[Case Study of Solution Proposal] Implemented oil temperature management for hydraulic units, achieving stable operation of equipment! A catalog with a simple explanation in 6 pages of manga is now available!

An oil chiller that significantly reduces maintenance costs for pump repairs and oil leaks by being installed on the hydraulic unit! Space-saving and easy to install!

【Proposed Solution Case】 ■Conventional Method 　・Using a natural convection hydraulic unit ■Issues 　・During summer and other times of high outdoor temperatures, heat dissipation efficiency decreases, leading to increased oil temperature 　・Oil leaks occur due to seal deterioration 　・High maintenance costs due to pump failures ■Ideal Condition 　・The oil temperature of the hydraulic unit is maintained below a constant temperature year-round 　・No oil leaks occur 　・Pumps do not frequently fail 　・Production is not halted due to pump replacement maintenance ■Our Proposal 　・Install the compressor-type oil chiller VSC-N series ■Benefits 　・Achieve oil temperature management for the hydraulic unit 　・Resolve oil leaks caused by seal deterioration 　・Reduce time and costs for pump replacement 　＋α Implement preventive maintenance with external output for oil temperature alarms (IoT compatible) *For more details, please refer to the related product catalog or feel free to contact us.

It's now common for oil chillers to be non-Freon! It's possible to eliminate the cost burden associated with Freon.

The "VSC-N Series" is a non-Freon oil chiller that uses the non-Freon refrigerant HFO-1234yf. It is exempt from the "Freon Emission Control Law," eliminating the need for collection and destruction by designated contractors and the obligation for regular inspections, thereby removing the cost burden associated with Freon. It is now standard for oil chillers to be non-Freon. 【Features】 ■ Zero Freon management workload with the new refrigerant HFO-1234yf ■ High precision control with hot gas bypass, ±0.1℃ ■ Available in 1500W, 3000W, and 6000W types ■ IoT compatible, allowing for setting changes from touch panels and PLCs ☆ We are also offering free service for test units. *For more details, please refer to the PDF document or feel free to contact us.

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 even 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.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for 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! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.
