LUFT-WASSER-KÜHLGERÄTE – QU4TRO K4A

Adaptation and environment

• Reduced charge of low-GWP HFO refrigerant R-1234ze minimizing CO₂ footprint
  (99.9% lower GWP than R-410A and 99.5% lower than R-32).
• Equipped with the latest generation of hermetic scroll DSG compressors designed in tandem with plate heat exchangers and optionally with the latest generation of multitubular heat exchangers.
• Wide operating range of the outdoor temperature equipment.
• Incorporate the latest generation of AQUAMATIX Siemens modular programmable electronic controllers.

Energy Efficiency

• High energy efficiency at partial load exceeding the seasonal efficiency requirements of the Ecodesign Regulation 2021 (EU 2016/2281) with up to 17% energy savings.
• Electronic fans and electronic expansion valve as standard for minimum energy consumption and electronic condensation control.

Modular Version

Optional modular version (series 1) for modular assembly with easy and fast interconnection, which makes this an effective and simple solution for installations where compact, light, easy to transport and high power equipment is required.

In addition, they offer an important solution for the continuous operation of the equipment without interruption, thanks to their independence of electrical connection, since the failure of one of the modules can be easily repaired without having to stop the operation of the complete modular installation.

Wide range of power due to its modulation, each module reaching a cooling capacity of 124 kW and with the possibility of a maximum of 8 modules.

Heat Recovery

System that uses waste heat from air condensation to heat water for both DHW and industrial applications.

• Recovery of up to 100% of heat energy.
• Free production of high temperature hot water.
• Reduced electricity consumption of the heating system.
• Reduction of fossil fuels and CO₂ emissions with efficient and renewable solution.

Integrated Freecooling

New optional additional free-cooling coils integrated in the unit in the same V’s of the cooling circuit, which allows to take advantage of the energy of the outside air when the external conditions are favorable to carry out the energy exchange with the water of the installation.

Freecooling coils integrated in the same V’s of the refrigeration circuit.
