Core versus Aero
Both are concealed ducted ONYX NOVA systems installed separately from the air-conditioning system. The difference is emphasis: Core is recirculation-led with controlled fresh-air mixing; Aero is fresh-air-oriented with integrated energy recovery.
Side by side
Published data and design intent.
| ONYX Core | ONYX Aero | |
|---|---|---|
| Primary role | Recirculated indoor-air dehumidification and filtration | Filtered fresh air, exhaust, dehumidification and total-heat recovery in one unit |
| Dehumidification capacity | Core 48: up to 48 L/day · Core 70: up to 70 L/day · Core 120: up to 120 L/day (rated conditions) | Up to 70 L/day at 30 °C and 80% RH |
| Nominal airflow | Core 70: approx. 550 m³/h · Core 120: approx. 1,000 m³/h | 550 m³/h recirculation in dehumidification operation |
| Fresh air | Core 70 and Core 120 accept a controlled quantity of outdoor fresh air mixed with indoor return air; Core 48 subject to confirmed project design | Fresh-air supply 450 / 315 / 225 m³/h with balanced exhaust 400 / 280 / 200 m³/h |
| Energy recovery | Not applicable | Total-heat (enthalpy) exchange core between the separated supply and exhaust streams; 56% summer and 66% winter enthalpy exchange efficiency under rated test conditions |
| Installation | Concealed, with dedicated ONYX Core return and supply ductwork | Concealed, with dedicated indoor supply and return ducts and dedicated outdoor intake and exhaust ducts |
| Typically considered when | Indoor humidity, mould, musty odours and interior protection are the priority | Continuous fresh-air treatment and ventilation quality are the priority |
Technical note: This comparison is an initial guide. Final selection requires a review of the property, moisture load, fresh-air requirements and proposed duct design.
Important
Fresh-air capability is not exclusive to Aero.
Core 70 and Core 120 both process a controlled quantity of outdoor fresh air mixed with indoor return air at the unit inlet. The allowable quantity depends on incoming outdoor-air temperature, relative humidity and system design. Aero adds a total-heat exchange core between the separated supply and exhaust streams; recovery performance depends on outdoor conditions, airflow rates and system design, and no reduction in electricity consumption is published without a project-specific calculation.
