Job Title:

Design Engineer - Hermetic Compressor

No. of Positions:

- 1

Job Location:

- Hyderabad

Skill Set:

- ANSA, Star CCM+

Domain Knowledge:

- Deep understanding and knowledge in fluid mechanics, multiphase flow and heat transfer.
- Robust backgrounds in Computational Fluid Dynamics (CFD), and experience with heat transfer & fluid flow analysis
- Excellent problem-solving and analytical skills

Job Description:

- Develop 3D CAD concept models, layout configurations, and component stack-ups for a multi-cylinder reciprocating compressor platform utilizing a 75kW integrated motor.
- Design rugged, pressure-resistant ductile iron castings/housings capable of withstanding high operating pressures (typically up to 2.8 MPa / 28 bar) and meeting strict international pressure vessel codes.
- Optimize the crankcase, crankshaft, connecting rods, pistons, and valve plates for high volumetric efficiency, minimized dead-space, and low vibration.

- Optimize the crankcase, crankshaft, connecting rods, pistons, and valve plates for high volumetric efficiency,



minimized dead-space, and low vibration.
- Design the internal gas flow paths for suction cooling of the motor or develop external water/glycol cooling jackets to manage the 75kW thermal load.
- Engineer an advanced internal lubrication system (oil pump, internal channels, oil separator, and filtration) ensuring constant oil supply to critical high-wear bearing surfaces while minimizing oil carryover into the HVAC system.
- Guide engineering analysts on finite element analysis (FEA) for stress/fatigue on moving parts and computational fluid dynamics (CFD) for pulsation and gas flow through valve plates.

Requirements:

- CAD Mastery: Proficiency in advanced 3D modeling and drafting using SolidWorks including geometric dimensioning and tolerancing (GD&T;).
- Ammonia / R717 Expertise: Comprehensive understanding of the thermodynamic properties of ammonia, chemical compatibility parameters, and dedicated safety protocols.
- Hermetic Motor Know-how: Practical understanding of hermetic/semi-hermetic motor construction, particularly thermal dissipation, electrical insulation requirements in harsh chemical environments, and terminal pin sealing.
- Manufacturing Processes: Deep knowledge of casting techniques (ductile iron, aluminum), precision machining (micron-level tolerances for cylinders/pistons), and valve assembly dynamics
