[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.

Case Study of Replacing Blower with Ejector as a Vacuum Source [Background] "Space-saving of the equipment is a challenge" The blower currently in use takes up a lot of space, so we received inquiries about a vacuum source that can be installed in a space-saving manner. Additionally, it was necessary to continuously operate the blower even when the equipment was not in use, leading to waste.

Parking space management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, enabling efficient parking lot operations. For large parking lots, we recommend the "Floor Management Method" and "Block Management Method," which focus on cost reduction. Sensors are installed at regular intervals to count and manage the number of passing vehicles. This method offers the advantages of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 For smaller facilities, we recommend the "Parking Space Management Method," where sensors are installed in each parking space to display availability with high accuracy. By providing reliable occupancy information, this method helps reduce unnecessary entry of new vehicles and ensures safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8

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 kept to a minimum. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
