SFQ series horizontal storage floating coil heat exchanger
1、 Product Introduction
The SFQ series horizontal storage floating coil water heater adopts the superior heat transfer method of SFP and LFP horizontal floating coil heat exchangers, and considers storage heat exchangers that meet certain water storage requirements. It has the following characteristics:
1. The heat exchange element of the equipment is a spiral floating coil bundle, which has a similar heat transfer coefficient and automatic descaling function to the SFP series, making it easy to maintain and has a long service life;
2. This series of products has a certain volume, and the water storage part has a hot water capacity of 10-30 minutes. The head loss of the heated water is small and can be ignored. The water supply is stable, and with the installation of a general automatic temperature control valve, it can ensure water safety and energy efficiency;
3. The heat exchange tubes are evenly distributed inside the tank, with no stagnant water and relatively few cold water areas.
4. The shell and coil of this product are mainly made of stainless steel and copper tube, which completely solves the problem of yellow water affecting water quality caused by corrosion inside the shell;
5. This series of products are all equipped with maintenance manholes for easy maintenance, without the need to reserve maintenance space, minimizing the occupation of machine room area.
2、 Heat exchange principle
During the heating process of a floating coil, the centrifugal force generated by the flowing heat medium inside creates a high-frequency vibration in the coil, which expands and contracts freely with changes in water temperature, causing disturbance to the heated medium and disrupting laminar heat transfer.
3、 Unique automatic descaling function
During operation, the frequent vibration of the spiral floating coil and its free expansion and contraction with water temperature cause the scale that may form outside the coil to automatically fall off, without the need for special descaling measures, interrupting normal water use and ensuring the heat transfer performance of the equipment.
4、 Applicable places
This heat exchanger is suitable for hot water supply systems in general industrial and civil buildings. When the heat medium is saturated steam, its steam pressure is 0.4-0.6MPa; When the heat medium is high-temperature water, the temperature is less than 150 ℃ and the pressure is less than 1.6MPa. Users should indicate the working pressure of the tube and shell side and the type of heat medium when selecting.
