SFP, LFP seriesHorizontal floating coil heat exchangerIt is a new generation jointly developed by our company and the architectural design institute, based on the absorption of the thermal performance and characteristics of international advanced products such as American AERCOheat exchangerThe product has a novel structure, simple assembly, convenient maintenance and inspection, and excellent performance. It adopts the separated spiral coil technology and is the first of its kind in China in terms of structural form. Having the characteristics of strong instant heating recovery ability, while ensuring stable water temperature control, avoiding complex installation and equipment occupying large spaces, heat exchangers are increasingly becoming the preferred choice for civil, commercial, commercial, and multi-purpose buildings.

Heat exchange mechanism

Floating coilDuring the heating process, the centrifugal force generated by the flowing heat medium inside causes a high-frequency vibration in the coil, which expands and contracts freely with changes in water temperature, causing disturbance to the heated medium, disrupting laminar heat transfer, and significantly improving heat transfer efficiency. The heat transfer coefficient K ≥ 3000W/m2 ·℃ is three times that of a typical shell and tube heat exchanger.

Unique automatic descaling function

During operation, the spiral shapeFloating coilFrequent vibration and free expansion and contraction with water temperature can cause scale that may form on the outside of the coil to automatically fall off, without the need for special descaling measures, interrupting normal water use and ensuring optimal thermal performance of the equipment.

Product Types

SFP Horizontal Floating Coil Seriesheat exchangerSuitable for steam as a heat source, it is divided into three types according to its usage function: R (hot water type), N (heating type), and K (air conditioning type). Among them, R (hot water type) has 7 specifications according to heat exchange area from 3.41m2 to 14.94m2, and N and K types have 12 specifications according to heat exchange area from 3.41m2 to 39.40m2. The LFP horizontal floating coil series heat exchanger is suitable for high-temperature softened water as a heat source, and there are also three models: R, N, and K. Among them, R ranges from 4.73m2 to

There are 6 specifications for 16.60m2, with heating and air conditioning types to be replacedThe thermal area ranges from 4.73m2 to

39.40m2 has 10 specifications.
