, cumulative exposure dose (mJ/cm²), lamp-on time, and thermal status—data points essential for GLP/GMP documentation, preventive maintenance scheduling, and regulatory batch record linkage. Firmware updates are performed via secure USB interface; no cloud connectivity or proprietary software installation is required, preserving network isolation integrity in classified lab environments.
Applications
- Final-stage bioburden reduction in semiconductor fab UPW loops prior to wafer rinsing and photolithography tool supply
- Continuous microbial control in pharmaceutical purified water (PW) and water for injection (WFI) distribution networks
- Research-grade water systems requiring non-oxidative sterilization for sensitive analytical applications (e.g., LC-MS mobile phase preparation, ICP-MS calibration)
- Validation support for ISO 14644-1 cleanroom humidification systems using ultrapure water
- Backup disinfection in redundant UPW architectures where redundancy mandates independent kill mechanisms beyond filtration and ozonation
FAQ
Is the 262 nm wavelength commercially available in mercury-vapor lamps?
No — 262 nm emission is not achievable with standard low-pressure Hg lamps (which peak at 254 nm). The CYASMUVA1 employs solid-state UV-C sources (e.g., AlGaN-based LEDs or KrCl excimer emitters) to achieve this specific wavelength.
Does this lamp require quartz sleeves or periodic cleaning?
The optical path uses fused silica with anti-fouling hydrophobic coating; sleeve replacement is not required under normal operation, though visual inspection per SOP every 6 months is recommended.
Can the CYASMUVA1 be used in hot water sanitization cycles?
It is rated for continuous operation up to 40 °C inlet water temperature; it is not designed for steam sanitization (≥80 °C) or thermally aggressive CIP protocols.
How is UV dose validated during qualification?
Dose validation follows ASTM E2479-21 using calibrated radiometers traceable to NIST; validation includes worst-case flow rate, minimum transmittance (UVT), and lamp aging factor (LAF) per ICH Q5C guidelines.
Is third-party certification available for pharmaceutical use?
Yes — optional IQ/OQ documentation packages and FAT/SAT reports are provided upon request, aligned with Annex 15 and ASME BPE-2022 standards.
