Active Inverter Recovery

Innovative Full Inverter Active Recovery System for energy recovery by means of an additional cooling circuit with inverter compressor.

This circuit allows an increase of the nominal power of the equipment, which increases its compactness.

Moreover, since this additional circuit exchanges heat between the fresh air and the extract air, under favorable temperature and humidity conditions, a high cooling performance is obtained.

This increases the nominal efficiency of the unit and the seasonal efficiencies under partial loads.

Furthermore, due to the INVERTER technology, they ensure the correct operation for the minimum flow rates established by the RITE update in 2021, going from an air flow rate of 1800m³/h to 1000m³/h.

Dynamic Recovery

It consists of an energy recovery system by means of an additional exchange coil (subcooler), placed in series with the unit’s air condenser, thus
the air condenser of the equipment, achieving a significant improvement in the efficiency of the equipment by reducing the electrical consumption of the equipment.

This system is advantageous compared to static recovery systems, because it avoids static recovery systems, because it avoids a higher consumption of the supply and return fans, due to the high pressure drop of these of these plate or rotary recuperators.

It can also be installed in units with exhaust fans.
extraction fans.
