Magnus Solvent Cleaning

Immersion Cleaning with Solvents

Magnus Engineered Equipment has been making agitation immersion cleaning equipment since the 1950’s.  With this long experience, we understand how to manufacture parts cleaning equipment which can handle solvent based cleaning solutions.  The low flash point of many industrial solvents poses a fire risk and the equipment must be designed to both minimize the risk of fire and prevent the spread of fire should one occur.

Magnus equipment is inherently safe; only shop compressed air is used.  Electrical components, electrical enclosures and flammable materials are not utilized as these components would compromise the safety of the equipment.  Components on the cleaning tank are permanently electrically bonded to comply with the NFPA and OSHA requirements and metal-to-metal moving surfaces are eliminated to avoid spark generation.  Should a fire occur, a fusible link reacts and causes the tank lid to automatically close.  This suppresses the flame and minimizes the availability of air which can feed the fire.  Solution filtration is accomplished via the use of a grounded air operated pump which is compatible with the solvent being used.  It’s advisable to utilize an aqueous cleaner where possible, however if the cleaning operation requires a solvent based chemistry, then use equipment which has been specifically designed to handle the solvent chemistry and minimizes the risk and spread of fire.

The ML 2918 cleaning system presented herein is affectionately called a “Senior” as it has been utilized in the cleaning industry for more than 65 years.  The system is suitable for modification for use with solvent based cleaning solutions and is manufactured and supported by MEE in Willoughby, Ohio and spare parts are generally available via next-day delivery.


Operation of the wash tank is conducted via a three-position selector lever on the side of the tank.

    • RAISE : This position will raise the platform.
    • LOWER : This will lower the platform down to “soak” in the lowest position.
    • AGITATION : This will lower the platform and activate the agitation process. Agitation rate is adjustable.
