6.4.1 ECO LOCK® QUICK COUPLERS
ECO LOCK® is the INTELLIGENT COUPLER, Brain Bee patented, that with the suitable automated
procedure in the software enables to:
1. reduce the formation of non condensable gas inside the vessel ;
2. avoid refrigerant dispersion in the air during disconnection ( puff effect);
3. check possible SCHRADER valve leaks before disconnection.
The ECO LOCK® quick couplers accomplish ground-breaking functions, for which they are
conceived, only if the ECO LOCK® function is enabled within the “SETTINGS” menu – “ECO
LOCK” submenu of the specific equipment.
