Most enquiries for industrial steam cleaning equipment describe the machine the buyer thinks they want instead of the job they need done. The supplier then quotes to the words in the brief, the machine arrives, and the gap between the two appears as a failed commissioning. The list below is what a brief should contain so that a supplier can refuse the wrong job before the order rather than after it.
What is being cleaned, and what is on it
State the equipment or component, its material, and its surface condition — painted, plated, machined, coated, bare. Then describe the soil by what produces it: which process leaves the deposit, at what temperature, and how long it has been accumulating. Photographs of actual fouling, taken at the machine and not at a demonstration, are worth more than any adjectives in the brief. If you cannot describe the soil, say so and ask the supplier to identify it from a sample or a visit.
Then state what must not be affected: seals, bearings, electrical enclosures, sensors, insulation, coatings, calibration. A brief without that list invites damage.
The site constraints, not the wish list
- Power: available supply and voltage at the point where cleaning happens, and the cable route. Fixed units in this duty class draw substantial heating power — the 6 kW, 220 V machine in PowerDe's range is an example of a specification that determines the circuit and not just the plug.
- Water: availability, pressure, quality, hardness, and the inlet fitting. The customer's fixed units are listed with a 4-point internal-tooth tap-water connection, which has to be matched to site pipework rather than assumed.
- Drainage and residue: where effluent and collected grease go, what the site's discharge rules allow, and whether an interceptor exists.
- Reach and access: the distance from the supply point to the farthest part being cleaned, which sets hose and wand length, and the width of aisles and doors the machine has to pass through.
- Time: how long the cleaning window actually is, and how long the equipment must take to dry before production restarts.
The numbers you want returned, stated in the brief
A brief that asks for a quotation should also ask for the data you will use to compare quotations: steam temperature and pressure at the nozzle, water consumption per hour in each mode, the mode-selection behaviour, the published safety protections by name, and the consumable list with part numbers, prices and lead times. Several pages in PowerDe's cleaning range publish dimensions, heating power and tank volume but not steam temperature, pressure, runtime or water consumption — so the brief should request them explicitly and require that the answer appears in the quotation, not in a conversation.
The application the supplier claims, in the supplier's own words
Ask the supplier to state what their own documentation says the machine is for, and put that sentence in the brief. It is a cheap protection. The Fixed Steam Cleaning Machine PowerDe HW02, for example, is described on its product page around vehicle cleaning at fuelling and parking sites — exterior, interiors and engine compartments — not as general industrial equipment, and the customer's own site shows inconsistent model naming around the 220 V fixed units. Recording the stated application, and asking separately whether it covers your duty, turns an assumption into a documented answer from the manufacturer.
The trial, written as a requirement
End the brief with what has to be demonstrated before any order: a trial on one real item of your equipment, with the passes required, litres used, drying time and hand-labour recorded. That single paragraph changes the character of the enquiry. It moves the supplier from quoting a catalogue entry to committing to a result, and it gives you a comparison you can trust when the second quotation arrives.
