Semi-volumetric heat exchangers are equipped with built-in heaters. The primary principle is to enhance the flow rate of the heat medium inside the tubes and the heated water outside, converting laminar flow to turbulent heat exchange. This maximizes the heat exchange efficiency of the tubes, eliminates short-circuiting in the heated water, significantly increases the heat transfer coefficient, thereby enhancing heat transfer efficiency and the amount of heat supplied.

Features of semi-parallel flow heat exchangers:

1The heat exchange section features an improved rapid heat exchanger with a high heat transfer coefficient and a large heat exchange capacity..

2The semi-rectangular feature of the storage section allows for efficient water retention.10-20Minute water flow rate, head loss of heated water ≤0.2Maintains stable water pressure and temperature, safety, water conservation, and comfort in use, even under general conditions for setting automatic temperature control valves.

3The heating section is rapid, the water inside the tank is all hot water, with no standing water or cold areas, and high utilization of the tank's volume.；

4The product can maintain the water temperature inside the tank using the circulating pump on the hot water pipe network when the water usage rate is low or no water is used. The heat exchange section is always in a state of flowing heated water, ensuring thorough heat exchange and energy saving. During steam-water heat exchange, the condensate outlet temperature is lower than80℃；

5Small can shape, lightweight, with heat exchange speed that can be withdrawn horizontally for easy maintenance.

Design specifications for semi-rectangular heat exchangers :

1The semi-compact heat exchanger is suitable for hot water supply systems in general industrial and residential buildings, using high and low temperature softened water as the heat medium, and can be selected according to different heat sources.

2The outlet temperature after being heated with hot water must not exceed75°C, in actual use, to delay scaling, the temperature of the heated water should be controlled at50-60Between ℃. To ensure safer operation, a drain valve must be installed on the heat medium outlet pipe.

3Material; The recommended material for the semi-velocity heat exchanger shell is stainless steel.1Cr18Ni9TiOr imported stainless steel sheetsSUS304; Heat exchanger tube bundle material usedT2Copper tubes and stainless steel tubes. If the user has no high requirements for water quality, carbon steel shells and carbon steel heat exchanger tube bundles can also be used.

4The semi-容积式 heat exchanger should be equipped with a safety device. When installing a safety valve, the opening pressure of the safety valve should not exceed the design pressure (this should be stated when ordering the safety valve), and the installation and use of the safety valve should comply with the provisions of the Ministry of Labor and Human Resources' "Safety Supervision Regulations for Pressure Vessels."
