Tank Coils for Heating & Cooling
Enerquip designs and manufactures custom tank coils for heating and cooling in demanding industrial applications. Our coils are used to heat, cool, or maintain temperature inside storage tanks in industries such as asphalt, chemical processing, refining, biofuels, food production, and more.
Built from carbon steel or stainless steel, Enerquip coils feature seamless piping for reliable heat transfer and long service life. Because accessing a full tank for repairs isn’t simple, we engineer every coil for durability and long-term performance.
Tank Coil Design Options
Selecting the right tank coil design and material of construction depends on several factors, including product viscosity, fouling or coking potential, required heat load, ambient conditions, and budget.
Our engineers can review your application and recommend the best configuration for your operation.
Process Fluid Compatibility:
- steam
- thermal fluid (thermal oil)
- hot water
- or cold water
Material of Construction:
- Schedule 40 or 80 carbon steel
- 316L stainless steel
- High alloy materials available upon request
Coil Types:
- Bare pipe tank coils
- Helically wound finned pipe coils
- Longitudinal finned pipe coils
- Spiral bare pipe coils
Optional pipe supports and legs can be included for added strength and stability.
Bare Tank Coil
When to Choose Bare Pipe Tank Coils
Bare pipe coils are often ideal when:
- Heating highly viscous products
- Fouling or buildup is a concern
- Lighter heating duties are required
Stainless steel bare tank coils are commonly used in food, beverage, and sanitary applications.
Finned Tank Coil
When to Choose Finned Tank Coils
Finned tank coils are designed for higher efficiency and greater heat transfer.
Key benefits include:
- Up to 12 times more surface area than bare pipe coils
- Improved heat transfer performance
- Less total pipe required to achieve desired heating
- Potential savings in installation time and cost
Finned coils are especially effective for larger heat loads and higher-demand applications.
When to Choose Helically Wound vs. Longitudinal Finned Coils
Finned tank coils are available in helically wound or longitudinal designs. Both offer strong heat transfer performance. The key difference is installation orientation, which is influenced by product behavior, flow patterns, and coking potential.
- Helically Wound Coils: Best suited for horizontal installations.
- Longitudinal Finned Coils: Preferred for vertical installations.
If your product has unique flow characteristics or fouling concerns, our team can help determine the most efficient and reliable configuration.
What’s the Optimal Layout for Tank Coils?
Tank coils can be installed in several layouts inside a storage tank, depending on the heating or cooling requirements and tank design. A star pattern layout is often recommended for efficient heat distribution, but the ideal configuration depends on factors such as tank diameter, ambient temperature, heat load, and material of construction.
Tank heating coils are manufactured in banks that sit on the floor of the tank. These coil banks may be arranged in parallel runs, circular patterns, or star configurations to distribute heat evenly across the tank bottom.
An effective layout maximizes contact with the product while allowing good circulation around the coils for efficient heat transfer.
Not sure which layout would be best for your operation? Enerquip engineers can help. We’ll evaluate your tank size, heating medium, and process conditions to recommend the best configuration for reliable, efficient tank heating.
