Comet KF Extra - Hot Water Pressure Washer with Anti-Limescale Device
The Comet KF series pressure washers are designed for applications where flow rate, detergent capacity, and robust construction are primary criteria. Designed for large water volumes , long work cycles , and intensive use on large surfaces, they are the ideal solution for professional and industrial applications.
The Comet KF Extra pressure washers are equipped with a large 16 L detergent tank and, unlike the KF Classic version, have an anti-scale device , PED 2014/68/CE cat. II certification and electronic temperature regulation .
Available models
- KF Extra 9.16 16/210 T - max. 210 bar - flow rate 960 L/h
- KF Extra 9.21 21/170 T - max. 170 bar - flow rate 1260 L/h
- KF Extra 10.22 22/210 T - max. 210 bar - flow rate 1320 L/h
- KF Extra 10.17 17/250 T - max. 250 bar - flow rate 1020 L/h
Thanks to the 1400 RPM professional 4-pole motor and the vertical boiler with double spiral stainless steel coil , these models guarantee high reliability and durability even in the most demanding conditions.
Ideal for use in the food industry to clean and remove animal or plant waste, in cleaning stables but also in cleaning construction equipment and similar.
There are many advantages to using the Comet KF Extra, including shorter washing times thanks to the cleaning power of hot water, shorter drying times for the washed parts, deeper cleaning of non-water-soluble dirt , less use of detergent and therefore lower fixed cleaning costs.
Technical Specifications
The Comet KF Extra is powered by a professional 4-pole 1400 rpm motor , with a 19 L diesel tank and a boiler fuel consumption of 6.4 L/h (8 L/h in the 10.22 version), ensuring extended autonomy and reliability during continuous operation. The vertical boiler features a stainless steel body with a double spiral coil, an electronic temperature regulation system with low setpoint oscillation, and integrated thermal protection. The burner is operated by a flow switch with delayed start, while the safety valve and delayed Total Stop system ensure safe operation even during prolonged inactivity.
The Comet KF Extra hot water pressure washers feature adjustable water outlet temperatures between 85 and 140°C , a 16-litre detergent tank , a 10-metre high-pressure hose, and large wheels (ø 300 mm) for stability and easy transport. The inspectable suction filter and anti-limescale device with a 2.5-litre tank complete a technical package designed for durability and optimal maintenance over time.
