Sisteven displays an opened heat recovery unit whose four chambers are lit in orange, blue, magenta and yellow around a diagonal plate exchanger. Beside it stands a cabinet fan with a transparent side revealing the motor and centrifugal impeller. The backdrop shows airflow labels ODA, ETA and SUP, icons such as 'Energy saving' and 'Low noise level', and www.sisteven.com.
