Liquid Temperature Control Unit

Liquid Temperature Control Unit

The liquid temperature control unit (LTCU) provides a cooling liquid flow which is used to remove the heat produced by equipment and sensors and streamed in from the ambient. A typical principle diagram is shown in figure below. The heat is removed to the ships chilled water by the LTCU (right side in the figure). This is referred to as the primary circuit. The liquid flow to the systems is referred to as the secondary circuit (left side in the figure). When the sensor systems are off, and there is no dissipation, the LTCU’s are used to keep the sensor systems on their operational   temperature. The LTCU has a heater for the heating of the secondary cooling liquid. Additional functions of the LTCU are the overpressure protection of the liquid circuit by means of expansion compensation devices and safety overpressure relief valves. For reasons of redundancy and flexibility multiple LTCU’s can be considered.

The LTCU is speciffically suitable for military vessels due to:

  • the compact design
  • electronic magnetic control (EMC)
  • shock qualification MIL-S-901


The casing of the LTCU is built out of a carbonsteel, dipcoatprimed power coated frame and panels out of double heet aluminium with in between a layer Rock-wool 223. The front side of the casing is fitted with a door, which gives ccess for maintenance. The coating is availible in all RAL colors.
