Volumetric heat exchangers utilize the alternating flow of cold and hot fluids over the surface of a heat storage medium (filling) within a storage chamber to exchange heat. In shell-and-tube volumetric heat exchangers, the cold and hot fluids are separated by solid walls and heat exchange occurs through these walls, hence also known as surface heat exchangers.

Product Features

1. The volumetric heat exchanger has a significant temperature drop in the heat medium. During steam-water heat exchange, the condensate outlet temperature is approximately 50°C, and a drain valve should be installed in the upper and lower sections of the return pipe for convenience in use and maintenance. During water-water heat exchange, the temperature drop is 2 to 2.5 times that of the same type of heat exchanger, and the high-temperature hot water at 120 to 150°C can be reduced to 70 to 75°C after heat exchange.

2. Volumetric heat exchangers offer excellent heat exchange performance, efficient heat dissipation, minimal heat loss, and energy-saving features. Additionally, when using steam as the heat medium, they can recover approximately 15% of the total heat exchange amount as condensate heat.

3. The cold water zone is small, with a high volume utilization rate.

4. Maintains the advantages of a large water storage capacity, low head loss, safe and stable water supply, and ease of scale removal for volumetric heat exchangers.
