Refrigerator Condenser & Evaporator Coil Manufacturing for OEM Appliance Brands

Domi manufactures custom wire tube condensers, roll bond evaporators, fin-type coils and Bundy tube assemblies for refrigerator and freezer OEM programs. Send your drawing, refrigerant, capacity target and order volume for engineering review.

Are Coil Supply Risks Slowing Your Refrigerator Program?

OEM appliance teams need coil suppliers that can support refrigerant transitions, model-specific geometry, sample validation and repeatable production quality.

Energy Efficiency & Low-GWP Compliance

R290 and R600a platforms require carefully controlled internal volume, tube routing and heat-transfer performance to meet appliance efficiency and safety targets.

Prototype and Launch Delays

Slow drawing review and sample fabrication can delay tooling approval, compliance testing and new-model launch schedules.

Custom Geometry and MOQ Constraints

New appliance platforms often need custom dimensions and connection geometry before mass-production quantities are confirmed.

Batch Consistency and Leak Risk

Inconsistent welding, leakage or dimensional variation can create assembly-line disruption and field reliability problems.

Engineered for Low-Charge Performance, Fast Validation and Stable Production

Low-Charge Coil Design

Coil geometry can be reviewed for R290, R600a and other appliance refrigerants, including tube routing, internal volume and installation constraints.

Final refrigerant charge and performance targets must be confirmed against the appliance system and applicable safety requirements.

Rapid Prototype Development

Drawing review and sample fabrication support help appliance teams validate fit, connection positions and thermal performance before volume production.

Sample timing depends on coil type, tooling status and confirmed technical information.

100% Leak and Dimensional Inspection

Production control can include leak testing, dimensional inspection and order-lot traceability according to the agreed project specification.

Inspection method and acceptance criteria should be confirmed during quotation and sample approval.

Large-Scale Integration: 500+ units per month with capacity and scheduling confirmed per project.

OEM Evaporator Redesign Project

Challenge

An appliance OEM needed to transition a refrigerator platform from R134a to R600a while keeping the cabinet envelope and launch schedule under control.

Engineering Response

The refrigerant change required a review of evaporator circuit geometry, internal volume, connection positions and system-level safety requirements.

Project Outcome

Domi reviewed the duty conditions, supported circuit and roll bond channel optimization, and prepared samples for dimensional and system validation.

The approved design moved to production after sample testing. Final performance, certification and field results remain subject to the customer appliance system and verified project data.
