A quotation for industrial steam cleaning equipment usually fails at the information stage, not at the machine stage. Two buyers can send nearly the same enquiry and receive two different answers, because the words "clean the machine" cover very different jobs: removing cutting fluid from a machining center, lifting carbonized oil off a heat-exchanger housing, or wiping dust from the outside of a machine that must stay electrically dry.

As the vendor on the receiving end, we quote machine-tool cleaning equipment for workshops across those cases, and the enquiries that turn into a correct quotation almost always carry the same nine items. This page lists them in the order our engineers ask for them, explains what each one changes in the specification, and shows how a workshop can collect them in a single walk-down. If you send this information with your first message, you should expect a machine selection, a specification sheet, and a price in one reply rather than a long exchange of follow-up questions.

1. The surfaces and the parts that must stay untouched

Start by writing a list, not a description. "Cleaning the machine" is a request that cannot be specified. "Cleaning the cast-iron bed, the ways covers, the chip conveyor and the safety doors, leaving the control cabinet, the linear encoders and the electrical connectors alone" can be specified.

For each surface note three things: what it is made of, how flat or how textured it is, and whether it can get wet. Cast iron, anodized aluminium, painted sheet steel, stainless steel and polymer covers each react differently to heat, pressure and detergent, and a specification designed for one of them can mark up another. Textured or blasted surfaces and deep thread holes hold residue far more stubbornly than a machined face, so they push the specification toward higher steam temperature rather than higher pressure.

Then list the exclusion zone with the same care: motors, drive cabinets, encoder housings, air lines, bearings that are not sealed, and any nameplate or display. Steam under pressure follows every gap. The exclusion list decides whether you need a low-moisture dry-steam configuration, a lance with a narrow nozzle, or a plan in which those parts are covered or disconnected before the wash. We will not price a machine properly without it.

2. The contaminant, in plain language and by name

The contaminant decides the cleaning mechanism, and the cleaning mechanism decides the machine. Cutting oil and cutting-fluid residue wash off relatively easily and respond to hot water. Paste, wax and drawing compound need more heat. Graphite and diamond paste, lapping residue, and the varnish left by a high-temperature oil are harder and usually need saturated steam. Burnt-on oil on a hot housing, and cured sealant, are harder still, and sometimes need a repeat pass with dwell time between passes.

Describe the contaminant in the words your operators use, and say whether it is fresh or has been sitting. "Coolant, wiped weekly" and "oil and swarf baked on during a two-week shutdown" produce completely different specifications. If you know the product name, give it: a supplier data sheet for the oil tells our engineers about viscosity, whether the oil is water-mixable, and whether it emulsifies, which is far more useful than a general category such as "grease".

Also state what else is on the surface besides oil: swarf, abrasive grit, dust from grinding, coolant sludge, rust. Abrasive particles change the sequence, because they need to be lifted before a wipe touches the surface, and they increase wear on hoses, seals and nozzles.

3. Cleaning standard: what "clean" means for your process

Say what the surface has to achieve afterwards, in the language of your own process rather than a marketing word such as "clean". For most workshops the honest answer is one of three levels: visually clean, so the machine can be inspected or repainted; free of slippery oil film, so operators and walking surfaces are safe; or clean enough for a downstream step such as coating, bonding, painting or a dimensional check, where any remaining film changes the result.

A visual-clean job can often be handled by hot water with a lower steam setting. A surface that must be oil-free before coating usually needs dry steam with controlled dwell and a wipe-down, because water-mixable residue left behind will show up as a coating defect later. If your downstream step is a documented one — a painting specification, an adhesive supplier's surface-preparation note — send that document with the enquiry. It removes more guesswork from the quotation than any other single attachment.

4. Machine dimensions, access route and how much can be dismantled

Send a rough footprint for each machine type: length, width and height, plus the height of the tallest vertical panel. Then answer the practical access questions that follow from those numbers.

  • How close can the operator get? A narrow gap behind a machining center limits lance angle and can require a longer wand or a flexible extension.
  • What has to be reached overhead, and can the operator stand on something to reach it?
  • Which panels are removed as part of routine maintenance, and which are effectively fixed? A specification built around "the panels are off" is a different machine from one built around "the panels stay on".
  • How far does the equipment have to travel from its parking position to the machine, and is the route over a floor drain, a ramp, cable trays or a threshold?

For a workshop with several machine types, send the footprint of the largest and the most congested one. Those two drive the choice between a fixed unit that stays beside one machine, a hand-pushed unit that moves along an aisle, and a self-propelled unit that carries its own power supply across a yard or a wide hall.

5. Utilities available at the wash point

This is the section most often left out and the one that most often delays a correct quotation. Please state, for the exact location where cleaning will happen:

  • Electrical supply: single-phase or three-phase, voltage, and the rated current of the nearest available outlet or breaker. A fixed 220V steam cleaning machine with a heating element in the 6 kW class draws far more than a lighting circuit, and an answer of "we have power" does not tell us whether the wash point supports it.
  • Water: is tap water available within hose reach, what is the pressure like, and is the water hard or soft? Hard water affects scale management and the maintenance interval, so tell us your water source; a water report helps if you have one.
  • Drainage: where does the run-off go? Steam cleaning uses far less water than a pressure washer, but a machine bed still sheds oil-emulsion run-off that has to be collected and disposed of according to your site rules.
  • No utilities at all: if the wash point has no power or water, say so. That pushes the selection toward a battery-powered mobile unit that carries its own tank, which changes what we quote.

6. Cycle time, frequency and how many machines

Give us the count and the rhythm: how many machines of each type, how often each one is cleaned, and how much time the cleaning window allows. A weekly shutdown clean of one machining center is sized differently from an end-of-shift wipe-down across a line of twelve machines.

If you have already cleaned a machine by hand or with another method, send the actual time it took, not the time it was supposed to take. That number is the baseline you will be measured against, and it lets us judge whether the job needs a larger tank, a faster heat-up, a second lance, or a longer-duty-cycle machine that can run continuously rather than needing a cooling pause.

For a multi-shift plant, say explicitly whether one operator will run the machine across shifts or whether several operators will use it, and whether you expect shared use across workshops. Both affect the control layout, the durability class, and the accessory set.

7. Site constraints and safety requirements

State the constraints that will be checked by a safety or audit visit rather than by a cleaning engineer: whether cleaning takes place inside a production area with other equipment running nearby, whether hot surfaces or electrical cabinets sit within the work envelope, whether the floor is enclosed with no drainage, and whether your site requires a documented hot-work or wet-work permit.

For enclosed or occupied areas, tell us who will be standing nearby. High-temperature steam and hot condensate need operator distance and protective equipment, and where people other than the operator are present, we adjust the configuration: insulated lance, trigger lance with a safety lock, narrower nozzle, and lower-moisture steam. On the HW02 platform the published specifications run to a 6 kW heating element, steam temperature around 160 °C and vapor pressure around 0.8 MPa, with an 80 L SUS304 tank, dry and wet steam modes and an integrated vacuum function; the protection package described on the product page covers leakage, short-circuit, high-temperature, high-voltage, water-shortage and high-voltage-explosion conditions. We reference those figures so you can compare them against your own electrical and safety limits, not as a promise that they are the right ones for your line.

8. Chemicals, detergents and what your site permits

Tell us whether detergents are allowed at all. Many workshops want steam-only cleaning because it removes the chemical handling, the rinse step and the discharge problem, and for oil removal high-temperature steam is often enough on its own. If your plant does require a detergent, send the product name and its data sheet, or tell us the constraint that drives the choice: a food-contact area, a requirement for a biodegradable product, a ban on alkaline cleaners near aluminium, or a customer-imposed chemical list.

If aluminium, brass, zinc-plated parts or painted panels are in the wash zone, say so next to the chemical question. Alkaline products attack aluminium and certain coatings, and this is one of the few places where a wrong pairing causes visible damage rather than a poor result.

If you are cleaning for a regulated environment — food, beverage, pharmaceutical, or a medical area — send the standard you work to. It governs rinse requirements, tank material, and whether the equipment itself has to be cleanable. Our cleaning equipment series lists variants for food, brewery, livestock and medical use, and we size those differently from a general machine-shop unit.

9. Ownership, scale and after-sales expectations

Finally, the commercial and service items that change the specification as much as the technical ones:

  • Number of units and whether you are piloting one machine first. A pilot should be specified so it can later cover the wider plant.
  • Who maintains it. If your own maintenance team services the machine, send their skill set so we can quote replaceable pumps, heaters and seals as spares and tell you what wear parts to stock.
  • Training expectation and language of documentation, including whether operators need a printed work instruction at the machine.
  • Lead time, delivery terms, and destination port or site. If you are buying as an OEM and will resell under your own brand, say so at the start; that is a different build and a different quotation.
  • Budget band, if you can share it. It lets us propose the closest workable configuration instead of the most expensive one.

As a Shenzhen-based manufacturer of cleaning and automation equipment, Shenzhen PowerDe Automation Precision Equipment also develops customized configurations, so a quotation may include changes to tank volume, heating power, voltage, nozzle set and accessory layout. Those changes need the same nine inputs before they can be priced.

A short way to collect all of it

You do not need a formal document. One walk down the line with a phone and a notebook covers items 1 to 4, and five minutes at the electrical panel covers item 5. Send:

  • One wide photograph of the machine and one close photograph of the worst soiled area, with a coin or a hand in frame for scale.
  • The footprint dimensions and the list of surfaces to clean and surfaces to avoid.
  • The contaminant by name, fresh or baked on, and any product data sheet.
  • The result you need afterwards, in your process language.
  • Voltage, phase, breaker rating, water availability, drainage route.
  • Machine count, cleaning frequency, time window, and the actual time a previous clean took.
  • Chemical policy and any regulated-environment standard.
  • Quantity, who maintains it, delivery destination, and whether you need your own branding.

With those, our engineers can narrow the choice — fixed, hand-pushed or self-propelled, steam-only or steam with detergent, tank volume and heating power — and reply with a machine, the reason for that selection, and the accessory list. Without them, the quotation is a guess, and the machine you receive will be matched to somebody else's production line.
