Chilled Water Coils
A chilled water coil is a heat exchange component that provides comfort cooling to commercial and industrial buildings across the world. As cold water circulates through the tubes of the coil, the fin surface is cooled; the entering warm air is then tempered as it passes over the fin surface of the water cooling coil. In addition to cooling, chilled water coils are widely used for dehumidification — removing moisture from air streams in demanding environments.
Most chilled water cooling coils operate with an entering air temperature between 75°F and 95°F, with chilled water entering at approximately 45°F. A water chiller coil can range anywhere from 3 to 12 rows deep, while hot water coils are typically 1 or 2 rows.
Tailor-Made to Meet Performance
For these systems to function properly, it is of critical importance to have a chilled water coil that is tailor-made to meet the performance of the air handling unit it serves. Utilizing the most advanced, technologically efficient engineering software, the performance your system requires is met by modifying coil size, circuitry, and materials of construction. Turbo-Spirals are also available, increasing efficiency and ensuring maximum heat transfer.
Coil Replacement Company has mastered the art of building direct replacement chilled water coils for manufacturers including, but not limited to, Aerofin, American Standard, Bohn, Carrier, Daikin, Lennox, Magic Aire, Modine (formerly Heatcraft, Luvata), McQuay, Munters, Trane, Westinghouse, and York. In addition, CRC maintains 100+ years of OEM engineering drawings and proprietary performance heat transfer data. CRC uses this data to properly match the size and performance of your existing chilled water coil; the goal is to make the installation process as easy as possible, meaning the coil fits and the connections are aligned with the existing piping in your facility.
CRC assigns a dedicated engineer to review, visit, measure, or consult (virtually) by analyzing your exact coil requirements. CRC then generates drawings, performance evaluations, and quotations – while taking responsibility for your coil and/or product solution. We deliver unparalleled service, allowing the mechanical contractor and end-customer to focus on their core assets and property management responsibilities.

Frequently Asked Questions About Chilled Water Coils
A chilled water coil is a type of heat exchanger installed within an air handling unit (AHU) or fan coil unit. Cold water from a chiller circulates through the coil's tubes, cooling the fin surface. As warm air passes over the fins, it is cooled and/or dehumidified before being distributed throughout the building.
A chilled water coil (also called a water cooling coil or water chiller coil) is used to cool supply air by absorbing heat from the air stream into cold water. A water cooled condenser coil rejects heat from a refrigerant loop into a condenser water circuit. Both use water as a heat transfer medium, but they serve distinct roles in an HVAC system.
Chilled water coils typically range from 3 to 12 rows deep, depending on the cooling load, entering air conditions, and desired leaving air temperature. CRC's engineers will determine the optimal row depth during the design and quotation process.
Yes. CRC maintains a database of 100+ years of OEM engineering drawings covering manufacturers such as Aerofin, Bohn, Carrier, Daikin, Lennox, McQuay, Trane, York, and many more — enabling precise direct-fit replacements.
There are several ways to extend the lifespan of your chilled water cooling coil. From a construction standpoint, specifying stainless steel casings, thicker tube walls, and thicker fins will increase durability and long-term performance. CRC also offers a full range of protective coatings - including ElectroFin® E-Coat, Endura®, Infinigard, phenolic, and UV Topcoat - to guard against corrosive environments such as coastal areas, pool facilities, industrial plants, and more. Contact CRC to discuss the right combination of materials and coatings for your specific application.
