Run Around Coils
Heat recovery run around coils are designed for a closed-loop water/glycol circuit, to recover heat from building extract ventilation systems and preheat the fresh air supply. HC Coils run around coils are designed to achieve high efficiencies as required by the Ecodesign Directive 2009/125/EC – 68 % Efficiency based on equal Supply and Extract Air Volumes with supply air inlet + 5°C and Extract Air at + 25 °C.
