Jos started working out of his house in Phitsanulok, Thailand. With the increase of activities, the company expanded and after approximately one year a move was made to rented premises. Computers were introduced and modern office equipment was purchased. At the same time, in 1989, the first office staff was employed.

In the years to follow activities again expanded. More equipment and staff was added to the portfolio and sales increased. A new move was made to an office close to the previous one.

In January 1996, the workload increased to a point where it became too much for one person to handle and Jos asked a son of friend to come and join him. Danny Pauw started working in August 1996 and helped developing the company.

In 1997, Namtip Duffield was hired. Namtip is currently a member of the Board of Directors of the company and manages the financial and total office administration of Souer.

Souer became more active in the support of the major offshore companies and established itself as a reliable supplier for a wide, but selective, range of technical equipment.

The first technical personnel were employed and soon the office became too small. New offices were built and included a small workshop where small engine parts were serviced.

In the beginning of 2004 Souer bought a plot of land and designed a new large office building. The official opening of the new premises was on October 4, 2004.

In 2005 the first attempt was made to start packaging small generators. Souer was awarded a project by CUEL Ltd for the supply of 10 small gensets. After a learning curve this resulted in a competitive and high-quality product.

In the same year, Chevron Offshore Thailand Ltd awarded Souer a contract to build a number of 350 kW gensets.

Because of this new development, Souer completely rebuild their workshop into a modern facility.

The packaging of generator sets is still one of the main business of Souer Co., Ltd.

Efforts are made to expand this further for other applications as well.
