MTC HC-150 High Capacity Mobile Fuel Polishing System – 10 to 150 GPM Dual-Skid VFD-Controlled Diesel Tank Cleaner with Multi-Stage Filtration and SFC80 Smart Safety Alarms

The MTC HC-150 is a purpose-built high capacity fuel polishing system designed for operations that demand maximum-throughput cleaning of large diesel and bio-fuel storage tanks. Mounted on two independently transportable skids for ease of movement between service locations, the system drives fuel through a six-stage cleaning circuit spanning both skid modules. The Pre-Filter Skid handles bulk decontamination through a primary bag filter vessel and dual mechanical water separators, while the Pump Skid takes over for precision polishing via absolute-rated cartridge fine filter vessels and dual inline magnetic fuel conditioners. The SFC80 Smart Filtration Controller provides automated three-channel alarm monitoring, operator indicator displays, and remote pendant control — making the HC-150 a capable and self-protecting system for high-volume fuel quality management at industrial facilities, marine installations, power generation sites, and large-scale commercial tank farms. Locking 3-inch cam and groove inlet connections, a 2.5-inch discharge port, and a 25-foot clear suction hose allow rapid deployment at any site with 480V/3-phase power available.

• 10 HP Sliding Vane Pump with VFD Flow Rate Control — Up to 150 GPM: The MTC HC-150 is driven by a 10 HP sliding vane pump connected to a 480V/60Hz/3-phase electrical supply, delivering a maximum throughput of 150 GPM (567.8 LPM) at full pump speed. Unlike fixed-speed systems, the HC-150 incorporates a Variable Frequency Drive (VFD) controller that allows the operator to adjust pump output across the full range of 10 to 150 GPM by dialling the frequency between 10 Hz and 60 Hz. Flow rate scales directly with frequency at a ratio of 2.5 GPM per Hz, enabling precise control suited to each phase of the polishing cycle — slower speeds during initial water and sludge extraction to minimise tank agitation, progressively higher rates during recirculation and fine filtration phases to maximise throughput efficiency. The sliding vane pump design provides consistent, pulse-free flow under varying differential pressures across the filter stages, supporting stable operation throughout the full polishing cycle.
• Dual-Skid Portable Design for Maximum Site Flexibility: The HC-150 is constructed as two independent skid modules — the Pre-Filter Skid and the Pump Skid — each sharing an identical footprint of approximately 59 × 36 × 45 inches. This dual-skid architecture serves a practical purpose beyond simply housing the system's components: each skid can be transported, positioned, and relocated independently, allowing the system to pass through standard facility doorways, be loaded onto service vehicles separately, and be placed in confined equipment rooms where a single large-footprint unit could not fit. The two skids connect via a suction hose linking the Pre-Filter Skid outlet to the Pump Skid inlet during operation, and disconnecting takes no more time than releasing the cam and groove couplings at each connection point. This portability makes the HC-150 genuinely mobile in the operational sense, enabling a single crew to service multiple tanks at different locations within the same facility or across multiple sites without major handling infrastructure.
• Multi-Stage Fuel Filtration Across Both Skid Modules: Fuel follows a structured contamination-reduction sequence across the two skids. On the Pre-Filter Skid, a primary bag filter vessel equipped with a liner basket accepts interchangeable filter bags from 1 to 800 microns, enabling the operator to match the coarseness of the primary filtration stage to the contamination severity at each phase of the polishing cycle. Progressive reduction in bag micron ratings — from coarse during Phase 1 and 2 to finer ratings as bulk contamination is cleared — ensures that the upstream stages absorb the maximum possible loading before fuel advances to the Pump Skid. There, dual cartridge fine filter vessels accept absolute-rated secondary elements in particulate (2–30µ), water block (10–30µ), or micro-glass (3–10µ) configurations, providing the final, precision filtration step required to bring stored fuel into compliance with injection system specifications and regulatory cleanliness codes.
• Dual FP-90 Mechanical Water Separators with Independent Side Isolation: The Pre-Filter Skid incorporates two FP-90 mechanical water separators — one serving each filter side — positioned between the primary bag filter and the outlet that connects to the Pump Skid. Each separator mechanically extracts free water and accumulated sludge from the fuel stream, directing separated water to dedicated drain valves for controlled disposal rather than allowing it to advance to the secondary cartridge filter stage. Water detection sensor probes inside each separator continuously monitor water accumulation levels and trigger High Water alarms through the SFC80 controller when thresholds are exceeded, initiating automatic pump shutdown before contaminated fuel can reach the downstream filter elements. Butterfly isolation valves on each side of the Pre-Filter Skid allow one separator to be taken out of service and drained during operation without stopping the entire polishing cycle — a significant advantage during extended high-volume polishing on tanks with heavy water ingress where separator servicing intervals may be short.
• Dual LG-X 4000 Inline Magnetic Fuel Conditioners: Every litre of fuel that passes through the Pump Skid flows through two LG-X 4000 inline magnetic conditioners, each installed in series within the secondary filter circuit. The strong magnetic field generated by each conditioner acts on the charge state of hydrocarbon molecules and ferrous micro-particles suspended in the fuel, reducing the tendency of particulate to reagglomerate into new sludge deposits and promoting a more homogeneous, stable fuel condition leaving the system. Over multiple polishing cycles, the conditioning effect supports reduced fouling rates in the storage tank environment itself, as well as on injector tips, fuel filters, and other downstream fuel system components. Because the LG-X 4000 conditioners are entirely passive — containing no moving parts and requiring no external power input — they contribute continuous fuel conditioning to every polishing pass at zero additional operating cost and with no maintenance requirement beyond periodic connection inspection.
• SFC80 Smart Filtration Controller with Integrated Safety and Alarm System: The SFC80 Smart Filtration Controller on the Pump Skid serves as the HC-150's operational brain, managing pump activation through the VFD, monitoring system health across three independent alarm channels, and providing the operator with a clear picture of system status through a PLC with LCD display. Three alarm channels protect the system continuously during operation: the High Water alarm triggers pump shutdown when water sensor probes detect excessive accumulation in either FP-90 water separator; the High Vacuum alarm activates at 16 inches HG on the pump suction side when primary bag filter loading restricts inlet flow to the shutdown threshold; and the High Pressure alarm fires at 22 PSI discharge-side pressure when secondary cartridge filter elements approach saturation. The SFC80's front panel provides a Pump Control Selector Switch for Manual and Remote operating modes, separate indicator lights for system power, pump running status, and active alarms, and an Alarm Reset push button that requires positive operator acknowledgement before the pump can restart after any alarm shutdown — ensuring the polishing cycle cannot resume in a condition that would compromise fuel quality or risk system damage.
• Filter Isolation Capability for Uninterrupted Servicing: Both the Pre-Filter Skid and the Pump Skid are engineered with Side 1 and Side 2 filter isolation, enabling one filter side on each skid to be taken offline for element servicing while the other side continues processing fuel. On the Pre-Filter Skid, independent butterfly isolation valves control flow through each bag filter vessel and water separator pair. On the Pump Skid, dedicated isolation ball valves separate each secondary cartridge filter vessel from the main flow path. This dual-sided isolation architecture means that neither primary bag filter changes nor secondary cartridge replacements require a complete system shutdown, allowing polishing to continue uninterrupted on large or critically important tanks where extended service pauses are operationally costly. When a High Vacuum or High Pressure alarm indicates that a specific filter side requires attention, the operator can isolate that side, service it, and return it to operation — all without stopping fuel flow through the active filter path.
• Remote Pendant Operation for Flexible On-Site Control: When the SFC80 controller's selector switch is placed in AUTO mode, the integrated remote pendant switch allows the operator to start and stop the pump from a distance without returning to the skid-mounted controller panel. This is operationally valuable when the HC-150 is positioned at a distance from the tank access point, when the operator needs to monitor suction hose positioning or observe fuel flow during startup at the tank opening, or when the system is deployed in a confined equipment room where continuous proximity to the Pump Skid controller is impractical during a long polishing cycle. The SFC80 continues to monitor all three alarm channels and execute automatic safety shutdowns independently of the pendant state, providing full protection regardless of the operator's position on site during operation.
• Fine Filter Bypass Capability for Cost-Effective Phased Tank Cleaning: A dedicated bypass mode on the HC-150 routes fuel exclusively through the Pre-Filter Skid's bag filter vessel and dual water separators, completely bypassing the Pump Skid's secondary cartridge fine filter elements. Engaging precision absolute-rated cartridge elements on a tank with heavy free water, sludge, or coarse particulate contamination would cause rapid element saturation before meaningful fuel cleanliness improvement is achieved — generating unnecessary element replacement cost and repeated service interruptions in the early stages of polishing. The bypass mode allows Phases 1 and 2 of the polishing cycle to absorb the worst contamination through the lower-cost bag filter elements and mechanical water separators, dramatically extending secondary cartridge element service life when they are finally engaged in Phase 3. On chronically contaminated large tanks, the economic and operational benefit of this phased approach can be substantial, reducing both total filter element consumption and the number of polishing interruptions per tank cleaning cycle.
• Locking Cam and Groove Connections with Large-Diameter Hoses for High-Volume Throughput: The MTC HC-150's inlet port uses a 3-inch cam and groove connection, and the outlet port uses a 2.5-inch cam and groove coupling — both sized to handle the system's maximum 150 GPM flow rate without generating restrictive pressure drop in the connection hardware. The supplied 25-foot clear suction hose with a 3-inch diameter allows the operator to reach tank bottom access points from a working distance, and the transparent hose wall provides a direct visual check of pump prime status and fuel flow quality during startup and operation. The 25-foot, 2.5-inch discharge hose offers sufficient reach to direct return fuel to the target tank zone without requiring additional hose extensions in most standard tank service configurations. All cam and groove couplings are locking style, resisting accidental disconnection during operation caused by hose movement, pump vibration, or inadvertent contact from site personnel or equipment.
