How Seawater Dispersant SWD Works
Marine seawater cooling systems are continuously exposed to microorganisms and marine organisms. If biological growth attaches to heat-transfer surfaces, it can restrict seawater flow and reduce heat-transfer efficiency.
RXSOL Seawater Dispersant SWD works by dispersing marine growth and reducing its adhesion to seawater heat-transfer equipment. Regular treatment helps maintain cleaner heat-transfer surfaces and supports stable cooling performance.
Pre-Cleaning Requirement
If a seawater cooling system is already heavily fouled, the existing deposits and marine growth should be removed before beginning a preventive SWD treatment program.
Note that the dispersant is intended to prevent new growth and does not replace the cleaning required to remove established fouling.
Important Application Precaution
Seawater Dispersant SWD should not be dosed while seawater is being drawn as make-up water for an evaporator or water maker.
The evaporator/water maker should be isolated or shut down during dosing and for at least 30 minutes after dosing.
Seawater dispersant is available in 25-liter containers (PCN 5148409).For vessels which operate continuously in coastal waters,
we recommend dosing every three days. For all oceangoing vessels, we recommend dosing every two days while in coastal waters and at a minimum dose of once a week when not. Seawater dispersant should not be fed to a system while the seawater is being drawn as makeup for an evaporator or water maker. Either isolate the evaporator or shut it down while Seawater dispersant is being dosed and for at least 30 minutes afterward.
