Why a fixed unit rather than a portable one
A fixed machine is installed at a known point in the kitchen, connected to the water supply and to a suitable power circuit. That suits sites where the same cooking line is cleaned every day, because the operator is not dragging a machine, hoses and cables across a serving floor. PowerDe’s Fixed Steam Cleaning Machine PowerDe HW02 is described on its product page as a high-temperature, high-pressure machine that switches between dry and wet steam, with dry and wet steam modes plus a vacuum function. For a school kitchen, the practical benefit is repeatability: the same connection points, the same hose routes, the same end-of-day process.
Reading the published specifications against your kitchen
The HW02 page lists a 220 V working voltage, 6 kW heating power, a steam temperature of 160°C, a vapour pressure of 0.8 MPa and an 80 L SUS304 tank, with overall dimensions of 1,200 × 800 × 1,200 mm including handles and a tap-water inlet using a 4-point internal-tooth joint (1/2 inch). Before comparing quotations, a catering manager can check four things against those figures: whether a 220 V supply and an appropriate circuit exist in the kitchen; whether a mains water point with the correct fitting is available near the cooking line; whether the unit’s footprint fits a plant cupboard or a wall position without blocking escape routes; and whether the 80 L tank covers the clean-down area between refills.
Matching the steam mode to the surface
Dry steam and wet steam are not interchangeable. Drier steam is useful where moisture needs to be limited, such as around electrical housings, panel fronts and the upper parts of an extraction hood; wetter steam carries more heat into stubborn grease on griddle surrounds, splashbacks and floor tiles. The HW02 product page also lists leakage, short-circuit, high-temperature, high-voltage and water-shortage protection among its safety functions, with some records of the range adding a further high-voltage explosion protection; the exact list should be taken from the datasheet of the unit being quoted rather than assumed.
What must be confirmed before the machine arrives
School kitchens rarely match a standard specification exactly. Ask the supplier to confirm, in writing, installation requirements (power circuit, water inlet, drainage), training for site staff, the accessory set supplied with the machine, and response times for faults during term time. Ask too about the surfaces in your own kitchen: some flooring and some equipment finishes have manufacturer limits on heat and water volume. A supplier who will review your floor type, appliance list and service hours before quoting is doing the necessary work; one who will not is leaving the risk with the school.
Making the comparison practical
Set out the questions each bidder must answer: how the fixed unit is connected, where it sits, what its published temperature, pressure and tank capacity are, which modes it offers, which safety functions are fitted, and what support looks like during term time. Then request a demonstration on your own cooking line, using your own appliances and flooring, so the clean-down time and the result can be judged on the site rather than in a showroom.
