Test kit for hotels: Save water & energy when showering without sacrificing comfort - try it out now for free!

With the free test kit from Rabmer, you can measure the current hot water consumption of your showers and taps and quickly and easily check how you can reduce this by up to 50% with the innovative water and energy-saving inserts for showers and our 5 l/min aerators for washbasins without any loss of comfort for your guests.

Reducing water and energy consumption
The current rise in energy prices presents us all with challenges. Now, during the heating-free period, it is mainly hot water that requires a high energy input and causes running operating costs to rise steeply. The greatest savings potential here lies in consumption in showers and hand basins - thanks to our system, this can be reduced by up to 50% without compromising on shower comfort. Conventional economy shower heads reach their limits at a flow rate of 9 l/min; anything less is at the expense of the water pressure and the showering pleasure for your guests. Our solution, on the other hand, manages to reduce the flow rate to 6 l/min without causing any complaints from guests.

How our mini turbine 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, for example. By narrowing the diameter in the form of a funnel, the water is both greatly reduced and 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 water enriched with air is thus increased and the water pressure remains high.

Quickly determine your savings potentialwith the Rabmer test kit
Order your free test kit from us at
greentech@rabmer.at, consisting of a measuring bag to determine the flow rate, 2 mini turbine savings taps (type WR9 with 50% savings and WR10 with 40%) and a flow limiter for washbasin taps with 5 l/min. Measure the savings and enter the results in our online savings calculator. This will show you in no time at all how much money, energy and water you can save quickly and easily. Incidentally, the purchase costs for the energy-saving taps pay for themselves in just a few months - here is an example: a 100-room business hotel saves around € 16,000 a year by using the mini turbine for the shower and the aerators for the washbasins at investment costs of just € 4,450 - that really pays off!

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