The Enervent Pegasos Z HP unit is best suited for large detached houses and public spaces, such as schools and kinder gardens. Pegasos Z HP has a built-in extract air heat pump (HP). All heating and cooling coils, as well as the heat pump unit, are built-in to the unit.

The Pegasos Z HP with a built-in heat pump effectively cools and heats the air on demand. The cooled and heated air is evenly distributed throughout the building via the ventilation ducts (not local point formed distribution, as in traditional heat pumps).

Enervent Pegasos Z HP is a ‘non-residential ventilation unit’ (NRVU) according to the EU Commission Regulation No 1253/2014. Ventilation units with maximum flow rate between 250 and 1 000 m3/h which the manufacturer has not declared intended as being exclusively for a residential ventilation application are called non-residential. Non-residential ventilation units (NRVUs) are excluded from EcoDesign labelling. Our calculation software Energy Optimizer reports whether the chosen NRVU unit fulfills the EcoDesign requirements or not for the intended project.
