RV03/04seriesVolumetric heat exchangerIt is a new type of architecture introduced from the Architectural Design Institute of the Ministry of Constructionheat exchangerIt is utilizing“RV-02”After the successful experience of the double tube bundle volumetric heat exchanger series, a new generation has been launched to overcome the disadvantages of old products such as high steel consumption, high requirements for equipment rooms, limited variety and specifications, and high selection limitationsVolumetric heat exchangerAfter thermal performance testing at the North China Testing Center of the Ministry of Mechanical and Electrical Engineering, its thermal performance far exceeds that of other similar products, making it the most ideal and wise unit for hot water use at presentHeat exchange equipment.

Product Features

RV03/04 seriesVolumetric heat exchangerCompared to similar products, it has the following performance advantages:

◆ Adopting small tube diameter heat exchange tube bundle and secondary heat exchange of heat medium;

Adding flow guiding and blocking devices inside the tank significantly improves the heat transfer coefficient;

Adopting a new type of heat exchange tube bundle, multiple processes, and high utilization rate of heat medium;

The cooling effect of the heat medium is significant, which is 1.2 to 2 times that of similar standard tanks;

The cold water area is small, with a capacity utilization rate of 90%;

The comprehensive performance is far superior to similar standard tanks, with high efficiency and energy saving.

Product Types

The RV03 series has 6 specifications based on volume integration, ranging from 1.5m3 to 15m3. Each specification can be divided into steam type and high-temperature softened hot water type according to the type of heat medium in the tube side. Each model is further divided into three types of heat exchange areas: A, B, and C, which are suitable for different hot water production capacities. The RV04 series has a total of 23 specifications ranging from 1.5m3 to 15m3 by volume. There are also two types of heat media, steam type and high-temperature hot water type, available for heating. Each model has four types of heat exchange areas, A, B, C, and D, to meet different hot water needs.

Applicable occasions

This seriesheat exchangerWidely applicable for hot water supply in general industrial and civil buildings, such as hotels, nursing homes, high-rise buildings, sports halls, residential areas, and other industrial water units. Compared with other similar heat exchangers, it has the advantages of small footprint, energy saving, and reliable operation.
