MTC-X Mobile Fuel Polishing System – Portable 1,560 GPH Diesel and Bio-Fuel Tank Cleaner with Multi-Stage Bag Filtration and Dual Fine Filters

The MTC-X is a purpose-built mobile fuel polishing system designed for maintenance teams that need to service diesel and bio-fuel storage tanks at multiple locations without fixed infrastructure. Powered from a standard AC mains outlet and mounted on a wheeled cart for unrestricted site mobility, the system draws fuel through a two-stage cleaning circuit — a high-capacity bag filter vessel for bulk water and sludge removal at the primary stage, followed by dual spin-on fine filters for precision particulate and water separation downstream. With a 26 GPM / 1,560 GPH flow rate, the MTC-X can process over 12,400 gallons in a standard eight-hour maintenance window. Its fine filter bypass mode, manual additive injection, filter drain and purge capability, locking cam and groove connections, and built-in spill containment tray are all engineered for efficient, safe, and cost-effective fuel maintenance work in marine, industrial, and standby power environments.

• Multi-Stage Bag Filtration at 26 GPM / 1,560 GPH: The MTC-X processes diesel and bio-fuel through a two-stage cleaning circuit at a nominal flow rate of 26 GPM, handling approximately 12,480 gallons in an eight-hour run and over 37,400 gallons across a continuous 24-hour period. The primary bag filter vessel accepts interchangeable filter bags from 1 to 800 microns, enabling the operator to work progressively through coarser to finer micron ratings during Phase 2 recirculation passes to steadily remove large particulate before engaging the spin-on fine filters. Downstream, the dual fine filter housings accept 3, 10, or 25 micron fine filter cartridges or 3 and 10 micron water block elements, providing absolute-rated filtration to achieve the fuel cleanliness levels required for diesel injection system protection. This combination of adjustable primary filtration and precision secondary filtering makes the MTC-X adaptable to tanks ranging from moderately contaminated to heavily fouled without requiring a separate machine for different contamination levels.
• Portable Cart-Based Design for Multi-Tank Site Servicing: Built on a robust wheeled cart with a push-handle frame, the MTC-X enables maintenance personnel to reposition the entire polishing system between fuel tanks at a site without lifting equipment or fixed connections. All system components — the 3/4 HP pump, primary bag filter vessel, dual fine filter housings, vacuum and pressure gauges, water level sight glass, valve manifold, hoses, and spill containment tray — are integrated into a single compact unit measuring approximately 48 inches tall by 22.5 inches wide. The 25-foot clear suction hose and 25-foot discharge hose provide sufficient operational reach to access tanks in confined plant rooms, belowdeck marine compartments, and ground-level storage yards, allowing a single MTC-X unit to service multiple tanks during one maintenance visit.
• Locking Cam and Groove Connections for Fast, Secure Hose Management: All fuel port connections on the MTC-X use industrial locking cam and groove couplings — 1.5-inch diameter on the suction inlet and 1.25-inch on the discharge outlet — providing tool-free, leak-resistant hose connection at each tank service location. The locking mechanism holds hoses securely during operation while the pump generates full suction vacuum and discharge pressure, preventing uncontrolled hose separation that could cause fuel spills or personnel exposure. The 1.5-inch clear suction hose allows the operator to visually confirm fuel flow and pump prime status throughout a polishing run, while its larger bore supports the system's full 26 GPM throughput without generating excessive inlet restriction that could load the pump or trigger false vacuum gauge readings.
• Spill Containment Tray with Integrated Safety Monitoring: The MTC-X incorporates a built-in spill containment tray beneath all filter housings, valve connections, and draining points, capturing incidental fuel releases during hose connection, filter changes, and drain procedures — a critical safeguard in areas where fuel spills create safety, environmental, or regulatory compliance concerns. Operator awareness during polishing runs is supported by a water level sight glass on the front of the primary bag filter vessel, which gives continuous visual indication of accumulated water buildup so the operator can drain the vessel before water saturation affects downstream filter performance. Vacuum gauges on the primary filter vessel and pump provide real-time suction-side monitoring, while individual pressure gauges on the fine filter housings display element loading and trigger replacement before system pressure reaches the pump protection threshold of 20–25 PSI.
• Fine Filter Bypass Capability for Phased Polishing and Extended Filter Life: The MTC-X features a diverter ball valve that routes fuel exclusively through the primary bag filter, completely bypassing the dual fine filters during the initial bulk removal phases of a polishing cycle. This bypass mode is essential when working on tanks with heavy water, sludge, or coarse particulate loads — conditions where immediately engaging the spin-on fine filters would cause rapid element loading and premature replacement well before meaningful tank cleaning has been achieved. By systematically reducing contamination burden through bypass operation in Phases 1 and 2, the operator preserves the fine filter elements for Phase 3, where absolute-rated filtration is applied to bring residual particulate and water content down to the cleanliness codes that bulk-only polishing cannot achieve. This phased approach significantly lowers the per-tank cost of fine filter consumables.
• Filter Drain and Purge Capability for Clean Servicing: The MTC-X is equipped with a dedicated primary filter drain valve and a fine filter purge function operated through the accessory selector switch. The primary filter drain valve allows the operator to discharge accumulated water and sludge from the bag filter vessel without shutting down the system, keeping the primary stage clear during extended polishing runs on heavily contaminated tanks. The fine filter purge function — activated by turning the accessory selector to the VAC position — creates a vacuum on the fine filtration circuit that draws residual fuel out of the spin-on filter housings prior to element replacement, reducing fuel spillage and waste during filter changes. Both functions contribute to a cleaner, safer maintenance process and help extend the effective service life of filter elements by preventing premature saturation from accumulated water.
• Manual Additive Injection for In-Line Fuel Treatment: The MTC-X includes a built-in manual additive injection system operated through a dedicated accessory selector switch positioned below the primary filter vessel. When the selector is moved to the INJ position during an active polishing run, the system generates a suction vacuum on the accessory hose that draws fuel treatment additives — such as biocides, stabilisers, or combustion improvers — directly from an external additive container into the fuel circuit, distributing the treatment evenly throughout the tank volume as polishing continues. Additive injection rate can be controlled by partially closing the inlet ball valve to increase available vacuum draw, and dose monitoring is performed visually by observing the additive container level. Once the required quantity has been introduced, the selector switch is returned to the OFF position to resume normal polishing without further modification to the system setup.
