Volumetric floating coil heat exchanger High-efficiency volumetric floating coil heat exchanger
The floating coil heat exchanger adopts the form of a cantilever floating coil. When the steam heats hot water, the coil floats up and down. Allowing water flow around the coil destroys laminar heat transfer. The heat transfer capacity is greatly improved, the heat transfer coefficient/㎡℃. At the same time, due to the scouring effect of the water flow, the tube can be cantilevered to float freely and expand and contract freely, so it is not easy to accumulate scale. If a small amount of scale accumulates during long-term use, it will pass through the tube. The expansion will automatically descale, so the heat exchange capacity will not decrease after long-term use, and the effect is good. In the heat exchanger family, the floating coil heat exchanger is favored by users because of its unique heat exchange elements, which have many advantages that other forms of heat exchangers do not have. In the production and manufacturing process of more than ten years, our company has carefully summarized its own experience, collected market feedback information, and continuously optimized and improved it to make its structure more reasonable and its performance more superior. According to our company's research and development process and market demand, the sixth generation product has been launched.
Floating coil volumetric heat exchangers have a certain water storage capacity and are more widely used in domestic hot water supply systems in industrial and civil buildings such as hotels, restaurants, schools, hospitals, factories, and mines.
The heat exchange element of the heat exchanger is a copper tube, and the shell material is divided into two types: carbon steel and stainless steel. It can also be carbon steel lined with copper plates or stainless steel plates.
The heating medium is steam or high-temperature water, and the working pressure on the tube side is not higher than the working pressure on the shell side.
In order to prevent the equipment from overpressure operation, it is recommended to install a safety valve on the top of the heat exchanger, which is economical and safe and does not occupy additional space. In order to control the outlet water temperature within the required range, a temperature sensor interface is provided on the shell near the heated water outlet to effectively control the heat medium flow.
The heat exchange element of this series of heat exchangers is a floating coil tube fixed at both ends. Under the influence of the temperature and pressure changes of the heat medium in the tube and the impulse of the heated water in the shell, it can produce high-frequency vibration, causing the heated material to vibrate. The disturbance of the water not only enhances the heat transfer effect, but also makes it difficult for scale to adhere to the outer wall of the coil, realizing the automatic descaling function.
This series of heat exchangers has complete models and numerous specifications. Our company can design and calculate different tank volumes, working pressures, heat transfer areas and heat transfer products according to user requirements!

Technical Features
The heat transfer coefficient is high. When exchanging heat with steam and water, ~kcal/square meter hour~Watt/square meter. When exchanging heat with water, ~kcal/square meter~ W/m².
The water storage capacity is large, there is basically no dead water area, the volume utilization rate is high, the water head loss is small, and the water supply is safe and stable.
There is no need to reserve space for the pumping tube bundle, and it occupies a small area.
Since the heat exchange coil can float and freely expand and contract in the shell, the heating medium and the heated water are disturbed, which improves the heat transfer efficiency and makes the heat exchange more complete. One-stage heat exchange can meet the usage requirements. During the heat exchange between steam and water, the temperature of the condensed water can be dropped below ℃, thus fully saving energy.
It can continuously and automatically detect the outlet water temperature, and instruct the control valve to adjust the flow of heat medium entering the coil to achieve precise temperature control. Even under load fluctuations, the outlet water temperature can be maintained within the °C range of the set value. This function is not inherent in the equipment, and the user must purchase a temperature control valve.
It has the function of automatic descaling, no impact noise during operation, easy maintenance and management, and long service life
