A cleaning trial is the fastest way to judge whether steam cleaning belongs in your maintenance programme. Photographs and spec sheets can show what a machine is capable of, but only a test on your own equipment shows how it handles the grime you actually deal with. Before we schedule a trial, the following information helps us match the right PowerDe cleaning equipment to the job and set measurable pass criteria.
1. The zones and equipment to be cleaned
List every zone in scope: assembly lines, CNC machine cleaning areas, conveyor frames, hydraulic power packs, tooling racks, floors, walls, or service vehicles. For each item, note the make, size, and how exposed it is — enclosed machine housings, open frames, and areas near electrical panels all need different handling. Tell us which zones are critical to production so we can plan the trial around the shortest possible downtime window.
2. The soil being removed
Describe the contamination rather than just the surface: cutting oil and coolant residue, way-oil film, hydraulic fluid, graphite dust, welding spatter, food grease, or a mixture. State how long the soil has been in place, since a week-old oil film and a baked-on quarter-year deposit call for different steam settings and dwell times. Photos of the worst-case and typical cases let us prepare the matching nozzle and high-pressure steam cleaning machine configuration in advance.
3. Utilities available on site
Confirm the power supply at each trial location. Our PowerDe HW02 steam cleaner runs on 220 V with 6 kW heating power, an 80 L SUS304 tank, and a tap-water inlet with a 4-point internal-tooth (1/2 inch) joint, so it needs a standard 220 V supply and a water connection. Battery-driven models such as the HMW3 series are the option where power or water is limited. Also tell us about drainage, floor slope, and whether wash-water recovery is required by your site rules.
4. Constraints and safety requirements
Send your electrical protection rules, permitted water-pressure limits near control cabinets, required lockout/tagout steps, PPE standards, and any restrictions on runoff. Note sensitive components nearby — bearings, belt drives, sensors, and open connector boxes — so the trial uses dry steam where moisture must be limited and wet steam where flushing is needed.
5. Your acceptance criteria
Agree on what “clean” means before the machine arrives: visual removal of visible soil, time allowed per machine, number of operators, and how the result will be inspected. Include the target cycle time per zone and the crew size you can commit. We compare the trial result against those numbers rather than against a general claim, so you get a decision you can defend internally.
6. Trial logistics
Finally, provide the site address, the responsible contact, available trial dates, and access times outside production shifts. If your operation runs in batches, tell us which changeover window we can use — most factory maintenance zones are best trialled during a planned break so the result is measured against a normal restart.
With these six items we can arrive at the trial with the correct machine, nozzles, and settings, and leave you with a documented result instead of an estimate. Send the zone list and soil photos to our team, and we will propose a trial date and the steam cleaning machine we recommend you test.
