When you compare commercial steam cleaning equipment, two specifications decide how well a machine will actually clean: the temperature at which it generates steam, and the pressure at which it delivers that steam to the surface. PowerDe's cleaning equipment listings do cover both, but the information is spread across category pages and individual product pages. This article explains exactly what the product listings disclose about steam pressure and temperature, and how to read those figures when you are specifying a machine for a real job.
Where pressure and temperature information appears
At the category level, the listings describe machines in qualitative terms. The hand-pushed and fixed models are described as high-temperature, high-pressure machines with dry and wet steam modes, while the driving-style models are described as offering dry steam, wet steam, and hot water modes. These descriptions tell you the class of machine, but not the numbers.
The specific figures appear on individual product detail pages. The most complete example in the current catalog is the PowerDe HW02 steam cleaner, whose detail page publishes a full parameter table.
The figures published on the HW02 detail page
For the fixed HW02 model, the listing states the following parameters:
- Steam temperature: 160 °C
- Steam pressure: 0.8 MPa (about 8 bar)
- Heating power: 6 kW
- Water tank: 80 L, SUS304 stainless steel, with a tap-water inlet
- Working voltage: 220 V, with dry steam, wet steam, and an integrated vacuum cleaner
What do these numbers mean in practice? A generation temperature of 160 °C is well above the 100 °C boiling point of water at atmospheric pressure, which means the boiler produces superheated steam under pressure. When that steam reaches a surface, it releases considerably more heat than boiling water would, and that heat is what loosens hardened grease, oil, and baked-on soil without chemical detergents. The 0.8 MPa stored pressure is what drives the steam through the hose and lance, keeping the jet strong enough to push into seams, wheel arches, and engine-compartment crevices rather than dissipating at the nozzle. The 6 kW heater and 80 L tank determine how long the machine can hold that temperature and pressure before it needs a refill, which matters for gas-station and parking-lot operations where several vehicles are cleaned in sequence.
What the mode descriptions tell you
Alongside pressure and temperature, the listings distinguish operating modes, and this is where the steam information becomes actionable:
- Dry steam carries little free moisture, so it suits surfaces where standing water is a concern. The hand-pushed HMW3 listing, for example, describes cleaning and disinfecting hospital beds and medical machinery with dry and wet steam.
- Wet steam carries more moisture and heat directly into heavy soil, such as vehicle exteriors and floors.
- Hot water mode, listed on the driving-style PWD01, PWD02, and HMW2 models, adds a rinse function for indoor garages and narrow outdoor parking spaces.
Several listings also note leakage, short-circuit, high-temperature, high-voltage, and water-shortage protection. These are the safeguards that keep the boiler within its rated temperature and pressure range during normal use, so treat them as part of the pressure and temperature story rather than as separate features.
What the listings do not state
Not every model page publishes figures. The fixed HW03 and the hand-pushed HMW3 listings describe high-temperature, high-pressure performance without giving temperature or pressure values, and one listing shows a model-name inconsistency between "HW03" and "PowerDeHMW3 (220V)". If you need verified figures for a tender document or a compliance file, request the parameter sheet from the manufacturer before relying on those pages. You can browse the full range, including the pages that do publish parameters, in the PowerDe steam cleaning machine section.
How to use this information when comparing machines
- Open the product detail page and check whether it states steam temperature and pressure as actual numbers, not just the phrase "high temperature, high pressure".
- Match the mode to the job: dry steam for water-sensitive equipment, wet steam for heavy soil, hot water mode where a rinse is required.
- Check tank capacity, tank material, and working voltage against the conditions at your site, since these determine how long the stated temperature and pressure can be sustained.
- Where figures are missing, contact the supplier at sales@powerde.net and ask for the confirmed parameter sheet before you commit.
In short, the listings give you a workable starting point: category pages identify the class of machine, and detail pages such as the HW02's provide the concrete steam temperature and pressure you need for comparison. Where a page stops at qualitative wording, treat the numbers as unconfirmed and ask for them directly.
