Conveyor grease is rarely one problem. There is the lubrication the belt needs to run, the process residue that lands on frames and guards, and the oil film that collects dust until walkways and equipment housings turn dark and slippery. Steam is worth testing on that second and third group because it swaps mechanical scrubbing for heat and pressure. The honest answer to the question in this title is yes for many factory conveyor jobs, with limits you should confirm on your own line before you budget for equipment.
Where steam earns its keep on a conveyor
Grease softens as it heats. On a chain, sprocket or frame coated in a mix of lubricant and particulate, a jet of high-temperature steam lifts the softened layer off the surface, so the operator spends less time with a brush and a scraper. On open frames, guards, drip trays and the underside of transfer points, that matters because the surface geometry is awkward and hand scrubbing slows the whole shutdown window.
The second benefit is volume. A cleaning job during a planned stop competes with maintenance work for the same hours. If your crew can clean a section of conveyor framework in the time they used to spend on one bay, you either finish the shutdown early or you clean more of the line in the same shift. Test that on your own equipment with a stopwatch rather than accepting a vendor claim.
Dry steam and wet steam are not the same job
Machines that switch between dry and wet steam give you two different tools. Dry steam is lower in moisture, so it carries heat into the soil and leaves the surface nearly dry; it suits electrical housings, control cabinets' outer panels, and areas where you do not want standing water. Wet steam carries more water with it, which helps flush loosened residue away from a frame or a tray. A fixed industrial steam cleaning equipment setup that offers both modes lets an operator match the mode to the surface instead of changing machines mid-shift.
Pressure and temperature set the ceiling on what the machine can do. On the PowerDe HW02 fixed unit, for example, the published parameters include 160° steam temperature, 0.8 MPa vapour pressure, 6 kW heating power and an 80 L SUS304 tank, with a 220 V supply. Take those numbers as a reference point for what to ask any supplier, and confirm the figures for the model you are actually quoted.
Where steam is the wrong first choice
Run the list of exclusions before you buy, because this is where most failed trials come from:
- Bearings and gearbox seals. A direct jet aimed at a seal can push water and loosened grit past it. Clean around the seal, then relubricate to the maintenance schedule.
- Belts and belts that carry product. Steam can drive moisture into belt edges, splices and pulley faces, and residue that ran off the belt can end up where product touches the line.
- Anything electrical that is not sealed for washdown: junction boxes without a suitable enclosure rating, cable glands, encoder and sensor connectors, fans.
- Bearing steels and carbon-steel frames left wet. Steam condenses; if the surface cannot be dried, plan for a corrosion protection step afterwards.
- Food-contact and open processing areas, where moisture during a cleaning cycle plus runoff has to be controlled and validated by your own hygiene programme.
- Insulation, lagging and hollow sections where steam can enter a cavity and stay there.
Preparation decides whether the trial succeeds
Lock the conveyor out and confirm it cannot be started from another station. Cover or bag motors, drives, sensors and cable entries that will be near the work. Put a containment plan under the section you are cleaning: loosened grease and runoff have to be captured, not left to travel to a drain or into the next bay. Dry the section afterwards and relubricate what the cleaning removed. If your site keeps a written kitchen cleaning process review discipline for hygiene areas, use the same approach here: one written method, one operator check, one sign-off.
On the utility side, check what the machine needs before it arrives: an 80 L tank and a 6 kW heating load are a different conversation from a 4.5 kW battery-powered hand-pushed unit. Confirm supply voltage and phase, the breaker rating, water supply and fitting size, hose reach, and whether the crew can move the machine to the far end of the line without a second person.
Mobile or fixed: match the machine to how you clean
A fixed unit makes sense where cleaning happens at one station or in one bay on a schedule, with water and power already there. A mobile steam cleaning machine makes sense when conveyor lines are spread across a plant, when you clean along aisles, or when the crew needs the machine to follow the maintenance work. Some hand-pushed and driving-style units run on battery, which solves the cable problem in narrow aisles but adds run time, charging and spare-battery planning to the job.
Compare the two by asking your supplier for a trial on your own line, on your own dirtiest section, with your own operators. That single test settles more questions than a specification sheet.
Chemicals, water and the trade-off you are making
Teams move to steam because they want to cut detergent use, cut the rinse water that follows detergent, and reduce the scrubbing labor that nobody wants to staff on a night shift. Steam still leaves you with wastewater containing the removed grease, so your disposal route does not change just because the cleaning agent changed. Some heavy, polymerised deposits still need a detergent step or a mechanical step either before or after steam. Keep that in the plan so the trial is not judged on the assumption that one process removes everything.
How to run the trial so the numbers hold up
Pick two comparable sections of the same conveyor. Clean one with your current method and one with steam, and record four things: minutes of operator time per section, whether the target soil was removed without hand scrubbing, how much drying time the section needed, and anything the steam affected that you did not intend to touch. Note the water the machine consumed and whether the crew had to refill mid-job.
Run the same test twice, because a first pass is usually a learning pass. If the steam side wins on time and on soil removal with no collateral problems, you have a business case written by your own crew. If it does not, you have avoided a purchase and you know which part of the process failed.
What to ask a manufacturer before you sign
Working with an intelligent cleaning equipment manufacturer that also builds production and process equipment usually changes the conversation from catalogue models to fit. Ask three questions in writing:
- Which published parameters were measured, and can they be witnessed or documented for the unit you are buying?
- What protection functions does the machine have, and how are they verified at commissioning — leakage, short-circuit, high temperature, high voltage and water-shortage protection are all listed on PowerDe cleaning models.
- Who supports commissioning when the plant is not next door to the factory, and what spare parts ship fast enough to keep a cleaning shift running.
If your line has a layout that no standard nozzle reaches, that is a customisation question rather than a product-selection question, and it is worth raising in the first call instead of after a quotation.
Bottom line
Steam will not lubricate your conveyor and it will not replace every cleaning step. On frames, guards, drip trays, housings and other hard-to-scrub surfaces coated in softened grease, it usually reduces operator time and scrubbing effort while cutting the detergent and rinse water that the old method carried with it. Whether that holds on your line is a two-section trial with a stopwatch, not a specification comparison. Run the trial, write down what your crew saw, and buy against your own numbers.
