The Brine-to-Air Heat Exchanger enhances the efficiency of MVHR systems by using the earth’s naturally stable underground temperature to regulate the incoming fresh air. Installed ~1.2 m below ground, the collector circuit circulates a brine solution maintained at 8-12°C, transferring thermal energy to the MVHR unit.
During winter, the system provides additional pre-heating, reducing heating demand and helping to prevent frost formation within the ventilation unit. In summer, it cools the incoming fresh air, helping to maintain comfortable indoor conditions and reduce cooling loads.
By lowering energy demand and maximising heat recovery performance, it provides an efficient and sustainable year-round temperature control solution.
Key Features:
- Connect your MVHR unit for enhanced thermal efficiency
- Can be automatically controlled by an Adroit unit
- Brine is kept at a sub-soil temperature of 8 to 12°C
- Provides additional pre-heating to your MVHR unit during the winter
- It also provides cooler air in the summer
- Water temperature gauges monitor the supply and return temperature of the brine
- Fitted with a ISO Coarse 75% (G4) filter
- Wall mounted, 12 litre pressure expansion tank with relief valve included
Brine to Air Energy Collector is delivered as a kit, which ensures full functionality and optimal performance.
Included in the kit:
- Brine to air heat exchanger delivered with ceiling / wall mounting plate
- Hydraulic kit
- Underground collector pipe set
Application:
Ground-coupled air preheating and precooling for residential mechanical ventilation with heat recovery (MVHR), improving thermal efficiency and reducing building's requisite heating and cooling energy consumption.
