Alfa Laval Replacement Quartz Sleeve Set Part No.594645 81 | 9000738 01Q

Our aftermarket Alfa Laval quartz sleeve replacement set (OEM reference: 594645 81, interchange part 9000738 01Q) is engineered as a direct drop-in spare component exclusively designed to fit original Alfa Laval UV ballast water treatment UV reactors, serving as the core protective UV quartz sleeve for UV lamp assemblies onboard marine vessels. Precision manufactured to match original Alfa Laval dimensional standard, this quartz sleeve for UV lamp perfectly replaces the factory original 594645 81 quartz sleeve unit, fully compatible with mainstream Alfa Laval BWTS medium-pressure amalgam UV lamp disinfection systems widely installed on bulk carriers, container ships, oil tankers and offshore working vessels.

Features of Fiver Ultraviolet's UV Quartz Sleeve 594645 81

1> 100% OEM Compatible Replacement – Exact match for Alfa Laval part number 594645 81 and alternative code 9000738 01Q. This standard Alfa Laval quartz sleeve features identical dimensional specs, mounting positions and sealing sizes, enabling plug-and-play replacement without reactor modification or pipeline adjustment.

2> High-Purity UV Transmittance Performance – Made of premium fused quartz material, this professional UV quartz sleeve achieves ultra-high UVC transmittance, effectively stabilizing UV disinfection intensity. It avoids light attenuation caused by aging or fouled original sleeves, ensuring the BWTS system meets IMO D-2 ballast water discharge standards continuously.

3> Perfect Protection for UV Lamp – Specially designed as a dedicated quartz sleeve for UV lamp in Alfa Laval UV reactors, it completely isolates high-temperature UV lamps from corrosive seawater, preventing lamp cracking, burnout and mercury leakage caused by thermal shock and water impact during long-term marine operation.

4> Marine-Grade Durability & Anti-Fouling Property – Optimized uniform wall thickness delivers excellent thermal shock resistance, adapting to global variable seawater temperatures. The super-smooth surface resists marine scaling, biofouling and sediment adhesion, perfectly matching the reactor’s automatic wiper system for long-term stable operation.

5> Stable & Long Service Life – Anti-UV aging and anti-yellowing material formula prevents gradual light transmittance decline under long-term high-intensity UV irradiation. Effectively reduces frequent replacement frequency and lowers ship maintenance and operating costs.

6> Complete Set for Direct Installation – This Alfa Laval quartz sleeve set comes with matched sealing gaskets and accessory parts as original OEM configuration, fully meeting onsite ship repair and dry dock maintenance requirements, supporting fast installation and vessel quick return to service.

7> Strict Quality Inspection – Every UV quartz sleeve is inspected for no bubbles, no micro-cracks and consistent light transmittance, strictly complying with marine BWTS system operating standards, suitable for container ships, bulk carriers, tankers and other commercial vessels.
