We are looking for a skilled Design Engineer with experience in the fin-and-tube heat exchanger industry. The candidate will be responsible for designing, developing, and optimizing heat exchangers used in HVAC, refrigeration, air conditioning, industrial cooling, and thermal management applications.
Key Responsibilities
- Design and develop fin and tube heat exchangers, coils, condensers, evaporators, cooling coils, heating coils, and related components.
- Prepare technical drawings, 3D models, BOMs, and manufacturing documentation.
- Select appropriate tube materials, fin materials, fin spacing, tube diameter, circuiting, headers, and connection details.
- Use heat exchanger design software and engineering calculation tools.
- Support product development, customization, and value engineering projects.
- Coordinate with production teams to ensure designs are manufacturable and cost-effective.
- Review customer specifications and prepare technical proposals.
- Assist in troubleshooting design, production, and performance-related issues.
- Ensure compliance with relevant standards, codes, and customer requirements.
- Work with quality teams to resolve non-conformities and improve product reliability.
- Support testing and validation of heat exchanger prototypes and final products.
- Maintain design records, calculation sheets, drawings, and revision history.
- Collaborate with purchasing teams for material and component selection.
- Continuously improve existing product designs for better efficiency, durability, and cost reduction.
Required Qualifications
- Bachelor's degree in mechanical engineering, or Diploma in Thermal Engineering, or a related field.
- Experience in heat exchanger design, preferably in fin and tube heat exchangers.
