We undertake strict checks in process control, testing and evaluations, inspections, and other activities to deliver quality products customers can use with peace of mind.
Sales
Solutions-based sales
Our highly experienced specialized staff propose products selected from our wide-ranging lineup best suited to customer needs.
After-sales service
Reliable manufacturer inspections
Our staff at service centers across Japan handle after-sales services from the introduction of our company’s products through maintenance, including adjustments, repairs, and statutory inspections.
The field of RIKEN KEIKI can be any places
where gases may occur and any industries
where gases are used.
Semiconductor manufacturing (pre-processing)
The manufacturing processes for semiconductors that play essential roles in our everyday lives incorporate various gases, centered on special material gases.
Gas leak detection systems prevent accidents due to these gases.
Petroleum refining
The petroleum products and petrochemicals (including intermediary products) used in various industries are produced in various processes, starting with processes for refining raw crude oil. Gas detectors are used to ensure safety in refining and associated activities.
More
Steelmaking
Steelmaking involves various processes and materials ranging from raw iron ore to completed steel products. Because the gases generated in each process pose flammability, toxicity, and other risks, gas detectors are deployed to keep workers and facilities safe.
More
Power generation
Gas detectors are used in the power generation industry, a key element of our social infrastructure, to keep workers and facilities safe, especially at thermoelectric power plants and biomass power plants, which generate power by burning fuel, and at geothermal power plants, which handle terrestrial heat.
More
Municipal gas
Municipal gas is produced by compounding the raw material of LNG with several other gases to regulate parameters such as heat value and combustion rates.
Gas detectors are used to measure calorific value, which determines the quality of municipal gas, and to monitor for flammable gas leaks.
Waterworks and sewers
Waterworks and sewer systems are important elements of the social infrastructure that support our everyday lives. Gas detectors are used in these industries to help keep workers safe.
More
Food products manufacture
Gas detectors are used to keep workers safe in various production processes for the food products that enrich our lives.
Automobile production
The auto industry, one of Japan’s core industries, involves a broad range of related industries, including auto parts production, machining, and assembly. Gas detectors are used for various applications, including checking the safety of working environments.
Shipping
The shipping industry draws on a wide range of ship types to transport various cargo including crude oil, LNG, containers, iron ore, and wheat and to support global logistics. Gas detectors are used to manage safety on board these ships.
Fire and police departments
Sites of accidents and disasters pose high risks associated with flammable gases, oxygen deficiency, and toxic gases. Gas detectors boost safety for the courageous first responders who tackle the challenges in this field.
Pharmaceutical production
Pharmaceutical production processes involve chemicals, organic solvents, and other materials. Gas detectors maintain safety in these working environments.
Civil engineering and construction
Gas detectors are deployed in sealed spaces exposed to gas buildups, such as construction sites for underground tunnels, buildings, and other facilities, to prevent accidents involving oxygen deficiency, toxicity, or other factors.
Volcanoes and hot springs
Volcanic gases emitted from volcanoes can contain harmful gases such as hydrogen sulfide (H2S) and sulfur dioxide (SO2), in addition to carbon dioxide (CO2).
In addition, volcanic hot springs may contain gases such as hydrogen sulfide (H2S) and natural gas (mainly methane). Gas detectors are used to ensure safety in indoor locations and other places susceptible to gas buildup.
Research facilities
Research facilities often include enclosed interior spaces and use various gases and chemicals, such as the carrier gases used in analytical equipment and liquid nitrogen. Gas detectors are essential to assuring the safety of these working environments.
Papermaking
The process of producing pulp from wood chips produces sulfur compounds and other byproducts.
These byproducts are recovered to minimize their release into the environment.
Gas detectors are used to assess environmental impact and workplace safety.
