A unique market solution

ECOi-LOOP-N water source heat pumps operate with the non-flammable and eco-friendly low GWP R513A refrigerant. Combined with high capacities up to 14,6kW, these two features offer a unique product range on the market.
High efficiency

These units benefit from very high efficiency levels. They are equipped as a standard with low consumption EC fans and have excellent EER and COP efficiency values.
Increased sturdiness

The water/refrigerant heat exchanger is of copper/stainless steel coaxial type for an increased sturdiness at very high pressure.


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.

ECOi-LOOP-N units are available in 6 sizes and equipped with low energy consumption EC fans. The scroll type hermetic compressor, mounted on shock pads, is integrated in a compartment coated with a reinforced acoustic insulation. These units offer high capacities, comfort, energy-efficiency and effective cooling and heating.

Operating with R513A, ECOi-LOOP-N water source heat pumps are also environmentally friendly. With a GWP (Global Warming Potential) of 631, this refrigerant is 3 times less polluting than the standard R410A.

The refrigerant circuit comprises a scroll type hermetic compressor, a cycle reversal valve, a water/refrigerant heat exchanger, a thermostatic expansion valve and a finned coil. Wide removable panels make it easy to access the compressor, fan and electronic control box. 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.
