HDS 13/20 -4S

The HDS 13/20-4 S is the most powerful hot water blaster in the Super class and is fitted with a 4-pole, water-cooled electric motor and large LED display.

You will not find more power in the Super class of hot water blaster cleaners from Kärcher: the HDS 13/20-4 S is the most powerful machine that we offer. The high water flow rate allows two-spray lance operation, making time-consuming tasks easier and quicker. The EASY!Force HD trigger gun uses the recoil force of the high-pressure jet, thereby reducing the holding force for the operator to zero. With a range of innovative equipment features, like the eco!efficiency mode, service switch for water hardness regulation, turbo blower, precise cleaning agent dosing unit, optimised burner engineering, high pump efficiency and patented nozzle technology, not only is the machine highly efficient, but it also delivers outstanding cleaning results. Another highlight is the large LED display on which the filling levels of fuel and cleaning agent, as well as information on system care, can bechecked easily at any time. The ease of use of the machine, sophisticated mobility concept and easy access to all of the relevant components also make handling, transport and servicing much easier for the operator.

Features and benefits
High efficiency
  • In eco!efficiency mode, the machine operates at the most efficienttemperature range (60 °C) – even at the maximum water flow.
  • The burner cycles are optimised to reduce fuel consumption by 20 percent compared to full load operation.
  • The Soft Damping System (SDS) compensates for vibrations and pressure peaks in the high-pressure system.
  • Large, easily accessible water fine filter for protecting the pump against dirt particles in water.
  • Access to machine operation information on duration of use andnecessary service intervals.
Maximum efficiency
  • Highly efficient, tried-and-tested burner technology.
  • 4-pole electric motor with three-piston axial pump.
  • Water-cooled motor for a high level of performance and durability.
  • Spacious storage compartment for cleaning agents, gloves or tools, for example.
  • Easily accessible for left/right-handed people and perfect for two-lance operation.
Detergent dosing
  • Accurate dosing valve ensures a low consumption rate.
  • Easily switched between detergent tanks 1 and 2.
  • In position 0, rinsing is carried out automatically.
Save energy and time: EASY!Force high-pressure guns and EASY!Lock quick-release locks.
  • At last – work without getting tired: the EASY!Force high-pressure gun.
  • EASY!Lock quick-release locks: durable and robust. And five times faster than screws.
