Since the development of the portable oil tank cleaner, we have been carrying out the planning and development of new products and the design and manufacture of various special machinery for ships, including cleaners and various types of ventilation devices which support tank cleaning and gas-freeing operation centering on crude oil washing machines, energy-conserving air motor-driven davits, low-grade fuel oil treatment devices which protect large ship engines from inferior fuel oil, membrane-type controlled air dehumidification devices which enable high-precision dehumidification and are tough against oil contents, and churning devices for preventing the accumulation of sludge aimed at large land-based tanks.

Both on land and at sea, we boast an extensive track record in regard to execution management for tank cleaning and anti-corrosion work, the disposal of surplus water from dredging and reclamation work, and so forth, and we have received high acclaim.

Through the in-house manufacture of various types of fuel and combustion additives aimed at preventing air pollution, conserving energy, and maintaining equipment, we are making significant contributions in regard to energy problems from the perspective of reducing fuel consumption.
These are in a wide range of areas, including the chemical cleaning of ships and factories.

We carry out the development and sale of materials for the prevention of environmental pollution and products related to bowling.
