Grease is one of the hardest soils to manage on factory machinery. It traps metal chips and abrasive dust, holds moisture against bare metal, masks hairline cracks and leaks during inspection, and—on process equipment—drifts tolerances and drags uptime down. The problem is not that the grime exists; it is that removing it without chemicals, high water volumes, or long teardowns is difficult. For procurement teams comparing options for a grease-covered plant floor, the goal is to weigh cleaning power, water and detergent load, footprint, and after-sales support against the real machines available. Below is a practical framework for doing that.
Why steam suits grease-covered machinery
High-temperature steam works on grease because heat lowers the viscosity of the oil so it lifts off the surface, while the pressure of the delivered vapor pushes the loosened soil away. In practice, machines such as the high-pressure steam cleaning machine PowerDe HW02 combine 160°C steam at 0.8 MPa with a dry/wet steam selector, a high-pressure water gun and nozzle, and an integrated vacuum function. That combination is useful on mixed soils—fresh grease, polymerized oil films, plus particulate—because an operator can move between loosening, flushing, and pickup without switching tools.
For buyers whose priority is less water and less chemical, the site positions industrial steam cleaning equipment as a way to cut both. A fixed unit fed from tap water, with an 80-litre SUS304 tank and a 6 kW heater on a 220 V supply, suits a fixed maintenance bay where a water line and power are already in place.
Match the machine to the workspace
Grease-covered assets rarely sit in one convenient spot, so the choice between a fixed and a mobile machine is usually decided by layout, not by cleaning strength.
- Fixed units such as the HW02 (roughly 1200 × 800 × 1200 mm including handles) stay at one cleaning or maintenance station and connect to a water line and 220 V power.
- Hand-pushed units such as the HMW3 (about 1150 × 520 × 1030 mm, a 4.5 kW PTC heater, a 50-litre clean-water tank, and 48 V battery power) move between machines across a shop floor.
- Driving-style and mobile units cover vehicles and large walk-up assets at gas stations, parking lots, and fleet bays.
When the same crew services both fixed process equipment and a vehicle fleet, it is worth separating the two duties across models rather than forcing one machine to do both—battery-powered mobile units and mains-fed fixed units have different duty cycles and refill needs.
Safety and protection features to verify
On equipment that heats water to high temperature and pressure, the protection package is a real evaluation item, not a footnote. PowerDe's cleaning machines list leakage, short-circuit, high-temperature, high-voltage, and water-shortage protection; some models also list high-voltage-explosion protection. Confirm in writing which protections a given model carries, how fault conditions are signalled to the operator, and which of them require a service visit to reset.
What to confirm with the manufacturer
Several numbers that drive a buying decision are not printed on the product pages, so ask the vendor directly rather than inferring them:
- For the hand-pushed HMW3: steam temperature and pressure, battery capacity and runtime, charger output, weight, hose and wand lengths, and the accessory list.
- For the fixed HW02: water consumption per hour, noise level, and the exact accessory set included.
- Whether scenario-specific use—CNC and machine-tool degreasing, or commercial-kitchen grease work—is supported on the model you are quoted, since those applications are not yet stated on the current product pages.
If you are sourcing outside the standard catalog, PowerDe also lists customization, OEM/ODM, product development, and hardware testing services, which matters when your grease profile or footprint needs a non-standard configuration. Contact details are on the company's contact page.
A simple evaluation checklist
Score each candidate against the soil and layout you actually have. The short version:
- Grease type and thickness—light film, heavy build-up, or polymerized residue.
- Distance from power and a water line, and whether battery mobility is worth the runtime limit.
- Cleaning, rinse, and pickup method in one pass, or whether you must add a separate vacuum.
- Documented protections and what a fault reset requires.
- Whether the vendor will confirm missing specs in writing and back customization.
Judge a heavy-duty steam cleaning machine by how it handles your grease, your water and power constraints, and how completely the vendor documents the machine. That is what turns a specification sheet into a defensible purchase.
