Volume heat exchanger

Product description

The horizontal positive displacement heat exchanger is used to heat the water in the tank layer by layer until the outlet reaches the set temperature and produces domestic hot water. The displacement heat exchanger with floating coil is a new type of hot water equipment, which is widely used in school, hospital and hotel.

Product features 

● the heat medium temperature drop of the positive displacement heat exchanger is large. During the heat exchange of steam and water, the outlet temperature of condensate water is about 50 ℃, and the upper and lower parts of return water pipes need to be equipped with traps to facilitate the use and maintenance. During the heat exchange of water water, the temperature drop is 2-2.5 times of that of the same type of heat exchanger, and after the heat exchange of 120-150 ℃ high temperature hot water, it can be reduced to 70-75 ℃.

● the positive displacement heat exchanger has good heat exchange effect, good heat dissipation effect, small heat loss and energy saving. At the same time, when the steam is used as the heat medium, about 15% of the heat of condensate can be recovered.

The cold water area is small and the volume utilization rate is high.

The utility model has the advantages of large water storage, low head loss, safe and stable water supply and convenient scale removal.
