Decentralised heat-recovery AHS
SAV Systems now offers a range of decentralised heat-recovery air-handling units for a wide range of applications from classrooms to offices. Airmaster units are installed in each space to be ventilated and use a connection through an outside wall or roof via a counterflow heat exchanger to the outside. This approach avoids the need for ductwork systems and eliminates the fan power needed to overcome ductwork resistance. Up to 85% heat recovery is achieved.
Further energy savings can be achieved using EC motor technology with low specific fan power. Units can also be combined with CO2 sensors to provide demand-controlled ventilation at a local level.
These units can be used for refurbishment and retrofit as well as new-build projects. They can be mounted at floor level or high level. Floor-mounted units can be configured to provide maximum mixing or displacement ventilation.
