DX Evaporator Coils
Direct Expansion Evaporator Coils for Precision Cooling
Direct Expansion (DX) Evaporator Coils are an efficient HVAC/R cooling solution, because they cool air directly using refrigerant. Precision Coils manufactures direct expansion coils made with copper sweat connections, and customers can choose between standard or hot gas distributor options.
Choosing the Right DX Evaporator Coil
When ordering new DX Evaporator Coils, let Precision Coils’ expert team guide you through the selection process. Certain specifications are critical for DX coils to operate properly, and the experience of our staff ensures your coils will function with maximum efficiency. These are the factors to consider when selecting DX coils:
- Cooling Capacity: The cooling capacity of the DX coil must match the cooling load of the entire HVAC/R system for the coil to operate efficiently.
- Refrigerant Type: Select a DX coil compatible with a refrigerant that meets your HVAC/R system’s design requirements and local environmental regulations.
- Fin and Tube Materials: Standard DX coils are constructed with copper tubes and aluminum fins, but for applications in corrosive environments, all-copper coils or an epoxy coating may be required.
- Circuiting and Rows: Our DX coils are constructed with the proper number of rows and correct circuiting for optimum refrigerant distribution and cooling performance.
- Airflow Configuration: DX evaporator coils can be built to accommodate horizontal, vertical or universal airflow, and our staff ensure the correct coil design is chosen for the layout of your HVAC/R equipment.

Applications of Direct Expansion Coils
Given their smaller footprint compared to other HVAC/R systems, DX coil systems are used to cool smaller spaces. Some of the applications for DX coils include:
- Residential HVAC Systems
- Air Handling Units (AHU) for Small Commercial Spaces
- Refrigeration Cases and Coolers
- Variable Refrigerant Flow HVAC Systems
- Split HVAC systems
- Rooftop Packaged Units
Benefits of DX Evaporator Coils
- Compact Design: DX coil HVAC/R systems occupy less space than chilled water systems, making DX systems ideal for buildings with space constraints.
- Energy Efficiency: In HVAC/R applications with variable cooling loads, DX evaporator coils maintain efficient operation.
- Precise Cooling: When cooling needs change rapidly, DX coils quickly adjust to maintain consistent temperature and humidity.
- Cost-Effective Installation: DX coil HVAC/R systems eliminate the need for chilled water piping and a central chiller plant, lowering installation costs.
