📋 Overview
The CH-HRV4K2 is a supply & exhaust ventilation unit with heat recovery (recuperator) from the Cooper & Hunter brand. It is designed for residential or light-commercial premises, providing fresh air intake and exhaust of used air, while recovering thermal energy. It’s suitable for smaller apartments, houses or offices.

🔧 Key Specifications
Here are some of the technical details I found:
Maximum air flow / capacity: ~ 400 m³/h.
External static pressure (approx): ~ 80-90 Pa.
Heat recovery (plate/cross-flow) efficiency: about 74-76% (in at least one source)
Power consumption (without heater): about 150 W
Unit dimensions: e.g., 744 mm × 804 mm × 270 mm (or similar) in one listing.
Weight: ~ 31 kg in one listing.
Installation: suspended / ceiling-type installation. Duct connection diameter ~ 250 mm in one listing.
Operating temperature range: one listing suggests from –15 °C to +50 °C.

✅ Features & Highlights
Compact size, suitable for installation in suspended ceilings or concealed spaces.
Built-in heat recovery (recuperator) to reduce heating/cooling load by pre-conditioning fresh air.
Likely includes features like automatic control, bypass for summer, filter change indicator, possibly frost protection.
Possibly supports integration with BMS or external control systems (depending on model/configuration).
Designed for quieter operation in residential/office environment.

⚠️ Notes & Considerations
The data available are from non-English sources and may vary depending on specific variant or regional version. Always verify with official datasheet.
The “4K2” suffix suggests a particular generation/series — ensure the version you buy matches your requirements (airflow, static pressure, controls).
For optimal performance, duct sizing, filter maintenance, and correct installation (including bypass/frost control) are important.
The “suitable area” depends on air change rate, ceiling height, building envelope, so just based on 400 m³/h you’ll need to calculate for your space.
