DYNAJET
220mdh HELI
The DYNAJET 220mdh HELI is a compact hot- and cold-water high-pressure water jetting system designed for flexible installation in a wide range of professional applications. Delivering up to 220 bar and 26 l/min, it combines high cleaning productivity, DYNAJET's HELI valve technology and reliable operation where flexibility, durability and independent operation are essential.
Working pressure should match the task. Surface preparation and general maintenance typically use 150 to 500 bar, while industrial coating removal and concrete work require higher pressure.

Compact cleaning power for mobile professional use
The DYNAJET 220mdh HELI is designed for professional users who need a compact hot- and cold-water high-pressure water jetting system that can be installed as a permanent unit or integrated into customised mobile solutions. Its compact footprint makes it easy to combine with water tanks, hose reels and other equipment, while also making it well suited to fixed installations where space is limited.
Delivering up to 220 bar and 26 l/min, the 220mdh HELI is particularly well suited to applications where high water volume provides efficient cleaning performance. The combination of hot- and cold-water capability, a proven industrial diesel engine and durable industrial components ensures dependable day-to-day operation in demanding professional environments.
Equipped with DYNAJET's HELI valve technology, the machine provides stable pressure characteristics while reducing pressure in the high-pressure hose and spray gun when the trigger is released. Adjustable working pressure and suction pressure control further support reliable operation across a wide range of professional applications.
Whether installed in a service vehicle, enclosed trailer or as part of a fixed installation, the DYNAJET 220mdh HELI provides a durable and flexible water jetting solution for demanding professional use.
Also available without the HELI technology as the DYNAJET 220mdh.
FLEXIBLE MDH MODULE DESIGN
The compact 220mdh HELI can be mounted on a pallet, fitted with wheels, or installed in a van or trailer. This modular setup supports both mobile service work and stationary applications with one system.
HELI VALVE TECHNOLOGY
