Try it out without obligation: Get your free Ecowaterjet test kit

With Rabmer's free test kit, you can measure the current hot water consumption in your showers and faucets and quickly and easily check how you can reduce it by up to 50% with the innovative water and energy saving inserts for showers as well as our 5l/min aerators for sinks without any loss of comfort for your guests.

Reducing water and energy consumption
The current energy price increases pose challenges for all of us. Now, in the heating-free period, it is above all the hot water which requires a high energy input and causes the running operating costs to rise steeply. The greatest savings potential here lies in the consumption in the showers and hand wash basins - thanks to our system, this can be reduced by up to 50% without sacrificing shower comfort. Conventional economy shower heads reach their limits at a flow rate of 9 l/min, anything below this is at the expense of water pressure and showering enjoyment for your guests. Our solution, on the other hand, manages to reduce the flow down to 6 l/min without causing any guest complaints.

How our Ecowaterjet for the shower works
This is made possible by the ingenious use of the Venturi principle, which is also used by Kärcher high pressure cleaners. By narrowing the diameter in the form of a funnel, the water is greatly reduced on the one hand, but also greatly accelerated. This creates a vacuum, which causes air to be sucked in via a bypass and mixed with the water. The volume of the strongly accelerated and swirled, air-enriched water is thus increased and the water pressure thus remains unchanged at a high level.

Quickly determine your savings potentialwith the Rabmer test kit.

greentech@rabmer.at, consisting of a measuring bag to determine the flow rate, 2 mini-turbine savings fittings (type WR5 with 50% savings and WR4 with 40%) and a flow limiter for washbasin fittings with 5 l/min. Measure the savings and enter the results in our online savings calculator. This way you can see in no time how much money, energy and water you can save quickly and easily. By the way, the purchase costs for the saving faucets pay off in a few months - here is an example: a 100 room business hotel saves about € 16.000 per year with investment costs of only € 4.450,- by using the mini turbine for the shower as well as the aerators for the wash basins. That really pays off!

Simply send an email to greentech@rabmer.at with the password "test kit" and please include the hotel name, delivery address, number of rooms and contact details - within a few working days you will receive the test kit free of charge.
