Where this aluminum tube evaporator fits
A fin-type evaporator uses an extended fin surface around tubing to exchange heat with the air stream in a cooling system. The exact coil arrangement depends on the cabinet or enclosure, target air temperature, refrigerant circuit, airflow, defrost method, and available installation space. These design inputs must be confirmed for the project; they are not fixed by the product title.

Aluminum tube and fin-pack construction
The product name and current Domi technical reference confirm aluminum-tube construction with an aluminum fin pack and side-plate components. The assembly may also include connections, supports, and mounting details matched to the cabinet. Tube alloy, joining method, fin pattern, coating, and corrosion requirements should be confirmed from the drawing or quotation rather than assumed from a generic evaporator specification.
Tube-side details to confirm
Provide the tube outside diameter and wall requirement, bend geometry, circuiting, inlet and outlet position, connection type, joining process, refrigerant or other working medium, operating pressure, and test pressure. A replacement inquiry should include photographs of both connection ends and any existing markings.
Air-side and support details to confirm
Provide the face width and height, coil depth, row count, fin pitch, airflow direction, fan position, mounting brackets, drain arrangement, service clearance, and any protective or corrosion-resistant finish requirement. If the evaporator operates below freezing, include the defrost and condensate-management requirements in the drawing package.
Published technical reference data
The current Domi listing contains a technical reference table. The values below are useful starting points for a quotation, but they should be checked against the approved revision because the final coil is drawing- and application-dependent.
| Reference item | Current listing information | Buyer confirmation |
|---|---|---|
| Aluminum tube | Ø8.0 × 0.7–1.0 mm | Confirm alloy, tolerance, tube condition, bend geometry, and joining method. |
| Bare aluminum fin | Thickness T = 0.15–0.25 mm | Confirm fin pattern, pitch, alloy, surface treatment, and air-side cleanliness. |
| Side plate | Aluminum plate T = 0.8–1.5 mm | Confirm support shape, mounting holes, drain details, and cabinet clearance. |
| Application | Refrigerator and freezer | Confirm cabinet type, air temperature, airflow, defrost method, and service space. |
| Tube layout reference | Diagonal-inserting: 50 × 19.05 × N or 60 × 19.05 × N, N ≥ 4; pull-expanding: 60 × 28 or 52 × 28; press-expanding: 50.8 × 203.2. | Confirm the applicable layout, unit convention, row count, pitch, and drawing revision. |
| Manufacturing reference | Tube bending, fin punching, tube expanding, degreasing, welding and assembling, leakage test, drying, inspection, and packing. | Confirm the actual process route, joining method, inspection plan, and release records. |
The listing also shows reference cleanliness limits for internal volume bands: residual moisture of ≤10, ≤20, ≤25, and ≤30 mg, residual impurity of ≤100 mg/100 cm³, and a biggest single impurity of ≤2 mg. The printed bands include both 101–200 cm³ and 101–400 cm³, so the intended banding, test method, and acceptance basis should be confirmed before purchase-order release.
Published information versus project confirmation
This separation helps procurement teams use the page without treating a catalog reference as a certified rating. Domi should confirm the project-specific value in the quotation, drawing, inspection plan, or test report.

How to specify an aluminum fin evaporator coil
When comparing an aluminum tube evaporator supplier, use a complete input package. The following checklist helps the supplier quote the correct construction instead of a visually similar but incompatible coil.
- Define the system position: confirm that the component is an evaporator and identify the refrigerator, freezer, cabinet, or cooling system in which it will operate.
- State the operating conditions: provide refrigerant or medium, evaporating temperature, return-air condition, target air temperature, ambient condition, superheat, and pressure requirements.
- Describe the air side: provide airflow, fan position, face velocity if available, frost or defrost condition, drain direction, and service access.
- Provide dimensional control points: include width, height, depth, rows, fin pitch, tube pitch, connection location, mounting points, and allowable tolerances.
- Confirm the tube circuit: specify inlet/outlet size, circuiting, header or connection arrangement, joining method, and any existing part number.
- Confirm material and finish: state the aluminum alloy if required, fin material, coating, corrosion exposure, cleanliness, and packaging protection.
- Set the inspection basis: identify leak-test method, test pressure, cleanliness limits, dimensional checkpoints, visual requirements, and the documents needed for release.
Drawing and sample-based customization
The current product reference states that the evaporator can be designed and produced according to drawings, samples, and client requirements. A drawing is the preferred reference because it captures the coil envelope, connections, mounting, circuiting, and tolerances in one document.
What to send for a replacement evaporator
- Photos of the complete coil and close-ups of the inlet and outlet.
- Overall width, height, depth, and mounting dimensions.
- Tube diameter if known, fin pitch, row count, and any label or model number.
- Refrigerant, operating temperature, defrost method, and the original equipment type.
- Required quantity, destination, packaging constraints, and target approval date.
What to send for a new OEM project
- Cabinet or enclosure drawing with the available coil space.
- Thermal duty and the test conditions used by the system designer.
- Airflow, fan position, drain arrangement, and defrost requirements.
- Connection and circuiting requirements with the desired inspection records.
- Required aluminum material, surface treatment, packaging, and repeat-order revision control.
Manufacturing and quality checkpoints
The current technical reference lists tube bending, fin punching, tube expanding, degreasing, welding and assembly, leakage testing, drying, inspection, and packing. For a project-specific order, request the applicable process route, joining method, test pressure, acceptance limit, cleanliness basis, inspection points, and record format before production approval.
For repeat orders, keep one approved drawing and acceptance sheet as the reference revision. Record any change to tube, fin, circuiting, connection, coating, packing, or inspection criteria so replacement coils remain traceable across batches.
Questions for quotation review
- Which dimensions are critical to cabinet fit?
- Which aluminum alloy, tube wall, fin thickness, and pitch must appear on the specification?
- Which operating and test pressure must appear on the drawing?
- What leakage and cleanliness records are required for incoming inspection?
- Does the fin pack need a coating or special corrosion protection?
- How should the coil, connections, and fins be protected during shipment?
Aluminum tube versus copper tube evaporator
Aluminum tube is one construction choice. The correct comparison depends on the system position, operating conditions, joining requirements, and approved material specification—not on tube material alone. Review Domi’s copper-tube fin type evaporator when the project drawing requires copper construction, and keep the tube, fin, connection, pressure, and compatibility requirements consistent across the comparison.
For condenser-side alternatives, review the industrial refrigeration condenser, single-layer wire tube condenser, multilayer wire tube condenser, or tube-on-plate condenser. For wider project context, see commercial cooling coils, custom coil fabrication, engineering capabilities, manufacturing process, testing lab, and quality and certification information.
