Activities of the company include the following:
- Feasibility studies,
- Design issues,
- Construction Works (Basic Designs),
- Procurement,
- Installation,
- Commissioning,
- Building and Equipment Maintenance,
- Rectangular Air Duct Production,
- Manufacturing of Special Parts (Tanks, Stacks etc.)

Feasibility Studies:

Prior to construction, when requested by clients, system selection studies and operational cost studies are done to optimize the investment. These studies can be done by the company in either case—whether or not design drawings have been provided by the client. Demta prepares the drawings, when necessary.

Design Issues:

While Demta is mainly concerned in the contracting of electro-mechanical works, engineering and design issues have always had the top priority in all constructions. The company tries to perform each design and engineering work with the highest quality possible.
There are two basic rules for the management team before starting working on any project, big or small:
- To understand every operating principle and to have the necessary information and documents, in order to be able to manage the entire system,
- To prepare shop drawings and system calculation reports before starting the works.

A highly qualified staff of engineers is always available to work on design issues. They do research and keep themselves up-to-date by attending seminars in Turkey and abroad.

In the design department, AutoCAD has been used for drawing production since 1993. There are at least seven engineers and six draftsmen who serve only for the engineering need of the company in the head office.

On the other hand, every site group has a separate group of designers and draftsmen according to their needs and these groups are under the control and coordination of the head office design group.
The main engineering and system design works of any contract are prepared in the head office. Then, the shop drawings and as-built drawings are usually completed by the site design group. When necessary, the head office engineering team helps the site design teams in order to complete the projects in time.

Additionally, Demta is in contact with other highly qualified design and engineering companies in those fields, in order to make sub-contracts and to take their support when necessary. That is to say that when there is a heavy workload in the company, Demta may choose to delegate some parts of common drawings to one of those groups as a subcontract; these groups are also supervised by Demta management.

The capabilities of the design team in the head office could briefly be defined as;
- Average daily production rate:
   • 6 A0-size drawings,
   • 50 A4-size calculation reports.

The engineering group has been being able to follow and use all international standards like BS, AMERICAN, SNIP (RUSSIAN), DIN etc. according to the nature of the contract.

Construction Works and Refurbishing Projects:

Demta has been working with different organizations in different areas of the industry since 1978. As a result of its prompt completion of its contracts and carefully carrying out projects in accordance with the clients' specifications, Demta is held in high esteem by its clients in Turkey and abroad. Being a dynamic group gives additional benefits to mobilize immediately whenever necessary in local projects and/or abroad.
The company has already worked in coordination with a number of local and foreign groups for lots of international projects. Furthermore Demta has a good contact network which is a valuable asset when starting out or bidding for new projects.

Procurement, Installation, Commissioning, Operating and Training:

The company specializes in all aspects of the following mechanical subjects.
• Procurement of all kinds of material supplies in a suitable time manner for fast track jobs.
• Installation of all kinds of electro-mechanical systems, including process equipment etc.
• Commissioning, operating and training of the completed system by itself.
The company comprises multi-disciplined engineers and technical supervisors; all of whom have extensive experience. They have been involved in many major national and/or international projects.

Building and Equipment Maintenance:

The company offers complete customer services together with maintenance for construction. The Demta service and maintenance is a special form of service which maintains the efficient operation of HVAC and other Electro-Mechanical Systems, by inspecting the plant operation via performance tests. This ensures that these plants operate as they are designed to—particularly concerning their recommended settings, and costs of maintenance and energy.

Manufacturing of Special Parts:

The company has factories in Çekmeköy and Tuzla, where some special mechanical items are manufactured for company-owned contracts. These products are:
• Steel Constructions with special design (stainless steel, carbon steel, aluminum etc.),
• Air Ducts,
• Tanks,
• Heat Exchangers.
