Large-scale catering kitchens are hard places to buy cleaning equipment for. A school, hospital, or corporate canteen that produces hundreds or thousands of meals a day accumulates a specific kind of soil — grease baked onto hot surfaces, starch and sugar residues from sauces, food debris tracked into floors and drains — and it has very little time to clean between services. When a buyer sends a supplier a request that simply says “quote a steam cleaner for our kitchen,” the supplier has no choice but to guess. The proposal that comes back is then often wrong for the site: wrong power supply, wrong tank size, wrong accessories.
The information below is what an experienced supplier needs before quoting central kitchen cleaning equipment — and, just as importantly, what the supplier does with each piece of information. Knowing the second half helps a buyer decide what is worth documenting and what can safely be left for the trial stage.
1. The operating schedule and the real cleaning windows
Ask the kitchen team when cleaning actually happens, not when it should happen. The supplier needs the meal service times, the number of shifts, and the time blocks that are genuinely available: the gap between lunch and dinner service, the period after the last tray has gone out, or a night-shift window. It also helps to say who does the cleaning — a dedicated night crew, or cooks cleaning their own stations at shift change.
With this, the supplier sizes the machine to the window. A kitchen with one hour after service needs a machine that heats and works within that hour, and a tank that does not run dry halfway through. A fixed installation with a tap-water inlet, such as the PowerDe HW02 with its 80 L SUS304 tank, suits a kitchen with a permanent water connection at the cleaning point; a kitchen that cleans different zones at different times may need a mobile unit instead. If the schedule is not stated, the supplier quotes for continuous operation that never happens.
2. The exact cleaning scope, zone by zone
“The whole kitchen” is not a scope anyone can price. Send a list of surfaces: hood exteriors and the filter sections that are reachable without scaffolding or rope access, stovetops and griddles, kettle and oven exteriors, trolleys and insulated transport boxes, floors, floor drains, and the walls beside the cooking line. Then state what is explicitly out of scope — the inside of the exhaust duct, the drain lines, the high hood interiors.
The supplier uses this list to choose nozzles, extension wands, brushes, and other accessories, and to be honest about whether commercial kitchen steam cleaning is the right method for each zone. A surface-cleaning machine handles the first list; it does not clean duct interiors, and a quotation that promises otherwise is worth questioning.
3. What the soil actually is, not just “grease”
Grease is not one problem. Animal fats behave differently from vegetable oils; fresh splatter from that day’s service behaves differently from a baked-on layer built up over weeks of frying; sauces and desserts add starch and sugar that set differently under heat. Describe how long the soil has been in place, where the worst areas are, and what the current method — detergent, scraper, hot water — fails to remove.
This tells the supplier which mode and parameters to propose. Machines that switch between dry and wet steam, like the HW02, let the operator match the method to the soil; the datasheet for that model lists a steam temperature of 160°C and a vapor pressure of 0.8 MPa, which is the range where baked-on grease softens enough to wipe away rather than scrub away. Fresh splatter needs far less energy. Without the soil description, the supplier can only quote a generic configuration and hope.
One caution belongs in every kitchen quotation at this stage: the HW02 product page describes vehicle cleaning applications, not kitchens. A buyer using these figures for a kitchen project should confirm the intended use with the manufacturer before ordering.
4. Utilities and installation conditions at the cleaning point
This is where most failed quotations start. The supplier needs to know what is available where the machine will actually be used: the supply voltage and socket type at that point (the HW02 datasheet lists 220 V and 6 kW heating power), whether a tap-water connection is within hose reach, where the water will drain to, the door widths and floor space needed to move and park the machine, and whether indoor steam use has ventilation.
With these facts, the supplier can quote the correct electrical configuration, decide together with the buyer between a fixed and a mobile machine, and list any site preparation the buyer must complete before delivery. Without them, the quotation has to be redone after a site visit — or worse, the machine arrives and cannot be connected.
5. Safety, hygiene, and audit requirements
Catering kitchens are audited — by HACCP schemes, by the client brands they serve, by local inspectors. Say which audits the kitchen faces and what documentation the auditors ask for: cleaning records, training records, equipment declarations. State whether detergents are restricted in food preparation zones, and note any safety concerns such as shared corridors or wet-floor risks.
The supplier then builds the answer into the proposal: the protection functions listed on PowerDe machines (leakage, short-circuit, high-temperature, high-voltage, and water-shortage protection), operator training, and record templates. Low-water steam cleaning can support a reduced-detergent approach in food zones, but the supplier can only position it that way if the buyer states the hygiene rules first.
6. Trial and acceptance conditions
Finally, tell the supplier whether a trial is possible and on what terms: which equipment the kitchen can offer for a test, who will operate it, and what a pass looks like — a visual standard under raking light, a time standard for a defined zone, or a clean audit result. Suppliers who can test on your own equipment before a full order will usually propose one; suppliers who cannot are quoting on paper alone.
How to send the information
The format matters less than completeness, but a structured request gets a structured answer:
- Photos of each zone: one wide shot and one close-up of the worst soil.
- A simple floor plan or sketch marking the cleaning points, water access, and drainage.
- A one-page sheet covering the six items above: schedule, scope, soil, utilities, audit requirements, trial conditions.
- A photo of the electrical panel at the cleaning point.
The gaps that break a quotation
- A request that says only “send us a price.” The supplier quotes a default configuration, and the errors surface at delivery.
- A scope written as “the whole kitchen,” which no one can price honestly.
- Assumed utilities — 220 V assumed available, a floor drain assumed nearby.
- No cleaning window stated, so the machine is sized for a working pattern the kitchen will never give it.
A supplier who receives the schedule, the scope, the soil description, the utilities, the audit requirements, and the trial conditions can quote a specific, defensible configuration — and where a standard machine does not fit a kitchen’s layout or workflow, that is also the point at which customized steam cleaning equipment becomes a realistic option rather than a sales phrase. Buyers who send these six items get comparable, specific proposals instead of brochures, and comparing suppliers becomes a comparison of engineering answers rather than of adjectives. For a specific kitchen, the contact page is where that conversation starts.
