Designed to last for years

Our operating systems are designed and developed by ourselves to provide you with the optimal user experience.

Self designed operating system

Our operating systems are self-written and specially designed for the control of our cocktail machines. To do this, we use professional industrial PCs with a powerful machine control system. At the same time, the large color touchscreen on the machines keeps the operation very simple and user-friendly.

New developments in the system, such as updates or modifications, can be easily integrated into the existing systems. In addition, TenderOne can access the systems remotely at any time, allowing us to always provide remote service. This makes your TenderOne cocktail machine easily undergo updates, and your machine can last for decades.

Powerful electric pumps

There are different ideas about the use of pumps. Therefore, TenderOne has run tests with various types of pumps over the years, to make our machines as efficient as possible. In the beginning we used compressed air driven beverage pumps. These are the most commonly used pumps in the dispenser technology. Magnet valves regulate the compressed air driven by a compressor, making the system very powerful and efficient. However, this design has the disadvantage that it only works when all parts in the circuit function properly. As soon as the compressor falls away or a pump piece goes down, the entire system is interrupted by interrupting the compressed air circuit for all pumps. Another drawback was that the magnet valves turned out to be a weak point, they had to be replaced regularly and proved very sensitive to small particles such as the pulp of juices.

From that experience we have developed our systems and are now running the TenderOne cocktail machines on electric pumps. To do this, we use Flojet robust double diaphragm pumps. Flojet is one of the largest manufacturers of professional pumps worldwide. Their pumps are very durable and require little maintenance, so that the cocktail machines keep working smoothly for years. Because of this we have managed to keep the maintenance costs of our cocktail machines very low.

Eight pumps are installed per system in collapsible pump racks. If an error occurs with one of the pumps, we can easily reach the pumps and possibly repair or replace them. In addition to the pumps, the flow meters are also located in the pump racks. These meters take care of the empty notification signal. By assembling these parts together in an accessible location, maintenance is very easy and efficient.

Programming and dosing
Your own favorite cocktail recipes are easy to program by the specially developed software of our cocktail machines. In addition, TenderOne offers the possibility to program our prescription in advance, or to add or modify recipes remotely at a distance (by phone).

But of course we know like no other that guests sometimes have special requests. For example, because their favorite cocktail is not on the menu, if they have an allergy or if they want their cocktail just a little bit different. That’s why we developed the TenderOne composer. With this system you can create a cocktail in the system and optionally store it in the device in no time. If desired, this function can also be set off, so you can limit yourself to a standardized menu. Of course, a connection to your point-of-sale system is also possible for this function.

In the dosage of your cocktails we distinguish ourselves from our competitors. The TenderOne is the only cocktail machine that keeps a precise record of flow rates. In other systems the quantity dosage takes place on the basis of time. Calibration then determines the time it takes to tap a preset amount of an ingredient. However, that method has the disadvantage that when the flow rate changes (as is often the case with syrups), the delivered quantity also changes. As a result, your recipe is no longer consistent and the taste of the cocktail can vary. Due to our exact volume measurement, TenderOne does not have this problem. This means that product thickness hardly plays a role and a consistent taste of your cocktails is guaranteed!


No matter how busy it is, TenderOne always offers the possibility to easily check the volume of the connected ingredients at any time. In addition, the cocktail machine sends an empty notification message in time,when an ingredient threatens to run out. When an ingredient is actually on, our system also detects this immediately and displays a message on the touchscreen. At the same time, all recipes in which this ingredient is processed are marked red on the screen.

We understand like no other that there are situations where it is not possible to replace the missing ingredient directly. That’s why our machine still allows you to tap the red-marked cocktails and then add the missing ingredient manually. Once the missing product is finally completed, the red-marked cocktails will be visible again and your menu will be complete again.

Our evaluation module is a comprehensive control tool. You can see the cocktail sales in quantities, times and you can evaluate these dates. Whether you’re selling monthly, weekly, daily or hourly, the module helps you identify the peak demand and set up your bar as efficiently as possible. Of course, the quantities of cocktails consumed are recorded exactly. This helps you with your personnel and material planning. The machine also determines the consumption of the individual products. This makes ordering the right ingredients child’s play.
