The Multiquip 6004111171 is a genuine OEM Corrosion Resistor Cartridge designed for DCA400SSK, DCA400SPK, and DCA800SSK series ultra-silent diesel generators. As a direct OEM replacement, this cartridge meets Multiquip's original engineering specifications, ensuring the cooling system receives the correct level of corrosion inhibition. It is confirmed for use across multiple DCA-series configurations, including DCA400SSK, DCA400SSK2, DCA800SSK, DCA800SSK2, and DCA400SPK variants.
Key Features
- Genuine OEM Corrosion Protection: — Formulated to deliver the precise inhibitor concentration required by DCA-series cooling systems, preventing internal corrosion that can degrade coolant passages over time.
- Drop-In Cartridge Replacement: — Designed to install directly into the existing filter housing with no adaptation, maintaining the integrity of the cooling circuit on service intervals.
- Broad DCA-Series Compatibility: — Fits DCA400SSK, DCA400SSK2, DCA800SSK, DCA800SSK2, and DCA400SPK ultra-silent generator models, covering a wide range of Multiquip's diesel generator lineup.
- Coolant System Longevity: — A functioning corrosion resistor cartridge actively neutralizes acids and deposits in the coolant, helping extend the service life of the radiator, water pump, and related components.
- Engine Protection During Extended Operation: — Generators running long-duration or standby cycles are especially susceptible to coolant degradation; a fresh cartridge keeps inhibitor levels within the effective range during extended load cycles.
A corrosion resistor cartridge is a serviceable filter element that sits within the cooling circuit and continuously conditions the engine coolant. It works by releasing corrosion inhibitors into the coolant as it circulates, neutralizing the acids and electrochemical reactions that naturally build up over time and cause pitting or scaling inside metal cooling passages. When the cartridge becomes depleted or clogged, inhibitor levels drop, leaving the radiator, cylinder liners, and water pump vulnerable to accelerated corrosion and potential coolant contamination — leading to overheating and costly internal engine damage.
