Description

Nilfisk MH 4M professional three-phase hot water pressure washer

The MH 4M allows for hot water cleaning operations and use for up to 4-6 hours per day. Thanks to its high-efficiency, low-consumption EcoPower boiler, it offers more efficient and faster cleaning. In addition, maintenance can be carried out quickly, as all the main components are easily accessible and inspectable. The fuel level indicator on the tank minimises downtime.

Nilfisk has designed the new hot range with the aim of achieving maximum manoeuvrability on all types of surfaces. Thanks to their innovative design, the MH4 series pressure washers are always easy to push or pull, depending on the application. In addition, the layout of the components has been designed to maximise balance and manoeuvrability in all situations

High-efficiency motor 1450 rpm (50 Hz) or 1750 rpm (60 Hz)
Brass pump head
3 ceramic pistons
Pressure control activation
Oil cup and diesel tank
Oil shortage indicator and safety float

Suitable for a wide range of uses, it is the ideal machine for agricultural environments, for cleaning and maintaining machinery or in any professional environment that requires thorough cleaning. It is easy to transport thanks to the double handle on the back and the four wheels, which allow it to be moved easily and used wherever it is needed.

The machine is also equipped with a Total Stop system, which automatically shuts down the machine when the trigger is released.

It is equipped with a vertical diesel-powered boiler that heats water up to 90°C.

In addition to its extreme practicality and high performance, this hot water pressure washer is lightweight, easy to handle, very convenient to transport and also features a very attractive design. The controls are simple and intuitive

Why use a hot water pressure washer? A hot water pressure washer is necessary when you need to break down oily or particularly stubborn dirt in the shortest possible time. The cleaning efficiency of hot water is significantly higher than that of cold water (up to 50% more on certain types of residues), as heat helps to dissolve dirt, and the effect of heat on the surface facilitates rapid drying. Using a hot water pressure washer therefore means: shorter washing time (for the same amount of dirt), better breakdown of non-water-soluble dirt, shorter drying time and less detergent; in short, lower fixed cleaning costs.

Main Features

High-efficiency EcoPower boiler with an efficiency of over 92%, which reduces fuel consumption. In eco-mode, it is possible to work at 60°C with maximum boiler efficiency: in fact, an increase in temperature above 60°C increases fuel consumption.

The BURNER REGULATION THERMOSTAT: allows you to regulate the water outlet temperature

A knob on the control panel allows you to select the pressure for drawing detergent from the tank (10 l)

Large boiler drain made of stainless steel.

Equipped with the innovative Delayed Total Stop system, which stops the machine when the trigger on the gun is released, allowing for even greater energy savings and maximum power when restarting compared to the traditional Total Stop system.

Low-pressure detergent suction: The chemical product (which does not pass through the pump but is sucked in by a Venturi system) is dispensed by reducing the machine's operating pressure. It is therefore possible to distribute the product with a wide conical jet on surfaces close to the operator.

MOTOR: three-phase electric (400 V) 7.9 hp (5.9 kW)

- Diesel tank (15 l)

- Detergent tank (10 l)
