Water Mist Trolley (High Pressure) 150 & 200 Litre
Supremex manufactures the 150 litre and 200 litre water mist trolleys as mobile, stand-alone firefighting units for rapid industrial and emergency response. A petrol engine drives a high-pressure pump, so the unit works without mains power or fixed piping and can be wheeled to the fire.
Both sizes suit industrial sites, warehouses and workshops, where fast, mobile suppression with minimal water damage matters. The tank is stainless steel and a hose reel lets the operator work from a distance. See the full water mist system range for other sizes.

150 Litre or 200 Litre: Which Trolley Do You Need?
The 200 litre trolley is the larger unit, with a 220 litre tank, a 30 m hose reel and about 5 minutes of continuous discharge at its rated flow. The 150 litre trolley is the smaller, lighter choice for tighter aisles and shorter runs. Contact us for the 150 litre specification sheet and a recommendation for your site.
How the Water Mist Trolley Works
The petrol engine turns a high-pressure pump that draws from the on-board tank and sends the water through the auto-rewind hose to a stainless steel gun. At the nozzle the water breaks into very fine droplets of 150 to 200 microns, which cool the fire and keep water damage low.
On the 200 litre model, the rated flow of 40 litres per minute gives roughly 5 minutes of continuous discharge from the 200 litres of water. The digital level indicator shows the water and foam remaining, so the operator can plan a refill before the tank runs dry.
Where to Use It
- Industrial sites: plants and yards where a fire needs a quick first response.
- Warehouses: stored goods where water damage needs to stay low.
- Workshops: machinery areas where a mobile unit can be rolled to the fire without laying hose from a hydrant.

What to Confirm Before You Order
- Size: a bigger tank runs longer before a refill, and a smaller trolley is lighter and easier to move through tight spaces. Tell us the area and the longest fire you need to fight.
- Hose length: tell us the distance from where the trolley will be parked to the farthest equipment.
- Doorways and aisles: check that the route to the hazard is wider than the trolley frame. The 200 litre frame is 760 mm wide and 1240 mm long.
- Foam use: the 200 litre tank has 20 litres of foam capacity alongside the water. Tell us if foam is part of your requirement.
- Fuel and refilling: the engine runs on petrol, so plan where fuel and refill water will be kept.
- Where it will run: the petrol engine gives off exhaust fumes, so use the trolley in the open or in a well-ventilated area, not in a closed room.
Water Mist Trolley FAQs
What is a water mist trolley used for?
It is a mobile, self-contained firefighting unit for industrial sites, warehouses and workshops. A petrol engine drives a high-pressure pump, so it needs no mains power or fixed piping. The operator pulls the hose reel to the fire and fights it with a fine water mist that limits water damage.
Which is better, the 150 litre or the 200 litre trolley?
Neither is better for every site. The 200 litre trolley carries more water and a 30 m hose reel, so it runs longer between refills and covers larger areas. The 150 litre trolley is the smaller choice for tighter spaces and shorter runs. Share your site layout and we will recommend one.
How long does the tank last?
On the 200 litre trolley, the rated flow of 40 litres per minute gives about 5 minutes of continuous discharge. A digital level indicator shows the water and foam left, so the operator knows when to refill. Ask us for the run time of the 150 litre model.
Does the trolley need electricity or a hydrant connection?
No. It carries its own stainless steel tank and a petrol engine that drives the pump, so it works where there is no power supply or hydrant point. Fill the tank with water and keep the fuel tank topped up before use.
Can I use it indoors?
Use it in the open or in a well-ventilated area, because the petrol engine gives off exhaust fumes. For closed rooms, a fixed water mist system or an extinguisher is the better choice.
How is it different from the 50 litre trolley mounted water mist unit?
The 50 litre unit is a compressed-air trolley extinguisher with a 5 m hose. The 150 and 200 litre trolleys use a petrol-engine-driven pump and an auto-rewind hose reel, and carry much more water, so they suit larger areas.
What is the price of a water mist trolley?
Price depends on the size, configuration, quantity and delivery location, so we quote after confirming your requirement. Send your site type and hose length needs by WhatsApp or the quote form, and the Supremex team will reply with pricing and delivery details.
