Custom Hot Gas Reheat Coils.
Custom hot gas reheat coils for commercial replacement and retrofit requests. Start with measurements of the existing coil or submit an existing drawing through the separate drawings pathway in Coil Brief.
2–3 minutes with measurements ready.
What does a hot gas reheat coil do?
A hot gas reheat coil warms air after a cooling coil has removed moisture. It uses heat from hot refrigerant in the refrigeration circuit to raise the temperature of the cooled air before it is supplied to the space. This helps the system manage humidity without delivering air that is colder than needed.
Moisture is removed at the cooling coil; the reheat coil raises the air temperature without adding moisture. Refrigerant flows inside the reheat tubes while air passes between the fins. The illustration shows one possible construction, with connection and circuit arrangements confirmed for the equipment.
Hot gas reheat replacement coils for your equipment.
Rowform reviews the submitted coil details to determine whether a custom replacement can be supplied. The review includes dimensions, construction, connection layout, and refrigerant/circuit details for the existing reheat coil.
Coil dimensions
Enter the overall, casing, and fin dimensions and coil depth requested in the measurement pathway. Use the measurement guidance or contact Rowform if a detail is unclear.
Connections and orientation
Provide the requested connection diameters, locations, and orientation from the existing coil. Connection photos are optional supporting information; drawings are not required in the measurement pathway.
Tube and fin construction
Enter the requested materials, rows, fins per inch, and tube counts from the existing coil. Check the proposed construction on the engineering drawing before approving it.
Refrigerant and circuits
Provide the system refrigerant and refrigerant circuit details requested in Coil Brief. Airflow, operating temperatures, and performance targets are not required for a measurement-based replacement request.
Choose the measurement pathway or the separate drawings pathway. Equipment brand and model, nameplate photos, connection photos, and supporting drawings are optional in the measurement pathway; you do not need to supply all of them.
Materials and construction
Explore materials for your hot gas reheat coil.
Fin materials
Explore aluminum and copper fin construction.
Aluminum
Relative upfront cost: 1 of 3.
Copper
Relative upfront cost: 2 of 3.
Tube materials
Explore copper and stainless steel tube construction. Final material selection depends on the application.
Copper
Relative upfront cost: 1 of 3.
Stainless steel
Relative upfront cost: 2 of 3.
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.
The illustration shows copper tubes and aluminum fins. Final materials, connections and construction are confirmed through the approved drawing.
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.
OEM and discontinued-model replacements.
You can submit a replacement request even if the original hot gas reheat coil is discontinued or the equipment model is unknown. Use the measurement pathway to document the existing coil, or submit an existing drawing through the drawings pathway.
An equipment brand or model alone does not confirm compatibility. Review the proposed dimensions, connections, construction, and refrigerant/circuit details for the individual replacement.
Rowform supplies independent aftermarket replacements and is not affiliated with or endorsed by these equipment brands. Brand pages do not establish compatibility with every model.
Corrosion protection and 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.
Choose protection in Coil BriefManufacturing and delivery estimates.
Your quote includes estimated manufacturing and transit times based on the reviewed specifications, quantity, and freight service. Transit begins after dispatch and does not include production time.
Estimates are not guaranteed delivery dates. Expedited production and shipping are not currently available.
12-month limited coil warranty.
Coverage starts at documented delivery and covers qualifying manufacturing and material defects. Registration is not required.
Coverage is subject to the Terms of Service. Review the full warranty for exclusions, claim instructions, and remedies before ordering.
Read the limited coil warrantyReview your drawing before production.
Check the proposed dimensions, connection locations, materials, construction, 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.
