Features and benefits
 HDS 7/12-4 M: Efficiency
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 stainless steel heating coil offers lasting protection against corrosion and prevents the formation of black water.
 HDS 7/12-4 M: Operational safety
Operational safety
The large, integrated water fine filter provides reliable protection against small dirt particles for the high-pressure pump. The built-in exhaust gas thermostat deactivates the drive motor when the emission temperature exceeds 300°C. The Soft Damping System (SDS) compensates for vibrations and pressure peaks in the high-pressure system.
 HDS 7/12-4 M: Storage
Storage
Storage hooks for power cord and high-pressure hose.
Mobility concept
  • Jogger principle with large rubber tyre wheels and steering roller.
  • Integrated tilting aid for effortlessly negotiating obstacles.
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.
