Maintain freshness and reduce loss. A fine bubble system that efficiently maintains dissolved oxygen in the live fish tank.

In the operation of restaurant chain stores, maintaining the quality of live fish managed in tanks is a crucial factor that influences the value of the dishes served. Particularly during high-density storage or in the summer when water temperatures are high, the decline in dissolved oxygen can lead to reduced vitality and mortality of the fish. To preserve freshness and ensure a stable supply of ingredients, it is essential to create an environment that efficiently maintains dissolved oxygen levels in the tanks. Nakajima Bussan's fine bubble system supports the maintenance of dissolved oxygen through fine bubbles, helping to suppress the decline in vitality of the fish during storage. 【Usage Scenarios】 - Storage of live fish in in-store tanks - Oxygen supply during high-density storage - Low oxygen countermeasures in summer 【Effects of Implementation】 - Supports the maintenance of fish vitality - Reduces losses due to weakness and mortality from oxygen deficiency - Contributes to the reduction of oxygen usage
