Fluid Coils

Fluid Coils

Heatcraft® Fluid Heating and Cooling coils are typically used to heat or cool air within a condition space. They are components of a large air handling system or unit and commonly labeled as an Air Handling Unit (AHU). Heating coils typically have one to four rows of copper tubes and cooling coils – sometimes up to 12 rows or more, depending on the specific requirements for that application. Heatcraft® heat transfer products include a large variety of drainable circuiting options, making these coils a good choice for most HVAC/R heat transfer applications. They can be made for use with water, glycols, brines, thermal oils, or ammonia-based fluid systems.

Air Handling Unit (AHU) coils can be designed and provided for any customer’s specific need. Selections and calculations are easily done using state-of-the art and user-friendly software tools.

When recommending a coil design, we take many factors into consideration. We will work with you to identify the material combination that is best for your application’s environment and atmospheric conditions into which the coil will be placed. We’ll also recommend a frame design according to the installation type, the maximum fin area, and required fin protection.
