Only recently has Duta Firza become a manufacturer for pressure and temperature instrumentations. Working together with ASHCROFT, the facility located in Sentul - Bogor 16810, is striving to fulfill the high demands of these instrumentations.

Not only does it speed up the process of transportation, but it provides the fact that these instrumentations, based on a design and quality assurace system made by an American company, are indeed made 100% locally in Indonesia. Duta Firza is aiming to satisfy customers this way.


PT Duta Firza Technologies (Duta Firza), was appointed in 2010 to grow sales in Indonesia. One important factor in the success of competing in this region, is the need for quick delivery and readily available stock, as well as meeting governmental requirements for local content.

Ashcroft and Duta Firza joint up to set up a local assembly operation in Jawa Barat to assemble the Ashcroft products

As an EPC contractor as well, Duta Firza has been delivering EPC projects which can date back to 1993. EPC projects were conducted and has been completed in certain regions of Indonesia, such as Makassar, Kalimantan, Surabaya, and Bali.

The EPC division would consist of two categories; engineering and project management. Duta Firza has delivered contracts with large and major oil and gas companies such as Pertamina, Shell, and Indonesia Bulk Terminal.

A contract with PT. Shell Indonesia of 1 year, requires the construction of a tank farm which then indicates the needs of construction of tanks of different sizes as well as the foundations and drainage systems that must go with it.

In 1993, Duta Firza delivered an EPC contract with PERTAMINA, lasting for 3 years and was an EPC of an oil transit terminal in Amuk, Bali. This contract required Duta Firza to expand the needs of the client within this contract, which then includes an EPC for civil works (such as preparing the land, mooring the dolphins, supporting facilities, etc), an EPC for mechanical works (such as diesal storage tanks, petrol storage tanks, product pump stations, etc) and an EPC for electrical instrumentation and automation works.

In 2013, through PT GPS, Duta Firza was awarded for the Provision of topsides EPC for Bukit Tua FPSO projects. The project enriched Duta Firza’s portfolio and strengthened full EPC capabilities in advanced fabrication technologies.   

In this way, the EPC division of Duta Firza needs to be divided into two categories, in order to effectively divide the tasks and carry out the contracts with professionalism. The engineering team focuses on the design and process of the materials and facilities needed for the EPC, and thereby includes all aspects; mechanical, civil, and electrical. The project management team focuses solely on the planning, scheduling, cost control and documenting of the EPC.

Duta Firza has provided computer equipment (software and hardware) in the oil and gas market. Providing computer services does not have any direct relevance to the oil and gas industry, however being able to fund and help another oil and gas company would, in hopes, improve relations. In this way, Duta Firza does not only think of securing its future economically and financially, but also by creating close associations with others that can prove to become convenient, in the future.
