Grid coils facilitate maximum heat transfer for applications in which space is a concern. For applications with lower heat transfer rates, serpentine or U coils may be a better fit. There are a number of factors, such as the tank geometry and size, heat transfer fluid, and the properties of the surrounding fluid, that go into determining serpentine coils for heating tanks steam or coolingCooling Coils
Jun 04, 2004We need to design a heating coil in a tank containing a heavy crude oil, in order to maintain it at 160 - 170 °F. Can anyone provide us the equations for estimating the heat transfer coefficient on the oil side? We intend to use a coil which is to be located at the tank bottom.Energy Consumption of Tanks and Vats Spirax SarcoThe heating of liquids in tanks and vats is an important requirement in process industries. There are many types of tank with different uses. Find out more about the determination of heat requirements, heat transfer and heat loss calculations.Heating & Cooling Immersion Coils Metal Pickling & FinishingAPEX Engineered Products is a leading manufacturer of corrosion resistant heat transfer and process equipment solutions.

SX-2 Serpentine Coils are especially suited for heating/cooling application where a medium amount of heat transfer is required. These coils can be extremely well adapted to odd sized tanks. SX-2 Serpentine Coils are supplied in three standard designs in variable lengths. Other designs are available upon request. SX-2 Serpentine Coil Selection ChartHeating Cooling Coils Lanco Product Categories ArchivesLanco Corporation, often times or currently has in inventory, the following used heating cooling coils used heating coils, used cooling coils for industrial uses, serpentine coils, stainless steel plate coils, used plate coils, used tube coils, used heating and cooling coils made of steel, stainless steel, copper, galvanized steel, titanium, used stainless steel grid coils, used heat transfer serpentine coils for heating tanks steam or coolingHeating with Coils and Jackets Spirax SarcoSteam heating coils should generally have a gradual fall from the inlet to the outlet to ensure that condensate runs toward the outlet and does not collect in the bottom of the coil. Where a lift is unavoidable, it should be designed to include a seal arrangement at the bottom of the lift and a small bore dip pipe, as shown in Figure 2.10.2.
Hy-Way Horizontal tanks feature a high-efficiency, close-wound, serpentine coil for increased oil circulation and better heat transfer. Quarter-inch butt-welded steel plate forms the rugged shell construction of the tank with four inches of fiberglass insulation on the shell to reduce conductive heat Images of Serpentine Coils for Heating Tanks Steam or Cooling imagesJSAheating & cooling coils Heating & Cooling Coils are available in many styles including Grid Coils, Plate Coils, Serpentine Coils, Fluoropolymer Coils and Spaghetti Coils. Space, chemical compatibility and available steam or water pressure are three primary determining factors when selecting a coil.Jacketed Vessels Sigma ThermalAt Sigma Thermal, we craft custom thermal fluid heating systems to outfit tanks, vessels, heated molds, building heaters, autoclaves, reactors, and much more. Using thermal oil, glycol, and water as heat transfer mediums, these systems can be combined with a jacketed vessel for exceptional fluid management solutions.
While heat is transferred by direct radiation only on the inside surface of the helical coil tubes, heat is transferred to the front, sides and back of the serpentine coil. As a result, the serpentine coil design allows for more even heat distribution, less oil degradation, longer tube life and higher operating oil Serpentine Coils Titan Industrial HeatingSerpentine Coils can be a simple U shape, 4 pass, 6 pass or if need be 8 Pass Coil. These come in 316 or Titanium. They can be made with other materials check with factory on special Applications.Serpentine Coils for Heating Tanks Steam or CoolingSerpentine coil heaters are typically used in chemistries that require very minimal heat recovery time. Serpentine and U coils are used in situations where smaller heat transfer requirements are needed. Steam Coils For Tanks. Grid Coils are used for large heating up or cooling down of larger process tanks. The steam coil design has the serpentine coils for heating tanks steam or cooling
In sizing heat transfer coils it is important to select the configuration with the smallest width and longest length compatible with tank size to provide the best heat distribution. Using data found in Table V, you can determine that a coil width of 18.5 inches and a length of Sizing Heating and Cooling Coils Products FinishingA Few Simple EquationsOther Factors Affecting QDetermining The U FactorCompleting The Basic EquationSurface Area vs. Heat Transfer Device ConfigurationThere Are Many Coil Styles AvailableThe Right Calculations Save Time and MoneyEquation No. 1 combines all the factors that determine the surface area of the heat transfer device.A = Q/UT. A = area; Q = total heat input required; U = number describing the heat transfer coefficient or degree of influence of materials, agitation, viscosity and other system details. The U-factor is usually developed from past experience.T is a difference in temperature.

Finned Coils. Tank Heating Coils. We can also fabricate with fintubes having the orientation of the fin in the direction of the convection currents in serpentine coils for heating tanks steam or coolingThermal Fluid Heating and Serpentine Coils
Heating coils may be used with hot water or steam as the heat transfer media whilst frost pre-heaters usually have electric heating elements. Cooling coils are classified as being either of the water or the direct expansion type depending on the media flowing through the tubes. A heating coil is shown below.
