A suitable seafood tank chiller must be selected from the real heat load, use saltwater-compatible materials and maintain stable water temperature with inverter control.
What is a seafood tank chiller?
A seafood tank chiller removes heat from recirculating water so live lobsters, crabs, fish and shellfish can be held in a controlled environment. Commercial systems are designed around continuous water circulation, ambient heat, livestock load and long operating hours.
Why does stable temperature matter?
Rapid or repeated temperature changes stress live seafood. A well-sized inverter system can reduce overshoot by matching compressor output to the current load instead of repeatedly switching at full capacity.
How to choose the right capacity
Start with the full water volume, target temperature, highest room temperature, tank insulation, pump heat, lighting, fresh product loading and required pull-down time. Nameplate tank volume alone is not enough for accurate selection.
| Input | Why it matters |
|---|---|
| Water volume | Defines the base thermal mass |
| Ambient temperature | Sets the peak heat gain |
| Target temperature | Determines the required temperature difference |
| Saltwater or freshwater | Determines heat-exchanger material |
| Seafood loading | Adds biological and product heat |
Why titanium is used for saltwater
On the water side, titanium is widely selected because it offers strong resistance to saltwater corrosion. That material choice protects the heat-transfer surface and supports longer service life when the system is maintained correctly.
Frequently asked questions
Is a larger chiller always better?
No. Oversizing can increase cycling and reduce control quality. Capacity should be matched to the calculated peak and partial load.
Can one chiller serve multiple tanks?
Yes, when the tanks share a properly designed circulation loop or use correctly balanced independent branches.
What should I send for a quotation?
Send tank volume, target temperature, ambient temperature, water type, species, power supply and photos or a piping sketch.
