UV•Xchange™ (multiple options)

Product no:

The UV•Xchange™ is a subsea module that prevents biofouling during long-term in-situ deployments. The UV•Xchange™ inhibits marine growth by bathing critical surfaces in ultraviolet (UV) light. Comparative studies show the UV•Xchange™ to be as effective as leading chemical protection methodologies, such as bis(tributylin)oxide (TBT), at eliminating drift due to biofouling in CTDs and multi-parameter instruments. The UV•Xchange™ offers significant advantages over existing biofouling control technologies:

  • No toxic chemicals: This simplifies deployment and maintenance while eliminating environmental damage
  • No moving parts and hence greater reliability compared to wipers and plungers
  • Protects complex and delicate surfaces, for which wipers are unsuitable
  • Adjustable LED sub-modules ensure effective coverage of all critical surfaces, regardless of geometry

Like all other members of the Xchange™ suite of products, the UV•Xchange™ is field-swappable and easily configured to fit the needs of any operation. Installed directly on the end cap of an X•Series instrument, the module can be set to various positions, enabling optimal coverage of any sensors requiring protection. By eliminating biofouling-induced drift, the UV•Xchange™ allows sensors to perform to their full potential on in-situ instruments. Install the UV•Xchange™ on an AML instrument for a high performance in-situ CTD. The UV•Xchange™ can also protect third-party devices: cameras, lights, structures, sensors, etc. Simply install the UV•Xchange™ module on a Micro•X instrument, point and apply power to protect.


  • Environmentally friendly: Does not use chemicals or reactive coatings
  • Reliable: No moving parts, thus no risk of mechanical failure
  • Effectiveness: Range of up to 10 cm
  • Low maintenance
  • Versatile: Attach to a Micro•X instrument to protect any underwater device, including cameras, lights, non-AML sensors and instruments, and much more
  • Non-contact: Will not damage sensitive lenses or other fragile objects requiring protection
