Heat recovery from wastewaterNX AquaCond
Recover energy and reduce operating costs
AquaCond from Menerga utilises the thermal energy from wastewater. Whether it is pool water replenishment, showers or cleaning processes, usable heat is generated everywhere, which AquaCond recovers efficiently. The compact system is economical, sustainable and pays for itself on average after around four years.

Short payback period
Profitable in less than 4 years
Low operating costs
Through high heat recovery
Flexible integration
For new builds, renovations and existing systems
Compact design
Uniform casing for all power ratings
Technology that makes efficiency visible
Every component carefully thought out
AquaCond impresses with intelligent details such as automatic cleaning, control technology and compact design, for consistently high performance and easy maintenance.

Intelligent flow control
An integrated control system dynamically adjusts the flow rates to the current wastewater volume – for consistently high efficiency and reliable operation, even with fluctuating usage.
Automatic heat exchanger cleaning
The automatic cleaning system with cleaning balls automatically removes deposits from the heat exchanger. This keeps efficiency consistently high, without any manual intervention or interruption to operation.
Corrosion-resistant heat exchanger
Made from a durable copper-nickel-iron alloy – ideal for long-term use with waste water.
Integrated control
The integrated Siemens control system manages the operation of the AquaCond automatically, reliably and efficiently. Thanks to standardised protocols, the system is fully compatible with all common building management systems – for easy integration, transparent monitoring and maximum operational reliability.
Up to 90% less heating energy
Through targeted heat recovery from waste water, AquaCond drastically reduces the energy required to heat fresh water – thereby lowering operating costs.

Heat that would otherwise be lost? Use it now!
Invest intelligently. Benefit sustainably.
Swimming pools generate a considerable amount of warm waste water every day. AquaCond converts this potential into usable energy – efficiently, reliably and economically.

Heat from everyday life
Using wastewater intelligently
Whether from showers, pool water renewal or cleaning: over 85 % of daily wastewater contains usable heat. AquaCond recovers it efficiently and feeds it directly into your system.

Fast amortisation
Quickly paid off
Heat recovery with AquaCond pays for itself – on average after just 4 years. From then on, the system saves money every day and permanently reduces operating costs.
Efficient heat from a source that is available every day
Wastewater becomes a resource
AquaCond harnesses economic potential. The compact heat recovery system extracts thermal energy from wastewater and uses it to heat fresh water. This significantly reduces energy consumption during operation.
The technology is suitable for use in new buildings as well as for the energy-efficient renovation of existing facilities. The combination of a counterflow heat exchanger and a heat pump efficiently recovers existing heat and returns it to the water circuit.

For planners and investors, this means:
Quick return on investment
Minimal operating costs thanks to energy savings
Compact technology that can be integrated anywhere
Automatic ball cleaning for low-maintenance operation
Stays clean. Runs reliably.
Heat exchangers must remain clean in order to maintain their performance over time. The automatic cleaning system takes care of this reliably – without any maintenance breaks or additional effort. This ensures that the system runs smoothly and efficiently at all times.
Cleaning that takes care of itself
The integrated ball cleaning system automatically keeps the heat exchanger free of deposits, without any manual effort. Specially developed porous cleaning balls circulate regularly through the system and reliably remove dirt. This protects the components, extends their service life and reduces maintenance costs to a minimum.

Usable everywhere. Efficient everywhere.
Mehr als nur für Schwimmbäder geeignet
AquaCond was developed specifically for recovering thermal energy from warm waste water and is therefore not limited to use in swimming pools. The system can be integrated efficiently and economically wherever warm waste water is regularly produced – for example, in wellness areas, hotels, sports facilities or industrial applications. Its compact design and high control flexibility make AquaCond the ideal solution for a wide range of applications.
AquaCond utilises what others wash away – everywhere.
