Coils can be used and mounted in various ways. Proper fit, system requirements, and ductwork determine the case type and configuration needed. Case types can include slip and drive, inverted, stackable, flanged, pitched, collared end plates, and end plates. Large coils that were originally installed as a commercial building was constructed around them can be engineered into two smaller coils designed to re-install into the same space envelope and with the same (or better) performance.
Coil coatings can protect coils from corroding in harsh environments. American Coil is the exclusive home of the the AmeriCoat coil coating system. A unique preparation and epoxy-based protective coating is specifically formulated to increase coil durability and promote heat transfer. AmeriCoat also helps minimize cleaning and maintenance, extending the lifespan of the coated coil.
Coil ratings are assessment of performance to be specified on Water, DX, Steam and Condenser coils. The physical characteristics of the coil (number of rows, fins-per-inch, number of feeds, ect…) will determine the expected performance. This analysis can also be reverse engineered, so if the customer has a specific output performance in mind, our engineers can help build a coil to accomplish those goals.
A modern coil selector is generally a computer based application that can determine the rated capacities of the coil and (if the user desires) automatically optimize the number of rows, FPI (fins per inch), and circuiting feeds based on your performance requirements. Coil selection can be performed on Condenser, Water, DX, Booster Coils, Steam coils and any coil that a given manufacturer is able to construct.
Coil Circuiting Style / Types
Coil circuiting is available in almost any configuration, including: Standard, Row Split, Face Split, and Interlaced. Coil styles refer to the circuiting arrangement on a DX coil.
A heat exchanger is a device, usually a coil, that is used to transfer heat from one medium to another. If your system has fluids that need to transfer heat, a heat exchanger completes the transfer without the fluids (or gases) coming in direct contact with each other.
AmeriCoat is a specially formulated coil coating system created by American Coil. It’s an epoxy-based, protective coating that is coupled with a unique, multi-step preparation and application process. AmeriCoat will actively repel water and keep coated coils clean for over 10,000 hours, even in caustic environments.
Tube fatigue refers to cracking or defects in the structure of the tube caused by a lack of tube support or over pressurization. It also is used to convey the absence of tube casing in contact in a condenser.
Heat Transfer Degradation
Heat transfer degradation is the amount of heat (transfer efficiency) lost over the many years of operation of a unit. Many coil coatings that protect against rust and corrosion cause a large amount of heat to be lost during normal system operations. American Coil protective coating results in less than 1% loss during heat transfer.
OEM refers to the Original Equipment Manufacturer—the original company that makes and sells a specific product; such as Trane, Carrier Lennox, McQuay, Liebert and many others.
Tube Wall Thickness
The tube wall thickness is the measurement of the dimensions of the wall of a coil’s tube. This measurement affects the size of the tube’s inside diameter. Often, two tubes have the same total diameter, but since one has larger tube wall thickness, its internal diameter is smaller. Wall thicknesses are based on U.S. industry standards and sometimes regulations.
