Refrigerated seawater

A trusted system along the Norwegian coast.

RSW systems on CO₂ (R744), with titanium heat exchangers designed and built by Tempia in Svolvær.

Outline of the Norwegian coast
100+vessels along the Norwegian coast run CO2PRODots are illustrative, not vessel positions.

Five sizes, NG588 to NG9826

RSW systems for small fishing vessels through to large fish processing plants. Heat exchangers with a PE shell and titanium core, 304 stainless steel pipework and frame, and PLC control with an HMI (operator screen).

Nominal capacity at the data sheet’s stated conditions: arctic at 16 °C seawater, tropical at 28 °C, tank +0.2 / −1 °C. Actual performance depends on the operating case. Temperature setting −1 °C to +40 °C, all sizes.

PLC control and HMI

PLC control with an HMI (operator screen) and integrated flow measurement, developed in-house. Temperature, flow and system status are shown on one screen. Tempia valve control can use the same interface.

The control panel from a CO2PRO RSW plant. The values are simulated, not a plant running right now — try the setpoint and watch the plant respond.

Titanium, built in Svolvær

Designed and built by Tempia for seawater applications. Compact units for the available machinery space. Tempia supplies the heat exchanger, its documentation and its spare parts.
