Department of Mechanical Engineering – Auto & Refrigeration/ Air-conditioning

Mr. John Kwamena Amos, HoD

Since its establishment in 1954, the Department of Mechanical Engineering has been the flagship of the institution. The department runs a broad spectrum of programmes which meet the needs of Manufacturing, Mining, Transportation and Engineering industries including oil and gas in Ghana.

The department seeks to train highly competent graduates who can demonstrate a great sense of knowledge and skills in the field of Mechanical Engineering in a bid to bridge the gap between work and school. The department also aims to develop a close working relationship with the world of work in order to provide solutions to meet their operational challenges. To train students in 4-year BTECH Automotive and Air Conditioning & Refrigeration Engineering.

The department intends to expose students to the state-of-the-art designs and practices of Mechanical Engineering in order to meet the technological advancement of modern industries in Ghana.

The objectives of the Mechanical Engineering Department include the following:
1. To focus on middle-level manpower entrepreneurial and business training with emphasis on the acquisition of manufacturing, adaptive design and maintenance skills.
2. To increase access to career-focused tertiary training, while encouraging female enrolment in Mechanical Engineering programmes;
3. To design curricula in response to the changing needs and expectations of industries.
4. To offer short courses for industries to upgrade their existing operations in line with modern PLCs, mechanical and mechatronics systems.
5. To integrate Scientific and Engineering education with business in order to promote creativity.
To expose students to hands-on applications of Mechanical Engineering Automotive technology and processes using Autotronic Laboratory.

The Department of Mechanical Engineering runs the following programmes,
1. Bachelor of Technology Automotive Engineering
2. HND Automotive Engineering
3. HND Refrigeration and Air-conditioning Engineering

The Department intends to run the following programmes beginning 2018/2019 academic year:
1. Diploma in Automobile Engineering
2. Motor Vehicle and Transportation Engineering
3. Bachelor of Technology in Motor Vehicle and Transportation Studies
4. HND Refrigeration and Air-conditioning Engineering (Evening).

The department offers the following non-tertiary programmes:
1. Motor Vehicle Technician I, II & III
2. Welding Advanced Craft Course

Modules being studied at the Autotronic Laboratory include: Automotive Air-Conditioning Training, Emission Control System, Auto technology- Engine starting system, Auto technology- Electrical system, Auto technology- Engine sensors and Control and Auto technology- Electrical Power.

Collaboration with other departments within the University
The Mechanical Engineering Automotive and Refrigeration shops continue to provide vital services in the areas of maintenance and repair of vehicle, engine servicing, refrigeration and air-conditioning services and repair of industrial machines in the Interior design and Fabrication workshop. The Welding Workshop and its equipment are being used by Sculpture students from the Visual Arts Department for their practical work. In addition, other departments have been using the mechanical workshop for fabricating metal products for use in their departments. Our students are now directly involved in a weekly hands-on practical attachments in servicing air-conditioners on campus.

Collaboration with industry
The department is arranging with major international players in the oil and gas industries such as Oilfields Machine Shop (OMS), APAVE International, HYTEC Services and Plot Ghana a cocoa Processing Company in the Metropolis to facilitate students’ weekly hands-on industrial training programmes. Already, companies such as VULCO (RANA Motors) ANIGHART, Frank Motors, Av Agharkwa Motors, Benz Motors, Twum Motors, Master Antho., and German Motors are offering weekly skills training for our auto students. Some of our graduands have also been employed by Tullow Oil Company, MANTRAC and Kwansa Motors, Anglogold Ashanti, Goldfields Ghana Limited, SANDVIC, V.R.A, Schlumberger, SEM, Novotel Hotel, MODEC Ghana, Antrak Group.

Workers of industries are benefitting from the ongoing HND (Mechanical Engineering) evening school programme as well as short courses for SMEs and BTech topup.

Services offered by the Department
The department offers the following services to the polytechnic community:
1. Oil and filter change
2. ATF level check
3. Gear box oil change check
4. Radiator flushing
5. Cancel of check engine
6. Wheel balancing
7. Vehicle valeting and washing services
8. Wheel alignment checks

The following proto-type machines and equipment have been produced by students; however, they are limited by financial constraints.
1. Design and Construction of split –type air conditioner;
2. Design and Construction of Refrigeration trainer;
3. Design and Modification of an open-type Refrigeration Compressor;
4. Construction of a cold storage trainer;
5. Design and Construction of a battery powered tricycle



Everything that I learned at TTU really helped put me above the competition in the field of mechanical engineering.
