SFP/LFP series floating coil heat exchanger for heating

SFP/LFP series floating coil heat exchanger for heating

1. Overview:

The heat exchange tube bundle of the floating coil type semi instant water heater adopts a spiral floating coil, which has the characteristics of instant heating capability and ensures stable and safe water temperature control. It is easy to assemble, avoids complex installation, and occupies a small space for the equipment.

2. Performance characteristics:

2.1 Efficient and energy-saving

During the heating process of a floating coil heat exchanger, the centrifugal force generated by the heat medium flowing inside its heat exchange tubes causes high-frequency vibration in the coil, which expands and contracts freely with changes in water temperature, causing disturbance to the heated water medium, disrupting laminar heat transfer, significantly improving heat transfer efficiency, and reducing shell heat loss.

2.2 Unique automatic descaling function

During the heating operation of a floating coil heat exchanger, the frequent vibration of its spiral floating coil and its free expansion and contraction with changes in water temperature make it difficult for scale to adhere to the outside of the coil. At the same time, the thermal shock method is still used to completely eliminate a small portion of the possible attachments, so there is no need to implement specialized descaling measures and corresponding descaling devices, ensuring its relative heat transfer efficiency in the long run. Even if the scale formed on the outside of the coil will automatically fall off and deposit at the bottom of the heat exchanger, regular drainage can be carried out according to the water quality.

2.3 Reasonable structural design

The internal coils of the floating coil heat exchanger are separated, making equipment maintenance convenient, occupying a small area, and the layout of the machine room convenient. The device has a compact structure that effectively utilizes space, occupies a small area, and is easy to move and install.

2.4 Advanced Materials

The internal coil of the equipment is made of high-quality copper tube, and the shell can be made of carbon steel lined with copper or stainless steel material to ensure the cleanliness of the water quality of the heated water inside the product.

3. Scope of application:

Widely used in industrial and civil buildings such as hotels, restaurants, schools, hospitals, laundry rooms, factories, etc. for daily life, heating, air conditioning and hot water systems. Heat media are suitable for three different types of heat media: steam, high-temperature water, and low-temperature water, all of which can achieve good results.

main purpose

a、 Air conditioning and heating in high-end hotels, restaurants, government offices, factories, schools, and public places;

b、 Hot water supply for hotels, residential communities, swimming pools and other sports venues;

c、 Process hot water supply for industries such as chemical, refining, and shipbuilding.
