Job Summary
Aldelano Corporation is seeking a highly skilled and hands-on engineer capable of independently designing, building, installing, commissioning, troubleshooting, and maintaining industrial solar-powered refrigeration systems, particularly our 40-foot ColdBox units.
The ideal candidate must have strong technical expertise in mechanical refrigeration, electrical systems, solar energy, inverters, battery storage, power management, and engineering cost estimation.
The candidate must be able to design and build a complete ColdBox refrigeration system from scratch, including calculating its cooling capacity, energy consumption, solar requirements, and overall construction cost.
Key Responsibilities
Refrigeration System Design & Fabrication
Design and build complete industrial refrigeration systems for 20-foot and 40-foot ColdBox containers.
Calculate cooling loads, refrigeration capacity (BTU/hr, kW), and system efficiency (COP).
Select and size compressors, condensers, evaporators, expansion valves, refrigerant piping, and insulation.
Supervise mechanical fabrication, installation, testing, and commissioning.
Electrical & Power Systems
Design electrical distribution systems, wiring diagrams, control panels, and protective circuits.
Calculate electrical loads, compressor starting currents, power requirements, and daily/monthly energy consumption (kWh).
Integrate refrigeration systems with solar, battery, inverter, generator, and grid power supplies.
Troubleshoot and maintain industrial electrical equipment and control systems.
Solar, Inverter & Battery Engineering
Design and size solar PV systems based on refrigeration energy demand and available solar irradiation.
Calculate solar panel capacity (kWp), inverter capacity (kW/kVA), and battery storage requirements (kWh/Ah).
Determine battery backup duration, charging requirements, and generator capacity.
Design hybrid power systems with automatic switching and energy management controls.
Optimize system efficiency and minimize operating costs.
Manufacturing, Costing & Project Execution
Develop engineering drawings, technical specifications, bills of materials (BOMs), and cost estimates.
Calculate total construction costs, energy costs, and maintenance expenses.
Supervise fabrication, component assembly, installation, and quality control.
Lead system testing, commissioning, and performance verification.
Develop preventive maintenance schedules and technical documentation.
Qualifications & Requirements
B.Sc. or HND in Mechanical, Electrical/Electronic, Mechatronics, Refrigeration Engineering, or a related discipline.
Minimum of 5 years of practical experience in industrial refrigeration, electrical engineering, or integrated energy systems.
Proven ability to design, build, and troubleshoot industrial refrigeration or cold-storage systems.
Strong knowledge of solar PV, hybrid inverters, battery systems, generators, and electrical power distribution.
Excellent understanding of cooling-load calculations, energy consumption, and equipment sizing.
Proficiency in engineering design software such as AutoCAD, SolidWorks, PVsyst, or equivalent tools.
Ability to prepare technical drawings, project budgets, and comprehensive cost estimates.
Experience with industrial automation, PLCs, and energy management systems is an advantage.
COREN registration or relevant professional certification is an added advantage.
Expected Deliverables
The successful candidate must be capable of:
Designing a complete 40-foot solar-powered ColdBox refrigeration system.
Calculating refrigeration capacity, electrical consumption, solar requirements, inverter size, and battery capacity.
Preparing engineering drawings, component specifications, and construction cost estimates.
Leading fabrication, assembly, installation, and commissioning.
Delivering a fully functional, energy-efficient ColdBox with documented performance and maintenance requirements.
Candidate Selection
Shortlisted candidates will undergo a practical technical assessment to demonstrate their ability to design a ColdBox refrigeration system, calculate its energy requirements, select suitable components, and estimate manufacturing costs.
Important: This position requires a multidisciplinary, hands-on engineer with proven design and fabrication capabilities, not solely a refrigeration technician, solar installer, or maintenance engineer.
Immediate resumption is required.
Minimum qualifications
BA/BSc/HND
How to apply
Interested candidates should submit their CV, relevant qualifications, and evidence of previous industrial refrigeration or solar-powered engineering projects.to: engineering@aldelano.com using the position as subject of email.
