Antifreezing cold and hot water unit

Antifreezing cold and hot water unit

The seawater heat exchanger and circulating water heat exchanger of this series of cold and hot water units adopt antifreeze type heat exchanger. The flexible medium is attached inside the heat exchanger, which can counteract the expansion force when water freezes, and avoid the hidden danger of heat exchanger freezing crack and unit water entering scrap;
The structure has the characteristics of low height and wide width, which is suitable to be installed in the engine room or empty cabin with low height.
In addition to the antifreeze characteristics, the seawater heat exchanger is different from the method of parallel connection of several small coaxial heat exchangers used by similar products in the market. It also has the characteristics of anti blocking and timely water shortage alarm.
For seawater, seawater heat exchanger can be equipped with titanium tube.
Protection function: seawater high and low temperature protection, circulating water high and low temperature protection, unit high and low pressure protection, seawater circulating water flow protection, antifreeze alarm, compressor pump overload protection
