Applications

Coilmaster fluid coils are designed for air cooling or heating applications using chilled water, hot water, or brine (e.g., ethylene or propylene glycol mixtures). Counter-flow fluid circuits are designed specifically for the intended application to optimize heat transfer while minimizing fluid pressure drops. Connections are sized to match designed flow rates or existing field locations, and every coil is custom circuited to allow for complete drainage with removal of the drain plug. Connection orientations can also be tailored to match installation requirements.

Fluid coils are used in a wide range of heating and cooling applications where efficient heat transfer and reliable temperature control are required. Common applications include hydronic heating systems, chilled water coils, industrial process cooling systems, and data center environments. Whether used to condition occupied spaces, support manufacturing processes, or protect critical equipment, fluid coils play an important role in overall system performance.

Coilmaster designs and manufactures fluid coils for both OEM equipment manufacturers and replacement applications. From standard HVAC equipment to custom industrial fluid coil designs, our engineering team develops solutions that meet specific performance requirements. With U.S.-based manufacturing, fast lead times, and experienced application support, Coilmaster provides dependable coil solutions for a wide range of operating conditions.

Optimized Fluid Coil Performance for Demanding Applications

Fluid coil design directly affects heat transfer efficiency, pressure drop, and overall system performance. Proper coil selection helps maximize thermal performance while maintaining acceptable airflow and fluid flow characteristics. Design factors such as tube spacing, fin configuration, and circuiting all influence operating efficiency and long-term reliability.

Coilmaster engineers fluid coils using precision tube and fin configurations tailored to application requirements. Optimized fluid distribution promotes consistent performance across the coil surface while helping reduce energy consumption and improve system reliability.

These designs are well-suited for demanding applications such as data centers, industrial facilities, commercial HVAC systems, and process cooling environments where dependable performance is critical.

Custom Fluid Coil Solutions for OEM and Replacement Needs

OEM Applications

Coilmaster fluid coils are designed for use in air handling units, chillers, packaged equipment, and custom HVAC systems. OEM customers rely on Coilmaster for tight manufacturing tolerances, consistent quality, and scalable production capabilities that support both standard and custom equipment designs.

In addition to chilled water coils, Coilmaster manufactures standard steam coils and steam-distributing coils for applications requiring precise temperature control and efficient heat transfer. Our engineering team works closely with manufacturers to support system efficiency goals while meeting evolving performance requirements.

Aftermarket and Replacement Applications

When replacement coils are required, minimizing downtime is often a priority. Coilmaster provides replacement solutions designed to match existing performance requirements and support rapid return to service.

Using EZ-Coil selection software, our team can accurately identify and match existing coil designs. This process helps contractors, facility operators, and service organizations obtain dependable replacement coils with fast turnaround and responsive support.

Capabilities Overview

Coilmaster fluid coils can be customized with a range of performance and installation options designed to improve efficiency, simplify maintenance, and meet specific system requirements.

Vent and Drain connections are supplied on all fluid coils, unless specified otherwise. The standard connection is a ¼” FPT copper bushing located on the face of the headers. We recognize this may not be the optimum location for all coils, so we offer a variety of connections and locations based on overall coil geometry and customer needs. Vent and drain connections can be placed in the top and bottom of the headers, inside or outside the headers, or even in the connections. These optional connection locations facilitate proper venting and draining and, therefore, reduce the installation and maintenance cost over the life of the coil.

Turbulators are available to enhance the overall heat transfer of the coil by inducing more fluid turbulence inside the tubes. These brass, spiral, turbulators are typically applied in low-flow applications, or for heavily-viscous fluids. While initial cost and increased pressure drop are to be considered, they are a cost-effective solution for many applications.

Integral intermediate drain pans are an option for those applications where a single coil is required in lieu of multiple stacked coils. This feature incorporates an intermediate drain pan in the fin pack of the coil, allowing the coil to be installed as a single unit.

In cooling applications it is a common occurrence to have leaving air conditions that approach 100 percent saturation. Under such conditions, water is likely to condense on filters, equipment, or in the duct work, which can lead to premature equipment failure and mold formation issues. To help avoid condensation forming downstream of cooling coils, it is necessary to de-saturate the leaving air.

 

Our SureDri coil can accomplish this in one coil. The SureDri coil consists of two cores: the primary cooling core and a re-heating core. By properly designing the primary core, it is possible to have the leaving fluid temperature sufficiently above the leaving air temperature. This “warmer” fluid is then passed through the re-heat coil positioned on the outlet air side of the primary core, to slightly increase the air temperature. The result is cool air leaving the coil that has a lower relative humidity and is less likely to condense downstream.
