Short answer

Choose by target water temperature, tank volume and seafood loading. In tropical Singapore, Hong Kong and Malaysia projects, select one size larger when the tank has high ambient heat or frequent seafood loading.

Match model size to real tank conditions

For Singapore seafood market stalls, Hong Kong live seafood restaurants and Malaysia seafood holding tanks, the same water volume can need different cooling capacity because room temperature, sunlight, pump heat and seafood loading are different.

Scene keywords to consider

Common searches include Singapore seafood market chiller, Hong Kong seafood restaurant tank chiller, Malaysia lobster tank chiller, supermarket live seafood chiller and hotel seafood display tank cooling.

Why leave capacity margin?

If the tank is in a hot shopfront, receives new seafood several times a day or needs a lower water temperature such as 5°C to 12°C, choosing one size larger helps the inverter compressor run with steadier output and better energy efficiency.
