Coil Tubing Heat Exchanger

Coil tube heat exchanger, also known as coil-type exchanger or coil-type heater, is a type of shell-and-tube heat exchanger. Its core structure includes key components such as internal heat exchange tubes, heat exchanger tube walls, and upper/lower ports. GNEE is a professional manufacturer of heat exchangers, equipped with its own production plant and capable of accepting exclusive customization services.

As an energy-saving device, the core function of a coil tube heat exchanger is to effectively transfer part of the heat from the hot fluid to the cold fluid, thus achieving heat exchange between media of different temperatures. It plays an indispensable role in many fields.

Coil-type heat exchangers are widely used in various places, including hotels, restaurants, government agencies, factories, schools, hospitals, swimming pools, etc. They demonstrate excellent performance in hot water supply, heating, and air conditioning systems.

• High-efficiency heat transfer: The coil structure increases the heat exchange area, and the spiral or serpentine design causes the fluid to form turbulence during flow, breaking the boundary layer and improving the heat transfer coefficient. Compared with traditional straight-tube heat exchangers, coil heat exchangers have higher heat transfer efficiency and faster heat exchange speed.
• Compact structure: Coil heat exchangers are small in size and occupy less floor space, making them particularly suitable for space-constrained places such as ships, mobile equipment, or small industrial installations. Their compact design facilitates installation and maintenance.

• Strong corrosion resistance: Coils are typically made of corrosion-resistant materials such as stainless steel and red copper, enabling them to adapt to various complex working conditions, including heat exchange of acidic and alkaline fluids, and extending the service life of the equipment.
• Low maintenance cost: The compact structural design of coil heat exchangers makes them less prone to dust accumulation and scaling, reducing the frequency of cleaning and maintenance. Some coil heat exchangers also have an automatic descaling function, further lowering maintenance costs.
• High adaptability: Coil heat exchangers can be customized according to different process requirements, including the selection of coil diameter, length, number of layers, and materials, adapting to high-temperature and high-pressure or low-temperature and low-pressure working conditions.
