Industrial steam cleaners are the highest level in portable steam cleaners. The increased power these industrial steam cleaners offer, means a higher volume of steam released at a greater force.
The KHD industrial steam generators range from 9kW to 36kW. As the kilowattage increases, so does the amount of steam produced, this results in the steam being released at a greater rate and at force.
Contact KHD to find out what industrial steam generator would be required for your application.
KHD Technology are world-leading experts in conveyor belt cleaning using steam technology. We have manufactured the widest range of conveyor belt steam cleaners available anywhere, which vary depending upon which conveyor belt you are cleaning:
Modular Mesh Conveyor Belts (plastic and metal) – The complex belt structure makes modular and mesh conveyor belts notoriously hard to clean. However, the patented KHD Jet System 4 with patented Spinner is specifically designed to clean these conveyor belt systems.
The Jet 4 system is portable and fully adjustable to fit virtually any conveyor width, and sitting securelyclips onto the edge of the conveyor frame, it’s programmed to cover the width of the conveyor belt releasing a dry steam vapour, through carefully engineered jets to create the optimum cleaning power. The intense combination of pressure and heat removes the debris and germs from the belt.
Flat Conveyor Belts (polymer belts including PU and monolithic) – For flat polymer belts we have a range of steam cleaning equipment available, the models include portable systems with or without brushes and patented single or dual head fixed systems. Contact us today to discuss which system is suitable for your application.
The steam cleaning systems for polymer conveyor belts, sit over the entire width of a belt and releases steam over the full surface and edges as the conveyor belt passes through. A version with a food-grade brush is also available to remove stubborn debris.
Special conveyor belts – For conveyor belts that are unconventional or in hard to reach areas we offer a range of cleaning systems, from a hand held steam cleaner to fully customised systems. Get in touch to find out more.
Dry steam is generated by boiling water inside a closed vessel to a preset pressure, which will reach a higher temperature while under pressure, and when the pressurised steam is released into normal atmosphere it instantly expands, like a continuous explosion (the hiss) and almost instantly cools to 100˚C at the point of release creating a low moisture vapour that KHD harnesses in different ways for cleaning tasks.
Dry steam cleaning is ideal for cleaning food factories and dry environments, as there is no waiting time for the conveyor belts to dry.
When using dry steam there is no requirement for detergents or cleaning agents, this is because the combined heat and force of the dry steam removes mould and bacteria and breaks down debris and allergens.
Yes, dry steam breaks down stubborn grease quickly and easily. Steam cleaning is said to be the best way to clean greasy surfaces, as it negates the need to scrub or use strong chemicals to loosen the dirt.
No, the powerful steam vapour loosens the dirt and the high temperature kills mould and other harmful bacteria and breaks down debris and allergens.
‘Dry steam’ has been heat treated, so it does not contain any liquid water molecules. All the water molecules are in a gaseous state, i.e. water vapour.
In reality, most people would still refer to steam with a 5%-10% moisture content as ‘dry steam’. Also, remember that dry steam has the potential to become wet, if it hits a cool material, it will condense to a liquid state.
Whether you need ‘dry steam’ depends on your cleaning application. You might not always need dry steam, even though it is heavily marketed as the go-to option. We create the right kind of steam for the cleaning you require. Our continuous steam generators provide constant steam output which can be adjusted by pressure and dryness.
Dry steam is often a good choice for removing oils, allergens, killing bacteria, and mold. Wet steam may be a good option for moving larger pieces of debris off conveyor belts.
Contact us today to discuss your steam cleaning application in more detail. The good news is, whatever type of steam you require, our steam generators are capable of creating a range of dryness fractions. That means you have the opportunity to trial different steam variants, all from the same machine.
Dry steam offers:
Less water – minimal residue
Faster drying – reduced downtime
More heat transfer – ideal for killing mould and bacteria
Our system can deliver dry or wet steam, depending on the application.
Yes. We can supply spare parts for basic maintenance and replacements. For more complex repairs, the machine will need to be serviced either at KHD in the UK or by one of our trained distributors worldwide.
Whenever a machine comes in for repair, we also carry out a full service, which resets the annual service clock.
First, contact KHD or the distributor you purchased the machine from.
Where possible, we’ll troubleshoot the issue over the phone with your on-site engineers and can send out replacement parts for simple fixes.
For more complex repairs, the machine will need to be returned. In the UK, we can arrange next-day pallet collection, begin work as soon as it arrives, and typically return it the day after it’s been repaired and serviced. We aim to have it back with you within 5 working days of pickup, and we’ll work with you to arrange convenient pickup and drop-off times.
The dryness fraction measures how much of the steam is in the vapour (gas) phase compared to the liquid (water droplets) phase. A dryness fraction of 1.0 means the steam is completely dry. Lower values indicate increasing moisture content.
When steam is released into the atmosphere, it rapidly cools and naturally becomes wetter as it mixes with air and begins to condense. That’s why our manifolds are designed to deliver steam to the conveyor belt surface as quickly as possible, while it’s still in its high-dryness phase — maximising cleaning efficiency and heat transfer.
No, it won’t. Although the steam is generated at 180°C inside the machine, it rapidly cools to around 100°C when released into open air. This higher generation temperature creates dry steam with greater cleaning power and volume, but the actual contact time with the belt is extremely short—just a brief flash of heat lasting less than a second.
This flash heating does not harm the belt, even those rated below 100°C, because the heat doesn’t penetrate deeply or linger long enough to cause distortion.
In fact, the cleaning process can extend belt life:
Yes. UK pressure equipment regulations require steam generators to undergo at least an annual service; some companies prefer more frequent services to keep their equipment in the best working order. We pride ourselves on how quickly we carry out servicing, meaning you get your machinery back at your facilities with minimal downtime.

Superheated steam is steam that has been heated beyond the boiling point for its pressure. At atmospheric pressure (1 bar), water boils at 100°C — so any steam above that temperature at this pressure is considered superheated. It contains no water droplets and carries more energy, making it highly effective for cleaning.
In our machine, steam is generated at 180°C under pressure, which is saturated steam at that point. However, as soon as it’s released into the open air, the pressure drops instantly to atmospheric. Since the steam is still at 180°C but now at 1 bar, it becomes briefly superheated.
This superheated state only lasts for a few milliseconds in open air, as the steam rapidly expands, mixes with ambient air, and cools. To make use of this short-lived high-energy phase, our nozzles are engineered to deliver the steam at nearly Mach 1 velocity, allowing it to reach the conveyor belt before it cools to saturated steam.
