380V 5KW pipeline heater for heating liquids

Circulation Heaters, also known as pipeline heaters, have uses in many applications. They can use steel, stainless steel, or titanium depending on the application. 

Lube oil and waste oil applications often use steel for circulation heaters. This is because it is fairly inexpensive compared to stainless steel counterpart. 

Water circulation heaters use stainless steel because of its anti-corrosive qualities. 

In both applications, a pump flows the liquid, such as water or glycerol, through a closed pipe circuit. The liquid is reheated as it flows through the circulation heater. A major consideration for this application is viscosity. Electric circulation heaters generate heat, making the medium less viscous. The less viscous the fluid, the easier it is to pump through a circuit of pipes.

Working Principle:

Circulation heaters, also referred to as pipeline heaters, operate based on the principle of electric resistance heating. They consist of a heating element (often made from steel, stainless steel, or titanium depending on the application) that heats the fluid as it flows through a closed pipe circuit. A pump circulates the liquid through the heater, ensuring uniform heating. Electric circulation heaters are designed to efficiently transfer heat energy to the fluid, thereby reducing its viscosity and making it easier to pump through the system.

Materials:

The choice of materials for circulation heaters depends on the specific application requirements:

- Steel: Commonly used in applications such as lube oil and waste oil heating due to its cost-effectiveness and adequate heat transfer properties.

- Stainless Steel: Preferred for water circulation heaters and applications where corrosion resistance is crucial. Stainless steel ensures longevity and maintains the purity of the heated fluid.

- Titanium: Utilized in highly corrosive environments or where there are stringent purity requirements. Titanium offers excellent corrosion resistance and is suitable for heating aggressive fluids or chemicals.

Control and Operation:

Modern circulation heaters are equipped with advanced control systems to maintain precise temperature control and ensure efficient operation. Temperature sensors continuously monitor the fluid temperature, allowing the control system to adjust heating output as needed. Control panels provide operators with intuitive interfaces to set temperature parameters, monitor system status, and adjust operational settings. Safety features such as over-temperature protection and fault diagnostics enhance reliability and prevent operational disruptions.

Applications:

Circulation heaters are versatile and find applications across various industries:

- Oil and Gas: Used for heating lube oil, hydraulic oil, and fuel oils in refineries and offshore platforms.

- Chemical Industry: Employed to heat corrosive chemicals and process fluids in chemical plants.

- Water and Wastewater Treatment: Utilized for heating water in industrial processes and heating glycerol in biodiesel production.

- Food and Beverage: Applied in food processing for heating oils and viscous fluids.

- Power Generation: Used for preheating feedwater and other fluids in power plants to improve efficiency.

Conclusion:

Circulation heaters are essential in industrial processes where precise and efficient fluid heating is required. Their ability to reduce fluid viscosity through controlled heating makes them invaluable for optimizing process performance and energy efficiency. With customizable designs and robust materials, circulation heaters offer reliable operation across a wide range of applications, contributing to enhanced productivity and operational sustainability in various industries.
