Run Around Coils

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 ErP Directive 2005/32/EC – 68 % Efficiency based on equal Supply and Extract Air Volumes with supply air inlet + 5°C and Extract Air at + 25 °C.

Run Around Coil Pump Sets
HC Coils range of Run around Coil Pump Sets are engineered to provide a cost effective pump package for Run Around Heat Recovery Systems. There are 9 Models in the range to suit flow rates from 0.4 to 7.6 l/s @ 210 kPa.
