Technologies and Services

The Professional Engineers Essential for Plant Maintenance

We have approximately 400 engineers specializing in plant maintenance. To be able to handle various matters that occur at clients' plants, our engineers specializing in machinery, electricity and control, civil engineering and construction, and chemistry are always stationed at our engineering offices across Japan and provide technologies depending on clients' needs.
Valuing close communications between our plant maintenance division and related organizations, we are working on a cycle where technologies developed in maintenance work are used in engineering and technologies developed through engineering work are used in maintenance. At our company, we value this cycle to realize the continuous improvement of technologies in the engineering field ("plant creation") and in the maintenance field("plant protection"), and we consider this crucial to keep supporting our clients' plants.

Ratio of plant maintenance engineers in terms of specializations

We have 48% of maintenance engineers in machinery, 28% in electricity and control, 11% in civil engineering and construction, and 4% in chemistry. Utilizing technologies in each specialization forconstruction of new plants and expansion and enhancement of existing ones, we handle everything, including design, construction, and aftercare.

Wastewater treatment technology
  • Through mining wastewater treatment projects, we have acquired the necessary technologies and know-how.
  • Our preferred treatment method adds an alkalinizing agent to wastewater containing heavy metals to adjust the pH level, which solidifies the water's heavy metals in an ionic state for sedimentation and separation. Once the concentration of heavy metals in the water is reduced to below the effluent standard value, the water will be discharged.
Technology Proposals
  • Investigation, consideration, and planning for inquiries (questions and problems) regarding reaction processes and chemical properties.
  • Market research and feasibility studies on equipment for new business plans and proposals for concrete implementation.
