Our company is engaged mostly in servicing the geothermal, oil and gas industries.DESCO‘s humble beginning occured more than three (3) decades ago. Our company started first as a machine shop in a small facility in Bicutan, South of Manila. Then it continued to expand operations and moved to its present location in Sucat, Muntinlupa City in 1982.In the early 1990′s, DESCO embarked on acquiring larger equipment. Equipped with our expertise, our company became the first one-stop shop service provider for the geothermal, oil and gas companies in the Philippines.

In partnership with Thomason Mechanical Corporation (a Wood Group International Company), our company further expanded business operations by rehabilitating power plants in year 2000.
