We have completely renewed the products and catalog related to the pressure-resistant explosion-proof liquid filling system!!

This is a fully automatic liquid filling machine for explosion-proof 18L cans/one-dan cans. All electrical equipment used is compliant with safety regulations, making it easy to comply with fire safety laws.

This is a pressure-resistant explosion-proof fully automatic filling machine designed for compact space, capable of completing the process from the transport of empty cans to palletizing within an explosion-proof area. - The filling valve is easy to disassemble and clean, offering excellent sanitary properties. - The materials for the valve's wetted parts can be selected from SUS304, SUS316, SUS316L, or PTFE (Teflon). - All equipment, including the control panel, can be installed in the explosion-proof area. The photo shows a unit type, but we also accommodate layout changes based on installation location or customer requests, such as modifications to a straight line configuration. Since both the hardware and software of the control unit are produced in-house, it is possible to communicate with higher-level PLCs or PCs via serial communication for data collection and CSV output. 【Equipment Configuration】 1. Depalletizer 2. Uncapper 3. Filler 4. Weighing scale (certified scale) 5. Capper 6. Labeler 7. Re-capper 8. Palletizer * It is also possible to select only the necessary parts or add a nitrogen filling machine (N2 purge machine).

This is a fully automatic drum filling machine that can be used in hazardous locations. It features a full pressure-resistant explosion-proof design that allows all equipment to be installed within explosion-proof areas.

All electrical equipment being used is explosion-proof and can be installed in explosion hazard areas. Unlike intrinsically safe explosion-proof specifications, there is no need to install barriers in safe locations. By simply supplying power and air, cumbersome wiring and piping work to safe locations can be avoided, reducing installation costs. *Electrical equipment used in hazardous locations, even if it has explosion-proof certification overseas such as IECEx or ATEX, cannot be used in Japan unless it has passed domestic explosion-proof testing. Our products have obtained domestic explosion-proof certification (TIIS certification) and can be safely used in explosion hazard areas.

This is a semi-automatic filling machine compatible with one-gallon cans and poly cans, suitable for use in hazardous locations. The filling nozzle is easy to disassemble and clean, ensuring excellent sanitary conditions.

- The filling valve is easy to disassemble and clean, with excellent sanitary properties. - In addition to SUS304, materials for contact parts can also be selected from SUS316, SUS316L, and PTFE (Teflon). - A drip tray to prevent liquid spillage is standard equipment. - It can be used in conjunction with small containers such as one-gallon cans and poly cans, as well as drum cans. Our semi-automatic filling machine for one-gallon cans/poly cans is composed of equipment certified for explosion-proof use in Japan, allowing for safe operation in hazardous locations (note: non-explosion-proof models can also be manufactured). By installing a certified weighing scale at the end of the filling machine, it also complies with JIS standards for automatic weighing. Both hardware and software are designed and manufactured in-house, enabling customization to meet customer needs. *Electrical equipment used in hazardous locations must have domestic explosion-proof certification in Japan, even if it is certified for explosion-proof use overseas, such as IECEx or ATEX. Our products have obtained domestic explosion-proof certification (TIIS certification) and can be safely used in explosion-proof areas.

This is a semi-automatic liquid filling machine compatible with IBC containers/metal containers that can be used in hazardous locations. Containers can also be loaded directly with a forklift.

Our container filling machines are composed of equipment certified for explosion-proof use in Japan, allowing for safe operation even in hazardous locations (non-explosion-proof models are also available). The cylinder-type filling valve is easy to disassemble and clean, ensuring excellent sanitary conditions. The wetted parts include diaphragm valves made of stainless steel (SUS304, SUS316, SUS316L) and all-PTFE (PTFE/PFA) options. Both hardware and software are designed and manufactured in-house, enabling customization to meet customer needs. We can also manufacture upstream and downstream transport devices, contributing to labor-saving and efficiency in factories. Additionally, we offer a combined type for both drum and container filling. This is ideal for customers with small lot and diverse production needs, or those with space constraints for filling. Furthermore, by installing a weighing scale on the filling machine side, we can accommodate JIS standards for automatic weighing. For more details, please refer to our catalog.

This is a drum filling machine that can be used in hazardous locations. The filling nozzle is cylinder-operated, providing good responsiveness and enabling high-precision filling.

Our drum filling machine is composed of equipment certified for explosion-proof use in Japan, allowing for safe operation in hazardous locations (note: non-explosion-proof models can also be manufactured). Additionally, by installing a certified weighing scale after the filling machine, we can comply with the mandatory certification for automatic scales (JIS compliance for automatic scales). We can also manufacture conveyor systems such as front and rear drive conveyors, so please feel free to consult us. 【Features】 - The filling valve is easy to disassemble and clean, providing excellent sanitary properties. - In addition to SUS304, materials for contact parts can be selected from SUS316, SUS316L, and PTFE (Teflon). - Standard features include an automatic drip tray to prevent liquid drips and a mechanism that automatically retracts the nozzle when it collides with the container during descent. *Electrical equipment used in hazardous locations must have undergone domestic explosion-proof certification in Japan, even if it has been certified for explosion-proof use overseas (such as IECEx or ATEX). Our products have obtained domestic explosion-proof certification (TIIS certification) and can be safely used in explosion-proof areas.

The "Mechanical Stitch 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 to 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.
