Sizes on this catalogue run 666 g, 2 kg, 4.33 kg, 5 kg and 10 kg. Picking one is a throughput question. How much cream, foam or infusion work goes through the bench in a week, and how much interruption a unit change causes mid-service.
The 666 g Smartwhip charger is the smallest listed unit. It fits a kitchen running compatible dispensing equipment at ordinary volume -- a cafe, a bar finishing a modest number of drinks, a pastry section working plate by plate. Easy to store, easy to keep a spare of.
Two kilogram chargers cover most professional kitchens. A restaurant with a dessert menu, a high-turnover cafe, a caterer prepping off-site: all typically settle here. Several brands are listed at 2 kg, so the deciding factor is usually the equipment already in place.
The 4.33 kg unit exists because some benches change a smaller charger more than once a service. If that is the situation, this size removes the interruption rather than adding capacity for its own sake.
Professional N2O tanks at 5 kg and 10 kg change the picture: a compatible regulator becomes necessary and storage needs planning. They earn their place only where the volume is steady and high.
Check any size against the current manufacturer instructions for your regulator or siphon. Send us the model and we will confirm the fit before you order.
