Our medium and super class hot water pressure washers boast impressive features. They are environmentally friendly and efficient thanks to the Eco mode, a service switch for adjustment of water hardness, turbo fan, precise detergent dosage, optimized burner technology and high pump efficiency. Accessories are optimized for specific applications to suit customer needs. A central, clearly arranged control panel designed for intuitive operation, spray lance holder, and LED displays make this a user-friendly unit. Large rubber-tired wheels, swivel casters, ergonomic push handles, forklift lifting points, lashing rings and a tilting aid provide mobility and easy transport. Flue gas monitoring, a corrosion-proof chassis, machine protector system, and three-piston axial pump with ceramic pistons and heat-resistant flue outlet guarantee safety and reliability, and easy access to components makes this unit service friendly. A service switch can even call up operating data for troubleshooting.
HDS MID CLASS
Economical
temperature range (60°C) with full water flow. Burner cycles are optimised to reduce fuel consumption by up to 20% compared to full-load operation.
Operational reliability
The large, integrated fine-mesh water filter reliably protects the high-pressure pump against dirt particles. An integrated exhaust gas thermostat switches off the drive motor if the exhaust gas temperature exceeds 300°C. The soft damping system (SDS) compensates for vibrations and pressure surges in the high-pressure system.
Storage
Storage hooks for power cord and high-pressure hose.
Mobility concept
- “Jogger” design with large wheels and castors.
- Integrated tilting aid for effortlessly negotiating obstacles such as steps and kerbs.
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.
