Deepflow CYN185UV1 Dual-Wavelength UV Lamp (185 nm / 254 nm)

Overview

The Deepflow CYN185UV1 Dual-Wavelength UV Lamp is an engineered ultraviolet irradiation source designed for integration into ultra-pure water (UPW) generation and recirculation systems. It emits simultaneously at two discrete germicidal and photo-oxidative wavelengths—185 nm and 254 nm—enabling both microbial inactivation and advanced oxidation of trace organic contaminants. At 254 nm, the lamp delivers high-efficiency DNA/RNA photodimerization, achieving >99.9% log-reduction of bacteria, viruses, and spores under validated flow and dose conditions. At 185 nm, it generates hydroxyl radicals (•OH) via photolysis of dissolved oxygen and water molecules, facilitating the oxidative decomposition of low-molecular-weight organics—including residual TOC (total organic carbon)—down to sub-ppb levels. This dual-action mechanism makes the CYN185UV1 particularly suitable for semiconductor-grade UPW systems, pharmaceutical water loops (PW/WFI), and analytical laboratory feedwater purification where stringent TOC < 1 ppb and bioburden < 0.1 CFU/100 mL specifications apply.

Key Features

• Dual-emission low-pressure mercury vapor lamp with certified spectral output at 185 nm (ozone-generating) and 254 nm (germicidal), verified per IEC 62471 photobiological safety standards
• Fused silica quartz sleeve optimized for >90% UV transmittance across both wavelengths, including enhanced ozone resistance at 185 nm to prevent sleeve degradation
• Modular in-line design compatible with standard 1/2″–1″ sanitary tubing interfaces (e.g., Tri-Clamp, ISO-KF), enabling direct integration into UPW distribution manifolds or point-of-use purifiers
• Thermally stable housing with passive convection cooling; optional fan-cooled variant available for high-flow or enclosed cabinet installations
• Compliant with electromagnetic compatibility (EMC) requirements per EN 61326-1 for laboratory environments
• Designed for continuous operation under Class 1 cleanroom conditions (ISO 14644-1) with IP54-rated enclosure options

Sample Compatibility & Compliance

The CYN185UV1 operates exclusively within liquid-phase water streams and is not intended for air or surface disinfection. It is validated for use with resistivity ≥ 15 MΩ·cm water (Type I reagent grade per ISO 3696 and ASTM D1193). The system meets functional requirements outlined in USP “Water for Pharmaceutical Purposes” and supports compliance with FDA 21 CFR Part 211 (cGMP) for water system qualification. While the lamp itself is not a standalone medical device, its integration into UPW systems contributes to meeting ISO 14644-1 cleanroom environmental control objectives and supports audit readiness for GLP/GMP inspections. No hazardous substances are emitted during normal operation beyond trace ozone—levels remain below OSHA PEL (0.1 ppm) when installed with appropriate ventilation or catalytic ozone destruct modules.

Software & Data Management

As a hardware-only UV irradiation module, the CYN185UV1 does not include embedded firmware, touchscreen interface, or digital communication protocols (e.g., Modbus, Profibus). Operational monitoring relies on external system-level instrumentation: UV intensity sensors (254 nm radiometers), TOC analyzers, and flow meters integrated upstream/downstream in the UPW loop. Lamp operating hours are tracked manually or via PLC-based runtime counters in the host purification system. For regulatory traceability, users are advised to log lamp installation date, replacement intervals (recommended ≤ 8,000 hours or per manufacturer’s end-of-life validation), and associated TOC/bioburden test results in accordance with ALCOA+ data integrity principles.

Applications

• Final polishing stage in multi-barrier UPW systems for semiconductor fabrication facilities (fab water loops requiring TOC < 0.5 ppb)
• Oxidative pretreatment before electrodeionization (EDI) or reverse osmosis (RO) membranes to reduce organic fouling
• Continuous microbial control in pharmaceutical purified water (PW) and water-for-injection (WFI) distribution networks
• Feedwater conditioning for LC-MS, ICP-MS, and trace elemental analysis to minimize carbon-based background interference
• Research-grade water purification in university core facilities and national laboratories requiring ISO/IEC 17025-compliant water specifications

FAQ

What is the primary purpose of the 185 nm emission?
The 185 nm wavelength photolyzes molecular oxygen (O₂) and water (H₂O) to generate atomic oxygen and hydroxyl radicals, enabling non-thermal oxidation of trace organics—including acetic acid, formaldehyde, and low-MW humic substances—that are otherwise resistant to 254 nm irradiation alone.
Can this lamp be used in air sterilization applications?
No. The CYN185UV1 is engineered exclusively for submerged or in-line aqueous applications. Operation in air would produce excessive ozone concentrations exceeding occupational exposure limits and is outside its qualified use case.
How often should the lamp be replaced?
Lamp replacement is recommended after 8,000 hours of cumulative operation or when UV intensity at 254 nm drops below 70% of initial output—as measured by a calibrated radiometer—whichever occurs first.
Is the quartz sleeve replaceable independently?
Yes. The fused silica sleeve is a field-serviceable component; replacement requires system depressurization, sleeve extraction, and resealing with fluoropolymer gaskets per manufacturer torque specifications.
Does this lamp comply with RoHS or REACH regulations?
Yes. The lamp assembly contains no restricted substances above threshold limits per EU Directive 2011/65/EU (RoHS 2) and Regulation (EC) No 1907/2006 (REACH), with full material declarations available upon request.
