SAMPLE APPROVAL RISK
Testing Data Helps Buyers Approve Samples with Confidence
For custom heat exchangers and refrigeration coils, buyers need more than appearance inspection. They need validation data that supports heat transfer performance, airflow behavior, corrosion resistance, leakage control, pressure safety and long-term application reliability.
Unverified Thermal Performance
Problem: A coil may look correct but still fail to meet cooling or heating capacity targets.
Solution: Thermal performance testing and engineering review can help buyers compare design expectations with measured or project-specific validation data.
Airflow and Pressure Drop Uncertainty
Problem: Uneven airflow or excessive pressure drop can reduce heat exchanger performance in HVAC and refrigeration systems.
Solution: Wind tunnel testing or airflow analysis can help review air-side performance, flow distribution and coil resistance.
Corrosion Risk in Harsh Environments
Problem: Commercial kitchens, coastal areas, industrial environments and humid cold rooms may accelerate corrosion.
Solution: Salt spray testing and material review can support coating or material selection for corrosion-sensitive applications.
Pressure and Safety Concerns
Problem: Heat exchangers used in refrigeration, CO2, industrial cooling or liquid cooling projects may face pressure-related risks.
Solution: Pressure testing, burst testing discussion and project-specific validation help reduce safety and reliability risks.

FAQ
Heat Exchanger Testing Laboratory FAQ
A heat exchanger testing laboratory may review thermal performance, airflow behavior, pressure drop, leakage, corrosion resistance, pressure safety and sample validation data depending on the product and project requirements.
Wind tunnel testing support should be confirmed according to available equipment, project data and sample requirements. If available, it can help evaluate airflow, pressure drop and air-side heat transfer performance.
Salt spray testing is used to evaluate corrosion resistance of materials, coatings or metal surfaces under controlled salt fog conditions. Test duration and standard should match the project requirement.
A 10,000-hour salt spray claim must be verified with real test documentation before publication or quotation. Buyers should request available reports or confirm project-specific testing requirements.
Burst testing evaluates how a pressure-bearing component behaves under increasing pressure. It may help review structural safety margin, deformation or failure behavior for selected heat exchanger projects.
If a real burst test video is available for the product or process, Domi can share it subject to project approval. If not available, a specific test plan may need to be discussed.
Please provide product type, drawing, working medium, inlet and outlet temperature, airflow or liquid flow rate, pressure conditions, capacity target and required report format.
Testing reports can support sample approval by documenting test conditions, measured data, observations and engineering review notes. Final acceptance depends on buyer requirements.
Domi can review leak testing requirements based on product structure, refrigerant, pressure and customer specifications. The testing method should be confirmed before production.
Testing location depends on available equipment, product type and project requirements. Some tests may be performed in-house, while others may require third-party laboratory support.
