SCR Systems
SCR (Selective Catalytic Reduction) Systems are pollution control equipment used on ships to reduce harmful emissions from marine engines. Think of them as special filters that clean the exhaust from large ship engines, similar to catalytic converters in cars but much bigger. These systems help shipping companies meet international environmental regulations by converting harmful nitrogen oxides into harmless nitrogen and water. They're becoming increasingly important as environmental rules for shipping become stricter worldwide.
