Multiquip 6004111151 Corrosion Resistor Cartridge

The Multiquip 6004111151 Corrosion Resistor Cartridge is a genuine OEM component designed for the DCA-220SSK, DCA180SSK, and DCA-300SSK series super-silent diesel generators. As a direct OEM replacement, this cartridge is manufactured to the same specification as the original part, ensuring a correct fit within the cooling system without modification. Verified fitment extends across the DCA300SSK series, including DCA-300SSK2, DCA-300SSK3, and FEMA-spec variants. Source your replacement with confidence using part number 6004111151 to keep your generator's cooling circuit properly protected.

Key Features

• Genuine OEM Corrosion Protection: — Manufactured to Multiquip's original specification, delivering the correct inhibitor chemistry to protect cooling system metals against scale buildup and electrochemical corrosion.
• Drop-In Cooling System Fit: — Designed to seat directly into the existing corrosion resistor housing on compatible DCA super-silent generators, requiring no adapter or modification to the coolant circuit.
• Broad DCA Series Compatibility: — Confirmed fitment across DCA-220SSK, DCA180SSK, DCA-300SSK, DCA-300SSK2, DCA-300SSK3, and DCA300SSK FEMA-spec models.
• Coolant System Integrity: — A functioning corrosion resistor cartridge actively neutralizes acids and deposits that form in the coolant over time; a depleted cartridge accelerates internal corrosion and can lead to coolant contamination and overheating.
• Critical for Continuous-Duty Operation: — Super-silent generators used in standby and prime-power applications run extended hours; maintaining a fresh corrosion resistor cartridge is a key interval service item to preserve engine and radiator longevity.

A corrosion resistor cartridge is a serviceable filter element installed in the engine cooling circuit of diesel-powered generators. It contains chemical inhibitors that condition the coolant, neutralizing acids, preventing scale deposits, and protecting dissimilar metals — such as aluminum, cast iron, and copper alloys — from electrochemical corrosion. When the cartridge becomes depleted, coolant acidity rises, accelerating internal corrosion of the radiator, water pump, and engine block passages, which can result in coolant leaks, reduced heat transfer, and eventual overheating damage.
