Efficiency and sustainability

The ECOi-LOOP-N EVO water source heat pump is equipped with an Inverter rotary compressor and an EC fan. This offering low energy consumption and very high efficiency levels.
This unit also operates with R513A. A non-flammable and sustainable low GWP (631) refrigerant.
Extra silent unit

The compressor section is thermally and acoustically insulated with 15mm thick Isofeutre. A silencer (on the discharge) or/and a complete insulation of the ventilation compartment can be added as options to reduce even more the sound level.
Ease of installation and maintenance

This new generation of water source heat pump has been designed for an easy false ceiling integration and an easy access to the internal components. The unit is only 250mm high. It is equipped with large removable panels. The filter is accessible from three sides.
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.

The ECOi-LOOP-N EVO is the new generation of water source heat pumps. It is available in a single size and equipped with a low energy consumption EC fan and an Inverter rotary type hermetic compressor automatically adapting its speed according to the needed capacity. It offers comfort, energy-efficiency and effective cooling and heating.

Operating with R513A, this water source heat pump is 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 an Inverter rotary type hermetic compressor, a cycle reversal valve (for heat pump units only), a water/refrigerant heat exchanger, a liquid receiver, a thermostatic expansion valve and a finned coil. The casing is made of galvanised steel sheets. 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.

Available with a large range of accessories/options and in multiple air blowing and water connection configurations, ECOi-LOOP-N EVO will adapt to all your projects
