Katadyn Micropur Classic MC 50,000P is the commercial maritime industry standard for long-term freshwater preservation. While GNC Marine’s biological range maintains your vessel’s grey and black water systems, Micropur Classic secures your potable water assets directly inside the storage tanks.
Utilizing advanced silver-ion technology, this highly concentrated 500g powder formulation keeps produced (Reverse Osmosis/Evaporator) or bunkered water completely free from bacteria, algae, and biofilm for up to 6 months. Because it is entirely taste-free and odorless, it ensures absolute crew and passenger satisfaction while maintaining strict biological stabilization throughout complex shipboard distribution lines.
Item: 5310
Packaging: 500g
Fully complies with the WHO Guide to Ship Sanitation by providing the mandatory secondary residual disinfectant barrier in water lines.

On high-capacity passenger vessels and cruise liners, the scale of the potable water distribution network is immense. Storing hundreds of metric tons of freshwater creates significant biological stabilization challenges, especially when water temperatures fluctuate within machinery spaces. Katadyn Micropur Classic 500g is engineered to manage these large-volume assets seamlessly. By introducing silver-ion preservation to the ship’s storage tanks, cruise operators and ferry technical managers can completely neutralize the risk of sudden bacterial outbreaks without affecting the taste or odor of the water served to thousands of guests and crew members.
For the mega yacht sector, water quality must remain flawless. Guest comfort dictates that drinking water, galley supplies, and spa facilities must be absolutely pristine, with zero chemical chloramination smells or altered tastes. Katadyn Micropur Classic MC 50,000P delivers exact, taste-free protection. It safeguards large-capacity structural feshwater tanks against algae, coliforms, and biofilm buildup during long periods at anchor or when the vessel is operating in warm Mediterranean or Caribbean climates.
Naval operations demand complete vessel autonomy and maximum infrastructure resilience. In defense environments, freshwater generators (Reverse Osmosis or Evaporators) must be backed up by an unyielding secondary biological barrier. Katadyn Micropur Classic provides naval fleet managers with a ruggedized, long-term stabilization tool. With an exceptional 10-year shelf life in dry storage, these commercial 500g configurations are perfect for strategic naval stockpiling. They ensure that defense vessels can maintain biological water safety for up to 6 months during extended deployments, technical blackouts, or remote operations far from verified shore infrastructure.
The inner surfaces of marine freshwater tanks and extensive piping networks are highly susceptible to the formation of biofilm—a protective matrix where pathogens like Legionella and E. coli reproduce. Standard water filtration or initial UV sterilization cannot prevent re-contamination down the line.
Katadyn Micropur Classic utilizes active silver ions that continuously bind to the cell walls of microorganisms. This action effectively disrupts their enzymatic activity and halts reproduction, keeping the entire internal surface area of your freshwater system bacteriostatic.
