Cellarbuoy SAFEFOB - Foam detector for cold room
The CellarBuoy SafeFob foam detector offers superior safety and is vital for controlling foam when dispensing beer and kegged beverages to tap, ensuring impeccable, satisfying service.
The Cellarbuoy* SAFEFOB (Fob Detector, beer monitor) is a mechanical device designed to keep beer lines balanced and stable (circuit full of keg beer ready to dispense) by preventing gas from entering the beer line when the keg is empty.
It prevents excess gas in the line and therefore significantly reduces beer waste and downtime when changing kegs. The bottom of the float has a conical base to seat the ball at the bottom, preventing the float from drifting off center in the Cellarbuoy.
Purge button valve to release excess gas. Prevents accidental emptying of the new keg thanks to the automatic spring‑loaded shut‑off.
