Custom Evaporator Coil Manufacturer | Build from Drawing or Old Coil Sample

Many HVAC‑R system builders and maintenance technicians face a common problem: original evaporator coils go damaged or leak, while OEM spare parts are expensive, long‑lead time or completely discontinued. Working with a reliable custom evaporator coil manufacturer that can produce from your drawing or old physical sample becomes a practical solution for both replacement and new‑build projects.

Two Main Ways We Make Your Custom Evaporator Coil

1. Manufacture based on customer technical drawing

Send us dimension drawings, coil layout, tube circuit diagram, connection position, material specification and working parameters. Our team reviews manufacturability, pressure requirement and refrigerant compatibility, then produces strictly following your drawing data.

• Fit for new ODM projects, volume OEM production

• Clear 2D / 3D drawing helps avoid fitting mistakes

• All headers, nozzles, mounting holes, drain pan structure follow your design

2. Replicate from old failed coil sample

If you do not have formal drawings, you can provide the original old evaporator coil. We reverse‑engineer all key parameters: overall size, tube diameter, row count, FPI, fin type, refrigerant circuit path, inlet‑outlet orientation, bracket and drain pan dimension. We produce 1:1 matching replacement coil.

Practical tips for old‑coil sample submission:

• Capture full‑view photos plus close‑ups of connections, bends and mounting brackets

• Record real‑world running condition: refrigerant type, operating pressure, application equipment

• No need to send physical sample in many cases; complete measurement photos + dimension list work for quotation

Customizable Evaporator Coil Options

• Tube material: Copper tube, SS304 / SS316 stainless steel tube, Cu‑Ni copper‑nickel tube for corrosive environment

• Fin: Bare aluminum, hydrophilic coating for condensate drainage, epoxy / phenolic anti‑corrosion coating for coastal salt‑spray sites

• Fin density (FPI): Wider fin spacing for anti‑frost, anti‑dust‑clogging; high FPI for high cooling demand

• Shape: Flat, U‑shape, L‑shape, non‑standard special geometry

• Auxiliary accessories: drain pan, mounting brackets, defrost heater bosses, sensor bosses

• Refrigerant fit: R410A, R134a, R290, CO₂ and other low‑GWP refrigerants

• Pressure test: Each coil goes through air pressure leak test before shipment

Application Equipment for Custom Evaporator Coils

• Air source heat pump DX evaporator coils

• Chiller direct‑expansion evaporator coils

• AHU DX cooling coils

• Dehumidification system evaporator and reheat coils

• Environmental chamber / test chamber cooling coils

• Process cooling & industrial condensing unit evaporators

Our Project Process

1. Customer submit: drawing files OR old‑coil photos + dimension list OR physical sample

2. Engineering review & parameter confirmation

3. Formal quotation

4. Sample trial for mass order if required

5. Production, pressure & leak test, export packing

6. Shipment

Important Reminders

1. Outer dimension alone is not enough for duplication. Tube circuiting, FPI, tube row number directly decide cooling capacity and pressure drop.

2. For coastal, marine or chemical‑polluted locations, inform us working environment so we select proper material and coating to prevent early corrosion failure.

3. Custom evaporator coils support single‑unit replacement as well as bulk OEM orders.

Summary

As a professional custom evaporator coil manufacturer, VRCOOLER accepts projects from customer drawings or reverse‑engineered old coil samples to deliver 1:1 replacement or newly‑designed tube‑fin evaporator coils for HVAC‑R industrial equipment. No need to depend on hard‑to‑get original spare parts.
