SoftDose™
Reliable dosing for hot-fill, powder and granular products.
Dosers
Nitrogen dosers: four models, one precise drop.
JoyCan is an authorized USA distributor of Chart Inc. dosing products — we stock and sell Chart dosers, vacuum-insulated pipe and tanks. Our dosers are Chart dosing systems, engineered and custom-configured by JoyCan and backed by both OEM and JoyCan warranties. Each meters a measured charge of liquid cryogen into the container the instant before sealing. Compare the range, then use the selector to find the model built for your line.
