A fixed steam cleaning machine is installed at one position and works from it. In a kitchen, that single fact decides everything else: which equipment can be reached, which services have to be run to that position, and which work stays with the methods used before. Fitting one in is therefore a two-way assessment. The machine is measured against the equipment you actually clean, and the room is measured against the machine. The order below starts at the equipment, because a machine chosen first has to be justified afterwards, while a job described first only has to be confirmed.
Write down the equipment you clean, surface by surface
Walk the kitchen and write one line per piece of equipment, naming the surfaces actually cleaned on it, how often they are cleaned, who does it now, and how long it takes. That last column is the one that decides whether anything is worth changing. A line that reads "wiped weekly, four minutes" does not need a new machine, and writing it down protects you from buying one.
Then sort every line into three groups, because the groups need different methods:
- Exterior surfaces cleaned on a schedule. Frames, panels, legs, splashbacks, the outside of a hood, trolleys, stands, and the floor edge around a unit. This is the group a fixed machine works on, and it is the group where central kitchen equipment steam cleaning is specified against a list of items and measured distances rather than against a room.
- Surfaces that open into the machine. Cavities, interiors, filters, ducts, drains, and anything with electronics or insulation behind a panel. This group needs a written answer before anything is attempted, not a technique.
- Surfaces that are moved to be cleaned. Shelves, pans, trays, utensils and small parts. That is a sink and a dishwasher, and no steam machine changes where that work happens.
The first group is where heat and pressure earn their place. Grease baked onto a stainless frame during service behaves differently from grease on a plate, and the difference is temperature, not effort. The same two numbers are also why the second group is a question rather than a task. A panel seam, a gasket, a bearing seal and an adhesive bead are all designed to keep water out, and steam at 160 degrees Celsius and 0.8 MPa reaches them from someone who has been told what each one tolerates. Write the groups before you read a single specification, and keep the excluded lines in the document.
Measure reach from the place the operator will stand
A fixed unit is a point, and every distance in the kitchen is measured from that point. The cabinet of the PowerDe HW02 fixed steam cleaning machine is listed at 1,200 x 800 x 1,200 mm including handles. Tape that rectangle on the floor at the position under consideration, then walk the kitchen from it and answer these questions in writing.
- Which equipment is within the distance the hose and lance reach with the operator facing the surface, not facing the machine? A range hood is cleaned above the head and a stovetop is cleaned at waist height; both are on the same vertical line and neither is at arm's length from the same standing point.
- Does the unit block an aisle, a door, a floor drain, a trolley route or an escape path when it sits where you have put it? A position that works while the kitchen is empty often fails during service, when the same aisle carries food.
- Can every door on the delivery route take 1,200 mm of width plus a person on each side, and does the route avoid the servery and the pass?
- Is there clearance to open the cabinet for the tank, the controls and the connections, and room to stand beside the machine for a full task rather than to lean past it?
The published page gives the cabinet size and the tank, but not the hose and lance lengths, so draw no circle until those two numbers arrive in writing. When a surface turns out to be out of reach there are three honest answers: a second station, a longer lance, or the surface leaves the scope. Each of them is a decision that can be priced and planned. Hoping is not. For commercial cooking equipment degreasing, reach is the first constraint, and it is decided by a tape measure long before anyone discusses steam.
Check the four services at that position
Electricity. The machine is listed at 220 V and 6 kW. That is a dedicated circuit with correct protection, installed by our electrician, not an extension lead shared with a fryer. The protections named on the page, covering leakage, short circuit, high temperature, high pressure, water shortage and high-pressure explosion, protect the machine; they do not replace the protection device in the circuit feeding it. Ask the supplier which risk each one covers and what the installation still has to provide.
Water. The inlet is a half-inch female threaded connection for tap water. Measure the distance from the nearest tap, ask whether the supply can be shut off for filling without closing a work area, and ask whether a filler hose is supplied for that thread or whether an adapter is needed. A filling routine that crosses the kitchen twice a shift is a cost that never appears on a data sheet.
Drainage. The machine empties a steam generator and an 80-litre tank, and that water is greasy. In a kitchen it passes a grease interceptor on its way out. Ask the local authority whether the discharge from a steam cleaner needs anything specific in your area, and choose the drain before the machine arrives rather than after.
Floor, air and clearance. A stainless tank filled with water needs a floor that is level and able to carry it, with the weight of a person working beside it. A machine producing steam at 160 degrees Celsius in an already warm room needs ventilation that has been thought about, not merely present. And the position needs clearance from the fryer's oil, the grill face, stored packaging and anything else that should not be near a hot surface or a source of moisture.
Match the machine's cycle to the window you actually have
The published figures describe the machine. The schedule needs the gaps around it. The tank is 80 litres of SUS304, but the number that matters in a real kitchen is not the tank size: it is how much work one fill supports, and how long a refill and a restart take. Neither figure is published, so ask for both.
Then write down the window. What is the time between the last service and the start of the close-down clean, and who is in it? A fixed machine suits work that happens in batches at known times: the hood front after service, range frames twice a week, the floor edge around the line at the end of the week. It suits a kitchen where the same person runs the same rounds and can be trusted with a written method. It does not suit work that appears at random times across the whole room, because a fixed machine cannot follow it.
Two more scheduling questions belong in the same conversation. The first is preheat: how long the machine takes to reach working state from cold, and whether it may be left ready between jobs or has to be started for each one. The second is method. The machine is listed with dry and wet steam modes and a vacuum supplied with it, and which mode belongs on which surface, and what that vacuum is meant to do at the end of a pass, should sit in the supplier's written method rather than in a decision made late at night by whoever is left on shift.
What a fixed position leaves to other methods
Half of an honest fit assessment is a list of work that continues unchanged. In a kitchen that list is specific:
- Upper ductwork, and anything above the hood line, which belongs to the duct cleaning contractor and their schedule.
- The inside of ovens, fryers, grills and dishwashers. Those cavities have their own chemistry and their own instructions from the maker of the appliance.
- The grease interceptor, floor drains and gullies, which are emptied and flushed on their own cycle.
- The cold room, the store and the prep benches on the far side of the kitchen, if the measured reach does not cross to them.
- A full floor during close-down, and any work that follows the day's mess instead of a timetable.
None of these are objections to the machine. They are the part of the job that stays as it is, and they belong in the same document as the part that changes. A proposal that claims otherwise has not walked the kitchen at the hour the work would actually happen.
Ask for the answers the data sheet does not carry
The published page for a fixed machine gives voltage, power, temperature, pressure, tank volume and material, the water inlet, the steam modes, the cabinet size and the protection list. It also lists vehicle washing among the uses the machine is offered for, which is exactly why a kitchen installation should be confirmed as an intended use rather than inferred from a specification. Six questions have short answers and none of them are on that page:
- Preheat time from cold, and whether the unit may be left ready between jobs.
- Hose and lance lengths, and the working reach with the fittings as supplied.
- How long a full tank produces steam, and how long a refill and recovery take.
- Whether 160 degrees Celsius and 0.8 MPa are measured at the boiler or at the nozzle, and what they are at the nozzle with the hose supplied.
- Recommended distance and angle on stainless, painted and powder-coated surfaces, on gaskets, and on adhesive beads.
- What is required for use in a food preparation area, and which of the listed protections is intended to cover that use.
A supplier who answers those in writing is a supplier whose machine can be planned around. A supplier who answers in adjectives has also told you something, just not about the machine.
Put the fit on one page
The deliverable of this exercise is a short written record, not a decision. It contains the equipment lines in scope and the lines excluded, with the reason for each exclusion; the position on the floor and the measured reach from it; the four services at that position, each with a name and a date against it; the work the machine would take over, and the windows in which it would happen; and the questions asked, with the answers received. That record is what makes the installation reviewable a year later, by someone who was not in the kitchen on the day.
Send the record to the supplier rather than a summary of it. A machine can only be confirmed against a described job, and a summary removes the details that decide the answer. The surfaces in scope, the measured reach, the utility positions and the questions above can all go through the contact page, with a request for the reply in writing.
A fixed machine earns its place in a kitchen in a narrow way. It takes over a defined set of exterior surfaces, at known times, from one position that has been measured. Where that description matches the kitchen, the work becomes regular, and the record above is the reason it stayed regular. Where it does not, the machine becomes furniture with a warranty. The fit is decided on paper and in the room, before the delivery, and both of those are free.
