Heating Coil Calculator - Welcome to MBA's Exclusive Coil Calculator... now finding the right coil for your application is easy.
This calculator will help you find the size of coil you will need as well as the material best suited for your coil (see material selection chart and disclaimer. This unique calculator can be used for heating-as well as for cooling applications. After finding the coil that fits your tank, request a quote from MBA with a touch of a button!Here are some tips on entering information into the calculator:
Tips On Entering Information Into The Coil CalculatorTemperatures
- Starting temp. of tank = the temperature of fluid in your tank before it is heated.
- Operating temp. of tank = the desired temperature of your tank for regular operation. Consult MBA if your tank operates above 180°F or if the difference between your operating temperature and the temperature of your supply fluid or steam in your coil will be less than 15°F.
- Coil source temp. = the temperature of fluid or steam that will be used in the coil to heat the tank.If steam is used in the coil and you know the pressure of steam in PSI, you may select the steam PSI instead of entering a temperature. In that case, leave the source temperature box empty.
Heat-up time - Number or hours it takes to get your tank from the Starting temperature to the Operating temperature. You may enter fractions of an hour also (example: 1.5 hours). The size of a coil is often determined by the time required to raise the solution to operating temperature. In general, the more time you allow, the smaller the coil. Short heat-up times require large coils.
Saturated steam in PSI - The temperature of saturated steam is proportional to it's pressure in PSI. The coil calculator automatically converts the steam PSI to the appropriate temperature value. If you select a steam PSI value you must leave the source temperature box empty. Here's a guide for relating steam pressure in PSI to temperature:
Air ventilation over tank - As you increase the operating temperature of the tank, surface heat losses become significant, especially when there is air passing over the tank surface. The Coil calculator compensates for this surface loss for temperatures of 160F and above. If you don't know the air velocity over your tank, select "1 foot/second".
Selecting tank solution - Your coil material is determined by the type of solution to which your coil will be exposed. It is extremely important to choose your tank solution properly. If your tank solution is not on the list, please select "Other" from the list. If you are using a proprietary solution in your tank, please consult your chemical supplier for proper choice of coil material.
Material Disclaimer - Material suggested on this web site provide general guidelines only. In view of the ever increasing amounts of proprietary chemical solutions being offered by chemical suppliers, we suggest that you contact your chemical supplier and
follow their recommendation in selecting the most suitable material for your
Tank agitation - Agitating the solution in your tank improves heat transfer properties and might lead to smaller coils. Agitation also enhances the corrosion resistance of metal. For special applications, MBA offers SX-2 Coils with built-in Airspargers.
