Product & Service

Liquid Nitrogen Freezer

Liquid nitrogen quick freezer uses liquid nitrogen spray freezing technology, that the -196℃ cryogenic liquid nitrogen is sprayed into mist through specialized nozzles and exchanges heat with the food to freeze food very quickly. QUICK FREEZING generates tiny ice crystals within the cells of food, can keep the food fresh and nutritious.

Dry Ice Maker

The raw material Cryogenic LIQUID CO2 is physically converted into Solid CO2 (dry ice snow) and gas CO2 in the ice generator of dry ice production machine after CO2 throttle and depressurization, then the dry ice maker presses low-density dry ice snow through different dry ice molds to produce high-density dry ice blocks or pellets.

Dry Ice Cleaner

Dry ice cleaner accelerates and sprays -78.5℃ DRY ICE particles to achieve efficient and non-destructive cleaning purpose through the physical effects of low-temperature embrittlement, impact peeling and sublimation purge. Dry ice blasting is 100% chemical-free and environmentally friendly physical cleaning method.
