EXINDA Aura 25,000 Btu/h Vertical Stack Plus Heat Pump ERV (HPERV)
More room to live. More capacity for comfort.
Give larger living areas and multiple bedrooms the comfort they need. EXINDA AURA 25,000 Btu/h Vertical Stack Plus combines a higher cooling-capacity option with heating and fresh-air ventilation for spacious condos and apartments. One floor-standing cabinet serves the home through ductwork, keeping the main unit out of the ceiling and service components within easy reach—without a separate outdoor condenser.

ERV data: the ventilation section is EXINDA's HVI-listed Breeze ICMBCOFF1AYS energy recovery ventilator, HVI ID 2005500. The packaged AURA itself is not HVI listed because the HVI test procedure is written for ventilators with four duct connections, and the packaged unit has more. Listed fan power was measured with the maximum-capacity blower configuration; contact EXINDA for fan power at your design airflow and external static pressure.

AURA Selection Questions
When should I choose this higher-capacity model?
Consider it for larger living rooms and homes with multiple bedrooms that need more cooling capacity. A ducted layout distributes air across the home; the room loads and floor plan guide the final choice.
How do I choose between ceiling and floor-standing installation?
A vertical cabinet is practical where ceiling depth is limited and the layout provides a dedicated equipment space. It keeps the main unit accessible at standing height; the room ducts still need a planned route.
Where should the equipment sit within the home?
Choose an accessible service position away from bedrooms and main seating areas where possible. Allow room for the cabinet, duct connections and maintenance, with suitable vibration isolation.
What needs to connect to the outside of the building?
Separate outdoor intake and discharge ducts connect the indoor unit to exterior air openings or a coordinated louver assembly. There is no separate outdoor condenser. Plan the openings, duct insulation and separation as part of the façade design.
How does the built-in ERV support fresh air and bathroom extraction?
The ERV brings in fresh air and extracts stale air while recovering energy. Bathroom extraction can be connected as part of the ventilation layout, with airflow and controls coordinated for the dwelling.
How much floor space should we reserve for the unit?
Allow a dedicated position for the 32 × 24 in. cabinet footprint and 84 in. height, plus access around the service panels. Keeping the unit at floor level frees the ceiling from the main cabinet, while ductwork distributes air to the larger living area and bedrooms.
How is routine maintenance kept accessible?
Leave a clear service area at the cabinet so technicians can open panels, remove filters and reach components without working overhead. Include this access space in the equipment layout.
Which electric heating options are available?
Optional 3, 4 or 5 kW electric auxiliary heating can be selected to suit the home’s heating needs and electrical supply.
Can different apartment layouts use different AURA models?
Yes. A development can combine different capacities and installation formats. Share the location, floor plans and dwelling mix so EXINDA can help compare models and provide the technical information for your project team.
