invisible water-based air conditioning with circular management of water resources
IDRA R3 evolves the concept of air conditioning without an external unit, integrating an intelligent system that reduces water consumption, prolongs its reuse and makes it available for other domestic uses.
Designed for buildings subject to environmental regulations and environments where the installation of external units is not permitted, IDRA R3 expands the application possibilities of the IDRA system and introduces a new system logic: water is no longer just a heat exchange fluid, but a resource to be valorized in a circular way.

No external drive
An invisible solution designed for listed buildings, prestigious facades, and contexts where aesthetic impact must be minimized.
Reduction of water consumption
The R3 module allows you to reuse water multiple times, limiting withdrawal from the network and improving the overall efficiency of the system.
Integrated thermal reserve
The storage tank allows the machine to be kept within the correct operating range and makes hot water available for other uses.
Installation flexibility
The system adapts to different configurations and simplifies the work of installers and designers in both new and renovation projects.
IDRA: the technological basis from which the R3 evolution is born
IDRA is the invisible water-cooled condensing air conditioner designed to be installed entirely inside the home, for example under the sink, in a bathroom vanity, or in a utility room. This solution is designed to meet the needs of all those settings where installing external units is not possible or where the visual impact of the system is a design limitation.
Available in single, dual, trial, and quad-split versions, IDRA combines Full DC Inverter technology, quiet operation, A++ energy efficiency, and exceptionally discreet installation. With the R3 project, Tekno Point takes another step forward: the system no longer simply uses water as a heat exchange medium, but manages it in a more advanced, efficient, and responsible way.

The challenge
In traditional water systems, water resources are often used without any real optimization logic. This can lead to:
- increased water withdrawal from the network;
- lower valorization of the energy contained in the water used;
- less efficient systems overall;
- fewer opportunities for integration with other domestic uses.
Tekno Point's response
With R3 – Reduce, Reuse, Recycle , Tekno Point introduces a system that applies the principle of water circularity to HVAC systems. The result is a solution capable of:
- reduce water consumption;
- reuse the same resource multiple times;
- recover water for other technical and domestic uses;
- maintain high air conditioning performance within its ideal operating range.
R3: the evolution of IDRA
The R3 – Reduce, Reuse, Recycle module is based on the principle of water circularity applied to CVC (HVAC) systems, introducing a more advanced, efficient and sustainable management of water resources within the system.
REDUCE
Reduces water withdrawal from the network
REUSE
Reuse the same water several times to operate the air conditioner
RECYCLE
Recovers and valorises used water by allocating it to other domestic uses
With a concrete sustainability focus, IDRA R3 allows you to reduce water consumption without compromising comfort and system performance. From a hydraulic perspective, the module integrates a closed circuit with a storage tank, which acts as a thermal reserve and allows for more efficient water management than a traditional, simple-to-use and drain-out system.
The water used by IDRA is stored and reused until it reaches the optimal operating temperature, thus keeping the machine within its ideal performance range. Only when necessary does the circuit open to renew the water, then automatically return to a closed configuration and continue the usage cycle.
For the user, this evolution translates into concrete advantages:
- a reserve of hot water available at no additional cost;
- a significant reduction in water consumption;
- an improvement in the overall efficiency of the plant.

The IDRA R3 system is based on advanced water management, designed to maximize circuit dwell time and minimize water consumption. Its operation is guaranteed by three key elements:
- a technical storage tank sized according to the available space;
- electronic management of the recirculation cycle;
- hydraulic integration with domestic uses.
The hot water produced by IDRA can therefore be reused in various areas of the home:
- supply of toilet cisterns;
- filling washing machine and dishwasher;
- preheating of a DHW system;
- garden irrigation or other technical uses.
This logic allows the circuit to be kept closed for longer, allowing IDRA to operate with almost zero water consumption for extended periods, improving the overall efficiency of the system and reducing the impact on water resources.
