The Nilfisk MH3, MH4 and MH5 were the first Hot-Water range to implement an EcoPower boiler system that offers higher efficiency, reduced emissions and fuel costs. The MH 5 hot pressure washers can display pump hours, low fuel and Flame Failure errors.
The Ehrle HD is available as a standard or premium machine. Both have the same pumps. The only difference is the premium comes with a robust 20 Meter Hose reel and turbo lance. The Etronic PCB controls the entire machine and is in every Ehrle Hot Pressure Washer. Etronic 2 has a flame failure cut out and low-level indicators. Best of all, it's German Built.
Keep things a little more straightforward with DTE & Dirt Driver. Both machines use brass head positive displacement pumps sending cold water to a Lavor Boiler. Flow Sensitive unloaders are standard, as too are timed shutdown functions.
