Hydrogen stations

Hydrogen stations

-Contributing to the realization of a hydrogen society-
Hydrogen gas, which can reduce carbon dioxide emissions, is expected to play a key role as a next-generation clean energy source.

We are constructing hydrogen stations to fill fuel cell vehicles with hydrogen gas. Such vehicles use electricity generated by electrochemical reaction with oxygen in the air to drive their motors.

Although hydrogen stations require design pressures exceeding 90 MPa, we will provide the same construction management as other equipment supplied to date.

Cryopreservation system maintenance

Cryopreservation system maintenance

Cryopreservation systems are a technology that utilizes the cold energy of liquefied nitrogen to store and preserve iPS sample cells in a wide range of fields including medical science and treatment, livestock, and agriculture.

Exhaust gas abatement systems

Exhaust gas abatement systems

Air-cooling combustion burner
Saan Burner

Most semiconductor process gases have many properties such as flammability, self-combustibility, corrosiveness, and toxicity.
Moreover, PFC gas with high GWP (Global Warming Potential) is also used.
Exhaust gas abatement systems (scrubbers) safely detoxify these gases.

We have been developing, designing, and manufacturing exhaust gas abatement systems (scrubbers) for many years. Based on the know-how gained, we provide the optimal equipment to meet customers' requirements.
We have a wide variety of exhaust gas treatment systems including combustion-type (air cooling/water cooling), plasma-type, adsorption-type (dry type), and scrubbers.

Completion inspection (High Pressure Gas Safety Act)

Completion inspection (High Pressure Gas Safety Act)

The hazards of high pressure gas equipment make conformance to the requirements of the High Pressure Gas Safety Act essential.
Regulatory reforms have enabled private companies with inspection technology and high reliability to perform completion inspections to ensure that equipment meets those requirements.

We have been designated by the Minister of Economy, Trade and Industry as a designated completion inspection body, and nationwide we carry out reliable, professional completion inspections at facilities to which general high pressure gas safety regulations apply.
Our service is also available on public holidays and has been highly evaluated. (Ability to meet requests is subject to inspection schedule.)

Note: After making the completion inspection, if it is recognized that the company conforms to the technical standards, we will issue a completion inspection certificate. Please submit a copy of the completion inspection certificate and the completion inspection notification of the designated completion inspection body to the competent administrative authority.

Safety inspection (High Pressure Gas Safety Act)

Safety inspection (High Pressure Gas Safety Act)

After a completion inspection has been made, mandatory safety inspections are required on a regular basis to check the maintenance status of high-pressure gas equipment. (Depending on the amount of processing, equipment may be exempted from safety inspections.)
Due to regulatory reforms, private companies which have high reliability and inspection technologies are now able to carry out safety inspections to check maintenance status.

Our company has been designated by the Minister of Economy, Trade and Industry as a designated safety inspection body and can carry out safety inspections of equipment to which safety regulations such as general high pressure gas safety regulations, liquefied petroleum gas safety regulations, and safety regulations for industrial complexes apply. (Safety regulations for industrial complexes, etc. are limited to certain areas). We carry out reliable safety inspections under the supervision of professionals.

Note: After making the safety inspection, if it is recognized that equipment conforms to the technical standards, we will issue a safety inspection certificate. Please submit a copy of the safety inspection certificate and the designated safety inspection body's safety inspection notification to the competent administrative authority.

Operation management of gas supply equipment

Operation management of gas supply equipment

Operation management of gas supply equipment

Most customers conduct continuous operations at sites that use industrial gas. The electronics industry, in particular, uses difficult-to-handle gases such as high-purity gas and specialty gas 24 hours a day, 365 days a year.
Such operations require stable gas supply, and gas supply equipment operation management is a key point.

In order for our customers to use these gases safely and with peace of mind, gas professionals from the Taiyo Nippon Sanso Group, including our qualified personnel and internal certified personnel, are responsible for the operation management and day-to-day inspection of high-pressure gas equipment, gas plants, special gas supply equipment, and even gas exhaust equipment.
