Custom Evaporator Coils.
Custom DX evaporator coils for commercial equipment, replacement, and retrofit. Choose the measurement pathway or submit an existing drawing through the drawings pathway in Coil Brief.
An evaporator coil absorbs heat from the air as refrigerant evaporates inside its tubes. Air passes across the fins and leaves cooler, while the refrigerant carries the absorbed heat back through the system. When the coil surface is below the air’s dew point, moisture also condenses on the coil.
In a direct-expansion, or DX, coil, the distributor and feeder tubes divide incoming refrigerant among the circuits. The suction connection collects refrigerant leaving the coil. Circuiting, refrigerant, airflow, and operating conditions all influence the design; the illustration shows one possible arrangement.
//Coil selection
What matters when selecting a DX evaporator coil?
The right evaporator coil depends on cooling and moisture removal, airflow, refrigerant, and installation requirements.
What to consider
Why it matters
Cooling and humidity
Cooling requirement and moisture removal
Airflow and pressure drop
Airflow, fan capability, rows, and fin spacing
Refrigerant and circuiting
System refrigerant, circuit arrangement, and distributor details
Materials and environment
Material compatibility, operating environment, and coil protection
Fit and installation access
Casing dimensions, connections, orientation, and removal space
Replacing an existing coil? Start with its measurements or drawing.
Operating data is not required to begin a measurement-based replacement request. Refrigerant and circuit details still need to be confirmed.
Relative material cost. Final pricing depends on coil specifications.
Casing
The formed frame supports and protects the coil. Galvanized steel and stainless steel casing options are reviewed against the application and approved drawing.
Material combinations, circuiting, and final specifications are reviewed in your Coil Brief.
Refrigerants for commercial HVAC
Your system’s refrigerant helps determine the coil’s materials, pressure requirements, and design.
R-410A
Used in many existing HVAC systems.
R-32
Used in newer HVAC equipment.
R-454B
Used in newer HVAC equipment.
Examples shown. Refrigerants vary by equipment and application.
Specify your system’s refrigerant in your Coil Brief. Each coil is designed for its stated refrigerant and operating conditions.
Replacement and order details
OEM replacements
Discontinued or unknown model? Start with measurements or a drawing.
Independent aftermarket replacements. Rowform is not affiliated with or endorsed by these brands.
If the original evaporator coil is discontinued or no longer available, you can still submit a replacement request. Rowform reviews the existing coil details and application to determine whether a custom replacement can be supplied.
Choose the measurement pathway to provide the coil measurements and refrigerant/circuit details, or choose the drawings pathway to order from an existing drawing. When using measurements, the equipment brand and model, nameplate photos, connection photos, and supporting drawings are optional. A brand or model name alone does not confirm replacement fit.
Rowform supplies independent aftermarket replacements and is not affiliated with or endorsed by these equipment brands.
Coil dimensions
Enter the overall and casing dimensions, fin dimensions, and coil depth requested in the measurement pathway. Coil Brief guides you through each measurement.
Connections and distributor
Enter the connection diameters, locations, and orientation requested in Coil Brief. Photos of the connections or distributor are optional supporting information. Drawings are not required when using the measurement pathway.
Tube, fin, and circuit details
Enter the materials, rows, fins per inch, and refrigerant circuit details requested in Coil Brief. Follow the guidance for any detail you do not know.
Refrigerant details
For a measurement-based replacement, provide the existing coil measurements and refrigerant/circuit details requested in Coil Brief. Airflow, operating conditions, and performance specifications are not required for this pathway.
For requests based on operating requirements, email [email protected].
Coil protection
Nano Coating, E-Coating, and optional hydrophilic fin treatment.
Select No Coating, Nano Coating, or E-Coating in the Coil Protection step of Coil Brief. Use Help me choose to compare Nano Coating and E-Coating for your coil’s environment.
Nano Coating is a clear coating; E-Coating provides an epoxy barrier. Hydrophilic fin treatment is a separate optional add-on that helps water spread and drain from the fins. Added treatments are priced in your quote.
Your quote separates manufacturing and transit estimates.
Your quote will include estimated manufacturing and delivery times for your coils. The estimates depend on the coil specifications, order quantity, and delivery arrangements.
Review the estimated times with your quote. You will also review and approve the engineering drawing before production.
Expedited production and shipping are not currently available.
12-month limited warranty
Coverage begins at documented delivery.
Coverage starts at documented delivery and covers qualifying manufacturing and material defects. Registration is not required.
Freezing damage and corrosion caused by unsuitable fluids, chemicals, or environmental exposure are excluded. Review the full coverage, exclusions, and remedies before ordering.
Check the proposed dimensions, connection locations, materials, circuiting, distributor arrangement, and any selected coating on the engineering drawing before approving it. Contact Rowform about discrepancies before approval.
Submitting a Coil Brief does not place an order or require payment. Coil Record keeps your project documents and order updates together.
Yes. Equipment model and part numbers are optional. Provide the required coil details through measurements or drawings and specifications. Rowform reviews your submission and follows up if more information is needed.
Identify the refrigerant used by the existing system and provide the refrigerant/circuit details requested in Coil Brief. Airflow, operating conditions, and performance specifications are not required for the measurement pathway. If your request is based on operating requirements, send those requirements by email to [email protected]. Changing refrigerants requires a separate system review.
Enter the circuit details requested in Coil Brief, including the number of refrigerant circuits if known. Equipment information, photographs of the connections or distributor, and supporting drawings are optional when using the measurement pathway. You do not need to supply all of these files. If you prefer to order from a drawing, choose the separate drawings pathway. Do not guess at hidden circuiting.
Yes. Use the measurement pathway to provide the coil measurements and refrigerant/circuit details, or use the drawings pathway to submit an existing drawing. Equipment brand and model information, nameplate photos, connection photos, and supporting drawings are optional in the measurement pathway. Rowform reviews the submitted coil details to determine whether a custom replacement can be supplied.
Enter the casing dimensions, connection dimensions, and orientation requested in the measurement pathway, or provide them through the drawings pathway. Rowform reviews these with the construction and refrigerant details. Check the proposed dimensions and connections on the engineering drawing before approving it.
Yes. Choose the drawings or specifications route in Coil Brief and supply the documents that describe the coil you need. Rowform reviews the submitted information for completeness.
Your quote will include estimated manufacturing and delivery times. We aim to manufacture your coils in less than three weeks. Timing varies by coil specifications and order size, and production begins after the required approvals and payment are complete. This is a manufacturing target, not a guaranteed delivery time. Expedited production and shipping are not currently available.
