[Energy Saving] Reduce bathtub insulation costs by 40% to 70% and reduce carbon dioxide emissions by 30% to 70%.

Conventional heat pumps could not accommodate the water quality of baths, so they used to create high-temperature hot water with heat pumps and maintain the bath's temperature through a heat exchanger. The new product now allows for direct heating of the circulating water in the bath through a combination of a newly developed heat exchanger unit and a heat pump unit. With the realization of direct heating, it achieves energy-efficient operation, and since a buffer tank and circulation pump are no longer necessary, it can be introduced at a lower cost and in a more compact form compared to conventional systems.

Producing clean water with new ideas and technology! High-performance circulating filtration system [Free catalog available].

This catalog is a comprehensive catalog of circulation filtration devices handled by Science. Unlike conventional filtration devices that only keep water clean, Science's high-performance circulation filtration devices are characterized by their consideration for the environment and health, as well as energy-saving, labor-saving, and space-saving features. The bathtub heating devices come in a compact and easy-to-install electric heater built-in type, as well as a heat pump type that reduces both heating costs and CO₂ emissions. We can flexibly respond to anything related to water. We offer the automatic backwashing sand filtration device "PRT Series," the filter filtration device "KJO Series," the bathtub heating heater "SHS Series," and the bathtub heating heat pump "YHP." For anything related to bathtub filtration devices, please feel free to contact Science, the specialized manufacturer. *For more details, please refer to the PDF materials or feel free to contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
