Hot Water Without Emissions: The Solution for Indoor Environments

In enclosed professional environments, being able to use hot water without producing combustion fumes is a significant advantage.

The KF-E’s electric boiler heats the water without generating combustion fumes, making the machine particularly suitable for industrial environments, especially the food industry, workshops, production facilities and other indoor spaces where maintaining air quality is essential.

The combination of high pressure and hot water helps remove stubborn dirt, grease residues and the types of contamination commonly found in professional environments.

KF-E also operates with significantly reduced noise. It is three times quieter than a pressure washer with a diesel-fired boiler, improving operator comfort even during extended use.

Why Choose an Electric Hot-Water Pressure Washer?

In the food and wine industries, cleaning operations require high performance as well as particular attention to the working environment. In wineries, wine-production facilities and food-processing plants, being able to use hot water without combustion fumes and with reduced noise offers a practical advantage.

KF-E allows you to:

• work in enclosed environments without producing combustion fumes;
• use water heated up to 85°C, helping remove stubborn dirt and grease residues;
• operate with reduced noise compared with a pressure washer with a diesel-fired boiler;
• move easily around the workplace thanks to its professional configuration;
• handle a wide range of cleaning requirements, both indoors and outdoors.

Designed for Professional Environments

KF-E has been developed around the practical needs of operators working in professional environments every day.

The machine combines a design that facilitates handling, professional components and dedicated systems for hot-water management, providing a versatile solution for a wide range of cleaning applications.

Professional Mobility and Handling

The two 300 mm rear non-marking wheels and two swivel front wheels with brakes make the machine easier to move and manoeuvre, even in tighter workspaces.

The structure also features front and rear protective bumpers, designed to protect the machine during handling.

Another distinctive feature is the central single anchoring point, which allows the machine to be lifted using a crane or winch — a useful solution in professional environments where the machine needs to be moved or positioned in hard-to-reach areas.

The non-marking rubber delivery hose completes the configuration, helping protect surfaces during cleaning operations.

Professional Control Panel

KF-E features a professional control panel with a new electronic system, designed to provide precise control over the machine’s main functions.

The system includes an electrical power LED, low-voltage alarm, amperometric control with overcurrent alarm, micro-leak detection system and routine maintenance alarm, making it easier to monitor the machine’s operating status.

Comet LW Pump: At the Heart of Performance

The pump is one of the key components in ensuring performance, reliability and consistent operation in a professional pressure washer.

KF-E uses a professional Comet LW pump with three axial pistons, a brass pump head and hot-water seals.

This configuration is designed to provide durability and consistent performance even in demanding professional applications.

Electronic Temperature Control

KF-E’s new electronic system features a high-precision temperature regulation system, designed to keep the selected temperature stable during operation.

The boiler is also activated by a pressure switch, contributing to efficient management of the heating system.

Where to Use KF-E

Thanks to its combination of hot water, electric power, reduced noise and zero combustion fumes, KF-E is suitable for a wide range of professional environments.

Key applications include:

• Food industry
• Industrial sector
• Construction
• Agriculture
• Vehicle washing

The ability to operate in enclosed environments represents a key added value of Full Electric technology, expanding the machine’s possible applications while maintaining its versatility for professional outdoor use.

KF-E in the Food Industry

In the food industry, professional cleaning requires particular attention to hygiene, surfaces and the effective removal of residues.

The ability to use hot water without generating combustion fumes, combined with reduced noise and a configuration designed for professional handling, makes KF-E particularly suitable for food-processing and production environments.

Hot water also helps remove dirt and grease residues, supporting everyday cleaning operations.
