METClean XL Multi+

Who the XL Multi+ is for

The XL Multi+ is the large-format METClean platform for heavy-duty, fleet, plant and agricultural workshops. Filters from trucks, buses, tractors and plant are longer and heavier than car and van filters, and they need a working space and handling that a car-sized cabinet can’t give.

It suits a business that cleans heavy-duty filters regularly, either its own fleet’s or as a service to operators nearby. Control is through a PLC with an operator panel (HMI), so the cleaning programme runs the same way whichever technician loads the machine.

The XL Multi+ is also presented as a multi-service machine, and the supplied demonstration film shows other components being cleaned as well as DPFs. Each of those services is still being confirmed for this model, so buy it for heavy-duty DPF work and treat the rest as something to check with us.

• A garage that cleans only car and van filters, where the S or the E is a better fit for the space and the price.
• Cleaning from a van. The V is the METClean designed around a vehicle installation.
• A workshop without the space, power or lifting arrangements to handle large filters safely.
• Filters that are cracked, melted or otherwise damaged. Cleaning removes ash and soot; it doesn’t repair a substrate.

METClean S

Your work is car and light commercial filters and you want automatic cleaning, a pressure pre-test and a printed record in a smaller cabinet.

METClean E

You clean car and van filters only, on a tighter budget, and simple analogue control with a cold-air purge is enough.

Filters and parts it takes

The XL Multi+ is built for large-format diesel particulate filters from HGVs, buses, plant and agricultural machinery. The filter connects to the stainless braided wash hose at its outlet through an adaptor, so water runs through it against the normal exhaust direction, and a pneumatic clamping ram holds it in the chamber facing away from the door.

Heavy-duty filters vary widely in length, diameter and fittings, and some arrive with pipes, brackets or sensor cables attached. Send us the filters you see most often, or bring one to a demonstration, and we’ll confirm how it is held and connected. The confirmed vehicle classes for this model are awaiting approval.

The component types below are those shown for the XL Multi+. Each service and its programme is awaiting confirmation for this model.

A normal job, start to finish

The sequence below follows the METClean XL operating instructions, which MET uses for the XL Multi+ until a dedicated manual is published. Times and settings are adjustable on the operator panel; MET’s recommended values are covered in training.

1. Check the machine. Power and compressed air connected, the tank full and the machine level. The filter shouldn’t be heavily contaminated with oil or coolant before it goes in.
2. Inspect and lift. Check the filter for cracks, melting or oil soaking and work out its exhaust flow direction. Move heavy-duty filters with suitable lifting equipment, not by hand.
3. Connect and clamp. Fit an adaptor to the filter outlet, secure any pipes and cables, and clamp it to the braided wash hose. Position the filter by the clamping ram, lock it with the toggle lever facing away from the door, and double-check it is secure.
4. Pre-test. Air is passed through the filter to give a back-pressure reading of the filter as it arrived: the before figure for your customer or fleet record.
5. Close and clean. Close the pneumatic door with the two-handed control, then start the automatic clean: prewash, main wash and high-pressure impact. An audible alert and a flashing beacon signal the end.
6. Dry. Swap from the wash hose to the drying hose and run the hot dry, with adjustable time and temperature. A cold-air purge also clears residual water at the end of the cycle.
7. Test, print and return. A final reading gives the after figure, and the printout records your company, the technician, the customer and the filter’s serial number. Lift the filter out and refit or return it.

Throughput depends on the programme you run, how loaded each filter is, and the time spent lifting and connecting large components. Cycle duration isn’t published while MET confirms measured profiles, so plan capacity with us from your own fleet or customer mix.

A heavily saturated filter, mainly a combined DPF and catalyst, may not dry fully in the machine; the instructions say it then needs a drying oven or a driving cycle on the vehicle. For a fleet, the useful question is how many filters you need back in service each week, and whether spare filters on the shelf would keep vehicles moving.

Built for heavy components

What the XL Multi+ does at each stage, following the XL operating instructions, and what each result does and doesn’t tell you.

Control

A PLC with an operator panel (HMI) runs the cleaning programme, so each job follows the same sequence whichever technician loads the machine.PLC/HMI

Cleaning

A soft start at low pressure, then the main wash and timed high-pressure bursts through the filter against the exhaust direction. Ash and soot leave with the water into the machine’s filtration.

Drying

Hot drying through a separate drying hose, with adjustable time and temperature, plus a cold-air purge. Some filters still need finishing in an oven or on the vehicle.

Testing and reporting

A back-pressure reading before and after the clean, and a printout with the job details. Readings show change on your machine; they don’t certify a filter.

Other services

The demonstration film shows other components being cleaned. Each service and its programme is awaiting confirmation, so check yours with us before relying on it.
