The catalogue offers 666 g, 2 kg, 4.33 kg, 5 kg and 10 kg. None is superior. The decision rests on how much cream and foam work passes over the bench and how disruptive a unit change becomes during service.
The 666 g charger suits a bench working plate by plate: a patisserie finishing to order, a cafe, a bar preparing a modest number of drinks on compatible dispensing equipment. It stores easily and a spare takes no room.
At 2 kg the assumption is steady daily work. A restaurant with a dessert section, a busy cafe, a caterer preparing for an off-site service. Cream Deluxe, FastGas and Lachgas all appear at this size, so the equipment already in place usually settles the choice.
The 4.33 kg unit exists for benches changing a smaller charger more than once in a service. That interruption, rather than capacity alone, is what it solves.
Professional tanks at 5 kg and 10 kg ask for a compatible regulator and considered storage. They reward genuinely high, consistent throughput and little else.
Whichever size you settle on, confirm it against the current manufacturer instructions for your regulator or siphon. Send the model and we will check the fit before the order is prepared.
