ADAPT MAX - COMMERCIAL HEAT PUMP
ADAPT MAX is more than just a heat pump – it's an innovation designed specifically for large buildings. With its modular design, as simple as building blocks, it allows for easy configuration, seamless operation, and one of the highest energy efficiencies in its class. Thanks to its advanced technology and exceptionally low noise level, it's the perfect choice for environments where silence is crucial, while its sleek design sets new standards in the industry.
Simple as a game of building blocks
With ADAPT MAX, heating and cooling transform into more than just a technologically advanced process—they become a game of building blocks, where energy efficiency, environmental friendliness, and aesthetic excellence come together in perfect harmony.
Modular Reliability
Modularity can be imagined as a game of building blocks. The modular design allows the system to be assembled from smaller ‘blocks,’ known as modules. This innovative setup offers exceptional system reliability. If one module stops functioning, the remaining modules continue to operate, ensuring that the system as a whole remains reliable and functional. Modules can be swapped using the ‘hot-swap’ principle, without interrupting the system’s operation.
Refined Design
ADAPT MAX, with its sleek and sophisticated design, continues the legacy of the ADAPT heat pump line and sets new aesthetic standards. Its award-winning design, that won awards such as the prestigious Archiproducts Design Award, seamlessly complements modern architectural trends. There’s no need to hide this unit; ADAPT MAX becomes an elegant feature that blends harmoniously with its surroundings. Perfect for urban and contemporary residential, educational, public, commercial, and tourist spaces, it offers both functionality and visual appeal. The color and material of the casing can be fully customized, ensuring seamless aesthetic integration for every project.
Simple Installation
Thanks to its modular design, ADAPT MAX is installed in the same way as residential heat pumps, making the entire process familiar and requiring no additional training for installers. It is delivered as a pre-assembled system, ready for quick installation. All key components are already connected and tested, significantly reducing the chance of errors during setup. The only steps needed on-site are connecting two pipe connections, the power supply, and the communication cable. This approach ensures a fast and reliable installation without the need for extra adjustments or technical interventions.
300.000x Less Global Warming
ADAPT MAX uses the environmentally friendly natural refrigerant R290, which has an exceptionally low global warming potential (GWP). In the new generation of heat pumps, its GWP is up to 300,000 times lower than that of comparable heat pumps using synthetic refrigerants. Conventional synthetic refrigerants, if leaked, pose a significant environmental burden due to their high GWP of around 1,000. In contrast, R290 has a GWP of just 0.02, making it a far more eco-friendly alternative. Additionally, the use of R290 exempts ADAPT MAX from the F-gas reporting regulation.
