Efficiency and sustainability

The ECOi-LOOP-N FS water source heat pumps operate with the non-flammable and sustainable R513A low GWP (631) refrigerant - 3 times less polluting than the standard R410A.
These units can be equipped with low consumption EC fans offering excellent EER and COP efficiency values.
Extra silent units

Two acoustic versions available: standard low noise (ventilation section coated with 15mm thick thermal-acoustic insulation) or extra low noise (ventilation section coated with 30mm thick thermal-acoustic insulation).
All units also have the compressor compartment covered as a standard with a 20mm thick Isofeutre thermal-acoustic insulation
Elegant design

A refined cabinet made of galvanised steel sheets painted RAL9010 allows a harmonious and smart integration of the units in every kind of interiors.
Ease of maintenance

To facilitate maintenance interventions, the front removable panel provides easy access to the compressor, the fan and the electrical box.


Water source heat pumps are perfect for buildings where different zones may have different indoor climate needs. All connected together to a closed water loop, these units have the advantage of operating completely independently. Some can be working in cooling mode when others can be heating.

The ECOi-LOOP-N FS is the new generation of vertical water source heat pumps. The range is available in 2 sizes and operates with the eco-friendly R513A low GWP (631) refrigerant. These units can be equipped either with AC or EC fans and with or without cabinet. They offer comfort, energy-efficiency and effective cooling and heating.

The refrigerant circuit comprises a rotary type hermetic compressor, a cycle reversal valve, a water/refrigerant plate heat exchanger, a liquid receiver, a capillary expansion device, and a finned coil. In their standard version, the units are equipped with a Siemens electronic control system which manages their operation and their safety devices. The condensate drain pan is coated with an anti-corrosion treatment consisting of oven-baked epoxy paint
